如何从 Laravel 的控制器中获取条件数据

Question

我有两个表“用户”和“预测”，用户表有两列“Org1”和“Org2”，预测表“CurrOg1”和“CurrOrg2”中有相同的列。当用户注册时，他必须从下拉列表中选择“Org1”和“Org2”，并将选定的值分配给用户。现在我想检查用户表中的“Org1”和“Org2”值以及登录到应用程序的当前用户的预测表。例如，如果用户“Org1”在注册时存储为“abc”，他必须只能查看“CurrOrg”为“abc”的数据，对于“Org2”也是如此。 当我尝试获取结果时出现数据表错误。

这是我的注册控制器和查看代码：

class RegisterController extends Controller
{
    /*
    |--------------------------------------------------------------------------
    | Register Controller
    |--------------------------------------------------------------------------
    |
    | This controller handles the registration of new users as well as their
    | validation and creation. By default this controller uses a trait to
    | provide this functionality without requiring any additional code.
    |
    */

    use RegistersUsers;

    /**
     * Where to redirect users after registration.
     *
     * @var string
     */

    protected $redirectTo = RouteServiceProvider::HOME;

    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('guest');
    }

    /**
     * Get a validator for an incoming registration request.
     *
     * @param  array  $data
     * @return \Illuminate\Contracts\Validation\Validator
     */
    protected function validator(array $data)
    {
        return Validator::make($data, [
            'name' => ['required', 'string', 'max:255'],
            'email' => ['required', 'string', 'email', 'max:255', 'unique:users'],
            'password' => ['required', 'string', 'min:8', 'confirmed'],
            'Org1' => [ 'string'],
            'Org2' => ['string'],
        ]);
    }

    /**
     * Create a new user instance after a valid registration.
     *
     * @param  array  $data
     * @return \App\Models\User
     */
    protected function create(array $data)
    {
        return User::create([
            'name' => $data['name'],
            'email' => $data['email'],
            'password' => Hash::make($data['password']),
            'Org1' => $data['Org1'],
            'Org2' => $data['Org2'],
        ]);
        Mail::to($data['email'])->send(new WelcomeMail($user));

        return $user;
    }

    public function showRegistrationForm()
    {
        $Org1_list = DB::table('predictions')
                            ->select('CurrOrg1')
                            ->groupBy('CurrOrg1')
                            ->orderBy('CurrOrg1', 'ASC')
                            ->get();
        $Org2_list = DB::table('predictions')
                            ->select('CurrOrg2')
                            ->groupBy('CurrOrg2')
                            ->orderBy('CurrOrg2', 'ASC')
                            ->get();

        return view('auth.register', compact('Org1_list','Org2_list'));
    }
}

注册查看：

<div class="form-group row">
                            <label for="Org1" class="col-md-4 col-form-label text-md-right">Org1</label>

                            <div class="col-md-6">
                                <select class="form-control" name="Org1" id="Org1">
                                    <option value="">Select Org1</option>
                                    @foreach($Org1_list as $use)
                                    @if(!empty($use))
                                    <option value="{{$use->CurrOrg1}}">{{$use->CurrOrg1}}</option>
                                    @endif
                                    @endforeach
                                </select>

                                @error('Org1')
                                    <span class="invalid-feedback" role="alert">
                                        <strong>{{ $message }}</strong>
                                    </span>
                                @enderror
                            </div>
                        </div>

                        <div class="form-group row">
                            <label for="Org2" class="col-md-4 col-form-label text-md-right">Org2</label>

                            <div class="col-md-6">
                                <select class="form-control" name="Org2" id="Org2">
                                    <option value="">Select Org2</option>
                                    @foreach($Org2_list as $use)
                                    @if(!empty($use))
                                    <option value="{{$use->CurrOrg2}}">{{$use->CurrOrg2}}</option>
                                    @endif
                                    @endforeach
                                </select>

                                @error('Org2')
                                    <span class="invalid-feedback" role="alert">
                                        <strong>{{ $message }}</strong>
                                    </span>
                                @enderror
                            </div>
                        </div>

这是我的预测控制器：

{
                $user=DB:: table('users')
                      ->select('id','Org1','Org2','email')
                      ->get();

                if($CurrOrg1 == $user->Org1 && Auth::user()->email == $user->email)
                { 

                        $data = DB:: table('predictions')
                        ->select('id','EmployeeNumber','Role','Region','CurrOrg1','CurrOrg2','RiskZone','Probablity','Rating','Feedback','Gender','CurrOrg3','CurrOrg4','CurrOrg5','ProfessionalClassification','Local_Expat','EmployeeRoleSeniority','FeedRisklevel','Feedinfluencers','Action','Fname','Lname','Avgweekhr')
                        ->get();
                }
            }
            return datatables()->of($data)
            ->addColumn('Feedback', function($data)
            {   
                if($data->Action == 'No')
                {
                return "<a href='#' style='background-color:#CA0088;color:#fff' class='btn btn-sm Feedback' id='".$data->id."'>Feedback</a>";
                }
                else
                   {
                     return "<a href='#' style='background-color:#00A300;color:#fff' class='btn btn-sm Feedback' id='".$data->id."'>Feedback</a>";
                   } 
            })
            ->escapeColumns([])
            ->make(true);
        }

这是我加载数据的方式：

$(document).ready(function(){

    fill_datatable();

    function fill_datatable(BusinessUnit = '', CurrOrg1 = '', CurrOrg2 = '', Role = '', Region = '' , Gender = '', CurrOrg3 = '' , CurrOrg4 = '', CurrOrg5 = '', ProfessionalClassification = '')
    {
        var dataTable = $('#members_data').DataTable({
            dom: 'Bfrtip',
            buttons: ['excel'],
            processing: true,
            serverSide: false,
            

            ajax:{
                url: "{{ route('Predictions.index') }}",
                data:{BusinessUnit:BusinessUnit,CurrOrg1:CurrOrg1,CurrOrg2:CurrOrg2,Role:Role,Region:Region,Gender:Gender,ProfessionalClassification:ProfessionalClassification,CurrOrg3:CurrOrg3,CurrOrg4:CurrOrg4,CurrOrg5:CurrOrg5}
            },
            
            columns: [
                {
                    data: 'EmployeeNumber',
                        name: 'EmployeeNumber',
                    render:function(data, type, row){
                    //console.log(row)}
                    //return "a"}
                    return "<a href='/detail/"+ row.id +"'>" + row.EmployeeNumber+"</a>"}
                },
                {
                    data:'Fname',
                    name:'Fname'
                },
                {
                    data:'Lname',
                    name:'Lname'
                },
                {
                    data:'Role',
                    name:'Role'
                },
                {
                    data:'Region',
                    name:'Region'
                },
                {
                    data:'CurrOrg1',
                    name:'CurrOrg1'
                },
                {
                    data:'CurrOrg2',
                    name:'CurrOrg2'
                },
});

有人可以建议我在这里做错了什么，或者如何解决上述问题。提前致谢！

Answer 1

将 get() 函数替换为 first() 以匹配条件。

  $user=DB:: table('users')
                  ->select('id','Org1','Org2','email')
                  ->first();
