Just like CPT capabilities those of taxonomy are also customizable, in register_taxonomy(): capabilities ‘manage_terms’ – ‘manage_categories’ ‘edit_terms’ – ‘manage_categories’ ‘delete_terms’ – ‘manage_categories’ ‘assign_terms’ – ‘edit_posts’ Since your authors only have edit_posts it works as you observe — they can assign existing terms, but not create them. You can customize capabilities for taxonomy in question and … Read more
Yes, just filter ‘user_has_cap’. You get an array with the current capabilities that you can change without touching the database. Sample Code add_filter( ‘user_has_cap’, ‘wpse_53230_catch_cap’, 10, 3 ); /** * See WP_User::has_cap() in wp-includes/capabilities.php * * @param array $allcaps Existing capabilities for the user * @param string $caps Capabilities provided by map_meta_cap() * @param array … Read more
difference between Role and Meta capabilities That would be better to ask the compare Role with Capabilities, not just Meta capabilities, but as a simple answer: A Role defines a set of tasks a user assigned the role is allowed to perform. Capabilities are assigned to Roles difference between Meta and Primitive capabilities? Meta capabilities … Read more
This is actually not hard. To add a new capability, call WP_Roles->add_cap(). You have to do this just once, because it will be stored in the database. So we use a plugin activation hook. Note to other readers: All of the following code is plugin territory. register_activation_hook( __FILE__, ‘epp_add_cap’ ); /** * Add new capability … Read more
It is hard to come up with precise answer since capabilities are often used more broadly than they imply. For example check for manage_options is usually synonym to check for admin user and can come up in contexts that don’t actually have much to do with options. Usually it will be a difference between subject … Read more
The difference is really no difference in regular (single install) WordPress. It’s in a multisite install (network) where there is a difference. In multisite, only a Super Admin (who can manage everything on the network) has delete_users capability, while an “admin” (who would own/manage a single site) can remove_users from their site, but cannot delete … Read more
User-edit role setting distinct from wp_capabilities? [closed]
I came up with a solution for your first question. i.e the tax metabox that only suggests terms from existing terms list but does not allow you to add new terms. The solution is jQuery based and modifies the default behavior of the tags (i.e non heirarchical taxonomies) meta box. Limitation: Currently it only allows … Read more
The lack of mutiple roles has irritated me for a long time since the underlying WP_User class supports multiple roles. I have even considered looking for an alternative software solution. @lpryor – after reading your post, I was re-motivated to implement it myself. It took a surprisingly short number of lines to do although I … Read more
If you have the unfiltered_html capability then you can use JS. Admins and editors have this capability by default. Personally I use a plugin for fine control of my users’ capabilities, but you can make this change easily in code: $role = get_role( ‘administrator’ ); $role->remove_cap( ‘unfiltered_html’ ); $role = get_role( ‘editor’ ); $role->remove_cap( ‘unfiltered_html’ … Read more
