mysql - 如何在 Laravel 中用图像在输入复选框中显示来自 mysql 的数据？

Question

路线:

Route::get('/slider', 'UserController@showTemplete')->name('slider');
Route::post('/slider-choose','UserController@saveTemplete')->name('choose');

我的 Templete 模型:

class Templete extends Model
{
    protected $table='templete';
    public function Users()
    {
        return $this->belongsToMany(Users::class, 'users_templetes', 'user_id', 'templete_id');
    }
}

我的播种机:

public function run()
{
        $names=['temp1', 'temp2'];
        foreach($names as $name){
            $templete = new Templete();
            $templete->name=$name;
            $templete->save();
        }
    }
}

我的 Controller :

public function showTemplete(){
   $templetes= Templete::all();
   return view('defaultLayout.RegisterPageContentChoose', ['templetes'=>$templetes]);
}

public function saveTemplete(Request $request){         
    $templeteId = $request->get('templete');
    $user=Users::find(Auth::id());
    $user->templete=$templete;
    $user->save();
    return view('slider.slider');
}

但是数据没有保存在数据库中!!!这是我的表格:

<form method="post" action="{{route('choose')}}">
    <div class="form-group">
        @foreach($templetes as $templete)
            <div class="col-md-5 pull-right"><label class="btn">
               <img src="/images/free.png" class=" img-responsive img-thumbnail img-check" style= "height: 500px; width: 100%"><input type="checkbox"  name="templetes"  value="{{$templete->id}}" class="hidden" autocomplete="off"></label>             
           </div>           
           <div class="col-md-5 col-md-5-offset-2 pull-left"><label class="btn">
               <img src="/images/moecv2.png" class=" img-responsive img-thumbnail img-check" style= "height: 500px; width: 100%" ><input type="checkbox"  name="templetes"  value="{{$templete->id}}" class="hidden" autocomplete="off"></label>
           </div>
        @endforeach
    </div>
    <button>@lang('login.account_choose_button')</button><br><br>
    <!-- <input type="submit" value="Check Item" class="btn btn-success"> -->           
</form>

显示 4 张图片(重复)需要两张。如何将选中的复选框保存在数据库中以及如何以显示形式显示两个输入/图像？谢谢你

尝试 attach保存关系:

public function saveTemplete(Request $request){         
    $templeteId = $request->get('templete');
    $user=Users::find(Auth::id());
    $user->templete()->attach($templete_id);
    return view('slider.slider');
}
