相信很多朋友都在使用Wordpress插件WP-Postviews或者类似插件，对于大多数朋友来说，使用这样的插件仅仅需要它的点击量统计功能，其他的一切都是多余的，所以倡萌决定弃用插件，打算使用代码来实现统计功能。前不久在Tstyle Pro 1.2版中提取了DAFI使用的统计代码，但是发觉不能正常使用，真的很郁闷，也不知到底哪里出错了，今天终于找到了真正好用的代码，一起来分享一下。

该Wordpress非插件版post_view是DH参考willin kan大师的my_visitor插件来写的，刷新一次文章页面就统计一次。倡萌觉得很简洁很好用。

WordPress非插件版post_view

操作很简单，将下面的文章点击量统计代码添加到你主题的functions.php的最后一个 ? > 的前面

/* 访问计数 */
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($post_ID, 'views', 1, true);
}
}
}
}
add_action('wp_head', 'record_visitors');
/// 函数名称：post_views
/// 函数作用：取得文章的阅读次数
function post_views($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;
}

然后在需要显示点击数的地方添加下面的调用代码即可
阅读：

<?php post_views(' ', ' 次'); ?>

DH还附带提供了下面两个参数，供大家参考
(1)get_most_viewed_format 得到最多阅读的文章，列出5个。

/// get_most_viewed_format
/// 函数作用：取得阅读最多的文章
function get_most_viewed_format($mode = '', $limit = 10, $show_date = 0, $term_id = 0, $beforetitle= '(', $aftertitle = ')', $beforedate= '(', $afterdate = ')', $beforecount= '(', $aftercount = ')') {
global $wpdb, $post;
$output = '';
$mode = ($mode == '') ? 'post' : $mode;
$type_sql = ($mode != 'both') ? "AND post_type='$mode'" : '';
$term_sql = (is_array($term_id)) ? "AND $wpdb->term_taxonomy.term_id IN (" . join(',', $term_id) . ')' : ($term_id != 0 ? "AND $wpdb->term_taxonomy.term_id = $term_id" : '');
$term_sql.= $term_id ? " AND $wpdb->term_taxonomy.taxonomy != 'link_category'" : '';
$inr_join = $term_id ? "INNER JOIN $wpdb->term_relationships ON ($wpdb->posts.ID = $wpdb->term_relationships.object_id) INNER JOIN $wpdb->term_taxonomy ON ($wpdb->term_relationships.term_taxonomy_id = $wpdb->term_taxonomy.term_taxonomy_id)" : '';
// database query
$most_viewed = $wpdb->get_results("SELECT ID, post_date, post_title, (meta_value+0) AS views FROM $wpdb->posts LEFT JOIN $wpdb->postmeta ON ($wpdb->posts.ID = $wpdb->postmeta.post_id) $inr_join WHERE post_status = 'publish' AND post_password = '' $term_sql $type_sql AND meta_key = 'views' GROUP BY ID ORDER BY views DESC LIMIT $limit");
if ($most_viewed) {
foreach ($most_viewed as $viewed) {
$post_ID = $viewed->ID;
$post_views = number_format($viewed->views);
$post_title = esc_attr($viewed->post_title);
$get_permalink = esc_attr(get_permalink($post_ID));
$output .= "<li>$beforetitle<a href="$get_permalink" title="$post_title">$post_title</a>$aftertitle";
if ($show_date) {
$posted = date(get_option('date_format'), strtotime($viewed->post_date));
$output .= "$beforedate $posted $afterdate";
}
$output .= "$beforecount $post_views $aftercount</li>";
}
} else {
$output = "<li>N/A</li>\n";
}
echo $output;
}

(2)get_totalviews 得到阅读的总数

function get_totalviews($echo = 1) {
global $wpdb;
$total_views = $wpdb->get_var("SELECT SUM(meta_value+0) FROM $wpdb->postmeta WHERE meta_key = 'views'");
if ($echo) echo $total_views;
else return $total_views;
}
