Question

我正在尝试让init函数仅在post_type为shop_order且使用以下代码的情况下发生。我的意图是在编辑模式下将元框显示为管理订单/单击创建新订单时，但是在get_post_type中的以下代码为shop_order时，该元框未出现在管理订单编辑视图中。

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

    class DM_Apply_Order_Discount {

      public function __construct()
      {
        $this->init();
      }

      public function init() {
      global $post;
      $postid = $post->ID;
      if( get_post_type($postid) === 'shop_order' ) {
        add_action('add_meta_boxes', array($this, 'add_apply_discount_container'));
        add_action('admin_enqueue_scripts', array($this, 'enqueue_scripts'));
    }}

      public function enqueue_scripts() {
        wp_enqueue_script('hellodev-discount-manager-js', plugins_url('js/hellodev-discount-manager-apply-discount-min.js', DM_PLUGIN_FILE), array(), '1.0', false);
        wp_localize_script('hellodev-discount-manager-js',
        'hellodev_discount_manager_locales',
        array(
          'confirm_apply_discount' => __('Applying the discount will overwrite existing discounts. Do you want to continue?', 'hellodev-discount-manager-apply-discount'),
          'apply_success_message' => __('Saved with success.', 'hellodev-discount-manager-apply-discount'))
        );
      }

      public function add_apply_discount_container() {
        global $post_id;
        $order = new WC_Order($post_id);
        if (!$order->is_editable()) {
          return;
        }
        add_meta_box('hellodev-discount-manager-apply-discount-container', __('Apply discount to all items', 'hellodev-discount-manager-apply-discount'),
        array($this, 'create_apply_discount_container'), 'shop_order', 'side');
      }

      public function create_apply_discount_container() {
        ?>
        <ul id="hellodev-discount-manager-apply-discount" class="hellodev-discount-manager-apply-discount">
          <li>
            <input id="hellodev-discount-manager-apply-discount-percentage" type="number" name="discount" min="0" max="100" step="1"
            placeholder="<?php _e("Discount in percentage (%)", "hellodev-discount-manager-apply-discount") ?>" style="width: 100%"/>
          </li>
        </ul>
        <?php
      }
    }

    new DM_Apply_Order_Discount();

出了什么问题？

请使用全局$ post与$ post_id进行核对；

public function init() {
  global $post;
  $postid = $post->ID;   
  if( get_post_type($postid) === 'shop_order' ) {
    add_action('add_meta_boxes', array($this, 'add_apply_discount_container'));
    add_action('admin_enqueue_scripts', array($this, 'enqueue_scripts'));
}}

希望对您有帮助。

仅当post_type为shop_order时才执行函数初始化
