我想给用户提供功能，而他们的帐户是由管理员在wordpress中创建的，此时设置密码的电子邮件会发送给用户，其中包含带有激活密钥、登录和操作的自定义页面链接。我已经创建了一个短代码，用于在页面中从前端设置密码。我能够从url获取数据，并设法检查密码是否匹配且不为空，但如何为新用户设置此密码。欢迎提供任何帮助/建议。

add_shortcode( \'RESET_PASSWORD\' , \'reset_password_function\' );
function reset_password_function() { 
    global $wpdb, $user_ID;

    if(isset($_GET[\'key\']) && $_GET[\'action\'] == "rp") {
        $reset_key  = $_GET[\'key\'];
        $action     = $_GET[\'action\'];
        $user_login = $_GET[\'login\'];
        print_r($reset_key);
        echo \'<br/>\';
        print_r($action); 
        echo \'<br/>\';
        print_r($user_login); 

        // Print output like 
        // Kdfd3434Kdfrewfpd
        // rp
        // demo.test@abc.com
    }

    if($_POST[\'action\'] == "agent_pwd_reset"){
        $error = array();

        if(empty($_POST[\'new_password\'])) {
            $error[] = __(\'Can not set blank new password field\',\'AA\');
        } else {
            $agent_new_pass = $_POST[\'new_password\'];
        }

        if(empty($_POST[\'confirm_password\'])) {
            $error[] = __(\'Can not set blank confirm password field\',\'AA\');
        } elseif ($_POST[\'new_password\'] !== $_POST[\'confirm_password\']) {
            $error[] = __(\'Password not match.\',\'AA\');
        } else {
            $agent_confrim_pass = $_POST[\'confirm_password\'];
            $success = __(\'Password match.\',\'AA\');
        }

        if ( count($error) == 0 ) {
            echo \'<div class="col-md-6 col-md-offset-4 alert alert-success">\'.$success. \'</div>\'; 
            // here i want to set new password for user
        } elseif ( count($error) > 0 ) {
            echo \'<div class="col-md-6 col-md-offset-4 alert alert-danger error">\' . implode("<br />", $error) . \'</div>\'; 
        }
