Discuz!X3.0将模块化发表主题功能

Discuz扩展中心

6 z# m( x  W! c2 j, ^1 w/ s模块化发表主题功能
发表主题的方法只实现最简单的普通主题的发表功能，其它主题功能如特殊主题、抢楼帖、分类信息等均以扩展方式实现
具体实现方法是：给model_forum_thread->newthread()方法的执行前后绑定相应的扩展方法，部分代码如下：

, v6 f3 _  h& v" F8 @( f. [        $modthread = C::m('forum_thread');

        $bfmethods = $afmethods = array();
4 _5 T- A5 |5 A! K1 _4 x# s- E
        //note 抢楼贴
$ k2 G( O; Q0 H/ I- v9 l        if($_GET['rushreply']) {
                $bfmethods[] = array('class' => 'extend_thread_rushreply', 'method' => 'before_newthread');
                $afmethods[] = array('class' => 'extend_thread_rushreply', 'method' => 'after_newthread');
        }

        $afmethods[] = array('class' => 'extend_thread_image', 'method' => 'after_newthread');
