問(wèn)題描述

我正在嘗試將一個(gè)變量從一個(gè)視圖傳遞到另一個(gè)視圖的控制器.我沒(méi)有收到任何錯(cuò)誤，但是當(dāng)它進(jìn)入最后一個(gè)視圖時(shí)，它沒(méi)有像預(yù)期的那樣顯示變量.在第一個(gè)視圖中，我只是得到一個(gè)名字.

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.

{{ Form::open(array('route' => 'form', 'method'=>'post')) }}
    {{ $name = Form::text('name') }}
    {{ Form::submit('Go!') }}
{{ Form::close() }}

這是我的 HomeController.php.

Here is my 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

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>

那為什么不顯示呢?

推薦答案

首先你應(yīng)該把你的 postView 函數(shù)改成:

First you should change your postView function into:

public function postView1()
{
    return Redirect::route('view2', ['name' => Input::get('name')]);
}

還有你的路線:

Route::post('form/{name}', array('as' => 'form', 'uses'=>'HomeController@postView1'));

進(jìn)入:

Route::post('form', array('as' => 'form', 'uses'=>'HomeController@postView1'));

現(xiàn)在，您應(yīng)該將 view2 函數(shù)更改為:

Now, you should change your view2 function into:

public function view2($name)
{
    return View::make('view2')->with('name',$name);
}

現(xiàn)在在您的 view2.blade.php 中，您應(yīng)該可以使用:

Now in your view2.blade.php you should be able to use:

<p> Hello, {{ $name }} </p>
