最满意答案

模板加载了ContentViewCategory的上下文。 它只允许一个主要类别，并且可以通过使用以下方式获取其id：

$mainCatid = $this->category->id
 
 可以通过查询项目的catid属性来获取当前项目的直接父项ID。 还有很多其他可用的属性，包括类别名称。 
 
$catid = $this->item->catid
The template is loaded with the context of a ContentViewCategory. It allows only one main category, and its id can be obtained by using:
 
$mainCatid = $this->category->id
 
The current item's immediate parent's id can be obtained by querying the item's catid property. There are plenty of other properties available, including category name.
 
$catid = $this->item->catid
