Как добавить связанные продукты в модуль галереи Opencart?

Question

Хочу добавить связанные товары в галерею
Ставлю в контроллер галереи:

if (isset($this->request->post['product_related'])) {
            $products = $this->request->post['product_related'];
        } elseif (isset($gallery_info)) {
            $products = $this->model_extension_module_gallery->getProductRelated($this->request->get['gallery_id']);
        } else {
            $products = array();
        }

        $data['product_relateds'] = array();
        $this->load->model('catalog/product');

        foreach ($products as $product_id) {
            $product_info = $this->model_catalog_product->getProduct($product_id);

            if ($product_info) {
                $data['product_relateds'][] = array(
                    'product_id' => $product_info['product_id'],
                    'name'       => $product_info['name']
                );
            }
        }

а в модель прописываю:

$this->db->query("DELETE FROM " . DB_PREFIX . "gallery_related_product WHERE gallery_id = '" . (int)$gallery_id . "'");
        
        if (isset($data['product_related'])) {
            foreach ($data['product_related'] as $related_id) {
                $this->db->query("DELETE FROM " . DB_PREFIX . "gallery_related_product WHERE gallery_id = '" . (int)$gallery_id . "' AND product_id = '" . (int)$related_id . "'");
                $this->db->query("INSERT INTO " . DB_PREFIX . "gallery_related_product SET gallery_id = '" . (int)$gallery_id . "', product_id = '" . (int)$related_id . "'");
            }
        }

и там же

public function getProductRelated($gallery_id) {
        $uni_gallery_related_product = array();
       
        $query = $this->db->query("SELECT * FROM " . DB_PREFIX . "gallery_related_product WHERE gallery_id = '" . (int)$gallery_id . "'");
       
        foreach ($query->rows as $result) {
            $gallery_related_product[] = $result['product_id'];
        }
       
        return $gallery_related_product;
    }

Но добавления товаров в админке модуля галереи не получилось, хоте в твиге все прописал

Оказалось забыл добавить скрипт в twig галереи

</script>
  <script type="text/javascript"><!--
// Related Product
$('input[name=\'relatedproduct\']').autocomplete({
	'source': function(request, response) {
		$.ajax({
			url: 'index.php?route=catalog/product/autocomplete&user_token={{ user_token }}&filter_name=' +  encodeURIComponent(request),
			dataType: 'json',
			success: function(json) {
				response($.map(json, function(item) {
					return {
						label: item['name'],
						value: item['product_id']
					}
				}));
			}
		});
	},
	'select': function(item) {
		$('input[name=\'relatedproduct\']').val('');

		$('#product-related' + item['value']).remove();

		$('#product-related').append('<div id="product-related' + item['value'] + '"><i class="fa fa-minus-circle"></i> ' + item['label'] + '<input type="hidden" name="product_related[]" value="' + item['value'] + '" /></div>');
	}
});

$('#product-related').delegate('.fa-minus-circle', 'click', function() {
	$(this).parent().remove();
});
//--></script>
