I am currently learning php and I am using Practical PHP and MySQL® Building Eight Dynamic Web Applications by Jono Bacon I know this is not the best book to learn from but it is what I was given. My current problem is that when logged in and have items in the shopping cart, I go to the check out and can not go any further. I don't get any errors it just does nothing but show an address form that just clears if you add an address [attachment deleted by admin]

Please any help with this problem will be greatly appreciated Where and how would I do that?

Warning: mysql_num_rows() expects parameter 1 to be resource, boolean given in C:\xampp\htdocs\sas\shoppingcart\adminlogin.php on line 16 Warning: Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\sas\shoppingcart\adminlogin.php:16) in C:\xampp\htdocs\sas\shoppingcart\adminlogin.php on line 33 [attachment deleted by admin]
