$id = $_GET['id'];

if(isset($_GET['action'])){
$action = $_GET['action'];
}else echo $action="Empty Cart" ;

switch($action){
               case 'add':
		   if(isset($_SESSION['cart'][$id])){
		        $_SESSION['cart'][$id]++;}
		   else $_SESSION['cart'] =1;
		   break;
		   
		   case 'remove':
		   if(isset($_SESSION['cart'][$id])){
		   $_SESSION['cart'][$id]--;
		   if($_SESSION['cart'][$id]==0){
			   unset($_SESSION['cart'][$id]);
			   }
		   }
		   break;
		   
		   case 'delete':
		   unset($_SESSION['cart'][$id]);
		   break;
		   }}

////////////////////////////// Display Shopping Cart /////////////////////////////////
               if(isset($_SESSION['cart'])){
			       $total = 0;
			   foreach($_SESSION['cart'] as $id => $value){
			   }
				   $result = mysql_query("SELECT * FROM products WHERE id=" . $id)or dei(mysql_error());
				   $row = mysql_fetch_array($result);
			       $price = $row['price'];
				   $line_cost = $price * $value;
				   $total = $total+ $line_cost;
				   
			   }print_r($_SESSION['cart']);

So you understand why your foreach loop was failing then?

 

foreach( 1 as $id => $value )

 

You need to make sure $_SESSION['cart'] is an array before looping through it.

 

 case 'add':
		   if(isset($_SESSION['cart'][$id])){
		        $_SESSION['cart'][$id]++;}
		   else $_SESSION['cart'] =1;
		   break;

is probably the issue.

 

jesi beat me to it.

$_SESSION['cart'] is still 1. 1 is an integer, and can not be looped through using foreach.

 

We've told you where the issue is, it's up to you to ask the right questions, or fix it.

Okay so see how cart = 1? That's not an array. An array would be like

[cart] => Array ( [qty] => 1 [id] => 7)

 

We already told you where the problem is, and another person even posted the section of code that is the problem.
