# Help finding syntax error

 * I was advised by theme developer to add this snippet to my theme’s function.php
   file to modify cart behavior. When I did I received a fatal error message due
   to a syntax error. Can someone please tell me what that error is:
 *     ```
       add_filter( \'woocommerce_return_to_shop_redirect\', function($shop_url) {
       if(is_cart() && wc()->cart->cart_contents_count == 0) {
       $deleted_items = wc()->cart->get_removed_cart_contents();
       $deleted_items = array_reverse($deleted_items);
       foreach($deleted_items as $deleted_item) {
       $deleted_id = (int) $deleted_item[\'product_id\'];
       $vendor_id = wcfm_get_vendor_id_by_post($deleted_id);
       if($vendor_id) {
       return wcfmmp_get_store_url($vendor_id);
       }
       }
       }
       return $shop_url;
       });
       ```

 * Hi, [@teamgood](https://wordpress.org/support/users/teamgood/)!
 * Could you ask the theme developer? Or, as [@jdembowski](https://wordpress.org/support/users/jdembowski/)
   mentioned, ask in the WooCommerce support forum?
 * Otherwise, you could try to debug the problem yourself activating the debug mode.
   Here’s how: [Debugging in WordPress](https://wordpress.org/support/article/debugging-in-wordpress/).
 * Also, just to make sure, there are some escaped quotes in your code. Maybe that
   was due to pasting the code here, but the code look like this:
 *     ```
       add_filter( 'woocommerce_return_to_shop_redirect', function($shop_url) {
           if(is_cart() && wc()->cart->cart_contents_count == 0) {
             $deleted_items = wc()->cart->get_removed_cart_contents();
             $deleted_items = array_reverse($deleted_items);
             foreach($deleted_items as $deleted_item) {
               $deleted_id = (int) $deleted_item['product_id'];
               $vendor_id = wcfm_get_vendor_id_by_post($deleted_id);
               if($vendor_id) {
                 return wcfmmp_get_store_url($vendor_id);
               }
             }
           }
           return $shop_url;
         });
       ```
