Max,

I'm trying to do the server side validation for an email. I'm using the following code in the server side validation code box but it doesn't seem to work.

<?php
$ref_num = JRequest::getVar('text_4', '', 'post');

$db =& JFactory::getDBO();
$query = "
SELECT count(*)
FROM `#__users`
WHERE `ref_num` = ".$db->Quote($quote)." ;
";
$db->setQuery($query);
$in_use = $db->loadResult();
if ( $in_use) {
return "That email is already registered, please try again";
}
?>

Hi spelcher,

A bit late for me but I think that

WHERE `ref_num` = ".$db->Quote($quote)." ;

should be

WHERE `ref_num` = ".$db->Quote($ref_num)." ;

as $quote isn't defined here.

thanks. I've changed that but no success yet.

I got this code from one of Max's posts on preventing duplication of table entries.

Hi spletcher,

The second problem is that there isn't a field called ref_num in jos_users, the email field is `email` so the code needs to be

<?php
$email = JRequest::getVar('text_4', '', 'post');

$db =& JFactory::getDBO();
$query = "
  SELECT count(*)
    FROM `#__users`
    WHERE `email` = ".$db->Quote($email)." ;
";
$db->setQuery($query);
if ( $db->loadResult()) {
  return "That email is already registered, please try again";
}
?>

Awesome - that fixed it.

Whoops - I should have seen that one!!
