ASP进阶之文章在线管理更新(10)

80酷酷网    80kuku.com

  前面讲述了关于文章管理系统的密码及密码验证,通过密码验证可以限制一般浏览者所能进入的页面,这里所要限制的就是普通用户所不能进入的页面,也就是包括管理页面、删除文章页面、修改文章页面以及修改用户信息和修改栏目信息的页面。其实这里的主管理页面就是和文章管理系统的主页面类似的页面,只是在里面添加了一些有关管理内容的连接,以方便管理者对文章进行在线的修改删除等操作。

   下面就为大家介绍这一页面的主要程序内容,由于它和文章管理的主页面差不多,所以这里只是把其程序写出来,并注明和主页面不同的地方,其他相同的部分请大家参考本专题的第七节!
