Question

以下是我的问题：

return App\AftermarketParts::where('alt', 'LIKE', "%$search%")
        ->orderBy('alt',"$direction")
        ->with('aftermarket_parts_type')
        ->get()
        ->groupBy('aftermarket_parts_type_id');

以下是我的数据集：

(16) [{…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}, {…}]
0:alt:(...)
  created_at:(...)
  deleted_at:(...)
  id:(...)
  image:(...)
  image_height:(...)
  image_width:(...)
  link:(...)
  tires_and_rims_type:Object
    created_at:(...)
    deleted_at:(...)
    description:(...)
    id:(...)
    name:(...)
    updated_at:(...)
1:{…}
2:{…}

我正在尝试按名称对结果进行排序，当然这不起作用。

return App\AftermarketParts::where('alt', 'LIKE', "%$search%")
            ->orderBy('alt',"$direction")
            ->orderBy('name',"$name_direction")
            ->with('aftermarket_parts_type')
            ->get()
            ->groupBy('aftermarket_parts_type_id');

我也尝试过：

return DB::table('aftermarket_parts')
    ->join('aftermarket_parts_categories','aftermarket_parts_categories.id','=','aftermarket_parts.aftermarket_parts_type_id')
    ->select(DB::raw(
        'aftermarket_parts.id,
        aftermarket_parts.link,
        aftermarket_parts.image,
        aftermarket_parts.webpage_screen_shot,
        aftermarket_parts.alt,
        aftermarket_parts.image_width,
        aftermarket_parts.image_height,
        aftermarket_parts.aftermarket_parts_type_id,
        aftermarket_parts.deleted_at,
        aftermarket_parts.created_at,
        aftermarket_parts.updated_at'))
    ->groupBy('name')
    ->orderBy('aftermarket_parts.alt', "$direction")
    ->orderBy('name', "$groupDirection")
    ->get();

返回DataSet：

data:Array(80)
  0:
    aftermarket_parts_type_id:(...)
    alt:(...)
    created_at:(...)
    deleted_at:(...)
    id:(...)
    image:(...)
    image_height:(...)
    image_width:(...)
    link:(...)
    updated_at:(...)
    webpage_screen_shot:(...)

即使它正确地返回了命令，它也会以我需要它的格式销毁对象数组。我想知道是否有办法通过雄辩的调用来完成这个或者我应该只使用php排序数组？想法？提前谢谢。

Answer 1

我能想到的唯一解决方案是在不使用eloquent或sql的情况下反转数组顺序。它简单而且有效。

$AftermarketParts = App\AftermarketParts::where([
            ['alt', 'LIKE', "%$search%"]
        ])
        ->orderBy('alt',"$direction")
        ->with('aftermarket_parts_type')
        ->get()
        ->groupBy('aftermarket_parts_type_id');

    $temp = [];
    $j = 0;
    for ($i=count($AftermarketParts); $i > 0; $i--) {
        $temp[$j] = $AftermarketParts[$i];
        $j++;
    }
    return $temp;

最后一个解决方案颠倒了数组的顺序，这个数组使用冒泡排序对数组进行排序。

function bubbleSort($Array) {
    $lastPos = count($Array);
    for($lastPos -1; $lastPos >= 1; $lastPos--) {
        for($i = 1; $i <= $lastPos -1; $i++) {
            if($Array[$i][0]->aftermarket_parts_type->name > $Array[$i+1][0]->aftermarket_parts_type->name) {
                $temp = $Array[$i];
                $Array[$i] = $Array[$i+1];
                $Array[$i+1] = $temp;
            }
        }
    }
    return $Array;
}

Laravel Eloquent按元素排序
