This will work:

HAVING admin.username='".$_SESSION['user']."'
";

Don't use having in this case - this should be a 'where' clause.

A 'having' clause is processed AFTER everything else (after where, after joins, after aggregate's are calculated like sum/max/min), using it like this will cause performance issues where you shouldn't have any.
