1,在app/explore/main.php下添加

//99行添加模块
if (TPL::is_output('block/content_index.tpl.htm', 'explore/index'))
{
// $posts_list = $this->model('posts')->get_hot_posts(null, $category_info['id'], null, $_GET['is_recommend'], $_GET['page'], 12);
$posts_list = $this->model('posts')->get_posts_list(question, $page = 1, $per_page = 10, $sort = null, $topic_ids = null, $category_id = null, $answer_count = null, $day = 30, $is_recommend = true);
TPL::assign('recommend_posts_list', $posts_list);
}
//添加模块，为什么用get_posts_list()，可查阅POST方法，在models/xx文件

2，新建模块文件：views/default/block/content_index.tpl.htm，内容为：

<div class="main">
<div class="focus">
<h2>精选问答</h2>
<ul>
<?php foreach ($this->recommend_posts_list AS $key => $val) { ?>
<li><a href="question/<?php echo $val['question_id']; ?>"><?php echo $val['question_content']; ?></a></a></li>
<?php } ?>
</ul>
</div>
</div>
