You may try this
你可以试试这个
if ($val->passes())
{
$data = array('msg' => 'yay');
}
else
{
$messages = $validator->messages();
$data = array('msg' => $messages->first('display_name'));
}
return Response::json($data);
print_r(...);in the controllerwill print the output outside of the template. On the client side you can check the msgsomething like this (using jQueryfor example)
print_r(...);在controller将打印模板外的输出。在客户端，您可以检查这样的msg事情（jQuery例如使用）
$.get('url', function(data){
if(data.msg == 'yay')
{
// success
}
else
{
// failed, so data.msg contains the first error message
}
});

Validator::make method only accepts two arguments.
Validator::make 方法只接受两个参数。

You are accessing the messages array you passed into the validator, not the error messages the validator created. Change your code to this:
您正在访问传递给验证器的消息数组，而不是验证器创建的错误消息。将您的代码更改为：
$val->messages()->first('email')
NOTE: The validator::make method accepts 3 arguments:
注意：validator::make 方法接受 3 个参数：
/**
* Create a new Validator instance.
*
* @param array $data
* @param array $rules
* @param array $messages
* @return \Illuminate\Validation\Validator
*/
public function make(array $data, array $rules, array $messages = array())
