1.這里只是演示一下基本的驗證規則
blade用戶登陸模板index.blade.php
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport"
content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>個人測試網頁</title>
</head>
<body>
@if(count($errors)>0)
<div class="alert-danger">
<ul>
@foreach($errors->all() as $error)
<li>{{$error}}</li>
@endforeach
</ul>
</div>
@endif
<form action="{{url('validate')}}" method="post">
{{csrf_field()}}
USERNAME:<input type="text" name="username" ><br>
PASSWORD:<input type="password" name="password"><br>
<input type="submit" value="提交">
</form>
</body>
</html>
2.路由
<?php use Illuminate\Support\Facades\Routete; Route::get('index',function (){ return view('index'); }); Route::post('validate','ValidateController@index');
3.控制器中代碼（標記的地方也是可以使用的）
<?php namespace App\Http\Controllers; use Illuminate\Http\Request; class ValidateController extends Controller { // public static $requet; public function __construct(Request $request) { self::$requet=$request; } public function index(){ $rules=['username'=>'required','password'=>'required'];//驗證信息 $message=['username.required'=>'姓名不能為空','password.required'=>'密碼不能為空'];//自定義驗證中文信息 // $data=$this->validate(self::$requet,$rules,$message); $data= \Validator::make(self::$requet->except('_token'),$rules,$message); if ($data->fails()){ return redirect('index')->withErrors($data)->withInput();//傳統提交表單 頁面會刷新，輸入框里的內容會丟失掉。//跟old使用 } } }
