当表单验证失败时,我正在尝试设置并传递一条 Flash 消息。验证通过后,我可以在控制器中设置 Flash 消息。
我试图覆盖protected failedValidation()
但我得到一个错误。
<?php
namespace App\Http\Requests;
use Illuminate\Foundation\Http\FormRequest; use Illuminate\Support\Facades\Validator;
class UserRequest extends FormRequest {
/**
* Determine if the user is authorized to make this request.
*
* @return bool
*/
public function authorize()
{
return true;
}
/**
* Get the validation rules that apply to the request.
*
* @return array
*/
public function rules()
{
return [
'first_name' => 'required|string|min:2|max:50',
'last_name' => 'required|string|min:2|max:50',
'date_of_birth' => 'required|date',
'gender' => 'required|in:male,female'
];
}
/**
* Handle a failed validation attempt.
*/
protected function failedValidation(\Illuminate\Contracts\Validation\Validator $validator)
{
Flash::error("Profile could not be saved!");
// alert()->error('oops ... error');
return parent::failedValidation($validator);
} }
错误:
Symfony\Component\Debug\Exception\FatalThrowableError 类 'App\Http\Requests\Flash' 未找到
我在 app.blade.php 中设置我的视图如下
<div class="flash-message">
@foreach (['danger', 'warning', 'success', 'info'] as $msg)
@if(Session::has('alert-' . $msg))
<p class="alert alert-{{ $msg }}">{{ Session::get('alert-' . $msg) }} <a href="#" class="close" data-dismiss="alert" aria-label="close">×</a></p>
@endif
@endforeach
</div> <!-- end .flash-message -->
