最近在研究discuz! 但就是搞不懂他怎么在输入127.0.0.1/forum.php后直接加载discuz.htm这个模板呢,百思不得其解.记住本帖一定要说道理,不能干巴巴的,否则是不给分的,这回给分可是不少啊. 一百分

回复讨论(解决方案)

上面这段代码里面在逻辑上就没有discuz这个变量存在,所以俺就是纳闷,他为啥能加载呢

$mod = !in_array(C::app()->var['mod'], $modarray) ? 'index' : C::app()->var['mod'];
没有mod参数就是mod=index;
你到/source/module/forum下就能找到forum_index.php
这就是首页的后台文件
在最后include template('diy:forum/discuz:'.$gid);
就是引入了discuz.html

道理，不能干巴巴的

嗯,你说的真明白,你肯定能获得分了,不过我还有个问题,能解答下吗?$mod = !in_array(C::app()->var['mod'], $modarray) ? 'index' : C::app()->var['mod'];句中的"C::app()->var['mod']"我不理解,这里的双冒号是类中的静态方法吧?还是个啥?如是静态方法,那app()是怎么来的?我搜了一下var这个数组没有呢,是不是我理解错了.肯定给你分的.骗你小狗.

C类：source/class/class_core.php，在文件最下面，继承了core类，就在本文件的上面，在core类的上面调用了C::creatapp();此静态方法用到了discuz_application::instance();
discuz_application类：source/class/discuz/discuz_application.php，这个类是核心类，所有入口文件调用的其实就是它，里面定义了$var数组，并有一句$this->var = & $_G;，我想$_G不会不认识吧，所以$_G['mod']也能获取mod的参数值
