[DICA] Tornar exibição de produtos na página principal aleatória

Recommended Posts

Estou somente traduzindo a dica postada pelo usuário burpitt em Randomize Home Featured Products

Se você quer fazer com que os produtos que aparecem de forma aleatória na página principal de sua loja é só procurar o arquivo loja/modules/homefeatured/homefeatured.php e encontrar a seguinte linha:

 

$products = $category->getProducts(intval($params['cookie']->id_lang), 1, ($nb ? $nb : 10));

Então você altera a mesma para o seguinte código:

 

$products = $category->getProducts(intval($params['cookie']->id_lang), 1, ($nb ? $nb : 10), 'date_add', 'DESC', false, true, true, $nb);

Eu testei isso no Prestashop 1.5.6 e funcionou perfeitamente, na dica alguns testaram em versões anteriores e também obtiveram resultado positivo.

Lembrando que essa linha pode mudar um pouco tb. Uso a versao 1.5.6.0 e a linha que modifiquei estava assim:

 

$products = $category->getProducts((int)Context::getContext()->language->id, 1, ($nb ? $nb : 10));

 

Mas substitui como foi comentado e deu certinho.

 

Obrigado pela ajuda.

Vitor Hugo, pra voce "mexer" nas linhas de programação voce tem de acessar seu site por ftp e baixar os arquivos .tpl pra sua maquina e fazer as alterações. Sugiro que sempre faça um backup do arquivo que voce for "mexer" pq se der algo errado voce pode substituir com o original. Uso o programa ftp FilleZilla para acessar o meu servidor onde hospedo meu site. Pra "mexer" nos arquivos .tpl eu uso o notepad++. Gosto mto dele pq é bem simples e eficiente. Espero ter ajudado.

Você pode também usar o Cpanel para fazer isso, mas é sempre bom ter cuidado, monte uma loja de teste ou faça backup de seus arquivos.
