Adding a custom admin page

1 comment

1. You need just two steps:

   1. Hook into the action admin_menu, register the page with a callback function to print the content.
   2. In your callback function load the file from plugin_dir_path( __FILE__ ) . "included.html".

   Demo code:

   add_action( 'admin_menu', 'wpse_91693_register' );
   
   function wpse_91693_register()
   {
       add_menu_page(
           'Include Text',     // page title
           'Include Text',     // menu title
           'manage_options',   // capability
           'include-text',     // menu slug
           'wpse_91693_render' // callback function
       );
   }
   function wpse_91693_render()
   {
       global $title;
   
       print '<div class="wrap">';
       print "<h1>$title</h1>";
   
       $file = plugin_dir_path( __FILE__ ) . "included.html";
   
       if ( file_exists( $file ) )
           require $file;
   
       print "<p class='description'>Included from <code>$file</code></p>";
   
       print '</div>';
   }
   

   I added an example to my demo plugin T5 Admin Menu Demo to show how to do this in a sub menu and in a OOP style.
