[support] Passing multiple values into a single Views argument

[Ursula Pieper]

Neil,

If you use return inside the while loop like you do it, the loop will
process the first return of the query (37), and return that value to
the parent function. It basically will break the loop and won't go
through it until the further entries are processed.

You need to concatenate the fetched values to a variable (for
example), and return that variable once the loop is finished.
while($member = db_fetch_object($result)){
    $variable.= $member->uid . "+";
}
return $variable;

If you want to retrieve the values from the database ordered, you need
to add an "order by node.uid asc" to the SQL query.

Hope this helps, Ursula
