ECshop支持针对每个新建的类目自定义Keywords、Description Meta信息，好处就不用说了，帮助SEO或者让浏览者了解这是什么页面，但如果有几百个类目的时候，人工去写这些类目又有点累人（咱不干体力劳动的 活），花了点时间，写了个自动生成Keywords、Description的PHP脚本，支持四级分类，原理是子类目包含爸爸类目、爷爷类目。。。到顶 级类目名作为关键词，然后一句描述的话，包含这些类目的名称。大家可以根据自己需要简单的修改。
用法，在你的后台类目，默认是Admin里面创建一个新的PHP文件，文件名自定义，将下面的代码复制进去就可以了，需要生成的时候，访问一下这个文件就自动生成了。
