我试图通过处理自定义帖子类型的插件插入自定义模板文件。除了包含部分的模板外，插件的其余部分都工作得很好。

class ClassName{

    public function __construct() {
        add_action( \'template_redirect\', array( $this, \'uniThemeRedirect\') );
    }


    public function uniThemeRedirect(){

        global $wp_query;
        global $wp;

        // Specific Custom Post Type
        if( $wp->query_vars["post_type"] == "videos" ){
            $templateFilename = "single-videos.php";

            if( file_exists( TEMPLATEPATH . \'/\' . $templateFilename ) ){
                $return_template = TEMPLATEPATH . \'/\' . $templateFilename;
            }
            else {
                $return_template = UNISLIDER_TEMPLATES . $templateFilename;
            }

            $this->doThemeRedirect( $return_template );
        } else {
            echo \'not working\';
        }

    }


    public function doThemeRedirect( $template_url ){
        global $post, $wp_query;
        if( have_posts() ){
            echo $template_url;
            require_once ( $template_url );
        }
        else{
            $wp_query->is_404 = true;
        }

    }

}

$handle = new ClassName();

但是当我在http://www.domain.com/videos 其中视频是我的自定义帖子类型。

我明白“不工作”意味着没有模板包含
Can anyone please help me what wrong i have done??

UPDATE: This is how i register the Custom Post Type

$labels = array(
             \'name\'=>__(\'UniVideos\', \'unislider\'), 
             \'singular_name\'=>__( \'Videos\', \'unislider\' ), 
             \'add_new\'=>__( \'Add New\', \'unislider\' ), 
             \'add_new_item\'=>__( \'Add New Video\' ), 
             \'edit_item\'=>__(\'Edit Video\'), 
             \'new_item\'=>__(\'New Video\'), 
             \'view_item\'=>__(\'View Videos Images\'), 
             \'search_item\'=>__(\'Search Slide\'), 
             \'not_found\'=>__(\'Noting Found\'), 
             \'not_found_in_trash\'=>__(\'Nothing found in Trash\'), 
             \'parent_item_colon\'=>\'\'
         );

         $args = array(
             \'labels\'=>$labels, 
             \'public\'=>true, 
             \'has_archive\'=>true, 
             \'publicly_queryable\'=>true, 
             \'show_ui\'=>true, 
             \'query_var\'=>true, 
             \'menu_icon\'=>\'\', 
             \'rewrite\'=>true, 
             \'capability_type\'=>\'post\', 
             \'hierarchical\'=>false, 
             \'menu_position\'=>NULL, 
             \'supports\'=>array( \'title\' )
         );

         register_post_type( \'videos\', $args );
