致命错误：调用function.php中的非对象的成员函数add_to_cart（）

Question

我正在自定义woo-commerce插件以将产品从前端添加到购物车中。我已经在functions.php中写了这个函数，但是我得到了一个致命错误。任何机构有任何想法如何解决它？

if (isset($_POST["addcustomcarts"])) 
      { 
      echo $_SERVER[QUERY_STRING]; 
      // echo $_SERVER[REQUEST_URI]; 
      echo "i am in if"; 
      //exit(); 
     add_filter('woocommerce_before_cart', 'customcart'); 

     function customcart() { 
      echo "i am in function"; 

     //global $woocommerce; 

     $my_post = array(
      'post_title' => 'My post', 
      'post_content' => 'This is my post.', 
      'post_status' => 'publish', 
      'post_author' => 1, 
      'post_type'  =>'product' 

     ); 


     // Insert the post into the database 
     $product_ID=wp_insert_post($my_post); 

     add_post_meta($product_ID, '_regular_price', 100, $unique); 
     add_post_meta($product_ID, '_price', 100, $unique); 
      add_post_meta($product_ID, '_stock_status', 'instock', $unique); 


      //Getting error on this line. 
      $woocommerce->cart->add_to_cart($product_ID, $quantity=1); 




     exit(wp_redirect(home_url("cart"))); 
     } 

     customcart(); 
      }

为什么你评论此行 // global $ woocommerce; ？我认为这可能是问题
