Question

我正在使用Laravel5.2。目前，当用户登录时，他们被带到页面，此页面是必须显示的表单。我想这样做只有在表格还没有被填写然后展示时才会这样做。

我的表结构如下所示：

User                       Questions
--------------------------------------------
id                            id
name                          q1
email                         q2
password                      q3
                              user_id

我已设法做到这一点，当用户发布表单时，他们的用户ID也会发布到该表单，但我不知道如何检查是否显示此内容。

routes.php文件

Route::get('/', function () {
    return view('welcome');
});

Route::auth();

Route::get('/home', 'HomeController@index');


Route::post('home', function () {
    $userq = new App\Userregq();
    $userq->Q1 = Input::Get('Q1');
    $userq->Q2 = Input::Get('Q2');
    $userq->Q3 = Input::Get('Q3');
    $userq->user_id = Auth::user()->id; 
    $userq->save(); 
    return redirect('level1');
});

这是我的形式：

    <P> Please fill in this questionairre before you start if you have already done just click the next arrow:</p>
    <div id="form_container">

    {!! Form::open(array('url' => 'home'))!!}
     {!!Form::label('Q1','Why have you decided to use this application?')!!}
            {!!Form::textarea('Q1')!!}<br><br>
            {!!Form::label('Q2','What three things would you like to get out of this application?')!!}
            {!!Form::textarea('Q2')!!}<br><br>
            {!!Form::label('Q3','What time constraints do you foresee and how can you plan around them?')!!}
            {!!Form::textarea('Q3')!!}<br><br>
        <input type = "hidden" name = "id" value = "{{Auth::user()->id}}">

            {!!Form::submit('Submit')!!}
        {!! Form::close() 

!!}

更新

我已将此添加到 HomeController

<?php

namespace App\Http\Controllers;

use App\Http\Requests;
use Illuminate\Http\Request;

class HomeController extends Controller
{
    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('auth');
    }

    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {

    $showForm = ! App\Userregq()->whereUserId(Auth::user()->id)->exists();
        //return view('home');
return view('form-view', compact('showForm')); 
    }

}

这是我更新后的表格：

@if($showForm)
<div id="form_container">

{!! Form::open(array('url' => 'home'))!!}
 {!!Form::label('Q1','Why have you decided to use this application?')!!}
        {!!Form::textarea('Q1')!!}<br><br>
        {!!Form::label('Q2','What three things would you like to get out of this application?')!!}
        {!!Form::textarea('Q2')!!}<br><br>
        {!!Form::label('Q3','What time constraints do you foresee and how can you plan around them?')!!}
        {!!Form::textarea('Q3')!!}<br><br>
    <input type = "hidden" name = "id" value = "{{Auth::user()->id}}">

        {!!Form::submit('Submit')!!}
    {!! Form::close() !!}
@endif

Answer 1

我会在表格中创建一个新列，例如questionairre_filled，这是一个布尔值。因此，如果用户已回答所有问题，请将questionairre_filled设置为1 / true，然后使用中间件进行检查。

如果它失败，中间件将重定向到带有Questionairre表单的页面。

中间件看起来像这样

<?php

namespace App\Http\Middleware;

use Closure;

class QuestionairreMiddleware
{
    /**
     * Run the request filter.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @param  string  $role
     * @return mixed
     */
    public function handle($request, Closure $next, $role)
    {
        if (! $request->user()->questionairre_filled) {
            redirect to the form page
        }

        // If true redirect to the page without the forms
        return $next($request);
    }

}

Answer 2

在不了解模型关系如何工作的情况下，最简单的解决方案是检查表中是否已存在当前用户ID。就个人而言，我更喜欢将此信息放在控制器中并将其作为变量加载。这是一个例子：

// controller
$showForm = ! App\Userregq::whereUserId(Auth::user()->id)->exists();
return view('form-view', compact('showForm'));

// form
@if ($showForm)
    // show the form here
@endif

请注意，这只是一个例子。您可能需要检查用户是否已登录，您可能希望通过模型关系等来执行此操作。

您可以在User模型中指定Userregq的关系，检查控制器的Question表中是否有记录。

用户模型：

Class User extends Model{
    // ...

    public function userregq(){
        return $this->hasOne('App\Userregq');
    }

}

<强> HomeController中：

Class HomeController extends Controller{

    public function index(){
        if (!Auth::user()->userregq){
            // User didn't answer to the questions
        }
        else{
            // User answered to the questions
        }

    }

}

如果用户尚未填写表单，我该如何才能显示表单？
