Harayoon - would this work?

$crit = new Criteria('id', 1, '<>'); // Should get all groups except for admin
$hGroups =& xoops_gethandler('group'); // Make groups handler
$groups =& $hGroups->getObjects($crit); // Retrieve groups matching criteria

echo "<select name='groups'>"; // In your registration form
foreach($groups as $group){ // Loop through each group
echo "<option value='".$group->getVar('id')."'>".$group->getVar('name')."</option>";
}

I guess I should add a comment to my previous post - that snippet I posted would create a drop down list of all possible groups to choose from, as opposed to the radio selects you're using here. Useful if you have more than one group to choose from upon registration. This is theoretical, someone posted it in response to one of my earlier questions on this topic, but I've yet to try it out myself.

the hack turns out an error message, something like "usericq should not be more than 15 characters long" even after changing value of field via phpmyadmin.

what should be done?
