Calculator Module Generator

The new version of the Calculator Generator is online! Tell me what you think :)

What is new in the v1.1:
- change the calculator button label
- change the fields order
- copy fields and functions
- use advanced math functions: floor, round, power, root, modulo, random, date
- actions for advanced users: save and load a plain text config file
Fixed bugs:
- correct display of "|" in the Result field
- "%" in the result text now does not corrupt the language file
- automatically add a multiplication operator (*) if an operator in a formula is missing.

You can see the comments on the previous release by clicking the link Older Comments in the upper right corner.

Hi Ward,
I checked the last generated calculators and find one with an extremely long name. Is it yours? If so, try to generate it again with shorter name. I can't say if this is the problem but I didn't find anything else in the structure of the calculator.

Thanks, Gui
Your idea is great, but it will require javascript to be included in the generated module. That's something I prefer to avoid because not every Joomla instalation has the same js library. Also the calculator module could become in conflict with another js plug-in.
May be I will add js functionalities in some future version of the generator but I have no exact plans yet. Your proposal will definitely be included in such a version.

Hi Andre,

- How would you recommend I add an image to the results output?
This is the easier question. You can use HTML tags into the result field. For example you could write:
<img src='url_of_an_uploaded_image' />
or use an id with a div tag like:
<div id="my_image"></div>
and then add a background in CSS: url, width and height of the image you've uploaded somewhere on you site.

- What would be the best way to require each input field to have a value before submitting the form?
This is the tricky one. If you want the form to check if the required fields are filled in and does not submit at all, if they are not, you will need some javascript. You could modify the "mod_your_module_name/tmpl/default.php" file of your module (after downloading it) and use the Joomla methods described here: http://docs.joomla.org/Form_validation.

Thanks Andre
I am glad you like it.

Hi, Elizabeth
The reason for the warning could be a dividing by an input field. For example: Result = 10 / numFieldX. Your PHP processor decides that numFieldX could be zero (and it is quite right because if the user doesn't fill out the field it will be evaluated as zero) and displays the warning. This won't mess with the calculations but the warning will be displayed.

- You can just turn off the warning (open php.ini file on your server and change the row "display_errors = On" to "display_errors = Off". This is the Joomla recommended value for production sites).

- If you can't edit your php.ini file, modify the calculator by creating a middle result which adds some value to the field you want to divide by. For example: Result1 = numFieldX+1

This will fool the PHP processor to think that Result1 couldn't be zero. Then edit the main formula like this: Result = 10 / Result1 and the warning will be gone. Of course, you have to be careful not to change the final result your calculator will produce.

If you can't be sure the user will always enter a value into the divisor field you have to add a conditional statement to the middle result. Otherwise PHP will display the Division by zero warning in case Result1 becomes zero.

Hi, F.J.Rubio

In your page there is an additional span tag around the calculator button <span class="art-button-wrapper"> It is styled with positon: "relative" so the button is aligned to this wrapper and not to the original form tag. The span also has no width and an overflow set to "hidden". This means that everyting inside the span will be hidden including the calculator's button.

You could:
- remove the wrapper
- or style it with an appropriate width
- or change its overflow from hidden to visible

Hi, Josh

the Generator supports Joomla 1.6+ sites only. I don't know what is the desired structure of a Joomla 1.5 module. I am sorry you can't use your calculator with your site.

The new styles of the calculator fit perfectly to the site. It's great!

Open this file on your Joomla installation:
your_joomla_site / modules / mod_your_calculator_name / tmpl / css / default.css
Edit and save, then refresh.

Thank you, Robert, for your ideas.

It is possible to send the user inputs and results to an e-mail address. I will try to include this in the next version.

Storing the results into a database will change the basic structure of the Generator. It won't produce a tiny calculator module but a much bigger survey component. May be some day I could write another generator with such functionalities.

Hi, Adonis
I really can't give you an advice how to style you module. It depends much on the design of the site and your requirements. You could try to delete all the styles from the deafult.css file and write your own from scratch, so you will be able to position all the elements the way you want them.

Hi, Adonis,
your template css file is styling the elements with class .button with "height: 100%". This causes the calculator button to stretch 100% to the top.
You could:
- remove the 'class="button" ' from this module file: your_joomla_site / modules / mod_your_calcualtor_name / tmpl / default.php
or
- add an appropriate height to your module css like: "#calc-button {height: auto;}"

Hi, Deanna
You can change any color, font or position of the calculator elements by editing the module css file:
your_joomla_site / modules / mod_your_calculator_name / tmpl / css / default.css
For example:
1. Add at the end of the default.css file this line:
#calc-button {color: blue;}
2. Add at the end of the default.css file this line:
#calc .calc-input>label {border-left: none;}
Save default.css file and refresh your site.

Hi, Deanna
The only yellow element in the calculator default design is the left border of the labels. May be you didn't target the labels right. Try to add a style like:
#jform_your_variable_name-lbl {border: none;}
Don't forget to insert the name of your variable in the code above.

Hi mel,
I don't understand what kind of options do you want to configure? This site generates a module which is preconfigured by you before download. Please, check the Step-by-step Tutorial for a detailed example of such configuration.

Thanks, Justin!
You could use the general condition structure to achieve AND / OR logic. For example:
1. If you want to test X=3 AND Y=5 create two nested conditions:
if (x=3) {
      if (y=5) {
          do something
      }
}
2. If you want to test X=3 OR Y=5 create two parallel conditions inside a separate formula then test the result:
Z = if (X=3) { +1 } if (Y=5) { +1 }
if (Z>0) { do something }

Thanks, Mike!
No, the Generator does not work with anything else except Joomla 1.6+ Sorry

Hi Jonathan,
you can edit the result texts from the language file of the module: your_joomla_site / language / en-GB / en-GB.mod_your_module.ini (you can use any text editor to edit this file)

I was thinking to create site accounts but then decided that people have so many usernames and passwords for different sites so if I can spare them one more I better do it :)
You can save your work by clicking Advanced Actions and Save Config button. When you come back later go to Advanced Actions again and load the previously saved config file. (You can also edit the config file with a prefered text editor if you like)

Hi Giuseppe,
I am not sure what causes your problem. What web server do you use? Apache or IIS? If it is IIS, I guess the problem is in the Joomla class JURI which tries to guess the address of the calling page. It is not a good idea to mess with the Joomla core, so I suggest you to open this file of your module:
your_joomla_site / modules / mod_your_calculator_name / tmpl / default.php
and replace
htmlspecialchars(JFactory::getURI()->toString())
with
htmlspecialchars("https://www.spedizionidagliusa.com/preventivi.html")

Unfortunately if you move the module to another page you will have to change the URL again.

Thanks, Gabor!

And my answers to your questions:

1. Yes it is possible one calculator to produce two or more results (in any unit). Just create the desired number of formulas and then add them to the result field. Most of the demo calculators do so. For example you can check Days Converter Demo where there are 5 different results (and different units) for number of days, weeks, hours, minutes and seconds in a range of days.

2. Yes, you can add HTML tags to the output. To achieve your goal you will also need to set a conditional text results. Check the last paragraph of the Coin Flipping Demo and examine the way the result is formatted. Click the Result text button and add some HTML to the fields. For example, replace "You win!" with "<h1><a href="#">You win!</a></h1>". Then test the calculator and see what will happen when you win the game.

Thanks TomVai

I fixed the issue and you can now generate your module again.

If you prefer you could open this file of your module:
your_joomla_site / modules / mod_your_calculator_name / mod_your_calculator_name.php
and replace all occurences of variables definitions:
$varYourVar=preg_replace('/[^0-9.\-]/','',$varYourVar);
with:
$varYourVar=preg_replace('/[^0-9.\-]/','',str_replace(',','.',$varYourVar));

Hi, Hans
You can change the format of the output by clicking on the result name in the Result Text area (for example YourResult num). You could take a look at the last part of the Step-by-step Tutorial, but instead of choosing Text, choose Numeric and then the right format for you.

Sorry, Hans, this feature will need JavaScript and the generated modules don't support it. I am trying to keep the modules as simple as possible so they can be used with different Joomla installations without conflicts with other plugins.

Hi David,
the page jumps to the top because the module refreshes the whole page after submitting the data and receiving the result. Only javascript based calculators can receive data without page refresh. This module don't use javascript so you can't avoid the refresh but you could force the page to scroll down to the calculator after the refresh.
Replace this code in your_joomla_site / modules / mod_your_calculator_name / tmpl / default.php file:
htmlspecialchars(JFactory::getURI()->toString());
with:
htmlspecialchars(JFactory::getURI()->toString().'#calc');

The generated calculators don't have an option for a 'clear' button (I could add one in the next release, thank you for the idea). If you think that it is better for your users to not keep the data at all, open this file:
your_joomla_site / modules / mod_your_calculator_name / mod_your_calculator_name.php
and replace every occurence of variable definitions:
$varYourVar = isset($form["varYourVar"]) ? $form["varYourVar"] : "";
with:
$varYourVar = "";

I have no idea :) It should work as any other web content fetched through an iframe. I guess it will be a bit slow because you will have two Joomla sites to load and they are quite heavy.

Hi Andriy,
you can make almost any calculator you need for your site but it won't be an active order form. This means that your users will be able to calculate rates and totals but they have to use another module to send you (the site owner) their request and to pay the bill.

Hi Raj,
when your page is loaded your calculator is hidden by the template you are using. The user has to to click a javascript button to see it. Since this is a php calculator it needs to reload the page to display the results and after the reload the template hides the calcualtor again.
So you have to deal with this issue through javascript. For example you could modify your template to hide the calculator only if the result value is 0. Or you could try to find a javascript based calculator which won't need to reload the page in order to display the result.

Hi Jan,
yes, you can show image instead of (or next to) the option text. You just have to use HTML tags where you need a different formatting or additional elements. In you case:
1. Click to add a "Choose field"
2. Write some label and click OK
3. Write a number in the Option ID field and in the Label field write this tag:
<img width="50px" src="http://upload.wikimedia.org/wikipedia/en/thumb/7/7f/Mickey_Mouse.svg/250px-Mickey_Mouse.svg.png" />
4. Finish the calculator and test it.
If you write the URL to the image above you will see a Mickey Mouse image as one of the options. Of course you have to write the URLs to the images you want to use as options in the calculator. You can upload them anywhere in your Joomla site and then write the correct URL in the img tag.

Hi Tony,
I don't know anything about windsurfing but according to this site http://www.poolewindsurfing.co.uk/windsurfing-boards-windsurfing-sails-size/ the formula you need is:
(1.34 * Sailor Weight) / Wind
Follow these steps to build your calculator:
1. Select Number Field -> into the Label field enter "Sailor Weight (kg):" -> click OK
2. Select Number Field -> into the Label field enter "Wind (kts):" -> click OK
3. Go to the Formula panel and after "Result =" write "( 1.34 * "
-> click the "Sailor Weight" field
-> write ") / "
-> click the "Wind" field
4. Go to the bottom of the page and click "Test Calculator"
5. Test the calculator. Download it if you like it or add additional options and formatting.

Hi Tony,
X% is a mathematical expression of X/100. This means that if you need to add 10% of a value to the same value, you have to use this formula: result = value + 0.10*value
For more information you could check the Wikipedia article about percentage or a math textbook.

Dear Tony,
my advice was to check your math textbook in order to understand the way your calculator will work. If you don't feel the need for such knowledge just follow these steps:
1. Select Number Field -> into the Label field enter "Sailor Weight (kg):" -> click OK
2. Select Number Field -> into the Label field enter "Wind (kts):" -> click OK
3. Select List Field -> into the Label field enter "Skill level:" -> click OK
-> for Option ID enter 0, for Option label enter "beginner" -> click [+]
-> for Option ID enter 10, for Option label enter "intermediate" -> click [+]
-> for Option ID enter 20, for Option label enter "advanced" -> click OK
4. Go to the Formula panel and after "Result =" write ( (1.34 + 1.34 *
-> click "Skill level" field
-> write / 100 ) *
-> click the "Sailor Weight" field
-> write ) /
-> click the "Wind" field
5. Go to the bottom of the page and click "Test Calculator"
6. Test the calculator.

Thank you, Zoli for your comment and suggestions.

You could add tables and style results using some basic HTML. Just click the Edit button of the result field and add the tags you need for bold, italic, ul, table, etc.

To save and edit your module later go to the Advanced Actions and click Save Config File button. The config file is just a description of your module in text format. Save it somewhere in your computer and when you want to continue your work, come back to the site and Load it.

Hi Zoli,
I am always happy to recieve the users' feedback :)

To your questions:
1. The result field inserts a new line when it finds one. It doesn't matter if it is inside an HTML code or inside a plain text. So you have to remove all unwanted new lines from your table, like this:
<table border="1"><tr><td>Kikerülő föld mennyisége:</td> etc.

2. This is some kind of a bug, but unfortunately I can't say what causes it. May be it comes from your PHP version or configuration. The problem is that the result is stored in your module language file. The language file can't contain double quotes (") so I need to escape them with \. This works most of the time but obviously not in your case.
The easiest way to solve this issue is to replace all double quotes (") with single quotes ('), like this:
<table border='1'><tr><td>Kikerülő föld mennyisége:</td>
This will be ok with your HTML code.

3. Well, this is a feature not a bug (as some programmers joke ;) ). Examine the Unit Converter Demo and you will see that if you use the same name for a field and for a formula you can display the result inside the input field.
Because in your case you don't really want to use this feature you have to rename your formula "szegely" to something else. For example the whole formula could be:
szegelyR = szegely
Don't forget to edit your result field with the new name of your formula.

There is no problem for your comment to contain links. Quite the opposite, I very much like to see how my calcualtors are used :)

Not yet, sorry

Hi Mikael,
I know about this issue but I can't find a way to fix it, because it's in fact the right thing PHP should do.
Here is my answer to another user, which I copied for you:

The reason for the warning could be a dividing by an input field. For example: Result = 10 / numFieldX. Your PHP processor decides that numFieldX could be zero (and it is quite right because if the user doesn't fill out the field it will be evaluated as zero) and displays the warning. This won't mess with the calculations but the warning will be displayed.

- You can just turn off the warning (open php.ini file on your server and change the row "display_errors = On" to "display_errors = Off". This is the Joomla recommended value for production sites).

- If you can't edit your php.ini file, modify the calculator by creating a middle result which adds some value to the field you want to divide by. For example: Result1 = numFieldX+1

This will fool the PHP processor to think that Result1 couldn't be zero. Then edit the main formula like this: Result = 10 / Result1 and the warning will be gone. Of course, you have to be careful not to change the final result your calculator will produce.

If you can't be sure the user will always enter a value into the divisor field you have to add a conditional statement to the middle result. Otherwise PHP will display the Division by zero warning in case Result1 becomes zero.

Hi, John
No you can't link two fields, sorry.
This feature requires the use of javascript inside the generated module, which I prefer to avoid.

Thanks, Boris!
Look at the Coin Flipping Demo. The output there is formatted the similar way. You just need to add a condition to the result output (click the num / text button after the name of your result). If the condition is true your text will be displayed, otherwise the default numeric output will be displayed.

Hi Jan,
You can change any position, font, color, etc. of the calculator elements by editing the module css file:
your_joomla_site / modules / mod_your_calculator_name / tmpl / css / default.css
I am not a css expert, but I think you could use something like that to rearrange the position of your images:

#calc #jform_varRadioE>input,
#calc #jform_varRadioF>input,
#calc #jform_varRadioG>input,
#calc #jform_varRadioH>input {
     margin-top: 123px;
}
#jform_varRadioE label,
#jform_varRadioF label,
#jform_varRadioG label,
#jform_varRadioH label {
     display: inline-block;
     margin-top: 123px;
     width: 140px;
     overflow: visible;
}
#jform_varRadioE label>img,
#jform_varRadioF label>img,
#jform_varRadioG label>img,
#jform_varRadioH label>img {
     float: left;
     margin: -118px 0 0 -15px;
}

Hi Michael

all the generated calculator modules have the same structure in order to use the same css file. For example the main div element has an id = "calc". That's why you can't target your two calculators separately and to have different border. You could open your_joomla_site / modules / mod_your_calculator_name / tmpl / default.php file and add a class to the main div by replacing:
div id="calc"
with
div id="calc" class="different_calc"
Then open
your_joomla_site / modules / mod_your_calculator_name / tmpl / css / default.css file and add your specific border to the div.different_calc

If the two calculators display the same data you probably use the same field names (may be the default A, B, C notation?) When you generate the calculators you just need to give different names to the fields. For example A, B, C for the first calculator and A2, B2, C2 for the second.

Hi steve

Of course you can :) You just need to build the calculator with your desired formulas. Please check the step-by-step tutorial for a detailed explanation how to set the formulas. The demo calcuators also contain very similar examples to your request.

Hi steve
Thank you for your donation :)

I thought your request is just an example, but if you really want to calculate the number of potatoes, follow these steps:
First you need to define the calculator fields:
1. Click Number Field -> Write into the Field label textbox: "Your Weight (kg):" -> click OK
2. Click Number Field -> Write into the Field label textbox: "Your Height (m):" -> click OK
3. Click Date Field -> Write into the Field label textbox: "Your Date of Birth:" -> click OK

Then build your formulas.
The first formula will calculate how many average potatoes (1 potato = 0.375kg according to the internet) the user weights.
4. Click "Your Weight" field you created in step 1 -> The formulas textarea now contains "Result = A".
5. Click at the end of the formula (next to A) until you cursor starts to blink there. -> Write "/ 0.375" Your formula now looks like "Result = A / 0.375".

The second formula will calculate how many users have to climb on top of each other to reach the moon (the average distance to the moon is (363,104,000 + 405,696,000) / 2 = 384,400,000 according to the internet).
6. Click Add Formula. -> A second formula appears "Result1 = "
7. Click at the end of the formula (next to =) until you cursor starts to blink there. -> Write "384400000 / " The second formula now is "Result1 = 384400000 /"
8. Click "Your Height" field you created in step 2. The second formula now is: "Result1 = 384400000 / B".

The third formula will calculate the number of seconds between the user's date of birth and the current date. A single day contains 24 hours * 60 minutes * 60 seconds = 86,400 seconds.
9. Click Add Formula -> A third formula appears "Result2 = ".
10. Click at the end of the formula (next to =) until you cursor starts to blink there. -> Write " ( today - " -> Your formula now is: "Result2 = ( today - "
11. Click "Your Date of Birth" field you created in step 3. -> Now your formula is: "Result2 = ( today|date - C|date "
12. Click at the end of the formula (next to =) until you cursor starts to blink there. -> Write " ) * 86400". Your third formula now is: "Result2 = ( today|date - C|date ) / 86400"

Finally you will do some formatting to the displayed results:
13. Click the edit button of the third textarea of the generator page.
14. Delete all the text you see there.
15. Write "You weight the same as " -> click the first formula (Result) you created in steps 4-5. -> continue writing " average potato`s". Insert 1 or 2 new lines.
16. Write "If you cloned yourself and stacked your clones on top of each other, you would need " -> click the second formula (Result1) you created in steps 6-8 -> continue writing " clones to reach the moon". Insert 1 or 2 new lines.
17. Write "You are " -> click the third formula (Result2) you created in steps 9-12 -. continue writing " seconds old."
18. Click the OK button of the result formatting field.
19. Click Result|num button inside the result text. -> Click OK in the pop-up box -> Select 1,000.00 as the number format -> Click OK.
20. Do the same for the Result1|num

And you are ready! Click Test Calculator. Make some tests and click Download Module if you want to use it on your Joomla site.

I generated a config file with all the described fields and formulas. If you have trouble building the calculator yourself, just save the config file on your hard drive (This is a plain text file. Right click the link and select "Save target as..." in order to save it instead of open it in the browser). Then go to the generator and click the Advanced Actions panel (at the bottom of the screen). Click Load Config File -> Browse... -> open the config file from your hard drive and the calculator will be loaded into the generator. Then you can modify or just download the module.

Dear steve :)
You are very generous, thank you!

Unfortunately I you can't enter your data into a calculator from an excel file. If you need to add just these 3 to the calculations, it will be very easy to do so by creating 2 more formulas (I updated the config file for you to include legos and peas). If you need to add tens and thousands of such entries, please send me the excel file and I will transform it into formulas.

It is possible to display large numbers as text but the calculations are quite complicated. I made an example (you can download it here. It's a config file like the previous one, so right click the link, save it and load it into the generator). If you want to transform the numbers from your original calculator you would need to copy this set of formulas several times which is not very elegant solution. It will be better if I unite the two calculators into one module directly inside the php files. If you want this, please send me your calculator when you are ready and I will add the number-to-text transformation manually.

According to the internet, a volume of a human body is =weight/1000. If we take the Wembley Stadium which has volume of 4 000 000 cubic meters, we just need to divide 4 000 000 / (user's weight / 1000). I added this formula to your config file as well.

Hi Richard
Thank you for the kind words.

The dot on your site comes from your base template css (plugins / system / jat3 / jat3 / base-themes / default / css / template.css) which defines a bullet to all list elements inside a column:
.column ul li {background: url("../images/bullet.gif") }

To fix this you have to modify this css file or the css file of your calculator.
For example, you could add to the your_joomla_site / modules / mod_your_calculator_name / tmpl / css / default.css file this code:
#calc-varNumA { background: none;}

Hi Mirco,

I see you are trying to solve your issue right now (the site behaves different every time I open it :).

I don't find anything unusual in your module, except that you use very long names. I would suggest to generate the calculator again but with shorter name. If this doesn't work try to shorten the names of the variables too. If this also doesn't work try temporarily turning off the other form you have in the right column.

If nothing works please write me again and I will think of other possible sollutions.

Hi Mirco,

I think the problem is in the server/PHP configuration. Your $_POST array is always empty.

I've never had such a problem, so I googled for a similar case and found this:
http://stackoverflow.com/questions/1282909/php-post-array-empty-upon-form-submission
http://www.od2dev.be/empty-post-array-issue/

Do you have access to your .htaccess file (if your server is Apache) or web.config (in case it's IIS)? Is it redirecting one address to another?

I doubt it will help, but you could try to open your_joomla_site / modules / mod_your_calculator_name / tmpl / default.php file and replace:
<form action="<?php echo htmlspecialchars(JFactory::getURI()->toString()); ?>" method="post"
with
<form action="" method="post"

I am sorry I am not of much help here. May be you should ask for assistance your hosting provider or someone with a full access to your server and the backend of your site.

The $_POST array is where the submited data is stored. First the user loads the php page with the calculator form, fills it out and clicks the submit button. The data s/he entered is stored in this POST array and when the page is loaded again it reads the data and calculates the result. This happens in the site backend through php script.

Although I can't test it (because I don't have access to the backend of your site) I think the $_POST array is empty and not storing the data because in the module default.php file there is an if statement:
if (isset($_POST['submit_rechner'])) and in your case this condition is never true (if it was, the result will be visible, even if it's just zero)

Also in the module main php file there are similar statements which check the previously entered data. For example if the user's inputs were stored into the POST array the entered values would be filled in the appropriate input boxes when the calculator loads again.

Because of these two, I am sure that your POST array is empty. Unfortunately I can't say why...

Hi Goldmark,

Thank you for your suggestion. I am trying to help all my users but can't dedicate myself to this project because of some family engagements. That's why I prefer not to set a fixed fee, but I will appreciate any donation the user could send for my assistance.

If you have a specific calculator in mind, please send me a description to my mail (jcg at andrewart.net) and I will return you the formula or a payment request if your calculator is too complicated.

Hi, Максим

I tested the calculator on your site and it works ok now. Can you describe the problem again? You can write in Russian if you like. I will understand, although I will answer in English (my Russian is very rusty :)

Hi Rob and thank you.
You can format the result (or the field labels) with HTML tags. Just click the Edit button of the result field and add the tags you need for bold, italic, ul, table, etc.

You could also modify the whole appearance of your module by editting your_joomla_site / modules / mod_your_calculator_name / tmpl / css / default.css file

I can't see where are your table tags, but I guess you have the same problem as Zoli (check the comments from 04 Feb 2013). Here is the solution:
"The result field inserts a new line when it finds one. It doesn't matter if it is inside an HTML code or inside a plain text. So you have to remove all unwanted new lines from your table, like this:
<table border="1"><tr><td>Kikerülő föld mennyisége:</td> etc.

Thank you Rob, for the kind words and for the donation.
I am glad you like my calculator generator :)

Hi Rob :)
It could be some css conflict (may be your site template is overriding the calculator css). Can you give me the link to your homepage to examine it?

Hi Rob,
your template css (businesspapass4) adds a span wrapper around all the buttons on the page. It moves the calcualtor button to the left and behind the left column. I suggest you to add these styles to your calculators your_joomla_site / modules / mod_your_calculator_name / tmpl / css / default.css file:
#calc>form>span.art-button-wrapper {
     position: static;
     display: inline;
     height: auto;
     width: auto;
     overflow: auto;
     z-index: auto;
}
#calc>form>span.art-button-wrapper>span {
     display: none;
}

Try this and tell me if it works.

Did you make the change on your site? Because I still see the "position:relative" style on the span element here: http://www.business-papas.at/index.php/online-rechner-fuer-steuer/online-rechner-fuer-steuer
You need to open (or download) the calculator "default.css" file (http://www.business-papas.at/modules/mod_calc1357/tmpl/css/default.css), paste these styles and save (upload the file to the server again)

Hi Rob! Sorry for the delay.
Yes, you can change your site template the same way you changed the calculator template. I wouldn't recommend it though, because you could mess with the formatting of other buttons on the page and also it will make the update of the template very difficult.

Please, open the calculator "default.css" file (http://www.business-papas.at/modules/mod_calc1357/tmpl/css/default.css) again and replace these styles:
#calc-button {
     color: #900;
     border: none;
     border-radius: 9px; -moz-border-radius: 9px; -webkit-border-radius: 9px;
     background: #ddd;
     cursor: pointer;
     font-weight: bold;
     font-size: 1.2em;
     text-align: center;
     margin: 1em;
     padding: 0.5em;
     position: absolute;
     bottom: -2em;
     right: 1em;
     height: auto;
}
with:
#calc-button {
     color: #900 !important;
     border: none;
     border-radius: 9px; -moz-border-radius: 9px; -webkit-border-radius: 9px;
     background: #ddd;
     cursor: pointer;
     font-weight: bold;
     font-size: 1.2em;
     text-align: center;
     margin: 1em !important;
     padding: 0.5em !important;
     position: absolute;
     bottom: -2em;
     right: 1em;
     height: auto;
     top: auto;
     line-height: inherit;
     font-family: Arial, Helvetica, sans-serif;
}

This way we are overriding some of the wrapper formatting. It's not a good practice to use the keyword "important!" but since the site template is using it, we have no other choice.

P.S. About your request to add this modifications to all the calculators generated by my site: I can't do that, because most of the other users have other Joomla templates and this will be unacceptable for them. But you could make one default.css file for all your calculators and after installing a new calculator module to the site, just replace its original css file with yours.

I am glad it's finally ok now.

The easiest way to keep this design every time you load a new version is:
1/ To save the modified default.css file on your hard drive.
2/ When install a new module (or update an old one) upload the saved file to the server in this folder:
your_joomla_site / modules / mod_your_calculator_name / tmpl / css /
to replace the default file.

BTW why don't you try another template for your site ;) This one is very aggressive and could mess with other modules in the future.

The link is great, thank you!
I am very glad you find the generator useful and that you managed to create such a complicated calculator.

Oh, you don't like my default design? ;)
You can change almost anything by modifying your_joomla_site / modules / mod_your_calculator_name / tmpl / css / default.css file

I don't know what exactly you want to change.
For example you could add
#calc { font-family: verdana, tahoma, helvetica, sans-serif } to set the same font as the example you like.
Or remove the #calc-button {...} styles to use the default browser button as the example does (Although, because of your template, this won't be enough. You have to edit the button styles of your template too)

How about this:
add these lines at the end of your default.css file:
#calc {
     max-width: 650px;
}
#calc .inputbox, #calc .calc-input>select {
     margin: 0.5em;
     margin-right: 0;
     float: left;
}
#calc .calc-input>label {
     display: block;
     float: left;
     max-width: 500px;
     padding: 0.5em 0;
     text-align: right;
}

Oops, sorry. I found an error. Please, try this code instead:
#calc {
     width: 650px;
}
#calc .calc-input {
     clear: both;
}
#calc .inputbox, #calc .calc-input>select {
     margin: 0.5em;
     margin-right: 0;
     float: left;
}
#calc .calc-input>label {
     display: block;
     float: left;
     width: 500px;
     padding: 0.5em 0;
     text-align: right;
}

Hi Bianca,
if I understend correctly you just want your calculator to add 1001 days to the input date. This is very simple:
1/ Create the input date field
2/ Click on it -> the input field appears into the Formula textbox
3/ Write next to it +1001
4/ And you are ready! Click Test Calculator and test.

I don't know why are you comparing the date against 1001 (if A is >1001)... This way you are adding 1001 to the date only if the date is bigger than 1001 which is also ok (unless the user enters a date before the year 1602 ;) ) but it's unnecessary.

Your formula should be just: Result = A|date + 1001

Hi vanman,
to use the power function:
1/ select "power" from the Math menu in the right corner. A small table appears.
2/ Delete 0 from the left box and write: 1+ then click the "rate" field/result
3/ Delete 2 from the right box and click "years" field/result

The modules are tested and work in Joomla 1.6 - 3.0. To install a module follow the standard steps:
1/ Upload the zip through Extension Manager
2/ Open the installed module in Module Manager
3/ Select a visible position of your site template; select published status; select specific pages or "On all pages" from Module Assignment
4/ Save the changes

Hi Rob,
there is no special way to print the generator's interface. Can you just use to the Print button of your browser? I tried it with Firefox 15 and Internet Explorer 10. They both seems to render the formulas correctly (may be IE10 is better, because Firefox sometimes cuts parts of the long formulas).

You could try to disable CSS and then print the page. It will be quite ugly but nothing will be cut off...

Hi Ian,
I don't know much about loans either, but I found this site on the Internet
It explains the formulas for payment, loan amount and term. I don't know what exactly are you trying to calculate, but if you want to use the formula from the example, you have to:
1/ create 3 input fields for your calculator (loan amount, interest rate, months)
2/ create a formula to get the periodic rate: interest rate / 12 / 100
3/ create a formula to get the payment amount (monthly): loan amount * (periodic rate / (1 -
select the power function from the Math tab in the upper right corner and the table will appear. Write into the left box:
(1/ (1+periodic rate))
and into the right box click the months field:
months
finish your formula with:
))

The second formula gives you the monthly payment. If you need the total payment (for the whole loan period) you need to multiply the monthly payment by the number of months. If you need something else... well you have to decide what is it :)

To add one formula in the calculation of another just click anywhere over the first formula while the second is in edit state.
Did you read the Step-by-step Tutorial? There you will find screenshots and more detailed explanations of all the actions you need to execute to generate a calculator.

It depends on the formulas :) If it's possible to generate the calculator without editing the module code (which means: no loops, no special design) I can make it for free (of course I am always glad to recieve a small donation from my happy users :)

Dear users,

I am expecting my first child next week! After her birth I won't be able to respond so quickly to your questions and I apologize in advance. Please, continue to post your comments and I will try to read them at least once a week.

Thank you, Ian :)

I checked your last test. You are missing two open brackets.
A * ( Periodicrate / ( 1 - power table [ ( 1 / ( 1 + Periodicrate ) ) | C ] ) )
The second is not mandatory, but since you are closing the brackets you need to open them first ;)

I am not in the UK :)
(I didn't think my English is so good to fool anyone I live in an English speaking country :))) Thank you!)

And no, I don't save all users attempts, only those made in the last hour. This way, if the user leaves the site and comes back a little later, he won't lose his work. And since we are talking in real time I was able to check your last attempt.

Thank you for the recommendations! They are very helpful.
Don't give up! Your previous attempt was ok, you just had to add these 2 open brackets (I can't see your last attempt and can't tell what's wrong with it, sorry)

I made a config file for you. You can compare your attempts with it and see what you are doing wrong.
To use the config file:
1/ download it from here (right click the link and select Save as... to your computer)
2/ open the generator, scroll and open Advanced Actions
3/ load the config file from your computer to the generator
4/ examine the formulas, edit them if you need, test the calculator, download the module if you like it

Well, you could write a conditional statement like this:
result3 :
     if (result1 > result2)
          + result1
     else
          + result2

On 16 April 2013 my daughter Assia was born! She is at home now and we are trying to build the formulas for changing diapers, breastfeeding and bathing :)

Hi guys and thank you! Sleeping has a very difficult formula and I am still trying to invent it :)

It will be great if you can help each other!
I am checking my mail every day but don't have much time for anything else. Don't hesitate to ask questions, though. I will try to answer as soon as possible.

Sorry, FromHeLL
This feature is not available yet.

No, you can't. The generator creates only Joomla 1.6+ modules.
Sorry!
