Posts ($_POST) is used to take information from a form to the next screen (passing it along). You name the feild and then that becomes the name you will call back. For example:
The Name there is quantiy. Therefore when the feild is carried over you can call back the variable using:
$quantity = $_POST['quantity'];
?>
Ensure you use '' ( $_POST['quantity'] ) for statements and either use (int) or take them out for numbers:
Statment
$quantity = $_POST['quantity'];
?>
Number
$quantity = $_POST[quantity];
?>
Also a Number
$quantity = (int)$_POST['quantity'];
?>
