在 WordPress 中注册用户后，客户表返回空

Question

虽然mysql中的wp_users和wp_wc_customer_lookup表中都存在数据，但我不确定这段代码有什么问题。在用户注册并更新我的自定义表后，我使用下面的 user_registration 挂钩从“wc_customer_lookup”获取 customer_id。请帮忙，请参考下面提供的代码。

add_action('user_register', 'map_customer_user', 10, 2);

function map_customer_user($user_id)
{

    if (isset($_COOKIE["uuid_custom"])) {

        global $wpdb;

        // Sanitize user input

        $user_id = intval($user_id);

        $table_name = $wpdb->prefix . 'custom_Table';

        // Use prepare() to avoid SQL injection

        $customer = $wpdb->get_row(
            $wpdb->prepare(
                "SELECT * FROM " . $wpdb->prefix . "wc_customer_lookup WHERE user_id = %d",
                $user_id
            )
        );

        if ($customer) {

            $data_update = array(
                'status' => 2,
                'customer' => $customer->customer_id
            );

            $data_where = array('customer_cookie_id' => $_COOKIE["uuid_custom"]);

            // Use $wpdb->update() to update data

            $wpdb->update($table_name, $data_update, $data_where);

            // Unset the cookie

            unset($_COOKIE["uuid_custom"]);

            setcookie('uuid_custom', '', time() - 3600, '/');
        } else {
            // Handle case where customer data is not found

        }
    }
}

1. 检查 wc_customer_lookup 表是否正在使用：

2. 保证待遇在客户招募前设定：

3. 调试：

   //调试语句示例 error_log('用户 ID: ' . $user_id);

4. 数据库前缀：

   add_action('user_register', 'map_customer_user', 10, 1);

函数map_customer_user($user_id) { if (isset($_COOKIE["uuid_custom"])) {

    global $wpdb;

    // Sanitize user input
    $user_id = intval($user_id);

    // Use prepare() to avoid SQL injection
    $customer = $wpdb->get_row(
        $wpdb->prepare(
            "SELECT * FROM {$wpdb->prefix}wc_customer_lookup WHERE user_id = %d",
            $user_id
        )
    );

    if ($customer) {
        $table_name = $wpdb->prefix . 'custom_Table';

        $data_update = array(
            'status'   => 2,
            'customer' => $customer->customer_id
        );

        $data_where = array('customer_cookie_id' => $_COOKIE["uuid_custom"]);

        // Use $wpdb->update() to update data
        $wpdb->update($table_name, $data_update, $data_where);

        // Unset the cookie
        unset($_COOKIE["uuid_custom"]);
        setcookie('uuid_custom', '', time() - 3600, '/');
    } else {
        // Handle case where customer data is not found
        error_log('Customer not found for user ID: ' . $user_id);
    }
}

}
