I've got a premade Regular expression function that seems to not be picking up the reg expression correctly. The previous programmer couldn't get it working and neither could I.

function RegExp($name, $re, $error)
	{
			// Client
		$this->AddJS("
		re = $re;
		if(!re.test(form.$name.value)) {
			alert('$error');
			form.$name.focus();
			return false;	
		}

		");
		
			// Server
		if(preg_match($re, $_REQUEST["$name"]) == 0) {
			$this->errors[] = $error;
			return false;
		} else {
			return true;
		}
	}

RegExp('VISIT','/([0-9]{2})\/([0-9]{2})\/([0-9]{4})/', 'Please, enter correct requested ship date.');

Which part isn't working. When boiled down to this, it seems to work just fine:

function RegExp($testValue, $re)
{
        if(preg_match($re, $testValue) == 0) {
            return 'fail';
        } else {
            return 'pass';
        }
        
}
    
echo '---'.RegExp('10/23/2010','/([0-9]{2})\/([0-9]{2})\/([0-9]{4})/').'<br>';
echo '---'.RegExp('10/230/2012','/([0-9]{2})\/([0-9]{2})\/([0-9]{4})/').'<br>';

the client side will not pop up with the error. Will try yours monday and see how it goes.

Server side php works good.
