User Contributed Notes

  1. Skip to note 6 content

    This filter allows you to set subscribers as authors of blog posts within the admin without giving them additional privileges. Here’s the code:

    add_filter( 'wp_dropdown_users_args', 'wpdocs_add_subscribers_to_dropdown' );
    function wpdocs_add_subscribers_to_dropdown( $query_args ) {
        $query_args['who'] = '';
        return $query_args;
  2. Skip to note 7 content

    In addition to Jonathan’s contribution, you can also expand it further by specifying the role. This is undocumented on wp codex. But does work e.g.

    function wpdocs_add_subscribers_to_dropdown( $query_args, $r ) {
    	$query_args['role'] = array('contributor');
    	// Unset the 'who' as this defaults to the 'author' role
    	unset( $query_args['who'] );
    	return $query_args;
    add_filter( 'wp_dropdown_users_args', 'wpdocs_add_subscribers_to_dropdown', 10, 2 );
  3. Skip to note 8 content

    In addition to RiseOfLex88’s contribution, you can also specify multiple roles.

    function wpdocs_add_subscribers_to_dropdown( $query_args ) {
    	// Use this array to specify multiple roles to show in dropdown
        $query_args['role__in'] = array( 'contributor', 'administrator' );
    	// Use this array to specify multiple roles to hide in dropdown
        $query_args['role__not_in'] = array( 'editor' );
        // Unset the 'who' as this defaults to the 'author' role
        unset( $query_args['who'] );
        return $query_args;
    add_filter( 'wp_dropdown_users_args', 'wpdocs_add_subscribers_to_dropdown' );

    If you dump variable “$query_args” inside this function, this is what you will get:

    array(10) { 
      ["blog_id"]=> int(1) 
      ["include"]=> string(0) "" 
      ["exclude"]=> string(0) "" 
      ["orderby"]=> string(12) "display_name" 
      ["order"]=> string(3) "ASC" 
      ["who"]=> string(7) "authors" 
      ["role"]=> string(0) "" 
      ["role__in"]=> array(0) { } 
      ["role__not_in"]=> array(0) { } 
      ["fields"]=> array(3) { 
        [0]=> string(2) "ID" 
        [1]=> string(10) "user_login" 
        [2]=> string(12) "display_name" 
  4. Skip to note 9 content

    Note that if you’re trying to filter the “Author” dropdown on the post editor screen, and the post editor is using Gutenberg, this filter doesn’t fire. You’ll need to work with the rest_user_query filter instead. (But also note that this filter is used for a lot more than the Author dropdown, so use it thoughtfully.)

  5. Skip to note 10 content

    For this to work with Subscribers, you’ll also need to adjust the capability:

    // Show Subscribers in the 'author' drop down on the classic post editor
    function wpdocs_add_subscribers_to_dropdown( $query_args ) {
        $query_args['who'] = ''; // reset the query
        $query_args['capability'] = ''; // reset the query
        $query_args['role__in'] = array( 'administrator', 'subscriber', 'author', 'editor' );
        $query_args['capability__in'] = array( 'edit_own_posts' ); // Custom capability for subscribers
        return $query_args;
    add_filter( 'wp_dropdown_users_args', 'wpdocs_add_subscribers_to_dropdown' );
