我們想要實現最多人看的功能就必須對WordPress的代碼風格及編寫規范有一定了解，因此僅適合具備一定編程基礎的人進行二次開發或者直接使用現成的代碼，接下來為大家分享一個WordPress根據文章瀏覽量進行排序教程。

將下方代碼添加進functions.php外加一個php文件即可實現：

//根據瀏覽量從多到少進行排序

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;

}

//在需要調用的地方插入下方代碼

<?php get_most_viewed_format(); ?>
