How can I define my own substitutions?

Add this code to your theme’s functions.php file:

 * Modify conversion table.
 * @param array $table Conversion table.
 * @return array
function my_ctl_table( $table ) {
   $table['Ъ'] = 'U';
   $table['ъ'] = 'u';

   return $table;
add_filter( 'ctl_table', 'my_ctl_table' );

How can I redefine non-standard locale?

For instance, if your non-standard locale is uk_UA, you can redefine it to uk by adding the following code to your theme’s function.php file:

 * Use non-standard locale.
 * @param string $locale Current locale.
 * @return string
function my_ctl_locale( $locale ) {
    if ( 'uk_UA' === $locale ) {
        return 'uk';

    return $locale;
add_filter( 'ctl_locale', 'my_ctl_locale' );

How can I define my own transliteration of titles?

Add similar code to your theme’s functions.php file:

 * Filter title before sanitizing.
 * @param string|false $result Sanitized title.
 * @param string       $title  Title.
 * @return string|false
function my_ctl_pre_sanitize_title( $result, $title ) {
    if ( 'пиво' === $title ) {
        return 'beer';

    return $result;
add_filter( 'ctl_pre_sanitize_title', 10, 2 );

How can I define my own transliteration of filenames?

Add similar code to your theme’s functions.php file:

 * Filter filename before sanitizing.
 * @param string|false $result   Sanitized filename.
 * @param string       $filename Title.
 * @return string|false
function my_ctl_pre_sanitize_filename( $result, $filename ) {
    if ( 'пиво' === $filename ) {
        return 'beer';

    return $result;
add_filter( 'ctl_pre_sanitize_filename', 10, 2 );

How can I allow the plugin to work on the frontend?

Add the following code to your plugin’s (or mu-plugin’s) main file. This code won’t work being added to a theme’s functions.php file.

 * Filter status allowed Cyr To Lat plugin to work.
 * @param bool $allowed
 * @return bool
function my_ctl_allow( bool $allowed ): bool {
    $uri = isset( $_SERVER['REQUEST_URI'] ) ?
        sanitize_url( wp_unslash( $_SERVER['REQUEST_URI'] ) ) :

    if ( 0 === strpos( $uri, '/divi-comments' ) ) {
        return true;

    return $allowed;

add_filter( 'ctl_allow', 'my_ctl_allow' );

How can I limit post types for background conversion?

Add similar code to your theme’s functions.php file:

 * Filter post types allowed for background conversion.
 * @param array $post_types Allowed post types.
 * @return array
function my_ctl_post_types( $post_types ) {
    return [
        'post'          => 'post',
        'page'          => 'page',
        'attachment'    => 'attachment',
        'product'       => 'product',
        'nav_menu_item' => 'nav_menu_item',
add_filter( 'ctl_post_types', 'my_ctl_post_types' );

How can I convert many posts/terms using wp-cli?

Use the following command in the console:

wp cyr2lat regenerate [--post_type=<post_type>] [--post_status=<post_status>]

-post_type is a list of post types,
-post_status is a list of post statuses.

How can I regenerate thumbnails safely?

Regeneration of thumbnails with the command wp media regenerate can break links in old posts as file names become transliterated.

To avoid it, deactivate cyr2lat plugin during regeneration:

wp media regenerate --skip-plugins=cyr2lat

Can I contribute?

Yes, you can!

The plugin supports Russian, Belorussian, Ukrainian, Bulgarian, Macedonian, Serbian and Kazakh characters. Unfortunately, support for other languages (Greek, Armenian, Georgian, Hebrew, and Chinese) does not work at all.

С последним обновлением стали корректно работать ранее созданные атрибуты, раньше после выгрузки отключал плагин, сейчас работает как надо. Спасибо!

Плагин отличный (6.0.5), транслитерировал урлы (слаги для продвинутых) записей, страниц и меню и всего остального.Обратите внимание, что транслитерацию урлов всех меток (/tag/) и категорий (/category/) он тоже сделает, а в настройках нет отдельных пунктов отвечающих за метки и категории.

После обновления WordPress перестал выполняться запрос к базе данных , т.е. просто ничего не выдавало. я обновила все плагины , в том числе и Cyr2Lat. проблема не решилась. На хостинге проверили БД, ошибок не было. Меня спас тестовый аналогичный сайт, на котором WP был обновлен, но все работало хорошо. и вот там после обновления вашего плагина, картина с запросом повторилась, т.е не работал запрос к БД у меня была старая версия 5.3.0. после отката на нее, запрос отрабатывает отлично.

Українська транслітерація не відповідає постанові Кабінету Міністрів України від 27 січня 2010 р. № 55, яка визначає стандарт для транслітерації української мови, треба вручну виправляти.
