如何使用codeigniter迭代ionize-cms中的数组？

Question

我正在使用Ionize cms作为我网站的后端,我想创建自己的标签 - 用于从我自己的表中传递数据.我已经按照本教程创建自定义标记,并通过它 - 将数据传递给视图,但我不断收到错误:

标签缺失:演示,范围:.

这是我的观点:

<ul>
    <ion:demo:details> 
        <li><ion:detail field="user_name" /></li>
    </ion:demo:details>
</ul>

以下是我添加到TagManager.php的更改

 public static $tag_definitions = array
    (
    // <ion:demo:authors /> calls the method “tag_details”
    "demo:details" =>      "tag_details",
    "demo:details:detail" =>    "tag_detail",
    );

我还尝试创建一个简单的codeigniter控制器并使用view()传递数据并执行以下操作:

<ul>
   <?php foreach($details as $detail): ?>
     <li>
     <?php echo $detail['name'] ?>
     </li>
    <?php endforeach ;?>
</ul>

但是我得到了未定义的错误$details.

改变了标签,现在它很好.

<?php
class TagManager_Data extends TagManager

{
   public static $tag_definitions = array(

      "authors" => "tag_authors",
      "authors:author" => "tag_author",
   );

    public static function index(FTL_Binding $tag)
   {
      $str = $tag->expand();
      return $str;
   }

   public static function tag_authors(FTL_Binding $tag)
   {
      $str = '';
      $authors = [["name" => 'josh', "foo" => 'josh'], ["name" => 'joshjosh', "foo" => 'josh'], ["name" => 'josh', "foo" => 'josh']];
      foreach($authors as $author) {
         $tag->set('author', $author);
         $str.= $tag->expand();
      }

      return $str;
   }

   public static function tag_author(FTL_Binding $tag)
   {
      $field = $tag->getAttribute('field');
      if (!is_null($field)) {
         $author = $tag->get('author');
         if (!empty($author[$field])) {
            return self::output_value($tag, $author[$field]);
         }

         return self::show_tag_error($tag, 'The attribute <b>"field"</b> is not set');
      }
   }
}
