Question

我创建了一个搜索数据表的列，但是我不知道如何使用CRUD操作添加Action列。

这是我的刀片：users.blade.php。我没有发送html部分，因为我没有发现任何困难。

<script type="text/javascript">
$(document).ready(function(){

 fetch_data();

 function fetch_data(department = '')
 {
  $('#users_table').DataTable({
   processing: true,
   serverSide: true,
   ajax: {
    url:"{{ route('users.index') }}",
    data: {department:department}
   },
   columns:[
    {
     data: 'id',
     name: 'id'
    },
    {
     data: 'name',
     name: 'name'
    },
    {
     data: 'deptName',
     name: 'deptName',
     orderable: false
    },
    {
     data:'email',
     name:'email'
    },
    {
      data: 'action', 
      name: 'action', 
      orderable: false, 
      searchable: false
      }    
   ]
  });
 }
</script>

这是我的控制器：UsersController。请提供帮助，因为它确实很重要。

function index(Request $request)
    {
     if(request()->ajax())
     {
      if($request->department)
      {
       $data = DB::table('users')
         ->join('department', 'department.deptName', '=', 'users.department')
         ->select('users.id', 'users.name', 'users.email', 'department.deptName')
         ->where('users.department', $request->department);
      }
      else
      {
       $data = DB::table('users')
         ->join('department', 'department.deptName', '=', 'users.department')
         ->select('users.id', 'users.name', 'users.email', 'department.deptName');
      }

      return datatables()->of($data)->make(true);

      }


         $department = DB::table('department')
         ->select("*")
         ->get();

      return view('users', compact('department'));


      $data = User::latest()->get();
            return Datatables::of($data)
                    ->addIndexColumn()
                    ->addColumn('action', function($row){

                           $btn = '<a href="javascript:void(0)" class="edit btn btn-primary btn-sm">Read</a>';

                            return $btn;
                    })
                    ->rawColumns(['action'])
                    ->make(true);
         }

您正在使用ajax数据表，我将用代码更新它，它可以正确使用过滤器并在laravel中搜索完全可自定义的服务器端代码以查找ajax数据表

请不要忘记包括数据表库和其他与数据表相关的

docker run -it --rm -p 8888:8080 <imageid or image name>

然后在您的控制器中为此添加两个操作

in your routes/web.php

Route::any('/admin/viewallregisteredusers', 'FrontusersController@viewAllRegisteredClients');
    Route::any('/admin/viewallusers_datatable', 'FrontusersController@getAllUsers');

和

public function viewAllRegisteredClients(){
        return view('frontusers.viewallusers');
    }

您的视图文件如下所示

public function getAllUsers(Request $request){
            $columns = array(
                0 => 'id',
                1 => 'user_name',
                2 => 'user_email',
                3 => 'user_type',
                4 => 'created_at',
                5 => 'updated_at',
            );
            $limit = $request->input('length');
            $start = $request->input('start');
            $order = $columns[$request->input('order.0.column')];
            $dir = $request->input('order.0.dir');
            $query = new Frontuser();
            $totalTitles = $query->count();
            if (empty($request->input('search.value'))) {
                    $titles = Frontuser::select('id','user_name','user_email','user_type','created_at','updated_at')->offset($start)
                      ->limit($limit)
                      ->orderBy($order, $dir)
                      ->get();
                    $totalFiltered = $totalTitles;
                     $data = array();
            }else{
                    $search = $request->input('search.value');
                    $titless = Frontuser::where(function ($q) use ($search)
                    {
                        $q->where('user_name', 'LIKE', "%{$search}%")
                        ->orWhere('user_email', 'LIKE', "{$search}%")
                        ->orWhere('user_type', 'LIKE', "{$search}%")
                        ->orWhere('created_at', 'LIKE', "{$search}%");
                    });
                    $titles = $titless->offset($start)
                       ->limit($limit)
                       ->orderBy($order, $dir)
                       ->get();
                    $totalFiltered = Frontuser::where(function ($q) use ($search)
                    {
                        $q->where('user_name', 'LIKE', "%{$search}%")
                        ->orWhere('user_email', 'LIKE', "{$search}%")
                        ->orWhere('user_type', 'LIKE', "{$search}%")
                        ->orWhere('created_at', 'LIKE', "{$search}%");
                    })->count();
            }

            if (!empty($titles)) {
                 $data = array();
                 $count = 1;
                 foreach ($titles as $title) {
                    $id= base64_encode(serialize($title->id));
                        $nestedData['sno'] = $count;
                        $nestedData['user_name'] = ucfirst($title->user_name);
                        $nestedData['user_email'] = $title->user_email;
                        $nestedData['user_type'] = $title->user_type;
                        $nestedData['created_at'] = date('d-m-Y', strtotime($title->created_at));
                        $nestedData['updated_at'] = '<div class="dropdown">
                                                      <button class="btn btn-primary dropdown-toggle" type="button" data-toggle="dropdown">Actions

                                                        <li><a href='.action("FrontusersController@adminChangeUserPassword",$id).'>Change Password</a></li>
                                                      </ul>
                                                    </div>';
                        $data[] = $nestedData;
                        $count++;
                 }
            }
            $json_data = array(
                "draw" => intval($request->input('draw')),
                "recordsTotal" => intval($totalTitles),
                "recordsFiltered" => intval($totalFiltered),
                "data" => $data,
            );
            echo json_encode($json_data);
    }

您可以根据需要进行修改
