Assuming the built-in user roles haven t been altered by a plugin, the higher roles contain all the capabilities of the lower roles. In other words, an author can do everything a contributor can do, plus a few other things. This means that if you want to modify roles, you don t have to change a capability for every possible role. Change the lowest role, and the others will inherit the new capabilities. However, it s possible to create new roles that are not cumulative, as you ll see later in this section.

If you need to change one or two capabilities, it s relatively easy to do so with a few lines of code in a plugin (see 9) or your theme functions (see 7). For example, if you want to allow any logged-in user to view your private posts and pages, you need to grant them two additional capabilities, as shown in Listing 10-6. This bit of code should go in your theme functions file or in a new plugin. Listing 10-6. Modifying an existing role < php // allow subscribers to view private posts and pages $PrivateRole = get_role('subscriber'); $PrivateRole -> add_cap('read_private_pages'); $PrivateRole -> add_cap('read_private_posts'); > The first line fetches the existing subscriber role (as an object) and assigns to it a variable. In the next two lines, you add the capabilities to read private posts and pages to our variable. That s it! Any subscribers can now read your private content and so can authors and contributors, whose roles

include all the capabilities of subscribers. (Remember that editors and administrators already had these particular capabilities.)
Creating Roles
Sometimes, rather than adding capabilities to an existing role, you need to create a whole new role. The code to do so is relatively easy. Again, place the lines in Listing 10-7 in your theme s functions.php file. Listing 10-7. Creating a new role < php add_role('privatereader', 'Private Reader', array( 'read' => 1, 'level_0' => 1, 'read_private_pages' => 1, 'read_private_posts' => 1, )); > The add_role() function requires three arguments: the role s name (for internal use), the display name, and an array of the role s capabilities. (See codex.wordpress.org/Roles_and_Capabilities for a complete list of the capabilities in WordPress.) Here, you ve given the role the same two capabilities a subscriber starts out with, read and level_0. (The level_n capabilities exist for backward compatibility; very early versions of WordPress used a 1-10 scale instead of named roles.) Then, you ve added the two roles relating to private content. The functions that check for the presence of a capability in the role array will test for Boolean values. You could use true or false, but most WordPress developers prefer to use 1 or 0. That s all it takes! Now, if you add a new user or edit an existing one, your role dropdown should include the Private Reader option, as shown in Figure 10-15.

USERS AND ROLES
If you want to modify your new role, use the same code as before, but change the get_role() function s argument to your role s internal name, as shown in Listing 10-8. Listing 10-8. Modifying the new role < php // remove ability to read private pages $PrivateRole = get_role('privatereader'); $PrivateRole -> remove_cap('read_private_pages'); > In this example, it makes sense to create a new role only if you want to keep the subscriber role as-is; otherwise; it s simpler to just modify the subscriber role. When would it make sense to create a new role
Creating a Role for Designers
Let s imagine a new scenario. You re building a large site, and you, the programmer, are sharing responsibilities with a graphic designer. You want to give your designer complete control over the content and theme design, but you don t want him editing other users, adding plugins, or importing content from other sites. You could create a whole new role and enumerate every capability you want the designer to have, as you did above for the private reader, but this role will be similar to the administrator s, and that s a lot of capabilities! Instead, duplicate the admin role and remove the eight or nine capabilities you don t want the designer to have, as shown in Listing 10-9. Listing 10-9. Creating a designer role < php $admin = get_role('administrator'); // get_role returns an object. // We want the capabilities piece, which is an array. $caps = $admin->capabilities; // Remove the stuff we don't want in the new role. unset($caps['activate_plugins']); unset($caps['edit_plugins']); unset($caps['update_plugins']); unset($caps['delete_plugins']); unset($caps['install_plugins']); unset($caps['edit_users']); unset($caps['delete_users']); unset($caps['create_users']); unset($caps['import']); // Add the new role. add_role('designer', 'Designer', $caps); > Note that WordPress s admin menus and screens don t always behave exactly as you d expect. In this case, even though you ve removed all capabilities involving plugins, the designer will still be able to
