@error 指令未在 laravel 视图中显示错误

Question

我正在开发自定义 Laravel 登录实现。我从控制器返回错误如下：

$credentials = $request->only('email', 'password');
if (Auth::attempt($credentials)) {
  // Authentication passed...
  return redirect()->intended('surveys');
}else {
  return redirect()->back()->withErrors(['email', 'The Message']);
}

这是我提取此错误的视图实现：

<div class="col-md-6">
   <input id="email" type="email" class="form-control @error('email') is-invalid @enderror" name="email" value="{{ old('email') }}" required autocomplete="email" autofocus>
@error('email')
  <span class="invalid-feedback" role="alert">
      <strong>{{ $message }}</strong>
  </span>
@enderror
</div>

我只想用这种方式。由于代码最小化，不是显示错误的其他方法。 我正在使用 Laravel 7.0+

Answer 1

试试这个：

<div class="col-md-6">
     <input id="email" type="email" class="form-control @if($errors->has('email'))  is-invalid @endif " name="email" value="{{ old('email') }}" required autocomplete="email" autofocus>
  @if($errors->has('email'))
      <div class="error"></div>
      <span class="invalid-feedback" role="alert">
           <strong>{{ $errors->first('email') }}</strong>
       </span>
  @endif
</div>

Answer 2

请再试一次：

$credentials = $request->only('email', 'password');
if (Auth::attempt($credentials)) {
  // Authentication passed...
  return redirect()->intended('surveys');
}else {
  return redirect()->back()->withErrors(['email' => 'The Message']);
}
