小编DR *_*rry的帖子

我想id在点击它时对表格进行排序.它正在工作,但主要的是引导箭头上下图标也应该附加到id标签上.

当数据以降序显示时,arrow-bottom应显示引导程序图标,当数据按升序显示时,arrow-up应显示图标.

UsersController.php

 public $paginate = array('limit'=>4);

 public function index() {
      $this->User->recursive = 0;
      $this->set('users', $this->paginate());
 }

index.ctp

<div class="users index">
<h2><?php echo __('Users'); ?></h2>

<table class="zebra-striped table-bordered " cellpadding="0" cellspacing="0">
<tr>
        <th>
            <a href='' >
                <?php echo $this->Paginator->sort('id'); ?>
                 <i class='icon-arrow-up'></i>
            </a> 
        </th>
        <th><a href='' >First Name <i class='icon-arrow-down'></i>
       </a>   </th>
        <th>Last Name <i class='icon-resize-full'></i></a></th>

</tr>
    <?php foreach ($users as $user): ?>
    <tr>
    <td><?php echo h($user['User']['id']); ?>&nbsp;</td>
    <td><?php echo h($user['User']['first_name']); ?>&nbsp;</td> …

我想创建带有自定义验证错误消息的自定义验证规则.为此,我创建了一条规则:

$rule => [
    'app_id' => 'isValidTag'
]

并为自定义消息:

$message => [
   app_id.isValidTag   => 'Not a Valid id'
];

之后我创建了服务提供商:

class CustomValidationServiceProvider extends ServiceProvider
{
    public function boot() {

    //parent::boot();

    $this->app->validator->resolver(function($transator,$data,$rules,$messages){
            return new CustomValidator($transator,$data,$rules,$messages);
        });
    }
}

我的自定义验证类是:

class CustomValidator extends Validator {
    if(empty($parameters)) {
        return true;
    }

    $conext = $parameters[0];
    $tag = Tag::where('id', $value)->where('context', $conext)->get();

    $flag = false;
    if($tag->count() > 0) {
        $flag = true;
    }       

    return $flag;
}

一切正常,但问题是我的自定义消息app_id.isValidTag是不工作,即使所有其他消息都正常工作.

请建议我在这里或Laravel 5.2中遗漏的内容,显示消息有一些变化.任何想法将不胜感激.
