Sometimes, you may need to leave a private note (Only visible to admins) to a post, but there’s no built-in solution in WordPress to do it. So, here’s a nice hack I use on my blogs.

Here’s the code you need to add to your functions.php file:

 add_shortcode( 'note', 'sc_note' );  function sc_note( $atts, $content = null ) { 	 if ( current_user_can( 'publish_posts' ) ) 		return '<div class="note">'.$content.'</div>'; 	return ''; } 

Once done, simply add the following shortcode in your posts:

 [note] This is a personal note that only admins can see! [/note] 

Note that the note will be displayed with a <div class=”note”></div> tags, so you can use it to give a specific style to your notes!
