Get which template being in use within WordPress-admin

2 comments

1. Basically this isn’t available in admin. You can take a look at my profile, go to my github page and grab the “current admin info” plugin. But this won’t help you much.

   This would show you the template name:

   get_page_template_slug( get_queried_object_id() );
   

   On the front end you can use the following plugin, that will display that info (it’s from another question).

   <?php
   /** Plugin Name: (#10537) »kaiser« Get Template file name */
   
   if ( ! class_exists( 'wpse10537_template_name' ) )
   {
       add_action( 'plugins_loaded', array( 'wpse10537_template_name', 'init' ) );
   
   class wpse10537_template_name
   {
       protected static $instance;
   
       public $stack;
   
       public static function init()
       {
           is_null( self :: $instance ) AND self :: $instance = new self;
           return self :: $instance;
       }
   
       public function __construct()
       {
           if ( is_admin() )
               return;
   
           add_action( 'wp', array( $this, 'is_parent_template' ), 0 );
           add_action( 'wp', array( $this, 'get_template_file' ) );
           add_action( 'template_include', array( $this, 'get_template_name' ) );
           add_action( 'wp_footer', array( $this, 'get_template_name' ), 100 );
       }
   
       public function get_template_name( $file )
       {
           if ( 'template_include' === current_filter() )
           {
               $this->to_stack(
                    "Template file"
                   ,basename( $file )
               );
               return $file;
           }
   
           // Return static var on echo call outside of filter
           if (
               current_user_can( 'manage_options' )
               AND defined( 'WP_DEBUG' )
               AND WP_DEBUG 
               )
           {
               return printf(
                    '<div><p style="text-align:center;">%s</p></div>'
                   ,implode( " &ndash; ", $this->stack )
               );
           }
       }
   
       public function get_template_file()
       {
           if ( ! is_post_type_hierarchical( get_post_type() ) )
               return;
   
           $slug = get_page_template_slug( get_queried_object_id() );
           if ( ! strstr( $slug, "/" ) )
               return $this->to_stack( "Template", $slug );
   
           // Subdirectory info
           $this->to_stack(
                "Subdirectory"
               ,strstr( $slug, "/", true )
           );
   
           $this->to_stack(
                "Template (in subdirectory)"
               ,str_replace( "/", "", strstr( $slug, "/" ) )
           );
       }
   
       public function is_parent_template()
       {
           if ( ! is_null( wp_get_theme()->parent ) )
               return $this->to_stack( 'from parent theme' );
   
           $this->to_stack( 'from current/child theme' );
       }
   
       public function to_stack( $part, $item = '' )
       {
           $this->stack[] = "{$part}: {$item}";
       }
   } // END Class wpse10537_template_name
   
   } // endif;

2. This answer was originally an edit of the OP to my other answer. I’ll correct the code later on.

   So i ended up with a pretty simple solution. This answer did get me in the right direction.

   I don’t now if this is the best way to do it but it fills my requirements:

   if ( $pagenow == 'post.php' )
   {
   
       $template = get_post_meta( $post->ID, '_wp_page_template', true );
   
       // Check page-templates, if not set -> page.php
       if ( $post->post_type == 'page' && ( empty( $template ) || 'default' == $template ) )
       {
           $template = 'page.php';
       }
       elseif( empty( $template ) )
       {
           // Check single-templates, single-{post_type}.php -> single.php order
           if ( file_exists( TEMPLATEPATH .'/single-'. $post->post_type .'.php' ) ) {
               $template = 'single-'. $post->post_type .'.php';
           }
           elseif ( ( $post->post_type == 'attachment' || $post->post_type == 'page' ) && file_exists( TEMPLATEPATH .'/'. $post->post_type .'.php' ) )
           {
               $template = $post->post_type .'.php';
           }
           elseif( $post->post_type == 'attachment' )
           {
               $template = '';
           }
           else
           {
               $template = 'single.php';
           }
       }
   
       // Read the file
       $file = implode( '', file( TEMPLATEPATH .'/' . $template ) );
   
       // Get the tags in the template, (Blocks Areas: Left, Right)
       if ( preg_match_all( '|Block Areas:(.*)$|mi', $file, $name ) )
       {
           $defined_areas = explode( ',', strtolower( $name[1][0] ) );
           $defined_areas = array_map( 'trim', $defined_areas);
       }
   }
