Null querys?

If i run a query, to select all the forums that a user moderates, how can i check to see if the result is nothing?

PHP Code:


		
			
if ($access=="") { echo "no access"; die; }

??

Would that work?

How would i do it if not?

  echo "no access"; 

  die;

No, that won't work.

Code:

$access = $DB_site->query_first("Your query here");

if (!$access) {

  echo 'No access';

  exit;

}

Queries never return an empty string.

Like that matters :) - I normally do use the layed out format, but when typing i dont bother formatting my code.

FireFly : Thanks :)
