Question

此功能会抓取我购物车中的特定产品，如果该产品存在，则会删除送货服务。例如。如果产品ID：40在购物车中，则禁用数组中的送货服务值（$ shipping_services_to_hide）。

我想向客户显示一条消息，告知他们运输限制，以警报的形式或最好将代码注入特定地点的购物车中（基于类别-no div id available-。此外，使用：之前或之后用css内容：可以接受）（不知道这部分是否可以完成）

这样做的好方法是什么？

add_filter( 'woocommerce_package_rates','hide_shipping_method_if_particular_product_available_in_cart' , 10, 2 );

function hide_shipping_method_if_particular_product_available_in_cart( $available_shipping_methods ) {

global $woocommerce;

// products_array should be filled with all the products ids 
// for which shipping method (stamps) to be restricted.
$products_array = array( 
40
);

// You can find the shipping service codes by doing inspect element using 
// developer tools of chrome. Code for each shipping service can be obtained by 
// checking 'value' of shipping option.
$shipping_services_to_hide  = array( 
  'wf_shipping_ups:12',
  'wf_shipping_ups:02',
  'wf_shipping_ups:59',
  'wf_shipping_ups:01',
  'wf_shipping_ups:13',
  'wf_shipping_ups:14',
  'wf_shipping_ups:11',
  'wf_shipping_ups:07',
  'wf_shipping_ups:54',
  'wf_shipping_ups:08',
  'wf_shipping_ups:65'
  );

// Get all products from the cart.
$products = $woocommerce->cart->get_cart();

// Crawl through each items in the cart.
foreach ( $products as $key => $item ) {
    // If any product id from the array is present in the cart,
    // unset all shipping method services part of shipping_services_to_hide array. 
    if( in_array( $item['product_id'], $products_array ) ) { 
        foreach ( $shipping_services_to_hide as &$value ) {
            unset( $available_shipping_methods[ $value ] );

        }
        break;
    }
}

// return updated available_shipping_methods;
return $available_shipping_methods;
}

您可以使用wc_add_notice()

触发通知

if( in_array( $item['product_id'], $products_array ) ) { 
    foreach ( $shipping_services_to_hide as &$value ) {
        unset( $available_shipping_methods[ $value ] );
        // add your notice here
        wc_add_notice( 'No shipping error.', 'your-plugin' ), 'notice' );
    }
    break;
}

echo仅基于if语句PHP
