Question

您好我试图删除名为projecttasks的数据透视表中的一行，然后返回当前页面，我删除了一个项目任务。以下是我浏览器中视图的屏幕截图：

删除projecttasks表中的行有效，但返回当前视图还不行。我知道为什么会这样。这是因为我的$ project_id变量在我的ProjectTaskController中没有任何值。但在删除projecttasks表中的行之前，我确实在视图中看到了值。

我将首先向您展示我在浏览器上看到的错误页面：

那对我来说并不清楚，但我确实看到网址看起来很奇怪。因为它有双正斜杠。它看起来像这样：

http://localhost/offerteTool/public/user/projects//edit

我现在会告诉你我曾尝试过的事情：

form.blade.php（查看）：

@foreach ($project->projecttask as $pt)
              <tr>
                <td>
                    {{ $pt->task['task_name'] }}
                </td>
                <td>
                    {{-- {{  $project->id }} --}}
            <input type="hidden" name="projectId" value="{{$project->id}}"/>
                {{--    {{Form::hidden('id', $project->id)}} --}}
                </td>
                <td>
                    {{ Form::text('hour', $pt->hour, array('class' => 'form-control', 'id'=>'hour')) }}
                </td>
                <td>
                    {{ Form::text('hour_salary', $pt->hour_salary, array('class' => 'form-control', 'id'=>'hour_salary')) }}
                </td>
                <td>
                {{ Form::text('total_salary', $pt->total_salary, array('class' => 'form-control', 'id'=>'total_salary', 'disabled')) }}
                {{--    {{ Form::text('total_salary', $project->total_salary, array('class' => 'form-control', 'id'=>'total_salary', 'disabled')) }}--}}
                </td>
                <td>
                    <div class="dropdown">
                        <button type="button" class="btn btn-danger dropdown-toggle selDelete" data-toggle="dropdown">
                            <input id="check1" name="checkbox[]" type="checkbox" class="check" >
                            <span class="caret-hover caret"></span>
                        </button>
                        <ul class="dropdown-menu" aria-labelledby="selDelete" role="menu">
                            <li><a href= "{{ route('user.projecttasks.destroy',array( $pt->id )) }}" data-method="delete" >Delete</a></li>
                        </ul>   
                     </div>
                </td>
              </tr>
            @endforeach

ProjectTasksController.php：

<?php 
public function destroy($id)
{  $project_id=Input::get('projectId');
    //die(print_r($project_id)); //there is no value in $project_id
    Projecttask::destroy($id);

    //$project = Project::find($project_id);
    return Redirect::route('user.projects.edit', array($project_id));

}

然后我们去routes.php：

<?php
Route::group(array('prefix'=>'user', 'before'=>'auth'),function(){
    Route::resource('usergroups', 'UsergroupsController');
    Route::resource('orders', 'OrdersController');
    Route::resource('users', 'UsersController');
    Route::resource('tasks', 'TasksController');
    Route::resource('projects', 'ProjectsController');

    Route::get('orders/destroy/{id}',array('as'=>'user.orders.destroy', 'uses'=>'OrdersController@destroy'));
    Route::get('users/destroy/{id}',array('as'=>'user.users.destroy', 'uses'=>'UsersController@destroy'));
    Route::get('projects/destroy/{id}',array('as'=>'user.projects.destroy', 'uses'=>'ProjectsController@destroy'));
    Route::get('projecttasks/destroy/{id}',array('as'=>'user.projecttasks.destroy', 'uses'=>'ProjectTasksController@destroy'));

    });

然后我们在ProjectsController.php中运行edit（）方法：

public function edit($id)
    {
        $project = Project::find($id);

        return View::make('user.projects.edit', compact('project'));
    }

有人可以帮助我吗？
