WordPress文章根据浏览量从多到少进行排序的教程

WordPress程序适合新手使用，但是想要二次开发一些功能还是需要有一定变成基础的，WordPress如何根据浏览量进行排序呢？今天就分享一下文章根据浏览量从多到少进行排序的WordPress教程。

将下方代码添加进functions.php外加一个php文件即可实现：

//根据浏览量从多到少进行排序

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));
$output .= ‘<li><a href=”‘.get_permalink($post_ID).’”>’.$post_title.”;
if ($show_date) {
$posted = date(get_option(‘date_format’), strtotime($viewed->post_date));
$output .= “$beforedate $posted $afterdate”;
}
$output .= “$beforecount $post_views $aftercount</a></li>”;
}
} else {
$output = “<li>N/A</li>n”;
}
echo $output;
}
//在需要调用的地方插入下方代码
<?php get_most_viewed_format(); ?>
