I have one table which contains user_id, username, password and points columns. It is in table named "users" in database named 'admin_users".

When one successfully login, the following is set...
PHP Code:
$username $_SESSION['username']; 
now, i want to store $points variable equal to points of user named "$username" , how to do it. Means (i think i wasn't clear what i wanted to say), i want to get value of column "points" from table users where username = $username....

I am totally confused, hope you help.
