Hi guys,

I have a form that has a long list of radio-bottons inside of it. The
radio-buttons are dynamically created via php and MySQL.

Here is an example of one of the radio buttons:

<input type="radio" name="<?php print ("radio_".$result_from_mysql) ; ?>" 
value="0">
<input type="radio" name="<?php print ("radio_".$result_from_mysql) ; ?>" 
value="1">

Now, when I submit this form to another page for processing, how would I "catch"
the above radio-button's $_POST name since I do not know the name, only that it
starts with "radio_" ?

foreach ($_POST as $k => $v) {
    if (substr($k,0,6) == 'radio_') {
        echo 'Name is -> ',$k,'<br />';
        // Do stuff...
    }
}

HTH
Rich
