自定义wordpress仪表盘

原网址:http://www.cnblogs.com/huangcong/p/3546636.html

WordPress作为一博客管理系统，相对来说已经相当简洁了，对用户也十分友好，新手也极易上手。

仪表盘是我们登陆WordPress后看到的后台界面，映入眼帘的是各种各样的信息，如WordPress China博客消息，及其他关于WordPress的RSS信息，这些无用的东西空空的耗费着我们内存。通过定制WordPress的管理后台，我们可以让WordPress更加简单实用，易于管理。简化后台界面，去除冗余信息和代码。

WordPress内置的hooks（包括filter和action）为我们定制WordPress后台提供了完美的解决方案。通过“勾入”而非修改WordPress的核心程序，可以在不影响安装文件完整性的情况下安全地作改动。

下面介绍的代码将全部在主题模板函数functions.php文件里修改。
