Laravel 4 - how to return all validation error messages for all fields as a JSON structure?
提问by mtmacdonald
I'm upgrading from Laravel 3 to Laravel 4. My app has some AJAX-only forms that are rendered client-side (i.e. there are no server-side views). Therefore, instead of passing validation errors to views with the withErrors()method, I've been returning the validation error objects to the client as JSON structures.
我正在从 Laravel 3 升级到 Laravel 4。我的应用程序有一些仅在客户端呈现的 AJAX 表单（即没有服务器端视图）。因此，我没有使用withErrors()方法将验证错误传递给视图，而是将验证错误对象作为 JSON 结构返回给客户端。
In Laravel 3, I had this:
在 Laravel 3 中，我有这个：
$validation = Validator::make(Input::all(), $rules);
if($validation->fails())
{
return json_encode($validation->errors);
}
//else handle task
But in Laravel 4, the error messages are protected:
但是在 Laravel 4 中，错误消息受到保护：
$validation = Validator::make(Input::all(), $rules);
if($validation->fails())
{
var_dump($validation->messages());
return json_encode($validation->messages());
}
//else handle task
var_dump($validation->messages())returns:
var_dump($validation->messages())返回：
object(Illuminate\Support\MessageBag)[333]
protected 'messages' =>
array (size=1)
'delete_confirm_password' =>
array (size=1)
0 => string 'The delete confirm password field is required.' (length=46)
protected 'format' => string ':message' (length=8)
json_encode($validation->messages)returns
json_encode($validation->messages)返回
{}
Question:how do I return all the validation error messages for all fields as a JSON structure in Laravel 4?

Simply use toJson()method.
简单地使用toJson()方法。
return $validator->messages()->toJson();

Here is another way that let u add HTTP code to the response:
这是让您向响应添加 HTTP 代码的另一种方法：
return Response::json($validation->messages(), 500);

I think that this is the Laravel way to get the error messages. There are special methods to get them. So here how I do this stuff:
我认为这是 Laravel 获取错误消息的方式。有特殊的方法来获取它们。所以在这里我如何做这些事情：
return Response::json($validator->errors()->getMessages(), 400);
This produces output in the following format:
这将产生以下格式的输出：
{
"field_name": [
"Error message"
]
}
