El codigo que muestras parece de Prestashop 1.6, no de Prestashop 1.5, aunque quizas es posible que hayan metido una actualización importante al módulo y ahora aparezca con ese codigo tambien en la 1.5.

Gracias por la información, pero e probado todas las modificaciones y na de na, no se que tendrá la versión 1.4 pero me parece que pondré alguna versión anterior!!

De mientras si alguien descubre algo, o tiene el mismo dilema, que escriba XF..

Ah la versión, que tenia en Prestashop 1.5.3.1 era la 0.9, y aquí si que encontré la manera

En el codigo del archivo que muestras arriva tendrias que cambiar la linea:

HomeFeatured::$cache_products = $category->getProducts((int)Context::getContext()->language->id, 1, ($nb ? $nb : 8), 'position');

Por esta:

HomeFeatured::$cache_products = $category->getProducts((int)Context::getContext()->language->id, 1, ($nb ? $nb : 8), 'position', null, false, true, true, ($nb ? $nb : 8));

Eliminas todo el cache y deberia de funcionar, OJO que no lo he testeado, un saludo.

Ok, lo e probado y borrado el cache, pero no ocurre nada, no se actualiza aleatoriamente!!

Asier.S · October 3, 2014

Una cosa curiosa, eh descubierto que si guardo un producto desde Catalogo > Productos, y luego actualizo la pagina principal de la tienda, los productos si que cambian el orden, vamos que funciona, pero solo una vez!!!!!! luego por mas que actualizas la pagina no cambia!!

No lo entiendo.

Probando con otra columna de ordenado deberia funcionar, prueba con la siguiente linea:

HomeFeatured::$cache_products = $category->getProducts((int)Context::getContext()->language->id, 1, ($nb ? $nb : 8), 'date_add', null, false, true, true, ($nb ? $nb : 8));

Gracias COTOKO, pero pasa lo mismo, solo se actualiza si antes guardo un producto cualquiera!!

Despues de tantos mensajes me di a la tarea de testearlo, el resultado es que la ultima linea de codigo que te di es la correcta, solo que si tienes habilitada la opcion de cache en rendimiento entonces no funcionara, la solucion final teniendo habilitado el cache seria...

Primero como ya te lo habia indicado cambiar la linea:

HomeFeatured::$cache_products = $category->getProducts((int)Context::getContext()->language->id, 1, ($nb ? $nb : 8), 'position');

Por esta:

HomeFeatured::$cache_products = $category->getProducts((int)Context::getContext()->language->id, 1, ($nb ? $nb : 8), 'date_add', null, false, true, true, ($nb ? $nb : 8));

Y segundo, cambiar el codigo:

	public function hookDisplayHome($params)
	{
		if (!$this->isCached('homefeatured.tpl', $this->getCacheId()))
		{
			$this->_cacheProducts();
			$this->smarty->assign(
				array(
					'products' => HomeFeatured::$cache_products,
					'add_prod_display' => Configuration::get('PS_ATTRIBUTE_CATEGORY_DISPLAY'),
					'homeSize' => Image::getSize(ImageType::getFormatedName('home')),
				)
			);
		}

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

Por este:

	public function hookDisplayHome($params)
	{
		$this->_clearCache('*');
		if (!$this->isCached('homefeatured.tpl', $this->getCacheId()))
		{
			$this->_cacheProducts();
			$this->smarty->assign(
				array(
					'products' => HomeFeatured::$cache_products,
					'add_prod_display' => Configuration::get('PS_ATTRIBUTE_CATEGORY_DISPLAY'),
					'homeSize' => Image::getSize(ImageType::getFormatedName('home')),
				)
			);
		}

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

Ahora si lo he testeado con o sin cache habilidato y funciona correctamente, un saludo.

Muchas gracias COTOKO.

Esa es la solución, funciona perfecto. Espero no tener efectos secundarios, jaja.

Saludos y muchas gracias.

Tema Solucionado y cerrado.
