Popularity Contest是个不错的插件，可以根据点击量，评价次数，trackbacks等计算一个文章的受欢迎程度，然后列出来。为了跟用户当前浏览的页面相关性更好，我做了一些修改。
这个插件有2个function可用
akpc_most_popular_in_cat和akpc_most_popular，分别是指定一个分类id或取当前分类和所有的排名。
但是akpc_most_popular_in_cat有一点问题，就是原来的sql语句是在show_top_ranked_in_cat里面的sql是
WHERE tt.term_id = ‘”.intval($cat_ID).”‘
这样，只能在一个分类里面查找，需要修改成支持多个分类id的。改成如下
WHERE tt.term_id in (“.$cat_ID.”)
这样就支持多个分类id了，还有一个问题是取的当前的相关分类id，我们已经解决了。在sidebar.php里面加入如下代码，即可。根据不同的theme，可能需要做些调整。
<li id="hot-article" class="sb1">
<h2 class="widgettitle">热门文章</h2><ul class="pop">
<?php if ( function_exists('akpc_most_popular') ) : ?>
<?php if (is_category()) {
//echo $cat;
$categories= get_categories('child_of='.$cat);
$categoryIDS = array($cat);
foreach ($categories as $category) {
array_push($categoryIDS, $category->term_id);
}
$categoryIDS = implode(",", $categoryIDS);
akpc_most_popular_in_cat(10, "<li>", "</li>", $categoryIDS) ;
}else if ( is_single()){
$categories = get_the_category();
$categoryIDS = array();
foreach ($categories as $category) {
array_push($categoryIDS, $category->term_id);
}
$categoryIDS = implode(",", $categoryIDS);
akpc_most_popular_in_cat(10, "<li>", "</li>", $categoryIDS) ;
}else{
?>
<?php akpc_most_popular($limit=10); ?>
<?php }
endif; ?></ul>
</li>
<h2 class="widgettitle">热门文章</h2><ul class="pop">
