removing one cart item also deletes another

[ttoomey]

I'm try to make it so that when a user selects one item in the shopping cart for removal and clicks the update button, another item will also be deleted. I narrowed the code down to this part of application_top.php:

 

  case 'update_product' : for ($i=0, $n=sizeof($HTTP_POST_VARS['products_id']); $i<$n; $i++) {
                               if (in_array($HTTP_POST_VARS['products_id'][$i], (is_array($HTTP_POST_VARS['cart_delete']) ? $HTTP_POST_VARS['cart_delete'] : array()))) {
         $cart->remove($HTTP_POST_VARS['products_id'][$i]);
                               } else {
                                 if (PHP_VERSION < 4) {
                                   // if PHP3, make correction for lack of multidimensional array.
                                   reset($HTTP_POST_VARS);
                                   while (list($key, $value) = each($HTTP_POST_VARS)) {
                                     if (is_array($value)) {
                                       while (list($key2, $value2) = each($value)) {
                                     if (ereg ("(.*)\]\[(.*)", $key2, $var)) {
                                           $id2[$var[1]][$var[2]] = $value2;
                                         }
                                       }
                                     }
                                   }
                                   $attributes = ($id2[$HTTP_POST_VARS['products_id'][$i]]) ? $id2[$HTTP_POST_VARS['products_id'][$i]] : '';
                                 } else {
                                   $attributes = ($HTTP_POST_VARS['id'][$HTTP_POST_VARS['products_id'][$i]]) ? $HTTP_POST_VARS['id'][$HTTP_POST_VARS['products_id'][$i]] : '';
                                 }
                                 $cart->add_cart($HTTP_POST_VARS['products_id'][$i], $HTTP_POST_VARS['cart_quantity'][$i], $attributes, false);
                               }
                             }
                             tep_redirect(tep_href_link($goto, tep_get_all_get_params($parameters)));
                             break;

 

I added this code

 

                                  if (($HTTP_POST_VARS['products_id']['150']) && (is_array($HTTP_POST_VARS['cart_delete']) ? $HTTP_POST_VARS['cart_delete'] : array())) {
         $cart->remove($HTTP_POST_VARS['products_id']['165']);
         }

 

just above the cart->remove line, yet it doesn't delete the other product it only deletes the selected product. Is there another way to make multiple products delete from the shopping_cart.php by just clicking on one of the remove checkboxes?

Does anyone know of a way to do this so that by checking one product in the cart will delete another?
