that admin_login.php page, , inside db_connection.php code connect users database

i have tried putting session variables above echo welcome.php, not worked.

in case still confused, $_session['adminname']=$admin_name; , $_session['isadmin']='true'; not setting correctly, , have no clue why.

you have call function

session_start();

somewhere before using $_sessionglobals. here's documentation it!
