Để hiển thị Sản phẩm ngẫu nhiên trong Prestashop có 2 giải pháp chính: viết module mới dựa trên module blocknewproducts hoặc sửa code module này.

Mở và sửa file …/modules/blocknewproducts/blocknewproducts.php

Tìm : getNewProducts

$newProducts = Product::getNewProducts(intval($params['cookie']->id_lang), 0, Configuration::get('NEW_PRODUCTS_NBR'));

thay thế

$newProducts = Product::getNewProducts(intval($params['cookie']->id_lang), 0, 100);
shuffle($newProducts);
array_splice($newProducts, Configuration::get('NEW_PRODUCTS_NBR') );

 

Cách 2: Sửa file classes\Product.php

Tìm Getnewproducts

 /**
 * Get new products
 *
 * @param integer $id_lang Language id
 * @param integer $pageNumber Start from (optional)
 * @param integer $nbProducts Number of products to return (optional)
 * @return array New products
 */
