Laravel 5.3注册后获取最后一个插入ID

Question

Using laravel5.3 php 5.6.3

I want the last inserted id in users table for the redirected page after registration

So I want the last inserted id to userprofileadd.blade.php

I have also tried ->with('id', $user->id) from register function

I don't want automatic login after registration , so I removed the login part , and after registration the user will be redirected to another form , and i want the latest user id (who ever registered) from users table

Register controller:

<?php

namespace App\Http\Controllers\Auth;

use App\User;
use App\role;
use App\Userdetails;

use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Validator;
use Illuminate\Foundation\Auth\RegistersUsers;

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 = '/userprofileadd';

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

    /**
     * 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, [

            'email' => 'required|email|max:255|unique:users',
            'password' => 'required|min:6|confirmed',
            'role'=>'required'
        ]);
    }

    /**
     * Create a new user instance after a valid registration.
     *
     * @param  array  $data
     * @return User
     */
    protected function create(array $data)
    {
        return User::create([

            'email' => $data['email'],
            'password' => bcrypt($data['password']),
            'role_id'=>$data['role'],
        ]);
    }

    public function showregistrationform()
    {
        $roles = role::all(); // get all teams
    return view('auth.register', [ 'roles' => $roles]);
    }
}

register function (i have commented out login after registration)

 public function register(Request $request)
    {
        $this->validator($request->all())->validate();

        event(new Registered($user = $this->create($request->all())));

       // $this->guard()->login($user);

        return $this->registered($request, $user)
            ?: redirect($this->redirectPath());
            // ->with('id', $user->id)
    }

Answer 1

if you are using model then

$user = new User();
$user->name = "JOHN";
$user->save();
$user->id; // contain the inserted id

if you are using db class

$id = DB::table('users')->insertGetId(
   ['email' => 'john@example.com', 'votes' => 0]
);

Answer 2

To get the last created user

$user = User::create([

    'email' => $data['email'],
    'password' => bcrypt($data['password']),
    'role_id'=>$data['role'],
]);

$this->lastCreatedUserId = $user->id;

To pass the userId to custom redirection page

You may use the Laravel Auth redirectTo method . Doc .

protected function redirectTo()
{
    return route('customroutename', ['id' => $this->lastCreatedUserId]);
}

Example:

<?php

namespace App\Http\Controllers\Auth;

use App\User;
use App\role;
use App\Userdetails;

use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Validator;
use Illuminate\Foundation\Auth\RegistersUsers;

class RegisterController extends Controller
{
    public $lastCreatedUser;

    use RegistersUsers;

    protected $redirectTo = '/userprofileadd';

    //The redirectTo method will take precedence over the redirectTo attribute.
    protected function redirectTo()
    {
        //assuming your route name is 'userprofileadd' if not, use your route name of the route('/userprofileadd')
        return route('userprofileadd', ['id' => $this->lastCreatedUser]);
    }

    public function __construct()
    {
        $this->middleware(['auth', 'hr']);
    }

    protected function validator(array $data)
    {
        return Validator::make($data, [

            'email' => 'required|email|max:255|unique:users',
            'password' => 'required|min:6|confirmed',
            'role'=>'required'
        ]);
    }

    protected function create(array $data)
    {
        $user = User::create([

            'email' => $data['email'],
            'password' => bcrypt($data['password']),
            'role_id'=>$data['role'],
        ]);

        $this->lastCreatedUser = $user->id;
        return $user;
    }

    public function showregistrationform()
    {
        $roles = role::all(); // get all teams
    return view('auth.register', [ 'roles' => $roles]);
    }
}

You can access the last created user in your UserprofileController's index method like,

public function index($id)
{
    $lastCreatedUser = $id;
    //you may pass this variable to the view
}

Hope it helps.. Let me know the results..

I'm not sure if this is what you're looking for or not, but you can do this to retrieve the latest record in the users table:

$latestUser = App\User::latest()->first();

Hopefully this helps.
