How to translate email sending by plugin WP Mail SMTP
On this example we use a filter to translate our email message based on this doc : https://wpmailsmtp.com/docs/setting-a-custom-reply-to-email/
function wp_mail_smtp_weglot( $args ) {
$original_lang = weglot_get_original_language();
$current_language = weglot_get_current_language();
if ( $original_lang == $current_language ) {
return $args;
}
if ( ! empty( $args['message'] ) ) {
$translate_service = weglot_get_service( 'Pdf_Translate_Service_Weglot' );
$translate_message = $translate_service->translate_pdf( $args['message'], $current_language );
$args['message'] = $translate_message['content'];
}
return $args;
}
add_filter( 'wp_mail', 'wp_mail_smtp_weglot', PHP_INT_MAX );
