【问题描述】：

我在页面上有一个表，我可以从数据库中获取数据并将其加载到表中。现在我想在同一页面上创建应用过滤器选项，并且表中的数据应该被过滤帐户以应用过滤器。我是 Laravel 和 php 的新手，所以尝试了多个选项来过滤可以使用 ajax 完成的找到的选项，jquery 也尝试过，但没有运气。 这是我的示例刀片模板，我可以从列中获取不同的值并将其加载到下拉列表中，但我想要做的是单击应用按钮，表下的数据应根据过滤器进行更新。

@section('content')
<div class="content">
<div class="row">
  <div class="col">
    <div class="form-group">
      <label>Business Unit</label>
      <div class="select2-purple">

          @foreach($Business_unit as $bu)
          <option>  $bu->Business_Unit  </option>

                 $d->Orglevel2
            </td>
            <td>

这是我的 Memeberdetails 控制器，它是一个资源控制器

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\Memberdetails;
use App\Models\Attrition_correlators;
class MemberdetailController extends Controller

    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function __construct()
    
        $this->middleware('auth');
    
    public function index()
    
        $Memberdetails= new Memberdetails;
        $Memberdetails_list= $Memberdetails::all();
        $Business_unit = Memberdetails::distinct('Business_Unit')->get(['Business_Unit']);
        $Org_level1 = Memberdetails::distinct('Orglevel1')->get(['Orglevel1']);
        $Org_level2 = Memberdetails::distinct('Orglevel2')->get(['Orglevel2']);
        $Region_select = Memberdetails::distinct('Region')->get(['Region']);
        return view('admin.members.Datapoints',compact('Memberdetails_list','Business_unit','Org_level1','Org_level2','Region_select'));
    

    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    
        //
    

    /**
     * Store a newly created resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    
        //
    

    /**
     * Display the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function show(Memberdetails $Memberdetail)
    
        $Attrition_correlator = Attrition_correlators::all();
        return view('admin.members.Detailspage',compact('Memberdetail','Attrition_correlator'));
    

    /**
     * Show the form for editing the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function edit($id)
    
        //
    

    /**
     * Update the specified resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function update(Request $request, $id)
    
        //
    

    /**
     * Remove the specified resource from storage.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function destroy($id)
    
        //
    
    

这是我的 web.php

Route::resource('/Memberdetails', MemberdetailController::class);

下面是我的迁移

 public function up()
    
        Schema::create('memberdetails', function (Blueprint $table) 
            $table->id();
            $table->string('membersid');
            $table->string('Role');
            $table->string('Orglevel1');
            $table->string('Orglevel2');
            $table->string('Region');
            $table->string('Professional_clas');
            $table->string('Performance');
            $table->string('Probablity');
            $table->string('Riskzone');
            $table->string('Manager');
            $table->string('Topcorrelators');
            $table->string('Local_Expat');
            $table->string('Role_Seniority');
            $table->string('HR_Region');
            $table->string('Gender');
            $table->string('Marital_Status');
            $table->string('Business_Unit');
            $table->string('Total_Working_years');
            $table->timestamps();
        );
    

我想知道我可以做些什么来使过滤器正常工作，以及我怎样才能在业务部门上级联 Orgleve1 和 Orgleve2..这意味着当我选择业务部门相关的 Org 级别 1 和 Orglevel2 时应该填充下拉列表并且过滤器应该。 任何帮助都会真正帮助我 提前致谢！

感谢@tayyab 的帮助....我也尝试过这个，但我的问题是我在一个表中拥有所有数据以及多个业务部门条目和其他条目，除了 memberid 是独特的..我如何为提到的 senario 做到这一点？
