本文实例总结了wordpress随机调用显示文章的方法。分享给大家供大家参考。具体方法如下：
在wordpress中要随机显示文章这里给大家介绍了三种调用随机文章的方法,有需要的朋友可根据自己的情况进行选择.
方法一:采用wordpress内置函数,在需要的时候直接调用以下代码：
复制代码
代码如下:<ul>
<?php $rand_posts = get_posts('numberposts=5&orderby=rand');
foreach( $rand_posts as $post ) : ?>
<li>
<a href="<?php the_permalink (); ?>"><?php the_title(); ?></a>
</li>
<?php endforeach; ?>
</ul>
<?php $rand_posts = get_posts('numberposts=5&orderby=rand');
foreach( $rand_posts as $post ) : ?>
<li>
<a href="<?php the_perma
</li>
<?php endforeach; ?>
</ul>
方法二:用query_posts生成随机文章列表,代码如下:
复制代码
代码如下:<?php
query_posts('showposts=10&orderby=rand');
if ( have_posts() ) : while ( have_posts() ) : the_post();
?>
<li><em><?php echo $j++;?></em><a href="<?php the_permalink (); ?>"><?php the_title(); ?></a></li>
<?php
endwhile; else:
?>
query_posts('showposts=10&orderby=rand');
if ( have_posts() ) : while ( have_posts() ) : the_post();
?>
<li><em><?php echo $j++;?></em><a href="<?php the_perma
<?php
endwhile; else:
?>
没有可显示的文章,代码如下:
复制代码
代码如下:<?php
endif;
wp_reset_query();
?>
endif;
wp_reset_query();
?>
方法三:在函数模版function.php中添加函数,然后调用,在function.php文件中添加以下代码:
复制代码
代码如下:function random_posts($posts_num=8,$before='<li>',$after='</li>'){
global $wpdb;
$sql = "SELECT ID, post_title,guid
FROM $wpdb->posts
WHERE post_status = 'publish' ";
$sql .= "AND post_title != '' ";
$sql .= "AND post_password ='' ";
$sql .= "AND post_type = 'post' ";
$sql .= "ORDER BY RAND() LIMIT 0 , $posts_num ";
$randposts = $wpdb->get_results($sql);
$output = '';
foreach ($randposts as $randpost) {
$post_title = stripslashes($randpost->post_title);
$permalink = get_permalink ($randpost->ID);
$output .= $before.'<a href="'
. $permalink . '" rel="bookmark" title="';
$output .= $post_title . '">' . $post_title . '</a>';
$output .= $after;
}
echo $output;
}//random_posts()参数有$posts_num即文章数量,$before开始标签默认<li>,$after=结束标签默认</li>
global $wpdb;
$sql = "SELECT ID, post_title,guid
FROM $wpdb->posts
WHERE post_status = 'publish' ";
$sql .= "AND post_title != '' ";
$sql .= "AND post_password ='' ";
$sql .= "AND post_type = 'post' ";
$sql .= "ORDER BY RAND() LIMIT 0 , $posts_num ";
$randposts = $wpdb->get_results($sql);
$output = '';
foreach ($randposts as $randpost) {
$post_title = stripslashes($randpost->post_title);
$perma
$output .= $before.'<a href="'
. $perma
$output .= $post_title . '">' . $post_title . '</a>';
$output .= $after;
}
echo $output;
}//random_posts()参数有$posts_num即文章数量,$before开始标签默认<li>,$after=结束标签默认</li>
然后在需要调用随机文章的地方插入下面的代码:
复制代码
代码如下:<div class="right">
<h3>随便找点看看！</h3>
<ul>
<?php random_posts(); ?>
</ul>
</div>
<h3>随便找点看看！</h3>
<ul>
<?php random_posts(); ?>
</ul>
</div>
