Shortcode based on userids

We needed an extension of the shortcode with the ability to restrict based on user ID’s, here what we changed:

In /classes/Shortcodes.php we added an attribute ‘userids’ which we want to fill with a list of ID’s:

'userids' => array(),

Added to $atts…

Then in classes/Is.php we extended the accessible function with the new attribute:

public static function accessible( $who = '', $roles = array(), $userids = array(), $args = array() ) {

if ( ! is_array( $userids ) ) {
    $userids = array();
}

Then in the $who switch we changed this case:

case 'logged_in':
				if ( ! $logged_in ) {
					$exclude = true;
				} elseif ( ! empty( $roles ) || ! empty ($userids) ) {
					
				  if(empty ($userids)){
					
					// Checks all roles, should not exclude if any are active.
					$valid_role = false;

					foreach ( $roles as $role ) {
						if ( current_user_can( $role ) ) {
							$valid_role = true;
							break;
						}
					}
					
				  }else{
					  
  					// Checks all roles, should not exclude if any are active.
  					$valid_role = false;
					$cuid = get_current_user_id();
										
  					foreach ( $userids as $userid ) {
  						if ( $userid == $cuid ) {
  							$valid_role = true;
  							break;
  						}
  					}
					  
				  }

					if ( ! $valid_role ) {
						$exclude = true;
					}
				}
				break;

Feel free to use this (or add it to the Plugin)!
