Question

I am working on a project and here are the fields touched
users table-
<?php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
class CreateUsersTable extends Migration
{
/**
* Run the migrations.
*
* #return void
*/
public function up()
{
Schema::create('users', function (Blueprint $table) {
$table->bigIncrements('id');
$table->string('name');
$table->string('email')->unique();
$table->timestamp('email_verified_at')->nullable();
$table->string('password');
$table->rememberToken();
$table->unsignedInteger('role_id');
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* #return void
*/
public function down()
{
Schema::dropIfExists('users');
}
}
role table-
<?php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
class CreateRolesTable extends Migration
{
/**
* Run the migrations.
*
* #return void
*/
public function up()
{
Schema::create('roles', function (Blueprint $table) {
$table->bigIncrements('id');
$table->string('description');
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* #return void
*/
public function down()
{
Schema::dropIfExists('roles');
}
}
user model
<?php
namespace App;
use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;
class User extends Authenticatable
{
use Notifiable;
/**
* The attributes that are mass assignable.
*
* #var array
*/
protected $fillable = [
'name', 'email', 'password', 'role_id',
];
public function role(){
return $this->belongsTo(Role::class);
}
/**
* The attributes that should be hidden for arrays.
*
* #var array
*/
protected $hidden = [
'password', 'remember_token',
];
/**
* The attributes that should be cast to native types.
*
* #var array
*/
protected $casts = [
'email_verified_at' => 'datetime',
];
}
Role model
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Role extends Model
{
protected $guarded = [];
public function users(){
return $this->hasMany(User::class);
}
}
register controller
<?php
namespace App\Http\Controllers\Auth;
use App\Http\Controllers\Controller;
use App\Role;
use App\User;
use Illuminate\Foundation\Auth\RegistersUsers;
use Illuminate\Support\Facades\Hash;
use Illuminate\Support\Facades\Validator;
class RegisterController extends Controller
{
/*

*/
use RegistersUsers;
/**
* Where to redirect users after registration.
*
* #var string
*/
protected $redirectTo = '/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'],
'role_id' => 'required',
]);
}
/**

*/
protected function create(array $data)
{
$user = User::create([
'name' => $data['name'],
'email' => $data['email'],
'password' => Hash::make($data['password']),
'role_id' => $data['role_id'],
]);
$roles = Role::all();
return compact('user', 'roles');
}

I am getting this error:
Undefined variable: roles (View: /Users/macair13/MeatracProject/resources/views/auth/register.blade.php)
and I have declared roles in my register controller
Please cloud you help me because personally, I am lost

Answer 1

You haven't passed $roles variable in your blade file,
So, fatal error occurs in foreach loop of your blade file,
so to resolve this you have to pass $roles in your blade ,
There many methods to pass $roles to register.blade file.
by override showRegistrationForm() method from below path in your controller
\vendor\laravel\framework\src\Illuminate\Foundation\Auth\RegistersUsers.php
or pass $roles in method inside above vendor path.
for example:
return view('auth.register')->with($roles,Role::get());//don't forget to use Role model.
Or incase if your $roles is not set use isset() condition before your foreach() in blade file like
#isset($roles)
#foreach($roles as $role)
<option value="{{ $role->id }}">{{ $role->name }}</option>
#endforeach
#endisset

Answer 2

You need to pass the roles to the view, but what you did is when the user is being created, you try to return the roles. They are not needed then.
So just override the showRegistrationForm() method within your register controller, and it should work.
Add this in your RegisterController.
public function showRegistrationForm()
{
$roles = Role::all();
return view('auth.register', compact('roles'));
}
and this:
protected function create(array $data)
{
$user = User::create([
'name' => $data['name'],
'email' => $data['email'],
'password' => Hash::make($data['password']),
'role_id' => $data['role_id'],
]);
$roles = Role::all();
return compact('user', 'roles');
}
Should be this:
protected function create(array $data)
{
return User::create([
'name' => $data['name'],
'email' => $data['email'],
'password' => Hash::make($data['password']),
'role_id' => $data['role_id'],
]);
}
