add_filter WooCommerce 运输的自定义插件文件中的问题

Question

这是我的自定义插件代码：

class Class_name
{
    public function __construct()
    {
        if ( is_admin() ) {

            //Custom admin menu
            add_action( 'admin_menu', array( $this,'custom_submenu_page'));


            add_filter( 'woocommerce_package_rates', array($this , 'conditional_shipping', 10, 2 ));

        }
    }
function conditional_shipping( $rates, $packages ) {
    if ( isset( $rates['flat_rate:32'] ) ) {
    // Set the cost to 0
    $rates['flat_rate:32']->cost = 100;
}
    return $rates;
}



}


new Class_name();

我正在尝试使用这个过滤器，但他不起作用。前端没有任何反应。我不知道错误在哪里。

不是说要用滤镜吗？

更新与运输方式的税收计算有关。

您的代码中存在一些错误，例如：

add_filter( 'woocommerce_package_rates', array( $this , 'conditional_shipping', 10, 2 ) );

…应该是：

add_filter( 'woocommerce_package_rates', array( $this , 'conditional_shipping' ), 10, 2 );

或者在您的代码末尾：

new Class_name();

…应该是：

$GLOBALS['class_name'] = new Class_name();

所以你应该尝试像这样的完整代码（之前清空购物车）:

if ( ! defined( 'ABSPATH' ) ) exit; // Exit if accessed directly

if ( ! class_exists( 'Class_Name' ) ) {

    class Class_Name {

        public function __construct() {
            //Custom admin menu
            add_action( 'admin_menu', array( $this,'custom_submenu_page'));
            
            add_filter( 'woocommerce_package_rates', array( $this , 'conditional_shipping' ), 10, 2 );
        }

        public function conditional_shipping( $rates, $package ) {
            // HERE Defined Method rate ID
            $rate_key = 'flat_rate:32';
            
            // HERE Define New cost
            $new_cost = 100;
            
            ## -- 1. Set the rate cost -- ##

            if ( isset( $rates[$rate_key] ) ){
                // Get original cost
                $original_cost = $rates[$rate_key]->cost;
                // Set the new cost
                $rates[$rate_key]->cost = number_format($new_cost, 2);
                // calculate the conversion rate (for taxes)
                $conversion_rate = $new_cost / $original_cost;
            }
            
            ## -- 2. Taxes rate cost calculation (if enabled) -- ##
            
            $taxes = array();
            foreach ($rates[$rate_key]->taxes as $key => $tax){
                if( $tax > 0 ){
                    // set the new line tax cost in the array
                    $taxes[$key] = number_format($tax * $conversion_rate, 2);
                }
            }
            // Set the new taxes costs
            $rates[$rate_key]->taxes = $taxes;
            
            ## -- Return new costs -- ##
            return $rates;
        }
    }
    $GLOBALS['class_name'] = new Class_Name();
}

此代码放在插件文件中。它已经过测试并且可以工作。

You may need to refresh shipping methods:

Go to WooCommerce shipping settings and in the related shipping zone for your "Flat rate", disable / save and re-enable / save the corresponding "flat rate".
