worepress重新排列不连续的文章ID 筋斗云网络

可在当前主题的functions.php中加入以下PHP代码，这样如果你只是单纯发文章，不发页面，不添加菜单，不上传媒体的话，基本上此后的文章ID是连续的，而且不改变之前已经发布的文章ID，不影响SEO

function keep_id_continuous(){

global $wpdb;

$lastID = $wpdb->get_var("SELECT ID FROM $wpdb->posts WHERE post_status = 'publish' OR post_status = 'draft' OR post_status = 'private' OR ( post_status = 'inherit' AND post_type = 'attachment' ) ORDER BY ID DESC LIMIT 1");

$wpdb->query("DELETE FROM $wpdb->posts WHERE ( post_status = 'auto-draft' OR ( post_status = 'inherit' AND post_type = 'revision' ) ) AND ID > $lastID");

$wpdb->query("ALTER TABLE $wpdb->posts AUTO_INCREMENT = 1");

}

// 将函数钩在新建文章、上传媒体和自定义菜单之前。

add_filter( 'load-post-new.php', 'keep_id_continuous' );

add_filter( 'load-media-new.php', 'keep_id_continuous' );

add_filter( 'load-nav-menus.php', 'keep_id_continuous' );

// 禁用自动保存，所以编辑长文章前请注意手动保存。
