如何添加客戶模板與wordpress插件的安裝

Question

我已經爲WordPress寫了一個插件。問題是我必須手動將自定義模板添加到wp-content\themes\them_name中的相關主題文件夾中，然後登錄到儀表板並設置頁面模板。

當停用模塊時，這並不好，因爲我必須再次從後端停用自定義模板。

有沒有辦法從插件代碼處理這個問題？

Answer 1

這是我從WordPress插件添加頁面模板的代碼解決方案（受Tom McFarlin啓發）。

這是爲插件而設計的（在插件的根目錄下搜索模板文件）。這些文件的格式也與它們直接包含在主題中的格式完全相同。這可以根據需要進行更改 - 請查看我的完整教程http://www.wpexplorer.com/wordpress-page-templates-plugin/以獲得有關此解決方案的更多詳細信息。

要自定義，只需編輯__construct方法中的以下代碼塊;

$this->templates = array(
     'goodtobebad-template.php'  => 'It\'s Good to Be Bad', 
    ); 

Full code;

class PageTemplater { 

    /** 
    * A Unique Identifier 
    */ 
    protected $plugin_slug; 

    /** 
    * A reference to an instance of this class. 
    */ 
    private static $instance; 

    /** 
    * The array of templates that this plugin tracks. 
    */ 
    protected $templates; 


    /** 
    * Returns an instance of this class. 
    */ 
    public static function get_instance() { 

      if(null == self::$instance) { 
        self::$instance = new PageTemplater(); 
      } 

      return self::$instance; 

    } 

    /** 
    * Initializes the plugin by setting filters and administration functions. 
    */ 
    private function __construct() { 

      $this->templates = array(); 


      // Add a filter to the attributes metabox to inject template into the cache. 
      add_filter(
       'page_attributes_dropdown_pages_args', 
       array($this, 'register_project_templates') 
      ); 


      // Add a filter to the save post to inject out template into the page cache 
      add_filter(
       'wp_insert_post_data', 
       array($this, 'register_project_templates') 
      ); 


      // Add a filter to the template include to determine if the page has our 
      // template assigned and return it's path 
      add_filter(
       'template_include', 
       array($this, 'view_project_template') 
      ); 


      // Add your templates to this array. 
      $this->templates = array(
        'goodtobebad-template.php'  => 'It\'s Good to Be Bad', 
      ); 

    } 


    /** 
    * Adds our template to the pages cache in order to trick WordPress 
    * into thinking the template file exists where it doens't really exist. 
    * 
    */ 

    public function register_project_templates($atts) { 

      // Create the key used for the themes cache 
      $cache_key = 'page_templates-' . md5(get_theme_root() . '/' . get_stylesheet()); 

      // Retrieve the cache list. 
      // If it doesn't exist, or it's empty prepare an array 
      $templates = wp_get_theme()->get_page_templates(); 
      if (empty($templates)) { 
        $templates = array(); 
      } 

      // New cache, therefore remove the old one 
      wp_cache_delete($cache_key , 'themes'); 

      // Now add our template to the list of templates by merging our templates 
      // with the existing templates array from the cache. 
      $templates = array_merge($templates, $this->templates); 

      // Add the modified cache to allow WordPress to pick it up for listing 
      // available templates 
      wp_cache_add($cache_key, $templates, 'themes', 1800); 

      return $atts; 

    } 

    /** 
    * Checks if the template is assigned to the page 
    */ 
    public function view_project_template($template) { 

      global $post; 

      if (!isset($this->templates[get_post_meta( 
       $post->ID, '_wp_page_template', true 
      )])) { 

        return $template; 

      } 

      $file = plugin_dir_path(__FILE__). get_post_meta( 
       $post->ID, '_wp_page_template', true 
      ); 

      // Just to be safe, we check if the file exist first 
      if(file_exists($file)) { 
        return $file; 
      } 
      else { echo $file; } 

      return $template; 

    } 


} 

add_action('plugins_loaded', array('PageTemplater', 'get_instance'));
