wpml_import_get_trid_from_imported_translations
Enables imported translations to be connected to existing originals by retrieving the translation record ID

WPML Version: 4.9.4

This filter is useful when you import translations without their associated source post (which is already on the site). It allows 3rd-party code to retrieve a translation record ID (trid) to reconnect original content with its imported translations.

Use cases:

– Originals exist on the site (not imported), while translations are imported from an external source (spreadsheet or external tool).

– Originals were previously imported and their import meta was cleaned up; new language translations are added later.

– Any workflow where translations must be connected to originals via a shared business key (SKU, slug, external ID, etc.).

add_filter( 'wpml_import_get_trid_from_imported_translations', integer $trid, object $firstTranslation )

$trid (int|null)

The trid resolved by the importer, or null if none was found.

$firstTranslation (object)

The first translation post object, with properties: element_id, translation_group, language_code, source_language_code.

add_filter( 'wpml_import_get_trid_from_imported_translations', 
function( $trid, $firstTranslation ) {
if ( $trid ) {
return $trid;
}

$sku = get_post_meta( $firstTranslation->element_id, '_sku', true );
if ( ! $sku ) {
return $trid;
}

// Find the original post with the same SKU and return its trid.
$original_id = wc_get_product_id_by_sku( $sku );
if ( ! $original_id ) {
return $trid;
}

$details = apply_filters( 'wpml_element_language_details', null, [
'element_id' => $original_id,
'element_type' => 'post_product',
] );

return $details ? $details->trid : $trid;
}, 10, 2 );
