WordPress非插件添加文章浏览次数统计功能
时间：2019-08-29 阅读：506
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：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | /* 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 $views;} |
2.在需要显示该统计次数的地方使用下面的代码调用：
1 | 阅读：<?php post_views(' ', ' 次'); ?> |
获取浏览次数最多的文章
如果要获取上面的函数统计出来的浏览次数最多的文章，可以在 functions.php文件的最后一个 ?> 前面添加下面的代码：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | /// get_most_viewed_format/// 函数作用：取得阅读最多的文章function get_most_viewed_format($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：
1 | <?php get_most_viewed_format(); ?> |
