搜索多个字段laravel的最佳方式

Question

我尝试使用 8 个字段创建一个搜索函数。我在底部使用这种方式，但它返回任何报价都具有此给定值之一。我想要的是他拥有所有价值的报价。用户可以在他想要的任何字段中搜索什么是最好的方法，而没有很多条件，如果

 public function search(Request $request)
        {
            $hashids = new Hashids();
            $city = $request->city;
            $category = $request->category;
            $type = $request->type;
            $rooms = $request->rooms;
            $minPrice = $request->minPrice;
            $maxPrice = $request->maxPrice;
            $minSpace = $request->minSpace;
            $maxSpace = $request->maxSpace;
            $citySearch = DB::table('offers')->where('city',$city);
            $categorySearch = DB::table('offers')->where('category_id',$category);
            $typeSearch = DB::table('offers')->where('type',$type);
            $roomsSearch = DB::table('offers')->where('rooms',$rooms);
            $priceSearch = DB::table('offers')
                ->whereBetween('price', [$minPrice, $maxPrice]);
            $spaceSearch = DB::table('offers')
                ->whereBetween('space', [$minSpace, $maxSpace]);
            $result_search = $citySearch->union($categorySearch)->union($typeSearch)->union($roomsSearch)->union($priceSearch)->union($spaceSearch)->get();
            $view = View::make('ajax.search',compact('result_search','hashids'))->render();
            return response()->json(['html'=>$view]);
        }

如果您使用此搜索作为过滤可能性的一种方式，您可以采用此方法，只要设置了输入，该方法仅将条件应用于查询。

这也将其归结为一个查询，而不必合并很多查询：

$projects = Project::

when($request->year_from, function($query) use ($request){
    $query->where('delivery_year', '>=', $request->year_from);
})
->when($request->year_to, function($query) use ($request){
    $query->where('delivery_year', '<=', $request->year_to);
})
->when( $request->delivery_month_from, function($query) use ($request){
    $query->where('delivery_month', '>=', $request->delivery_month_from);
})
->when( $request->delivery_month_to, function($query) use ($request){
    $query->where('delivery_month', '<=', $request->delivery_month_to);
})
->when( $request->product_group, function($query) use ($request){
    $query->whereHas('products', function($q) use ($request) {
        $q->whereHas('group', function($qi) use ($request){
            $qi->whereIn('id', $request->product_group);
        });
    });
})
->get();

编辑 whereBetween：

$projects = Project::

when(($minSpace && $maxSpace), function($query) {
    $query->whereBetween('space', [$minSpace, $maxSpace]);
})->get()

这将检查 $minSpace 和 $maxSpace 是否都设置并且大于零（等于 true）
