wordpress调用随机文章的一些例子

$tags = wp_get_post_tags($post->ID);
if ($tags) {
$first_tag = $tags[0]->term_id;
$args=array(‘
tag__in’ => array($first_tag),
‘post__not_in’ => array($post->ID),
‘showposts’=>10,
‘caller_get_posts’=>1
);
$my_query = new WP_Query($args);
if( $my_query->have_posts() ) {
while ($my_query->have_posts()) : $my_query->the_post(); ?>

       $cat = get_the_category();
   foreach($cat as $key=>$category){
   $catid = $category->term_id;
   }
   $args = array('orderby' => 'rand','showposts' => 8,'cat' => $catid );
   $query_posts = new WP_Query();
   $query_posts->query($args);
    while ($query_posts->have_posts()) : $query_posts->the_post();
    ?>
