将变量传递到Smarty视图文件

你好，我正试图将一个值从php文件发送到tpl文件。

当我在php文件中打印r时，我看到我的值是在数组中定义的，但当我打印tpl文件时，我看不到这个元素。

 <img src="{$product.manufacturer_name}" alt="" title="" itemprop="image" />

和我的控制器

    $special = Product::getProducts((int)$this->langID , 0,6, 'name', 'DESC', 51);

                foreach ($special as $specia) 
                {
                    $id_image = Product::getCover($specia['id_product']);
    // get Image by id
                if (sizeof($id_image) > 0) 
                        {
                    $image = new Image($id_image['id_image']);
        // get image full URL
                        $image_url = _PS_BASE_URL_._THEME_PROD_DIR_.$image->getExistingImgPath()."-home_default.jpg";
                        $specia['manufacturer_name']=$image_url;   
                        }
                }
                $dir = _PS_MODULE_DIR_.'/ptspagebuilder/views/templates/front/widgets/sub/products.tpl';
$tdir = _PS_ALL_THEMES_DIR_ . _THEME_NAME_ . '/modules/ptspagebuilder/views/templates/front/widgets/sub/products.tpl';
                if (file_exists($tdir)) {
                    $dir = $tdir;
                }
    // get Product cover image (all images is possible retrieve by
    // Image::getImages($id_lang, $id_product) or
    // $productInstance->getImages($id_lang))


                $setting['product_tpl'] = $dir;
                $setting['products'] = $special;
                $output = array('type' => 'flashsale','data' => $setting);
                return $output;
            }
