wordpress获取置顶文章列表的方法
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>首先，你需要了解query_posts函数。该函数的作用就是对文章进行检索、挑选、排序，在其后的LOOP循环中使用经过挑选、排序的文章。例如：</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
</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;">
<span style="line-height: 25.2px; cursor: pointer;"><u>复制代码</u></span>
</div>
代码如下:</div>
<div id="phpcode14" style='margin: 0px auto 3px; padding: 0px 3px; outline: none; line-height: 25.2px; font-size: 14px; clear: both; border-right: 1px solid rgb(0, 153, 204); background: rgb(221, 237, 251); overflow: hidden; border-left: 1px solid rgb(0, 153, 204); word-break: break-all; border-bottom: 1px solid rgb(0, 153, 204); word-wrap: break-word; font-family: tahoma, arial, "Microsoft YaHei";'>
<br>
<?php<br>
query_posts('posts_per_page=10&ignore_sticky_posts=1&orderby=rand');<br>
while(have_posts()):the_post();<br>
echo '<li>';the_title();echo '</li>';<br>
endwhile;<br>
wp_reset_query();</div>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
将随机列出一条文章的标题。至于query_posts的具体参数，请参考开发手册。</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
接下来，我们就是要通过对query_posts的参数进行调整，挑选出置顶的文章列表了。</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
</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;">
<span style="line-height: 25.2px; cursor: pointer;"><u>复制代码</u></span>
</div>
代码如下:</div>
<div id="phpcode15" style='margin: 0px auto 3px; padding: 0px 3px; outline: none; line-height: 25.2px; font-size: 14px; clear: both; border-right: 1px solid rgb(0, 153, 204); background: rgb(221, 237, 251); overflow: hidden; border-left: 1px solid rgb(0, 153, 204); word-break: break-all; border-bottom: 1px solid rgb(0, 153, 204); word-wrap: break-word; font-family: tahoma, arial, "Microsoft YaHei";'>
<br>
$query_post = array(<br>
'posts_per_page' => 10,<br>
'post__in' => get_option('sticky_posts'),<br>
'caller_get_posts' => 1<br>
);<br>
query_posts($query_post);<br>
?><br>
<ul style="display:none;"><br>
<?php while(have_posts()):the_post(); ?><br>
<li><a href="<?php the_permalink(); ?>" title="<?php the_title(); ?>"><?php the_title(); ?></a></li><br>
<?php endwhile; ?><br>
</ul><br>
<?php<br>
wp_reset_query();</div>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
参数用一个数组的形式放在$query_post中，关键的参数为'post__in' =>get_option('sticky_posts')和'caller_get_posts' => 0。</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
'post__in' => get_option('sticky_posts')确定了该LOOP调用的是置顶文章列表。'caller_get_posts'的作用是排除非指定性文章，即除了置顶文章之外，不显示其他的文章。（不添加的情况下，如果置顶文章条目不足'posts_per_page'规定的值，会用最新文章替补完整。）</p>
