DB_DataObject

Hello,

I am doing a registration system using DataObject and HTML_QuickForm.

It's a bit strange, but all of the sudden, my custom rule stopped
working.

To be precise, the DataObject inside throws out a message:
DB_DataObject Error: No database name / dsn found anywhere

Offending script:

function username_exists($element_name, $element_value) {
$check_username = new DataObject_Protocols_users;
$check_username->username=$element_value;
$num_results = $check_username->find();

if ($num_results == 0) {
return true;
}
else {
return false;
}

}

It works just fine once I take the script out of function....

So, what is it, I am missing here?
