javascript - 在引导模式的不同选项卡上显示 laravel 身份验证错误

Question

我在 bootstrap modal 中实现了 Laravel Auth，bootstrap modal 有 2 个选项卡，一个用于登录，一个用于注册。

在注册选项卡上:用户通过唯一的用户名和电子邮件注册，当单击注册按钮后电子邮件或用户名已经存在时，我想在注册选项卡上显示错误。它向我显示该错误，但该错误显示在登录选项卡上而不是注册选项卡上。

这是我的代码:

<div class="modal-tab-section wd-modal-tabs">
  <ul class="nav nav-tabs wd-modal-tab-menu text-center" role="tablist">
     <li class="nav-item">
        <a class="nav-link active" id="login-tab" data-toggle="tab" href="#login" role="tab" aria-controls="login" aria-expanded="true">Prihlásiť sa</a>
     </li>
     <li class="nav-item">
        <a class="nav-link" id="sign-up-tab" data-toggle="tab" href="#sign-up" role="tab" aria-controls="sign-up">Zaregistrovať sa</a>
     </li>
  </ul>

当 laravel 在验证后在注册 Controller 中检查它时，会出现错误。

Prihlásiť sa 表示登录

Zaregistrovať sa 表示注册

是登录/注册模式的图像

是我在注册选项卡的另一个选项卡上想要的错误:

您可以为此使用命名错误包。

来自 docs :

If you have multiple forms on a single page, you may wish to name the MessageBag of errors, allowing you to retrieve the error messages for a specific form. Pass a name as the second argument to withErrors:

return redirect('register')->withErrors($validator, 'login');

You may then access the named MessageBag instance from the $errors variable:

{{ $errors->login->first('email') }}

添加错误包后，您可以使用如下内容显示正确的选项卡:

<div id="login"
     class="tab-pane fade @if($errors->register->isEmpty()) show active @endif">
...
</div>

<div id="register"
     class="tab-pane fade @if(! $errors->register->isEmpty()) show active @endif">
...
</div>
