Validation not working in laravel 5.5
提问by MMY
I installed a new Laravel 5.5 app and created a form in test.blade.phpview:
我安装了一个新的 Laravel 5.5 应用程序并在test.blade.php视图中创建了一个表单：
<!DOCTYPE html>
<html>
<head>
<title></title>
</head>
<body>
<form method="POST" action={{ route('contact') }}>
{{ csrf_field() }}
<input type="text" name="title">
<input type="text" name="body">
<input type="submit" value="click">
</form>
</body>
</html>
and created my PageController:
并创建了我的PageController：
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class Pagecontroller extends Controller
{
public function index(Request $request){
$this->validate($request,[
'title' => 'required',
'body' => 'required',
]);
return View('View');
}
}
and in the web.phpadd my routes:
并在web.php添加我的路线：
<?php
Route::get('/', function () {
return view('welcome');
});
Route::get('/test',function(){
return View('test');
});
Route::post('/contact',['uses'=>'PageController@index','as'=>'contact']);
My problem is when I submit the form with or without data nothing happen and the page just reload and when I remove the validation code:
我的问题是，当我提交有或没有数据的表单时，什么也没有发生，页面只是重新加载，当我删除验证代码时：
$this->validate($request,[
'title' => 'required',
'body' => 'required',
]);
it return the requests I can't understand what is the problem because I tested it before and it was working in Laravel 5.4. Can any one help me?
它返回的请求我不明白是什么问题，因为我之前测试过它并且它在 Laravel 5.4 中工作。谁能帮我？
采纳答案by Shiraz Coders
namespace App\Http\Controllers;
use Illuminate\Http\Request;
class Pagecontroller extends Controller
{
public function index(Request $request){
$request->validate([
'title' => 'required',
'body' => 'required',
]);
return View('View');
}
}
And your view code should be:
你的视图代码应该是：
<!DOCTYPE html>
<html>
<head>
<title></title>
</head>
<body>
@if ($errors->any())
<div class="alert alert-danger">
<ul>
@foreach ($errors->all() as $error)
<li>{{ $error }}</li>
@endforeach
</ul>
</div>
@endif
<form method="POST" action={{ route('contact') }}>
{{ csrf_field() }}
<input type="text" name="title">
<input type="text" name="body">
<input type="submit" value="click">
</form>
</body>
</html>
