Have you ever wanted to write something in a post for future reference? If so, here is the solution. Before getting into the code let me first explain a little. The note that is created will be visible only to you (admin). The note will be visible only to the user who has the right to publish posts – so it’s naturally going to be admin in most cases. The function is made into a shortcode so that it will be easy for you to handle. Here the procedure to set it up.

1. Paste the below code in your theme’s functions.php file.

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

2. Paste the below code in your theme’s Stylesheet.

.prnote
{
  background-color:#ffffe0;
  border-color:#E6DB55;
  border-style: solid;
  border-width: 1px;
  padding:10px 10px;
  margin-bottom:10px;
}

3. While writing posts, use the shortcode [prnote] as shown below.

[prnote]my first note. only i can see it.[/prnote]

See the below screenshot of my post page showing the note.

That’s it. Start making notes. It’s really useful.
