我有以下代码：

<?php

    global $upme;
    add_shortcode(\'upme_latest_members_list\', array($this,\'latest_members_list\'));
}

public function latest_members_list($atts){
    global $upme_template_loader,$upme_list_card_params;
    extract( shortcode_atts( array(
        \'limit\'   => 10 ,
        \'user_role\' => \'\',
        \'template\' => \'members_icon_mini\',
      ), $atts ) );

    $admin_users = get_users(\'role=administrator&orderby=registered&order=DESC\');
    $admin_users_list = array();
    foreach ($admin_users as $admin_user) {
        array_push($admin_users_list,$admin_user->ID);
    }

    $display = \'\';

    $args = array(
