Hey guys,

I have reached my wits end with this..! This code works on two of the servers that I have tested, but doesn't want to work on the third server that I need it on! It displays fine, but when the form data is posted back itself to be validated, I get a blank page - No error messages or clues as to what may be causing the problem.

<?php //session_start();



//THIS FUNCTION VALIDATES ALL USER INPUT

function VerifyForm(&$values, &$error) {



   if (strlen($values['title']) == 0) {

		$error['title'] = 'Please specify your title';

   }

Any ideas why this wouldn't work?
Thanks

I have found the problem...

It was with with this validation regular expression for telephone number:

if (!filter_var($values['telephone'], FILTER_VALIDATE_REGEXP, array('options' => array('regexp' => "/^0[1-9][0-9]{8,9}$/")))) {  

		$error['telephone'] = 'Invalid number';

   }

Thanks anyway
