自己发明的一种表单自动判断POST地址的方法 ++ 节省文件数

时间：2009-09-15

来源：互联网

我们在做后台管理某个页面的时候，比如文章编辑页，经常遇到该页面的表单既用来添加、也用来修改，而大多数人的做法是，创建两个页面，或者两个模板，添加文章用addarticle.php，修改文章用editarticle.php，删除文章用delete.php，并且post的地址分别设置为action="addarticle.php" 和"editarticle.php"。。这样子的弊端就是后台文件会变多，一旦有多几个这样的页面，维护修改起来势必也要多花时间
其实我们可以这样写。。总共只有1个页面

这个也叫自己发明！
那只能够说明你都没有看过开源程序！

lz，要多学习。“发明”这个词要谨慎使用。

值得鼓励啊，新人发个东西不容易，有点想法分享给大家更不容易(即使这方法对于某些老鸟已经过时了)。
支持楼主！
