  2018年10月 - 改进的更新代码版本：禁用Woocommerce中特定类别的购物车项目的其他产品类别

  请尝试以下代码：

  • 当特定产品类别的产品在购物车中时，避免添加到购物车

  • 将特定产品类别的产品添加到购物车时，删除其他购物车项目

  代码：

  // Remove other items when our specific product is added to cart
  add_action( 'woocommerce_add_to_cart', 'remove_other_products_on_add_to_cart', 10, 6 );
  function remove_other_products_on_add_to_cart ( $cart_item_key, $product_id, $quantity, $variation_id, $variation, $cart_item_data ){
      // HERE set your product category (can be term IDs, slugs or names)
      $category = 'posters';
  
      // We remove other items when our specific product is added to cart
      if( has_term( $category, 'product_cat', $product_id ) ) {
          foreach( WC()->cart->get_cart() as $item_key => $cart_item ){
              if( ! has_term( $category, 'product_cat', $cart_item['product_id'] ) ) {
                  WC()->cart->remove_cart_item( $item_key );
              }
          }
      }
  }
  
  // Avoid other items to be added to cart when our specific product is in cart
  add_filter( 'woocommerce_add_to_cart_validation', 'check_and_limit_cart_items', 10, 3 );
  function check_and_limit_cart_items ( $passed, $product_id, $quantity ){
      // HERE set your product category (can be term IDs, slugs or names)
      $category = 'posters';
  
      // We exit if the cart is empty
      if( WC()->cart->is_empty() )
          return $passed;
  
      // CHECK CART ITEMS: search for items from product category
      foreach ( WC()->cart->get_cart() as $cart_item ){
          if( has_term( $category, 'product_cat', $cart_item['product_id'] ) ) {
              // Display an warning message
              wc_add_notice( __('A subscription is already in cart (Other items are not allowed in cart).', 'woocommerce' ), 'error' );
              // Avoid add to cart
              return false;
          }
      }
      return $passed;
  }
  

  代码位于活动子主题（或活动主题）的function.php文件中 . 经过测试和工作 .
