如果已经存在，我尝试添加远程方法来检查显示名称。
如果电子邮件已经存在，则电子邮件验证可以检查和显示消息，但显示名称验证不起作用。我的代码出了什么问题？
我的代码
register.php
<?php require_once 'config.php'; ?>
<?php
if(!empty($_POST)){
try {
$user_obj = new Cl_User();
$data = $user_obj->registration( $_POST );
if($data)$success = USER_REGISTRATION_SUCCESS;
} catch (Exception $e) {
$error = $e->getMessage();
}
}
?>
