这是我的代码:
public function store(Request $request){
$this->validate($request, [
'name' => 'required',
'email' => 'required|email',
'content' => 'required|min:10',
]);
$new_array = array();
$new_array['name'] = $request->name;
$new_array['email'] = $request->email;
$new_array['content'] = $request->content;
contact::create($new_array);
return back();
}
现在我需要为这些过滤器设置一些新的错误消息(例如:required
,email
,..)。
目前,这是required
的默认错误消息:
名称字段是必需的。
如何更改?

Crate规则
public function user_registration_rules(array $data)
{
$messages = [
'full-name.required' => 'Please enter full name',
'address.required' => 'Please enter address'
];
$validator = Validator::make($data, [
'full-name' => 'required|min:5|max:70',
'address' => 'required'
], $messages);
return $validator;
}
在像这样的控制器中使用
$validator = $this->user_registration_rules($request_data);
if($validator->fails())
{
return redirect()->back()->withErrors($validator)->withInput();
}

您可以使用以下命令
创建用于处理验证的Laravel请求php artisan make:request RequestName
您将在app \ Http \ Request
中找到该文件在文件中你会找到rules()函数,你可以在其中提到所有规则
public function rules()
{
return [
'name' => 'required',
];
}
您可以为自定义消息创建message()函数,例如
public function messages()
{
return[
'name.required' => 'The name field is required.'
];
}
在控制器方法
中添加此请求public function methodName(RequestName $request)
{
//Your code
}

您可以像这样修改验证器:
$validator = Validator::make($request, [
'name' => 'required',
'email' => 'required|email',
'content' => 'required|min:10',
]);
现在您将能够捕获验证错误:
if ($validator->fails()) {
$error_message = $validator->errors()->all();
// Write Custom Validator Error Message according to the $error_message found.
}
Laravel Validator无论如何都会提供非常全面的错误消息。

关注此: 查看:
<div class="col-md-3">
{{Form::label('Deposit Amount')}}
{{Form::text('deposit_amount',Input::old('deposit_amount'),array('class'=>"form-control"))}}
<span class="error">{!!$errors->first('deposit_amount')!!}</span>
</div>
控制器
use App\Http\Requests;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Input;
use DB;
use Hash;
use Auth;
use App\PaymentModel;
use Redirect;
use Response;
class TransactionController extends Controller
{
public function payment(Request $request){
$validator = Validator::make(Input::all(), PaymentModel::Rules(), PaymentModel::$message);
if ($validator->fails())
{
return \Redirect::back()->withErrors($validator)->withInput();
}
else
{
$deposit_amount=Input::get("deposit_amount");
$obj = new PaymentModel();
$obj->deposit_amount=$deposit_amount;
if ($obj->save()) {
Session::flash('success', 'Saved Successfully !!');
} else {
Session::flash('error', 'Some thing went wrong!!');
}
}
return Redirect::action('TransactionController@payment');
}
}
模型
public static function Rules(){
$rules= array(
'deposit_amount'=>'required|numeric',
);
return $rules;
}
public static $messages=array(
'deposit_amount.required'=>'Please Enter Amount ',
'deposit_amount.numeric'=>'Deposit Amount Must be a number ',
);

来自文档:https://laravel.com/docs/5.3/validation#customizing-the-error-messages
您可以通过覆盖messages方法来自定义表单请求使用的错误消息。此方法应返回属性/规则对的数组及其相应的错误消息:
/**
* Get the error messages for the defined validation rules.
*
* @return array
*/
public function messages()
{
return [
'title.required' => 'A title is required',
'body.required' => 'A message is required',
];
}
这只是来自文档的复制粘贴。你应该参考laravel docs,它们是最好的文档之一。
