Question

对于我写问题的方式，我感到非常抱歉，我不知道该怎么解释我的问题，但希望你能得到我想要的东西；我想展示一个产品及其附加组件，一切正常，但我想将这些附加组件归类到它们的标题下，请查看屏幕截图，您可以清楚地了解我的问题所以我想停止重复类似的标题..我对laravel非常陌生：（

对于桌子：我有：

   class OrderCustomize extends Model
 {
protected $table = "ordercustomizes";

protected $fillable = [

    'customizeproduct_id',
    'userorder_id',
    'product_id'
];

另一个表格：

 class CustomizeProduct extends Model
 {
protected $table = "customizeproducts";

protected $fillable = [

    'customizetitle_id',
    'product_id',
    'selection_type',
    'selection_number',
    'customize_title',
    'customize_price'
];

此表：

 class CustomizeTitle extends Model
 {
protected $table = "customizetitles";

protected $fillable = [
    'name'

];

在控制器中：

$customizeorders = OrderCustomize::where('userorder_id',$order_number)
    ->with('customizeproduct')
    ->get()
    ->groupBy('customizetitle_id');

在OrderCustomize模型中：

public function customizeproduct()
{
  return $this->belongsTo(CustomizeProduct::class);
}

在CustomizeProduct模型中：

public function customizetitle()
{
    return $this->belongsTo(CustomizeTitle::class);
}

在Blade中：

@if(count($customizeorders)>0)
    @foreach ($customizeorders as $customizetitle => $groupCustomizes)
        @foreach($groupCustomizes as $key=>$customize) 
            @if(($userorder->product_id)==($customize->product_id))

               {{$customize->customizeproduct->customizetitle->name}}:
               {{$customize->customizeproduct->customize_title}} .

            @endif
        @endforeach
    @endforeach
@endif

您可以使用以下查询来显示标题：

$customizeorders = OrderCustomize::select( DB::raw ("GROUP_CONCAT(DISTINCT customizetitle_id) as customizetitle_ids") )
                   ->where('userorder_id',$order_number)
                   ->with('customizeproduct')->get();
