Hi guys, this codes works perfectly to me, except that i would like to add pricetotal in session variable. my problem is pricetotal does not display values when i use print_r.

Heres the output when i use print_r to display session variable:
Array ( [0] => Array ( [item_id] => 15 [quantity] => 56 [pricetotal] => ) )

It should be like this:
Array ( [0] => Array ( [item_id] => 15 [quantity] => 56 [pricetotal] => 5500) )

please help me to fix my problem: thanks

the code use:

    <?php 

    //Section 1 (if user attempts to add something to the cart from the product page)
    if (isset($_POST['pid'])) {
        $pid = $_POST['pid'];
        $wasFound = false;
        $i = 0;
        // If the cart session variable is not set or cart array is empty
        if (!isset($_SESSION["cart_array"]) || count($_SESSION["cart_array"]) < 1) { 
            // RUN IF THE CART IS EMPTY OR NOT SET
            $_SESSION["cart_array"] = array(0 => array("item_id" => $pid, "quantity" => 1,"pricetotal" => $pricetotal)); 
        } else {
            // RUN IF THE CART HAS AT LEAST ONE ITEM IN IT
            foreach ($_SESSION["cart_array"] as $each_item) { 
                  $i++;
                  while (list($key, $value) = each($each_item)) {
                      if ($key == "item_id" && $value == $pid) {
                          // That item is in cart already so let's adjust its quantity using array_splice()
                          array_splice($_SESSION["cart_array"], $i-1, 1, 
                          array(array("item_id" => $pid, "quantity" => $each_item['quantity'] + 1,"pricetotal" => $pricetotal))); 
                          $wasFound = true;                   
                      } // close if condition
                  } // close while loop

               if ($wasFound == false) {
                   array_push($_SESSION["cart_array"], array("item_id" => $pid, "quantity" => 1, "pricetotal" => $pricetotal));
               }
        }

        redirect_to("cart.php"); 
        exit();

Hi guys, this codes works perfectly to me, except that i would like to add pricetotal in session variable. my problem is pricetotal does not display values when i use print_r.

You mention it works but the issue you are having is the pricetotal appearing?

So another words it doesn't work.

If it doesn't work I would look at on line 99 which is this line:

$pricetotal = $price * $each_item['quantity'];

I'm also not sure why you comment line 120:

//$cartOutput .= '<td>' . $each_item['quantity'] . '</td>';

You are trying to assign $pricetotal to the $_SESSION["cart_array"] array several times on the beginning but $pricetotal variable is not existing yet at that point. It is getting created on line 99. Maybe you should assign it to a hidden input if you want to use it after POSTing the form.
