Problems with custom query and registration

[Jolten]

Hi,

I run a custom query on my site. It looks like this:

$creditinfo = $DB_site->query_first("SELECT curcredit FROM usrcredit WHERE usrname='$bbuserinfo[username]'");
$credit = $creditinfo[curcredit];

This query works wonderfulling in 99.9% of cases. But I do have a problem with it at registration.

If a user tries to register with a ' in their username the query errors due to the '.

I do have all odd characters including the ' excluded in the vb registration options. If my custom query is not added anywhere in any fine the registrtion will kickback and tell the user that the ' is unacceptable. But if my query is included in any file the query errors at registration, and registration only.

I've added my query to global.php and even to the php_onclude_start template. it works fine in both those places, except for registration.

So here's my question... how can I tell the query to not execute if the registration name contains bad characters?


Thanks.
