Laravel - 按升序和降序排列记录

Question

我的控制器中有一个创建方法

public function create()
{
$image = PropertyUser::where('user_id', '=', Auth::user()->id)->get();
foreach($image as $property)
{
    $id = $property->property_id;
}
$image_main = Image::where('property_id', $id)->get();
return view('settings.photos', ['image_array' => $image_main]);
}

这是我的 photos.blade 文件

<form name="asc" action="{{route("settings.photos")}}" method="post" class="text-center">
    @csrf
    <input type="submit"  value="Ascending " class="settings-photos-header2 text-center"/>  |
</form><form name="dec" action="{{route("settings.photos")}}" method="post"  class="text-center">
    @csrf
    <input type="submit"  value= " Descending" class="settings-photos-header2 text-center"/>
</form>
<h2 class="settings-photos-header2 text-center">Photo Gallery</h2>
@foreach ($image_array as $images)
    <div class="image-warp"><img src="{{$images->filename}}"
                                 style="width:100px;height:100px;"><br/><span style="color: #1b1e21">{{$images->description}}</span>
    </form>
    </div>
    @endforeach

问题-我怎样才能让 asc 按钮按升序和 des 降序对图像进行排序，有没有办法将它连接到我的控制器，或者有没有办法通过任何方式按升序和降序对它们进行排序其他方式？

有很多方法可以解决排序问题，但是当您设置好页面后，让我告诉您排序记录的方法。创建另一个指向您的 settings.photos 路由的操作

public function settings_photos($property_id) {

  $form = Input::get('submit');
  $orderBy = $form == "Ascending" ? "asc" : "desc";

  # Fetch Images in of Specific Property 
  $list_of_images = Image::where('property_id', $property_id) 
  # Order by Asc/Desc 
  ->sortBy('id', $orderBy)->get(); 

  return view('settings.photos', ['image_array' => $list_of_images]); } 

现在添加Image->id 以通过表单传入您的控制器操作

https://stackoverflow.com/questions/50432659/laravel-arranging-records-in-ascending-and-descending-order#

<form name="asc" action="{{route("settings.photos")}}" method="post" class="text-center">

  @csrf
    
  <input type="image_id" value="{{$id}}" />
  <input type="submit" value="Ascending " class="settings-photos-header2 text-center"/>  |
</form>

<form name="dec" action="{{route("settings.photos")}}" method="post"  class="text-center">
    @csrf
  <input type="image_id" value="{{$id}}" />
  <input type="submit" value="Descending" class="settings-photos-header2 text-center"/>
</form>

现在对您之前的控制器代码进行一些更改

public function create()
{
$image = PropertyUser::where('user_id', '=', Auth::user()->id)->get();
foreach($image as $property)
{
    $id = $property->property_id;
}
$image_main = Image::where('property_id', $id)->get();
return view('settings.photos', ['image_array' => $image_main, 'id' => $id]);
}

正如我告诉您的，即使通过 Ajax 也有多种方法可以对记录进行排序，但我建议您使用您的代码示例。我也没有优化代码。

如果您有任何问题，请告诉我。 谢谢
