Form Checkbox Total.... Total Beginner needs help!

[JohnnyBighead]

Hello all, thanks for everything you do!

 

I used a php from generator to make the form seen on this page:

http://www.firstpresgreenville.org/forms/retirementform/retirementform-alt.html

 

I need to be able to click on the check boxes and get a dollar amount total in the total field....So if you checked "single", the total field would read $40, and if you checked on "couple", the field would read $50...simple as that...

 

Is there anyway to make that happen? 

 

This is the code I am working with now....

 

<?php

 

# This block must be placed at the very top of page.

# --------------------------------------------------

require_once( dirname(__FILE__).'/form.lib.php' );

phpfmg_display_form();

# --------------------------------------------------

 

 

 

function phpfmg_form( $sErr = false ){

        $style=" class='form_text' ";

 

?>

 

<form name="frmFormMail" action='' method='post' enctype='multipart/form-data' onsubmit='return fmgHandler.onsubmit();'>

Thanks so much!

My guess would be that you want it to show the total without a page reload... you would need to look into javascript to do that as PHP is a server side language and requires a server call to make page changes.

Since your checkbox coding is not in the above code, I'll write it out.

 

<html>
<head>
<script type="text/javascript">
function addCheck() {
var s = document.getElementById('single');
var d = document.getElementById('double');
var t = document.getElementById('total');
if(s.checked == true) {
  t.value = 40;
}
if(d.checked == true) {
  t.value = 50;
}
}
</script>
</head>
<body>
<form>
<input type="radio" value="40" id="single" name="persons" onclick="addCheck();" /><label for="single"> Single</label><br />
<input type="radio" value="50" id="double" name="persons" onclick="addCheck();" /><label for="single"> Double</label><br />
<input type="text" value=0 id="total" name="total" /><label for="total"> Total</label>
</form></body>
</html>

 

This is only an example, load it up in your browser and see how it works.
