如何让当前用户Fullname显示在表单验证消息中

Question

我正在使用一个名为Ultimate Membership Pro的Wordpress插件，它使用Ajax调用来验证注册表单中的用户名。但是，当已注册的用户名尝试再次注册时，我希望检索该用户的全名。

示例-我希望验证消息显示:此用户名已被John Doe采用

我曾尝试操作插件目录中名为indeed membership pro.php文件的文件名。

//I added this code under the function
//I called a global method
                global $current_user;
        $uid = get_user_by('login', $value);



                            case 'user_login':
                if (!validate_username($value)){
                    $return = $register_msg['ihc_register_error_username_msg'];
                }
                if (username_exists($value)) {

      //I concatenate the error message with the input username to get the user ID. But i need the user FirstName and Lastname


                    $return = $register_msg['ihc_register_username_taken_msg'] . $uid->ID;
                }
                break;




function ihc_check_value_field($type='',  $value='', $val2='',  $register_msg=array()){

//I called a global method
                global $current_user;
        $uid = get_user_by('login', $value);


    if (isset($value) && $value!=''){

        switch ($type){
            case 'user_login':

Answer 1

$user_object->display_name就是你要找的东西。

鉴于此，将名字和姓氏等用户数据显示为错误消息的一部分可能不是一个好主意。
