Hello,

I am trying to update my PHP CART without having the page refreshed!
I don't know how to do it because just now I got JS/AJAX/JQuery to play with.

So any help will be appriciated.
(I already tried some scripts but.... )

Here is a part of my code... I will just use the UPDATE_QUANTITY part (there are ADD & Remove)

My form that holds the quantity:
Code:
<form name="upd_itm" id="upd_itm" action="cart_function.php" method="post">
<span class="text"><input name="quantity" type="text" value="' . $each_item['quantity'] . '" size="1" maxlength="2" style="text-align: center;"/>
<br />
<button name="adjustBtn' . $item_id . '" id="adjustBtn' . $item_id . '" type="submit" class="avoid_ref" value=""><img src="bttn_pics/change_value.png" /></button>
<input name="item_to_adjust" id="item_to_adjust" type="hidden" value="' . $item_id . '" /></span>
</form>
My action.php that proccess it:
Code:
if (isset($_POST['item_to_adjust']) && $_POST['item_to_adjust'] != "") {
    // execute some code	$item_to_adjust = $_POST['item_to_adjust'];	$quantity = $_POST['quantity'];
	$quantity = preg_replace('#[^0-9]#i', '', $quantity);
 // filter everything but numbers
      if ($quantity >= 100) { $quantity = 99; }
      if ($quantity < 1) { $quantity = 1; }
      if ($quantity == "") { $quantity = 1; }
        $i = 0;
         foreach ($_SESSION["cart_array"] as $each_item) {
 	$i++;
	while (list($key, $value) = each($each_item)) {
	  if ($key == "item_id" && $value == $item_to_adjust) {	
	  // That item is in cart already so let's adjust its quantity using array_splice()
	  array_splice($_SESSION["cart_array"], $i-1, 1, array(array("item_id" => $item_to_adjust, "quantity" => $quantity)));
	  } // close if condition
      } // close while loop
} // close foreach loop}
Thank you in advance
