[Done 2.0.0] /includes/classes/shopping_cart.php

I am not sure if this is a bug or not but the error below is filling up our error log like crazy. Our db was recently upgraded to MYSQL 5.0+ so I am not sure if this related.

PHP Warning: Variable passed to each() is not an array or object in /var/www/html/includes/classes/shopping_cart.php on line 1708

Line 1708 reads: ```php
while ( list( $key, $val ) = each($_POST['products_id']) ) {

What version of PHP is installed and what version of Zen Cart are you using?

What version of PHP is installed and what version of Zen Cart are you using?

Zen Cart 1.3.7
PHP Version: 5.2.0 (Zend: 2.2.0)
Database: MySQL 5.0.27-standard

its definitley nt anything to do with mysql 5.

I have a vague suspicion that its something to do with spiders, but will play around with it to see if I can reproduce

Thanks!

HI,

I'm still convinced this is caused by a spider picking up on a posted url.

Code has been committed to bug fix branch to try and address the problem.

If you want to try and adjust your current code then you need to replace your current

function actionMultipleAddProduct
with

  function actionMultipleAddProduct($goto, $parameters) {
    global $messageStack;
    if (is_array($_POST['products_id']) && sizeof($_POST['products_id']) > 0) {
      while ( list( $key, $val ) = each($_POST['products_id']) ) {
        if ($val > 0) {
          $adjust_max = false;
          $prodId = $key;
          $qty = $val;
          $add_max = zen_get_products_quantity_order_max($prodId);
          $cart_qty = $this->in_cart_mixed($prodId);
//        $new_qty = $qty;
//echo 'I SEE actionMultipleAddProduct: ' . $prodId . '<br>';
          $new_qty = $this->adjust_quantity($qty, $prodId, 'shopping_cart');

          if (($add_max == 1 and $cart_qty == 1)) {
            // do not add
            $adjust_max= 'true';
          } else {
            // adjust quantity if needed
            if (($new_qty + $cart_qty > $add_max) and $add_max != 0) {
              $adjust_max= 'true';
              $new_qty = $add_max - $cart_qty;
            }
            $this->add_cart($prodId, $this->get_quantity($prodId)+($new_qty));
          }
          if ($adjust_max == 'true') {
//            $messageStack->add_session('shopping_cart', ERROR_MAXIMUM_QTY . ' C: - ' . zen_get_products_name($prodId), 'caution');
            $messageStack->add_session('shopping_cart', ERROR_MAXIMUM_QTY . zen_get_products_name($prodId), 'caution');
          }
        }
      }
// display message if all is good and not on shopping_cart page
      if (DISPLAY_CART == 'false' && $_GET['main_page'] != FILENAME_SHOPPING_CART) {
        $messageStack->add_session('header', SUCCESS_ADDED_TO_CART_PRODUCTS, 'success');
      }
      zen_redirect(zen_href_link($goto, zen_get_all_get_params($parameters)));
    }
  }

Always ensure you back up files you are changing !!

Applying the code above seem to have solved the problem.

Thanks for the confirmation.
We'll use this or some rendition of it to prevent spiders from triggering unwanted alerts.
