Listing comment author role code problem

Need to create admin user without capability to create user

Adapt the easier way. Install a plugin (Ex. Members) that can manage roles. Create one role with restricted access in your case a role with all the capabilities but not ‘create_users’, ‘add_user’, ‘list_users’,. Save this new role and assign it to the user you want to grant these restricted privileges.

Author capabilities: Deleting comments on their own published posts

You can add the capability by using add_cap. But as far as I know there is no way to do this only for their posts, so it would be for all posts.

Hide user fields based off capability

Try this function modify_contact_methods($profile_fields) { if(current_user_can(‘edit_users’)) { // Field addition and removal will be done here // Add new fields $profile_fields[‘company_name’] = ‘Company Name’; $profile_fields[‘company_id’] = ‘Company ID’; } return $profile_fields; } add_filter(‘user_contactmethods’, ‘modify_contact_methods’);

Reading about roles and capabilities: http://codex.wordpress.org/Roles_and_Capabilities A default set of capabilities is pre-assigned to each role, but other capabilites can be assigned or removed using the add_cap() and remove_cap() functions. New roles can be introduced or removed using the add_role() and remove_role() functions. Add a capability: http://codex.wordpress.org/Function_Reference/add_cap If you … Read more

Custom post type media upload error with custom user role

This is very strange. I have got it working by setting edit_others_posts and edit_private_posts to true!

Add role and edit page capabilities

The edit_pages capability only allows a user to edit his own unpublished pages. It does neither allow to edit others pages (this would require the edit_others_pages capability) nor does it allow to publish or edit published pages (capabilities: publish_pages and edit_published_pages). I’d strongly recommend having a look on this wonderful table: https://codex.wordpress.org/Roles_and_Capabilities#Capability_vs._Role_Table listing up all … Read more
