WordPress文章浏览次数统计功能是必不可少的,不少主题已经集成该功能,如果你的主题没有集成,你可以使用 WP-Postviews 插件,或者试试本文的代码。
WordPress非插件实现文章浏览次数统计的方法,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,比较简单实用。
非插件统计文章浏览次数
1.在主题的 functions.php文件的最后一个 ?> 前面添加下面的代码:
-
/* 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 $views;
-
}
2.在需要显示该统计次数的地方使用下面的代码调用:
-
阅读:<?php post_views(‘ ‘, ‘ 次’); ?>
获取浏览次数最多的文章
如果要获取上面的函数统计出来的浏览次数最多的文章,可以在 functions.php文件的最后一个 ?> 前面添加下面的代码:
-
/// get_most_viewed_format
-
/// 函数作用:取得阅读最多的文章
-
function get_most_viewed_format($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$post_title$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;
-
}
然后使用下面的函数调用:
-
<?php get_most_viewed_format(); ?>
