The main problem is that you've never explained what you want to get
from the query. The replies have used your code as an example and I'm
pretty sure that's not what you want. Unless I totally mis-understand
what you want, you have 2 options:
1. Use the 2 queries that I gave you in a previous post.
2. Use a subquery:
$sql = "SELECT * FROM workorders WHERE AdminID = (SELECT AdminID FROM admin WHERE UserName = '" . mysql_real_escape_string($_SESSION['user']) . "')";
