I thought I would add this as a quick follow on from my previous tutorial showing you how to make a login form in your WordPress sidebar (find it here), it used a technique to show a menu once a user had logged in.

So if you want to hide a menu from readers but show it to registered users you could use the following example:

Say you had a menu that looked something like this in your sidebar:

Registered User Menu

Registered user menu options here!

If you only wanted registered users to be able to see and use this menu simply add <?php if ( ! is_user_logged_in() ){ ?> before the code above and of course close the php statement with <?php }?> at the end of it. Nice one now only registered, logged in users can see the menu!

What if you need a menu that only appears to users of a certain level? Well can use another handy php staement. Place <?php if (current_user_can('level_10')){ ?> at the beginning of your menu code block and close it again with <?php }?>. This example will show the menu only to admins ‘level_10′ you can change this to suit whichever user level you want. Below is the standard wordpress user level list:

Administrator: level_10
Editor: level_7
Author: level_2
Contributor: level_1
Subscriber: level_0 (although you would never use this as you could use is_user_logged_in() function)

You can of course create your own user roles and levels using this plugin
