php - LARAVEL：我想从另一个表中导入信息并将其添加到注册表单

问题描述

我创建了一个新的数据库部门，其中包含两行（id、name）。我想从数据库中导入信息并将其放入注册表单的下拉列表中

正如您从下面的代码中看到的那样，我在register.blade.php

<div class="form-group-row">
    <label for="departements" class="col-md-4 control-label text-md-right">Départements :</label>
    <div class="col-md-6">
        <select name="departements" id="departements" class="form-control">
            @foreach($departements as $departement)
                <option value="{{ $departement ->id }}">{{ $departement ->name }}</option>
            @endforeach
       </select>
    </div>
</div>

我已经设置了用户和部门之间的关系。部门型号：

class Departement extends Model
{
    public $fillable = ['name'];
    public function users()
    {
        return $this->belongsToMany('App\User');
    }
}

用户型号：

public function departements()
{
    return $this->belongsToMany('App\Departement');
}
public function HasAnydepartement($departements)
{
    if($this—&gt;departements()->whereIn('name',$departements)->first())
    {
        return true;
    }
    return false;
}
public function Hasdepartement($departement)
{
    if($this->departements()->where('name',$departement)->first())
    {
        return true;
    }
    return false;
}

我App\Departement在寄存器控制器上使用了。

我的问题是，即使我使用了App\Departement他们也向我展示了这个错误：

未定义变量：departements（查看：C:\Users\tchic\AppData\Roaming\Composer\vendor\bin\anapec\resources\views\auth\register.blade.php）

这是我的注册控制器，我有错误：

<?php

namespace App\Http\Controllers\Auth;

use App\Http\Controllers\Controller;
use App\Providers\RouteServiceProvider;
use App\User;
use App\Departement;
use Illuminate\Foundation\Auth\RegistersUsers;
use Illuminate\Support\Facades\Hash;
use Illuminate\Support\Facades\Validator;

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

    |
    */

    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)
    {
        $departements=Departement::all();
        return Validator::make($data, [
            'name' => ['required', 'string', 'max:255'],
            'prenom' => ['required', 'string', 'max:255'],
            'phone' => ['required', 'string', 'max:255'],
            'email' => ['required', 'string', 'email', 'max:255', 'unique:users'],
            'password' => ['required', 'string', 'min:8', 'confirmed'],
        ]);
    }

    /**
     * Create a new user instance after a valid registration.
     *
     * @param  array  $data
     * @return \App\User
     * @return \App\Departement
     */
    protected function create(array $data)
    {
        $departements=Departement::all();
        return User::create([
            'name' => $data['name'],
            'prenom' => $data['prenom'],
            'phone' => $data['phone'],
            'departement' => $data['departement'],
            'email' => $data['email'],
            'password' => Hash::make($data['password']),
        ]);
    }
}

如果有人可以帮助我了解我可以在 Register 控制器上定义 departements 变量的位置，那将很有帮助。谢谢你。
