Question

我是laravel 4的新手。当按下按钮时，我想在屏幕上显示一条消息。这是我的观点：

@section('content')
    <div class="page-header">
        <h3>
            Management
        <div class="pull-right">
                    {{ Form::submit('Save', array('class' => 'btn btn-small btn-info iframe')) }}
                @if(isset($pressMe))
                    {{$pressMe }}
                @endif
            </div>
        </h3>
    </div>
@stop

我的路线定义如下：

Route::get('pressMe', 'TestController@getIndex');
Route::post('pressMe', 'TestController@postTest');
Route::controller('pressMe', 'TestController');

最后这是我的测试控制器：

<?php
class TestController extends BaseController {

/**
 * Inject the models.
 */
public function __construct() {
    parent::__construct ();
}

public function getIndex() {

    // Show the page
    return View::make ( 'admin/pressMe/index' )->with('pressMe', '');;
}

/**
 * Start Test script.
 */
public function postTest() {
    $pressMe = 'It works!';

    return View::make ( 'admin/pressMe/index' )->with('pressMe', $pressMe);
}
}

然而，当按下按钮时，屏幕上不会显示任何内容。

任何建议我做错了什么？

我非常感谢你的回答！

在我的过滤器文件中，我有一个针对CSS的保护，但是，我现在收到以下错误：

Illuminate\Session\TokenMismatchException thrown with message ""

这是我的过滤器：

Route::filter('csrf', function()
{
    if (Session::getToken() != Input::get('csrf_token') &&  Session::getToken() != Input::get('_token'))
    {
        throw new Illuminate\Session\TokenMismatchException;
    }
});

我做错了什么？

您的代码段中包含大量已完成的代码。

视图：

你有一个提交按钮，但你没有表格。使用ajax或javascript提交表单或更简单，只需编写表单。

@section('content')
    <div class="page-header">
        <h3>
            Management
        <div class="pull-right">
             <form method="post" action="/pressMe">
               <input type="submit" class="btn btn-small btn-info iframe" value="Save" />
             </form>

             @if(Session::has('pressMe'))
               {{Session::get('pressMe')}}
             @endif 

            </div>
        </h3>
    </div>
@stop

删除

 @if(isset($pressMe))
   {{$pressMe }}
 @endif

并添加此内容，

@if(Session::has('pressMe'))
    {{Session::get('pressMe')}}
@endif

就像我在视图代码段中所做的那样

在路线档案中：

Route::get('pressMe', 'TestController@getIndex');
Route::post('pressMe', 'TestController@postTest');

删除Route::controller('pressMe', 'TestController');

不要混淆手动路由和控制器路由。它会让你头疼。坚持一个。控制器路由，手动路由或Restful路由。 不要混用！

在测试控制器中：

public function postTest() {
    $pressMe = 'It works!';

    return Redirect::to('/pressMe')->with('pressMe', $pressMe);
}

.... 你已经完成了。

更新＃1

查看：

<form method="post" action="{{URL::action('TestController@postTest')}}">

和

<强>的TestController：

return Redirect::action('TestController@postTest')->with('pressMe', $pressMe);

按下按钮时显示控制器的var
