我写的CCK 阴历字段模块代码

g089h515r806 的头像
Submitted by g089h515r806 on 星期三, 2009-05-06 14:48

有点长阿,费了1天多的功夫了,里面需要很多技巧,阳历转阴历的函数我是从网上找的,改造 了一下.

基本上用到创建一个CCK字段块所涉及到的各个钩子了.

看到这么多行代码,应该知道还是花费老葛不少精力的.

希望这些代码能够带动更多的人学习CCK字段模块的创建,这里面需要很多Drupal 技能的,希望这些代码,能够帮助那些有这方面的需求,但是不知道如何实现的  朋友,降低成本.也希望能够起到抛砖引玉的效果.

本课程的教学视频,明天就会整理好上传上来.

网上我也找了一圈,看代码结构都不怎么清楚,还是你这个清楚一点
不过,如果能加上节气与一般的农历节日就更好了

这个函数确实是拷贝别人的,只是把中文的双引号改造成了英文的双引号,其它没有动.网上也有其它的代码,这段代码只是一个函数,引用比较方便.而且他没有注明作者,商用什么的.

网上有段其它的代码,商用要联系原作者.所以就没有用.代码我只做了简单的测试,就是输入了几个日期,返回的结果都是对的.
