Laravel 7中的多条件搜索功能

Question

我正在尝试搜索具有下拉值和日期范围的值。但它一次只适用于一个。就像我 select 来自下拉列表的值和 select 日期范围它不显示。

这是我的代码

控制器：

public function sale_index(request $request){

    $users = User::orderBy( 'fname', 'asc')->get();
    $sales = Sim::where('stock', '>', 0)->orderBy( 'id', 'desc')->get();

    if($request->filled('search')){
        $sales = Sim::where('user_id', '=', $request->search)->orderBy( 'id', 'desc')->get();
    }
    if($request->filled('from') AND $request->filled('to')){
        $sales = Sim::whereBetween('created_at', [$request->get('from'), $request->get('to')])->orderBy( 'id', 'desc')->get();
    }

    return view('admin.all_sale', compact('sales','users'));
}

Blade 文件:

  <form action="" method="GET">
        <select name="search" id="">
            <option value="">Seller Name</option>
            @foreach ( $users as  $row)
              <option value="{{ $row->id }}" @if ($row->id == request()->query('search'))
                selected
                @else
              @endif >{{ $row->fname }} {{ $row->lname }}</option>
            @endforeach
        </select>
        <input type="date" name="from">
        <input type="date" name="to">
        <button type="submit">Search</button>
      </form>

请帮我解决这个问题

这两个条件被不同的查询覆盖，而不是将 where 过滤器全部合并为一个查询。

尝试改变这个：

$sales = Sim::where('stock', '>', 0)->orderBy( 'id', 'desc')->get();

if($request->filled('search')){
    $sales = Sim::where('user_id', '=', $request->search)->orderBy( 'id', 'desc');
}
if($request->filled('from') AND $request->filled('to')){
    $sales = Sim::whereBetween('created_at', [$request->get('from'), $request->get('to')])->orderBy( 'id', 'desc');
}

为此：（更改将 $sales = 替换为 $sales-> 到 where 子句）

$sales = Sim::where('stock', '>', 0)->orderBy( 'id', 'desc');

if($request->filled('search')){
    $sales->orWhere('user_id', '=', $request->search)->orderBy( 'id', 'desc');
}
if($request->filled('from') AND $request->filled('to')){
    $sales->orWhereBetween('created_at', [$request->get('from'), $request->get('to')])->orderBy( 'id', 'desc');
}

$sales->get();
