如题
article最新消息区块可以显示各文章分类的标题
但是否有办法将各分类的「描述」文字也显示出来？
试过将<$category.description}>变量放进article_block_news.html样板里
但是似乎完全没有作用
请各位先进指导
非常感谢
模板只是版式和样式的调整，具体显示什么内容要看该模块下blocks文件夹中相应的文件，这个文件控制该区块都显示什么内容，并且对其内容的现实形式进行设置。
所以，如果想显示出区块模板中未给出的数据请检查这个文件。
至于你这个问题我小hack了一下，没有进行太多测试。
1.找到article/blocks/blocks_news.php
打开此文件找到以下代码：
/**#@+
* Function to display news item: spotlight + recent news
*
* {@link spotlight}
* {@link config}
*
* @param array $options:
* 0 - display mode: 0 - compact title list; 1 sorted by categories
* 1 - limit for article count;
* 2 - title length;
* 3 - time format;
* 4 - allowed categories;

2.在最新消息的模板文件（article_block_news.html）中的相应位置上添加显示标签
