Question

在控制器中

public function store(Request $req)
{
    $req->validate([
    'username' => 'required|unique:users',
    ]);

    $users = new Users();
    $users->username = $req->username;
    $users->save();        
    return redirect()->route('list.users');
}

用户名验证返回为The username has already been taken.

我将用户名字段键入为JHON，我将返回验证，例如：The JHON has already been taken.？

Answer 1

我相信您可以在定义自定义验证消息时使用:input。

public function store(Request $req)
{
    Validator::make($req, [
        'username' => 'required|unique:users',
    ], [
        'unique' => 'The :input username has already been taken.',
    ]);

    $users = new Users();
    $users->username = $req->username;
    $users->save();        
    return redirect()->route('list.users');
}

要使代码更整洁，应更改“唯一”验证错误的本地化

转到文件“ resources / lang / en / validation.php”（或使用您的语言的iso代码更改“ en”部分）并更改“唯一”值。

发件人：

'unique' => 'The :attribute has already been taken.',

收件人：

'unique' => 'The :attribute :input has already been taken.',

这样，您应该会收到以下消息

用户名JHON已被占用。

Answer 3

$req->validate([
    'username' => 'required|unique:users,username',
    ]);

这是使用唯一性的语法：

unique:table,column

如何使用输入值作为名称自定义验证？
