求个一个smarty写的注册登录页面
需要一个smarty 写的注册登录页面的代码,另外需要项目建立需要的什么文件能截图,百度搜索的不能用,本人想通过这个学习下samrty,我这里先谢谢了。
------解决思路----------------------
自己写一个smarty自定义函数,按照规范放到插件目录下就行了呗.......比如   函数名是login  后面的几个作为参数


smarty的可扩展性非常好,所以系统函数并不多,你需要什么功能,你就可以自己定义,规范也挺简单的,
比如smarty_function_自定义函数名,然后把文件名也写成这样,然后放到plugin目录下就行了。

smarty的作用不仅仅是界面分离的一种正则替换,缓存技术才是关键,不过这个也不过是filemtime和crc32等等的校验
