WordPress分类与标签等存档页实现置顶的方法
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>本文实例讲述了WordPress分类与标签等存档页实现置顶的方法。分享给大家供大家参考。具体分析如下：</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
在wordpress中默认能置顶文章就是只有首页了,如果我们希望分类/标签等存档页也能置顶文章我们需要二次开发.</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
现在参考wp-includes/query.php中首页置顶的代码,稍微修改一下,可以让分类页、标签页、作者页和日期页等存档页面也能像首页一样在顶部显示其范围内的置顶文章,把下面的代码放到当前主题下的functions.php中就可以了.<br>
</p>
<div style='margin: 3px auto 0px; padding: 0px 3px; outline: none; line-height: 21.6px; clear: both; border-width: 1px; border-style: solid; border-color: rgb(0, 153, 204); background: rgb(246, 251, 255); overflow: hidden; font-family: tahoma, arial, "Microsoft YaHei";'>
<div style="margin: 0px; padding: 0px; outline: none; float: right; line-height: 25.2px; font-size: 14px;">

代码如下:</div>
