Prestashop模块：产品页面上的产品类别

Question

I have to ask how to get other products from the same category as actual product on product page. I have plan how to do it, but i can't find proper functions(everything should be done in module.php file for sure):

1. Get parent category for product
2. Get products for that category (as array)
3. Display products in .tpl.

And only thing i can do is third point of my "plan", becouse lack of skill/knowledge.

If you can tell me which functions i should use i would be gratefull.

Answer 1

Ok. It was easier than i thought. I did it in .tpl.

{foreach from=$products item=product}
{if $product.id_category_default ===$category->id_category}
<a href="{$link->getProductLink({$product.id_product})}">Link</a>
{/if}
{/foreach}
