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):
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.
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}
To work with all languages:
Change getProductLink({$product.id_product})}">Link
With
getProductLink({$product.id_product})}">{l s='Link' }
