How can I remove the "bulk actions" based on user roles or capabilities. Actually I have this code to do the job, but now I need to exclude the site admin, I need to let the administrator to access the bulk menu
add_filter( 'bulk_actions-' . 'edit-post', '__return_empty_array' );
add_filter( 'bulk_actions-' . 'upload', '__return_empty_array' );
How can I exclude roles or capabilities from that filter ?
