WordPress教程：添加文章阅读量的最简单办法

将下面代码添加到Functions.php：

//取得文章的阅读次数 
function post_views($before = ‘点击 ‘, $after = ‘ 次’, $echo = 1) 
{ 
global $post; 
$post_ID = $post->ID; 
$views = (int)get_post_meta($post_ID, ‘views’, true); 
if ($echo) echo $before, number_format($views), $after; 
else return $views; 
} 
function record_visitors() 
{ 
if (is_singular()) { 
global $post; 
$post_ID = $post->ID; 
if($post_ID) { 
$post_views = (int)get_post_meta($post_ID, ‘views’, true); 
if(!update_post_meta($post_ID, ‘views’, ($post_views+1))) { 
add_post_meta($post_ID, ‘views’, 1, true); 
} 
} 
} 
} 
add_action(‘wp_head’, ‘record_visitors’);

在想调用的地方，直接在while ( have_posts() )的 {内使用下面代码即可：

<?php post_views(); ?>
