Passing variable from controller to view - Laravel
提问by porcupine92
I'm trying to pass a variable from one view to a controller to another view. I'm not getting any errors, but when it gets to the last view, it doesn't show the variable like it's supposed to. In the first view, I'm just getting a name.
我试图将一个变量从一个视图传递到一个控制器到另一个视图。我没有收到任何错误，但是当它进入最后一个视图时，它没有像预期的那样显示变量。在第一个视图中，我只是得到一个名字。
{{ Form::open(array('route' => 'form', 'method'=>'post')) }}
{{ $name = Form::text('name') }}
{{ Form::submit('Go!') }}
{{ Form::close() }}
Here is my HomeController.php.
这是我的 HomeController.php。
public function view1()
{
return View::make('stuff');
}
public function postView1($name)
{
return Redirect::route('view2')->with($name);
}
public function view2($name)
{
return View::make('view2')->with($name);
}
routes.php
路由文件
Route::get('/', array('as' => 'stuff', 'uses' => 'HomeController@stuff'));
Route::post('form/{name}', array('as' => 'form', 'uses'=>'HomeController@postView1'));
Route::get('view2/{name}', array('as' => 'view2', 'uses' => 'HomeController@view2'));
view2.blade.php
view2.blade.php
{{ $name = Input::get('name') }}
<p> Hello, {{ $name }} </p>
So why isn't it showing up?
那为什么不显示呢？

First you should change your postViewfunction into:
首先，您应该将postView函数更改为：
public function postView1()
{
return Redirect::route('view2', ['name' => Input::get('name')]);
}
And your route:
还有你的路线：
Route::post('form/{name}', array('as' => 'form', 'uses'=>'HomeController@postView1'));
into:
进入：
Route::post('form', array('as' => 'form', 'uses'=>'HomeController@postView1'));
Now, you should change your view2function into:
现在，您应该将view2函数更改为：
public function view2($name)
{
return View::make('view2')->with('name',$name);
}
Now in your view2.blade.phpyou should be able to use:
现在，您view2.blade.php应该可以使用：
<p> Hello, {{ $name }} </p>

您需要命名变量：
public function view2($name)
{
return View::make('view2')->with('name', $name);
}

Try form will be if you using POST method why setting variable in route it will get directly on your function with post data.
如果您使用 POST 方法，请尝试表单，为什么在路由中设置变量，它将直接通过发布数据获取您的函数。
{{ Form::open(array('url' => 'form', 'method'=>'post')) }}
{{Form::text('name') }}
{{ Form::submit('Go!') }}
{{ Form::close() }}
route :-
路线 ：-
Route::post('form','HomeController@postView1');
controller function :-
控制器功能：-
public function postView1() {
$data = Input::all();
return Redirect::route('view2')->with('name', $data['name']);
}
and get data on view2 :-
并获取有关 view2 的数据：-
<p> Hello, {{ $name }} </p>

Here's what other answers are missing, straight from Laravel docs:
以下是其他缺少的答案，直接来自Laravel 文档：
Since the withmethod flashes data to the session, you may retrieve the data using the typical Session::getmethod.
由于with方法将数据闪存到会话中，您可以使用典型的Session::get方法检索数据。
So instead of {{$name}}write {{Session::get('name')}}.
所以而不是{{$name}}写{{Session::get('name')}}.
