value set to null on evaluation

Hi there,

I am experiencing difficulty with my on submit before email processing. The problem is that when I evaluate a user entered value to determine if it is the same as a preset hidden value, the user entered value is ending up null after submission. Here is the block of code:

<?php
global $mainframe;

if ( JRequest::getVar('enteredcode_CP1') == JRequest::getVar('hidden_code_CP1') ) {
    $cp1value = JRequest::getVar('hidden_value_CP1');
    JRequest::setVar('hidden_earned_points_CP1',$cp1value); 
} 
?>

For example if the user enters "AA" for 'enteredcode_CP1', this correctly results in 'hidden_earned_points_CP1' being set to the value of 'hidden_value_CP1', however at the same time instead of getting "AA" in the DB record that is saved, the 'enteredcode_CP1' is null. I don't understand why this is happening - I only get this value, I don't set it, so why is it changing from what the user has entered??

Thanks for your assistance.

Hi markoadams,

Generally using JRequest in an 'if' statement gives a PHP error, this may be happening 'invisibly' with your code. Please try this slightly longer version:

<?php
$enteredcode  = JRequest::getString('enteredcode_CP1', '', 'post');
$hidden_code  = JRequest::getString('hidden_code_CP1', '', 'post');
$hidden_value = JRequest::getString('hidden_value_CP1', '', 'post');

if ( $enteredcode == $hidden_code ) {
    JRequest::setVar('hidden_earned_points_CP1', $hidden_value);
}
?>
