A few tips for you:

• DO NOT confuse $_POST with $_SESSION
• DO NOT use mysql use mysqli or for extra protection against sql injection, use PDO . Here a useful link to learn about it http://wiki.hashphp.org/PDO_Tutorial_for_MySQL_Developers
• If it is a shopping cart demo you are trying to code, do not use the price amount submitted in a form. Always validate it against a value stored on the database.

Good Luck and read as much as you can.
