admin_init沒有被觸發

我編寫了一個WordPress插件，首先，我將菜單添加到WordPress，並且每個菜單回調首先觸發admin_init並且需要所需的頁面。這裏是我的邏輯admin_init沒有被觸發

<?php 

class EasySEO 
{ 

    public function __construct() 
    { 

     $this->wp_easy_seo_register_menu_page(); 
    } 

    public function wp_easy_seo_register_menu_page() 
    { 
     add_menu_page('Easy SEO : General Setting', 'Easy SEO', 'manage_options', 'wp-easy-seo-dashboard', array(
      $this, 
      'wp_easy_seo_general_cb' 
     )); 
     add_submenu_page('wp-easy-seo-dashboard', 'Easy SEO : General Setting', 'General', 'manage_options', 'wp-easy-seo-dashboard', array(
      $this, 
      'wp_easy_seo_general_cb' 
     )); 
     add_submenu_page('wp-easy-seo-dashboard', 'Title & Metas - Easy SEO', 'Title & Metas', 'manage_options', 'wp_easy_seo_title', array(
      $this, 
      'wp_easy_seo_title_cb' 
     )); 
     add_submenu_page('wp-easy-seo-dashboard', 'Verify Domain Ownership - Easy SEO', 'Domain Verification', 'manage_options', 'wp_easy_seo_domain_ownership_verify', array(
      $this, 
      'wp_easy_seo_domain_ownership_verify_cb' 
     )); 
     add_submenu_page('wp-easy-seo-dashboard', 'Web Traffic Statistics - Easy SEO', 'Traffic Statistics', 'manage_options', 'wp_easy_seo_traffic_statistics', array(
      $this, 
      'wp_easy_seo_traffic_statistics_cb' 
     )); 

    } 

    function wp_easy_seo_general_cb() 
    { 



    } 

    function wp_easy_seo_title_cb() 
    { 
     add_action('admin_init', function() 
     { 
      require 'wp_easy_seo_title.php'; 
     }); 


    } 

    function wp_easy_seo_domain_ownership_verify_cb() 
    { 
     require 'wp_easy_seo_domain_ownership_verify.php'; 
    } 


    function wp_easy_seo_traffic_statistics_cb() 
    { 
     require 'wp_easy_seo_traffic_statistics.php'; 
    } 


} 

add_action('admin_menu', function() 
{ 
    new EasySEO; 
}); 
?>

Admin_init沒有得到觸發，這就是爲什麼下一個頁面沒有加載。我試過echo 1;退出;而是要求檢查代碼是否流入我的回聲1;仍然失敗。

這是我wp_easy_seo_title頁：

<?php 

class EasySEO_Options { 

    public $options; 

    public function __construct() { 

     $this->options= get_option('wp_easyseo_homepage_options'); 

     $this->easy_seo_display_options_page(); 
     $this->wp_easy_seo_register_settings_and_field(); 

    } 

    public function easy_seo_display_options_page() { 

     ?> 
     <div class='wrap'> 
      <h2>Title & Metas - Easy SEO</h2> 
      <form action="options.php" enctype="multipart/form-data" method="POST"> 
     <?php 


     settings_fields('wp_easyseo_homepage_options'); 
     do_settings_sections('wp_easy_seo_title'); 

     ?> 

       <p class="submit"> 
        <input name='submit' type='submit' class='button-primary' value='Save Changes'/> 

       </p> 
      </form> 

     </div> 
     <?php 

    } 



    public function wp_easy_seo_register_settings_and_field() { 


     register_setting('wp_easyseo_homepage_options', 'wp_easyseo_homepage_options'); 
     add_settings_section('wp-easyseo-main-settings', 'Title & Metas', array($this, 'wp_easyseo_main_settings_cb'), 'wp_easy_seo_title'); 
     add_settings_field('wp-easy-seo-title', 'Meta Title', array($this, 'wp_easy_seo_title_cb'), 'wp_easy_seo_title', 'wp-easyseo-main-settings'); 
     add_settings_field('wp-easy-seo-description', 'Meta Description', array($this, 'wp_easy_seo_description_cb'), 'wp_easy_seo_title', 'wp-easyseo-main-settings'); 
    } 

    public function wp_easyseo_main_settings_cb() { 

    } 

    /** 
    * Inputs 
    */ 
    public function wp_easy_seo_title_cb() { 

     echo "<input name='wp_easyseo_homepage_options[wp-easy-seo-title]' value='{$this->options['wp-easy-seo-title']}' type='text'/>"; 
    } 

    public function wp_easy_seo_description_cb() { 
     echo "<input name='wp_easyseo_homepage_options[wp-easy-seo-description]' value='{$this->options['wp-easy-seo-description']}' type='text'/>"; 
    } 

} 

new EasySEO_Options; 


?>

現在，你要add_action('admin_init'...調用一個函數wp_easy_seo_title_cb它不會被調用，直到某個時候被渲染菜單時的內部。這是在admin_init已經發生之後，所以它被註冊得太晚。

嘗試將所有呼叫移動到add_action到您班級的構造函數。

我發現在構造函數中註冊所有的動作是很好的，以保持事物的組織性並確保所有的事情都被及時註冊。

<?php 

class SomePlugin { 

    public function __construct() { 
     add_action('admin_init', array($this, 'some_callback')); 
     add_action('transition_post_status', array($this, 'other_callback')); 
     // etc 
    } 

    public function some_callback() { 
     // Do something 
    } 

    public function other_callback() { 
     // Do something 
    } 
} 

new SomePlugin();

這樣，當文件被加載時，它立即註冊它的所有動作鉤子。除了註冊鉤子之外，其他構造函數都不會發生，因爲構造函數將在每頁加載時運行。
