完美解决WordPress文章ID不连续的方法

// WordPress连续ID，禁用草稿功能函数开始

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");
$lastID++;
$wpdb->query("ALTER TABLE $wpdb->posts AUTO_INCREMENT = $lastID");
}
// 将函数钩在新建文章、上传媒体和自定义菜单之前。
add_filter( 'load-post-new.php', 'keep_id_continuous' );
add_filter( 'load-media-new.php', 'keep_id_continuous' );
add_filter( 'load-nav-menus.php', 'keep_id_continuous' );
// 禁用自动保存，所以编辑长文章前请注意手动保存。
add_action( 'admin_print_scripts', create_function( '$a', "wp_deregister_script('autosave');" ) );
// 禁用修订版本
remove_action( 'pre_post_update' , 'wp_save_post_revision' );

// WordPress连续ID，禁用草稿功能函数结束

// 使WordPress在原生编辑器（tiny）下发表文章时，不去除空格
add_filter('tiny_mce_before_init', 'preserve_nbsp_chars');
function preserve_nbsp_chars($initArray) {
$initArray['entities'] = '160,nbsp,'.$initArray['entities'];
return $initArray;
}
