$id=$_GET['id'];

        $sql="select path from type WHERE path like '%$id%'";

        $rs=mysql_query($sql);

        $arr=mysql_fetch_assoc($rs);

       if($arr){

          $path=" and path like '%$id%'";

//我写的代码为什么不能删除有子级分类的商品呢?只能把子分类删完才能执行父类

//是where and的前后顺序问题吗?

 

比如删除女装是,需要先把休闲裤删了才行,但我想直接删完,应该怎么做呢??</code>
