I have this string:
add_submenu_page(basename(__file__), 'Events', 'Colloqui', 'subscriber', 'BW_events', 'BW_events');
How can I let this be available to editor(s) too? I tried …
add_submenu_page(basename(__file__), 'Events', 'Colloqui', 'subscriber, editor', 'BW_events', 'BW_events');
… but didn’t work.
add_submenu_page() and similar functions accept a capability. Capabilities are slightly confusing in WordPress as every role name is a cap as well. So instead of just adding a role name, you could just take a capability that is shared between the roles of the Subscribers and the Editors.
As you can see from the capabilities and roles table in Codex, read for example is a capability that every role in WP has.
