Restrict access to the Trash folder in Posts

by

With the filter we prevent the Trash link from being printed. And with the action, redirect back to the post listing page if the user tries to access the URL directly (/wp-admin/edit.php?post_status=trash&post_type=post). add_filter( ‘views_edit-post’, ‘wpse_74488_remove_trash_link’ ); add_action( ‘admin_head-edit.php’, ‘wpse_74488_block_trash_access’ ); function wpse_74488_remove_trash_link( $views ) { if( !current_user_can( ‘delete_plugins’ ) ) unset( $views[‘trash’] ); return $views; … Read more

Restrict the user access in multi site for non-assigned blogs

Hook into init and add the shortcode in your hooked function. <?php add_action(‘init’, ‘wpse57819_add_shortcode’); /** * Adds the shortcode * * @uses add_shortcode * @return null */ function wpse57819_add_shortcode() { add_shortcode(‘restricted’, ‘wpse57819_shortcode_cb’); } Then in your callback function, you can check to see if the user … Read more
