Laravel/Blade: How to style error message in form
提问by Alfred Bez
I made a form with validation (laravel with blade template engine) and it works as expected.
我制作了一个带有验证的表单（带有刀片模板引擎的 laravel）并且它按预期工作。
Here's the code:
这是代码：
@if ($errors->first('email'))
{{ Form::text('email', null, $attributes = array('class'=>'error')) }}
{{ $errors->first('email', '<small class=error>:message</small>') }}
@else
{{ Form::text('email') }}
@endif
Is there a cleaner solution?
有更清洁的解决方案吗？
I'd like to write Form::text('email')only once...
我只想写Form::text('email')一次...

This should be fairly self-explanatory
这应该是不言自明的
{{ Form::text('email', null, $attributes = $errors->has('email') ? array('class'=>'error') : array()) }}
@if ($errors->has('email'))
{{ $errors->first('email', '<small class=error>:message</small>') }}
@endif

You should use a macro if you really want to be elegant:
如果你真的想优雅，你应该使用宏：
Form::macro('textWithErrors', function($name, $value, $attributes, $errors){
if ($errors->has($name)) {
if (array_key_exists('class', $attributes)) {
$attributes['class'] .= ' error';
} else {
$attributes['class'] = 'error';
}
}
$output = Form::text($name, $value, $attributes);
if ($errors->has($name)) {
$output .= $errors->first($name, '<small class=error>:message</small>');
}
return $output;
});
Use Form::textWithErrors()in place of the Form::text()call, and pass in the errors MessageBag, which is always defined.
使用Form::textWithErrors()替代的Form::text()呼叫，并传递错误MessageBag，它总是被定义。

Alfred, you can also do this, think this is fairly simple
阿尔弗雷德，你也可以这样做，觉得这很简单
{ Form::text('email', null, $attributes = $errors->has('email') ? array('class'=>'error') : array()) }}
<span class="errors">{{ $errors->first('email') }}
Your css class can be something like this
你的 css 类可以是这样的
.errors { color: #F00; }
This errors is only executed when the validation rules fail
此错误仅在验证规则失败时执行
