Php Prestashop SQL查询，仅显示活动语言的类别名称

我在几年前开发了一个Prestashop模块。该模块根据所选类别显示新产品。我最近发现，如果我为商店设置了多种语言（例如en、fr），并且我用英语和法语编辑了类别名称。该模块将在前端显示两个名称，而不是仅显示一个基于活动车间语言的名称

我认为编辑的blocknewproduct.php中的以下代码将获取类别列表：

    public function hookdisplayHome($params)
{
    $list_id_category= Tools::jsonDecode(Configuration::get('PS_NB_NEW_PRODUCT_CATEGORY'));
    $resuilt_category=array(); 
    if($list_id_category)
    {
        $sql="select distinct id_category,name from "._DB_PREFIX_."category_lang where id_category in (".implode(',',$list_id_category).")";
        $categories=Db::getInstance(_PS_USE_SQL_SLAVE_)->executeS($sql);
    }
    if (!$this->isCached('blocknewproducts_home.tpl', $this->getCacheId('blocknewproducts-home')))
        BlockNewProducts1::$cache_new_products = $this->getNewProducts();
    {
        $this->smarty->assign(array(
            'new_products' => BlockNewProducts1::$cache_new_products,
            'categories' =>$categories,
            'mediumSize' => Image::getSize(ImageType::getFormatedName('medium')),
            'homeSize' => Image::getSize(ImageType::getFormatedName('home'))
        ));
    }

    if (BlockNewProducts1::$cache_new_products === false)
        return false;
    $this->pagination(count($this->getAllNewProducts($this->context->language->id))); // by ats_edited

    return $this->display(__FILE__, 'blocknewproducts_home.tpl', $this->getCacheId('blocknewproducts-home'));
}

任何人都可以建议需要编辑此代码的哪一行，以便只显示活动语言的类别名称

在blocknewproducts_home.tpl文件中，以下代码用于显示列表

<ul class="list-category-new-product plists">
                    <li class="plist {if !isset($id_category_select) || !$id_category_select}active{/if}"><a href="#" data-id="0" title="{l s='All' mod='blocknewproducts1'}">{l s='All' mod='blocknewproducts1'}</a></li>
                    {foreach from=$categories item='category'}
                        <li class="plist {if $category.id_category==$id_category_select}active{/if}"><a href="#" data-id="{$category.id_category}" title="{$category.name}">{$category.name}</a></li>
                    {/foreach}
                </ul>

{foreach from=$categories item='category'}

{/foreach}

很抱歉，我不是程序员，只是网页设计师，因此我需要明确的帮助。

将$sql更改为：

$sql="select distinct id_category,name from "._DB_PREFIX_."category_lang where id_category in (".implode(',',$list_id_category).") and id_lang = ".(int) $this->context->language->id;

将$sql更改为：

$sql="select distinct id_category,name from "._DB_PREFIX_."category_lang where id_category in (".implode(',',$list_id_category).") and id_lang = ".(int) $this->context->language->id;
