Laravel 6 在注册过程中生成用户名
Posted

【中文标题】Laravel 6 在注册过程中生成用户名【英文标题】：Laravel 6 Generate username during registration process 【发布时间】：2021-06-27 18:33:55 【问题描述】：我不知道这是否可行。我创建了一个 Laravel 6 项目并添加了 auth.现在我希望程序在注册过程中生成用户名。用户没有任何输入字段来写他们的用户名。该程序应该自动生成。例如，用户名为“test”，用户名可以是 test12345678。基本上，它将是用户名 + 8 个随机数。这是 register.blade.php

这是 registerController.php:
<?php
namespace App\Http\Controllers\Auth;
use App\Http\Controllers\Controller;
use App\Providers\RouteServiceProvider;
use App\User;
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
| 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'],
]);
/**
* Create a new user instance after a valid registration.
*
* @param array $data
* @return \App\User
*/
protected function create(array $data)
return User::create([
'name' => $data['name'],
'email' => $data['email'],
'password' => Hash::make($data['password']),
'avatar' => 'default.png',
]);
我还在用户表中添加了一个名为“用户名”的新列
【问题讨论】：
您似乎没有在这里尝试解决这个问题？ 【参考方案1】：您可以在RegisterController 的create 方法中将以下内容添加到User::create 调用中。
'username' => $data['name'] . rand(pow(10, 8 - 1), pow(10, 8) -1);
这将采用他们提供的名称并附加 8 个随机数字。
不要忘记将username 添加到User 模型的$fillable 属性中。
protected $fillable = ['name', 'email', 'password', 'avatar', 'username'];

首先感谢您的回答。其次，我尝试添加您的代码，但出现此错误 Illuminate\Database\QueryException SQLSTATE[HY000]: General error: 1364 Field 'username' doesn't have a default value (SQL: insert intousers (name, email，password，updated_at，created_at) 值（测试，test@gmail.com，$2y$10$JjQbZUAziilZgU4voc58XO48q5lKAPWQ1rXlpKLLunttjYTCQ9L9u，2021-013-31 19:32:21-0-26: 26:25))
@ArianKapllanaj 您是否将它添加到了正确的位置，并且是 username 在您的 protected $fillable 数组中的 User 类中？
哦，我的错。是的，它有效！非常感谢！【参考方案2】：
您可以在RegisterController 中执行此操作，如下所示
/**
* Create a new user instance after a valid registration.
*
* @param array $data
* @return \App\User
*/
protected function create(array $data)
return User::create([
'name' => $data['name'],
'email' => $data['email'],
'password' => Hash::make($data['password']),
'username' => $data['name'] . str_pad(mt_rand(1,99999999),8,'0',STR_PAD_LEFT)
'avatar' => 'default.png',
]);

您好，谢谢您的回答。我将您的代码添加到我的项目中并收到此错误 Illuminate\Database\QueryException SQLSTATE[HY000]: General error: 1364 Field 'username' doesn't have a default value (SQL: insert intousers (name, @ 987654325@，password，updated_at，created_at) 值（测试，test@gmail.com，$2y$10$wPMp5ydeTP4hjUal0IUTPeglOPKG1ObwXfRcwU7WIYH5cmLDuJmUW，2021-03-11，2021-03-11，2021-03-31 19:3-34: :41))以上是关于Laravel 6 在注册过程中生成用户名的主要内容，如果未能解决你的问题，请参考以下文章
