WordPress非插件添加文章浏览次数统计功能

2016年5月9日     Jackie     606     百度已收录    

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:

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 .= "

  • $beforetitle$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
  • ";
    }
    } else {
    $output = "

  • N/A
  • n";
    }
    echo $output;
    }

    然后使用下面的函数调用:
