【中文标题】SQLSTATE [23000]：违反完整性限制：1062 \'mail@mail.com\' \'users_email_unique\' 键的重复条目【英文标题】：SQLSTATE [23000]: Integrity limitation violation: 1062 'mail@mail.com' duplicate entry for 'users_email_unique' keySQLSTATE [23000]：违反完整性限制：1062 'mail@mail.com' 'users_email_unique' 键的重复条目 【发布时间】：2020-10-16 17:33:08 【问题描述】：我有一个注册表。当电子邮件在数据库中注册时，它会收到一条错误消息
SQLSTATE [23000]: Violation of integrity restrictions: 1062 Duplicate entry 'mail@mail.com' for 'users_email_unique' key
我想避免这个错误，而是收到类似“注册电子邮件”或类似内容的警告。任何帮助表示赞赏。这是我的代码。

如果邮箱已注册，如何发出通知提醒？
【问题讨论】：
【参考方案1】：你必须像这样使用。从验证中删除unique:users
return Validator::make($data, [
'name' => 'required|min:4',
'id_level' => 'required',
'email' => 'required|min:4|email',
'password' => 'required',
'confirm' => 'required|same:password',
'g-recaptcha-response' => 'required|captcha',
]);

【参考方案2】：您必须在控制器中使用 laravel 验证来验证请求参数。
首先在你的控制器顶部添加这个使用
use Illuminate\Support\Facades\Validator;
然后在你的 registercontroller 中定义这个方法
public function register(Request $request)
$validator = Validator::make($request->all(), [
'email' => 'required|email|unique:users',
'password' => 'required|max:10',
'name' => 'nullable|string|max:50',
]);
if ($validator->fails())
$response = $validator->errors();
session()->flash('flash_error', $response);
return redirect()->back();
/**
* create new user
*/
try
/**
* new user
*/
User::create([
'name' => $request->name,
'email' => $request->email,
'password' => Hash::make($request->password),
]);
catch (Exception $e)
throw new HttpException(500, $e->getMessage());
session()->flash('flash_success', 'you are registered.');
return redirect()->back();
默认情况下，laravel 中的电子邮件字段是唯一的，为了验证它，我们使用此异常：
unique:users
users 是表名。
了解有关 laravel 验证的更多信息
查看此链接 https://laravel.com/docs/7.x/validation
访问视图文件中的验证错误
我们通过名称为flash_error 的错误闪存会话
你可以像这样展示它：
@if(session()->has('flash_error'))
<ul>
@foreach(session()->get('flash_error') as $error)
<li> session()->get('flash_error') </li>
@endforeach
</ul>
@endif
并像这样使用引导程序显示成功消息：
@if(session()->has('flash_success'))
<div class="alert alert-success" role="alert">
session()->get('flash_success')
</div>
@endif
