Question

我正在尝试与我的ERP一起检查是否有库存产品。因此，当您选择添加到购物车时，我将运行代码检查是否有库存，然后将其删除（如果无库存）。我想显示一条消息，说该产品已删除，导致缺货。

   function custom_validate_stock() {
       if(1==1){
           $stockERP = 0;
           if($stockERP < 1){
               if ( sizeof( WC()->cart->get_cart() ) > 0 ) {
                   foreach ( WC()->cart->get_cart() as $cart_item_key => $values ) {
                       $_product = $values['data'];
                       if ( $_product->id == $product->id ){
                           WC()->cart->remove_cart_item($cart_item_key);
                           $removed = true;
                           break;
                       }
                   }
               }
           }
           if($removed){
               remove_action( 'woocommerce_cart_is_empty', 'wc_empty_cart_message', 10 );
               add_action( 'woocommerce_cart_is_empty', 'custom_empty_cart_message', 10 );
       
               
           }
       }
   }

   function custom_empty_cart_message() {
       $html  = '<div class="col-12 offset-md-1 col-md-10"><p class="cart-empty">';
       $html .= wp_kses_post( apply_filters( 'wc_empty_cart_message', __( 'Your product is out of stock, please refresh the page.', 'woocommerce' ) ) );
       echo $html . '</p></div>';
   }

              currentIndex = index;
              print("$currentIndex ${orientation.toString()}");

              /// Get orientation & index of swiped card!
            },
          ),
        ),
      ),
    );
  }
}

我想您可以添加一个通知：

WC()->cart->remove_cart_item($cart_item_key);

WC（）->购物车-> remove_cart_item（$ cart_item_key）之后如何在购物车上显示消息-Woocommerce
