通过插件开发wordpress模板生成

Question

我正在开发一个生成团队页面的wordpress插件。所以我需要添加一个模板页面team.php。该过程是否可以独立于主题自动执行，或者必须敦促用户手动将文件复制到模板目录。

Answer 1

你不应该像这样复制页面。要求用户创建一个只有短代码的普通页面，您可以用内容替换它。

这是做这些事情的标准方法。这个页面将告诉你如何做到这一点：http://codex.wordpress.org/Shortcode_API

例子：

//In your functions.php file 
function create_team_page($atts, $content = null){ 
    //$team_data = generate data here 
    return $team_data; 
} 
add_shortcode('team_page', 'create_team_page'); 

用户将只需创建与WordPress一个新的页面，并把简码[team_data]的内容。你的钩子会用内容替换它。

Answer 2

回答原来的问题，是的，你可以从插件添加页面模板，与任何主题无关。

这是我的代码解决方案（受Tom McFarlin启发）。

这是为插件而设计的（在插件的根目录下搜索模板文件）。这可以根据需要进行更改 - 请查看我的完整教程http://www.wpexplorer.com/wordpress-page-templates-plugin/以获得有关此解决方案的更多详细信息。这些文件的格式也与它们直接包含在主题中的格式完全相同。

要自定义，只需编辑__construct方法中的以下代码块;

$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'));
