如何查询一篇文章属于多个栏目分类
怎么查询一篇文章属于多个栏目分类
插入的时候没有问题，取出来的时候有问题！
怎么写个函数判断这篇文章属于哪些分类，输出的时候input的属性设置checked=checked。
------解决方案--------------------
这不需要写函数，你在插入的时候应该有文章属于哪些分类的字段吧，里面存有分类ID，取出的时候循环遍历判断就好了，存在就加checked="checked"，分类不是很大的话，可以放数组里

分类是如何输出的？ 遍历出来的吧，因此遍历时，判断每项的id是否在文章的分类id中即可。
------解决方案--------------------
顶楼上，分类最好是写文件里，这样读取比较方便，遍历的时候判断即可
