Is it possible to specify two usergroups (e.g. admins and editors) into the admin menu capability field ? I tried the following but it doesnt work:

     'Page title',
     'Sub-menu title',
      array('administrator', 'editor'),

error message:

Warning: Illegal offset type in isset or empty in C:\wamp\www\wordpress\wp-includes\capabilities.php on line 712

You're not suppose to pass a role(or roles) to the capability parameter. Give it a capability only editors(or above) have and the page will be available to both admins and editors. – t31os Mar 30 '11 at 15:57

Capability parameter of add_submenu_page() function can only take a single capability, so if you are using the built in roles you can select a capability fro the long list that both administrators and editors have any og these:

  • moderate_comments
  • manage_categories
  • manage_links
  • unfiltered_html
  • edit_others_posts
  • edit_pages
  • edit_others_pages
  • edit_published_pages
  • publish_pages
  • delete_pages
  • delete_others_pages
  • delete_published_pages
  • delete_others_posts
  • delete_private_posts
  • edit_private_posts
  • read_private_posts
  • delete_private_pages
  • edit_private_pages
  • read_private_pages

As t31os said, you can use capabilities instead of roles there. One way to do this is to use core capabilities. (A more advanced method is to add a custom capability to the roles of your choice.) The default caps are in wp-admin/includes/schema.php in the functions called by populate_roles().

If you are using standard roles/caps, you can specify only admins and editors by the cap level_7 or edit_others_posts or several others.

level is deprecated for years. It may be dropped in the near future. – toscho Mar 30 '11 at 22:14
