Laravel PHP 过滤器下拉搜索

Question

需要有关下拉过滤器的帮助。我的任务是分离活跃的、停用的、待批准的等员工。所以我所做的是我创建了一个下拉列表过滤器，以避免为每个状态创建另一个数据 table。请帮我。谢谢！！！

这是控制器

public 函数索引() {

$user = DB::table("user_basic")
->leftjoin("user_status","user_status.status_id" , "=" , "user_basic.user_id")       
->select("user_status.*", "user_basic.*")
->get();
$datatables = datatables::of($user);



return view("pages.Directory.index")->with("user",$user);

}

索引页

@section('css')
@include('layouts.datatables-css')
@endsection
@section('content')

您可以编写查询但从末尾删除 get() 函数。

   $user = DB::table("user_basic")
    ->leftjoin("user_status","user_status.status_id" , "=" , "user_basic.user_id")       
    ->select("user_status.*", "user_basic.*");

然后写这个 if 语句，不要忘记用你的列名自定义我调用 status.name 的列

  if (request()->filled('status') && request('status') !== null) {
        $data = $data->where('status.name', request()->status);
    }

然后路径 $user 到数据表；你会得到结果

$datatables = datatables::of($user);
