WordPress 调用同分类或指定某分类下的随机文章

调用同分类下的随机文章：添加到与文章内容页相关的模板，如single.php

<?php$cat = get_the_category();foreach($cat as $key=>$category){$cat_id = $category->term_id;}$args = array('orderby' => 'rand','showposts' => 10,'cat' => $$cat_id );$query_posts = new WP_Query();$query_posts->query($args);while ($query_posts->have_posts()) : $query_posts->the_post();?><li><a href="<?php%20the_permalink();%20?>"><?php the_title(); ?></a></li><?php endwhile;?>123456789101112<?php$cat = get_the_category();foreach($cat as $key=>$category){$cat_id = $category->term_id;}$args = array('orderby' => 'rand','showposts' => 10,'cat' => $$cat_id );$query_posts = new WP_Query();$query_posts->query($args);while ($query_posts->have_posts()) : $query_posts->the_post();?><li><a href="<?php%20the_permalink();%20?>"><?php the_title(); ?></a></li><?php endwhile;?>

showposts后面的 10 是显示的文章数量

调用指定分类下的随机文章：

<?php query_posts('showposts=10&cat=1&orderby=rand');while(have_posts()) : the_post();?><a href="<?php%20the_permalink();%20?>" title="<?php the_title(); ?>"><?php the_title(); ?></a><?php endwhile; ?>123456<?php query_posts('showposts=10&cat=1&orderby=rand');while(have_posts()) : the_post();?><a href="<?php%20the_permalink();%20?>" title="<?php the_title(); ?>"><?php the_title(); ?></a><?php endwhile; ?>

cat后面的 1 是要调用的分类ID
