I have an affiliate website. When clicking the product, I would like it to redirect to an affiliate link. No matter how I try it does not redirect to the affiliate link. You just have to show me how to do it in PHP and in .htaccess and I will do the rest of all the affiliate links I have. Also I would like the affiliate link to be cloaked. I am using PHP, smarty template engine, OOP. Another requirement is a fix on my subcategory, I would like the subcategory to be highlighted after clicking it. Thank you.
