Try to add the following PHP code snippet to the child theme functions.php file
function woodmart_remove_unnecessary_vg_data( $post_id ) {
if ( ! woodmart_woocommerce_installed() ) {
return;
}
$product = wc_get_product( $post_id );
if ( ! $product ) {
return;
}
$available_variations = array();
foreach ( $product->get_children() as $child_id ) {
$available_variations[] = $product->get_available_variation( wc_get_product( $child_id ) );
}
$available_variations = array_values( array_filter( $available_variations ) );
$variations = $product->get_type() == 'variable' ? $available_variations : '';
$variations_ids = array();
$variation_gallery_data = get_post_meta( $post_id, 'woodmart_variation_gallery_data', true );
if ( ! $variations || ! $variation_gallery_data ) {
return;
}
foreach ( $variations as $variation ) {
$variations_ids[] = $variation['variation_id'];
}
foreach ( $variation_gallery_data as $key => $data ) {
if ( ! in_array( $key, $variations_ids ) && isset( $variation_gallery_data[ $key ] ) ) {
unset( $variation_gallery_data[ $key ] );
}
}
update_post_meta( $post_id, 'woodmart_variation_gallery_data', $variation_gallery_data );
}
add_action( 'save_post', 'woodmart_remove_unnecessary_vg_data' );
