逆向行駛同分類的隨機文章程式碼

改佈景老是找不到這段程式碼，順便在部落格上留個記錄 @@ showposts' => 5這邊的5就是顯示5篇。

<ul>
<?php
$cat = get_the_category();
foreach($cat as $key=>$category){
$catid = $category->term_id;
}
$args = array('orderby' => 'rand','showposts' => 5,'cat' => $catid );
$query_posts = new WP_Query();
$query_posts->query($args);
while ($query_posts->have_posts()) : $query_posts->the_post();
?>
<li><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></li>
<?php endwhile;?>
</ul>

<ul>

<?php

$cat = get_the_category();

foreach($cat as $key=>$category){

$catid = $category->term_id;

}

$args = array('orderby' => 'rand','showposts' => 5,'cat' => $catid );

$query_posts = new WP_Query();

$query_posts->query($args);

while ($query_posts->have_posts()) : $query_posts->the_post();

<?php endwhile;?>
