 <div>
    <input type="text" name="email" class="form-control" placeholder="Email"/>
    @if($errors->has('email')) <p>{{ $errors->first('email') }}</p> @endif
 </div>

Answer 1

您无需检查错误，只需执行以下操作

{!! $errors->first('email', '<dev class="error-block">:message</div>') !!}

请注意“error-block”是一个自定义css类，您可以根据自己的选择自定义html模板。

Answer 2

我有不同的方法。

在输入字段下方，我包含了额外的视图：

@include('input-errors', ['inputName' => 'inputName']) #For your case it would be 'email'

input-errors.blade.php

@foreach ($errors->get($inputName) as $message)
    <span class="input-error">{{ $message }}</span>
@endforeach

样式.css

.input-error {
    color: #ff5555;
}
