下面这段代码中 if(isset($_GET['n_page'])){ //判断当前页码
的 n_page是从哪来的，我查了一下不是数据表中的字段，它到底是怎么来的，难道是随便定义的一个玩意吗

回复讨论(解决方案)
看看session里的值， 还有是哪个页面传进来的，看一下
这个应该是分页页码参数，类似这样的
http://index.php?n_page=2,3,4......
当n_page为第一页的时候，通常是获取不到参数的，所以需要判断一下$_GET['n_page']是否存在，不存在则为第一页。如果存在，则根据获取到的值，显示对应页的内容。
你不是有这样的语句吗？
"> 首页
$_GET['n_page'] 就是这样来的
通过页面链接传的值呀？
$_GET取值；没取到的清楚下，默认为第一页
你后面的分页里面都有呀
其实是由"> 首页 来的
这涉及到url传值的知识，当一个链接传到地址栏的时候$_GET[ ]数组就会截取它，因为$_GET[ ]数组是全局变量数组，专门负责截获地址栏中的值的。
只可惜大家都没有答对，上面是我悟出来的。
