laravel passing errors to views through controllers
提问by spacemonkey
I am trying to validate in an action within my controller. once it fails, I send the messages resulting from the validator to the other function in the same controller to pass it to the view. The only problem is I don't see anything displaying in the view and the url changes to a weird format once I click submit and errors occurs.
我正在尝试在我的控制器中的一个操作中进行验证。一旦失败，我会将验证器产生的消息发送到同一控制器中的另一个函数，以将其传递给视图。唯一的问题是我没有看到视图中显示任何内容，并且一旦我单击提交并发生错误，url 就会更改为奇怪的格式。
Controller:
控制器：
<?php
class MembersController extends BaseController {
protected $layout = 'layouts.master';
public function loadRegisterView($input = null)
{
if($input == null)
return View::make('members.register');
else
return View::make('members.register', $input);
}
public function loadLoginView()
{
return View::make('members.login');
}
public function register()
{
$rules = array(
'first_name' => 'Required|Min:3|Max:88|Alpha',
'last_name' => 'Required|Min:3|Max:88|Alpha',
'password' => 'Required|Min:3|Max:88|Alpha|Confirmed',
'email' => 'Required|email|unique:users',
);
$validator = Validator::make(Input::all(), $rules);
if ($validator->fails())
{
$messages = $validator->messages();
return Redirect::action('MembersController@loadRegisterView', $messages);
}else{
return "Thank you!";
}
}
}
Routes:
路线：
Route::get('login', array('as' => 'login', 'uses' => 'MembersController@loadLoginView'));
Route::get('signup', array('as' => 'signup', 'uses' => 'MembersController@loadRegisterView'));
Route::get('/', 'MainController@index');
Route::post('processRegistration', array('as' => 'processRegistration', 'uses' => 'MembersController@register'));
in the View:
在视图中：
@if ( $errors->count() > 0 )
<p>The following errors have occurred:</p>
<ul>
@foreach( $errors->all() as $message )
<li>{{ $message }}</li>
@endforeach
</ul>
@endif
and the URL looks like:
网址如下所示：
http://localhost:8888/store/index.php/signup?%00%2A%00messages%5Bfirst_name%5D%5B0%5D=The+first+name+field+is+required.&%00%2A%00messages%5Blast_name%5D%5B0%5D=The+last+name+field+is+required.&%00%2A%00messages%5Bpassword%5D%5B0%5D=The+password+field+is+required.&%00%2A%00messages%5Bemail%5D%5B0%5D=The+email+field+is+required.&%00%2A%00format=%3Amessage
Thanks in advance
提前致谢

You pass variable directly to the route, wile you should do:
您将变量直接传递给路线，您应该这样做：
if ($validator->fails())
{
$messages = $validator->messages();
return Redirect::action('MembersController@loadRegisterView')->withErrors($messages);
}else{
return "Thank you!";
}
