PHP Help - X-Cart Merge two products??

Hello,

I need some help, currently I am working on a eccommerce site using X-Cart. I am pretty much done except I am trying to make it so that a customer has different options when buying a product

ex.

• Digital Download Only
• Digital Download + CD
• Digital Download + USB

I tried everything I can think of to make the code work here is what I have:

 {if $product.appearance.buy_now_buttons_enabled}
    {if $product.forsale ne "B"}
      <div class="buttons-row buttons-auto-separator">
   <a href="cart.php?mode=add&amp;productid=17533&amp;amount=1&amp;redirect_to_cart=Y">
        {include file="CD.tpl" type="input" additional_button_class="main-button add-to-cart-button"}
</a>

Code (markup):

As you can see I have made so that the other "Add-on" Product is in <a> around the button. This had mixed results, sometimes it would work other times not.

Is their a way to make so that one <a href> link could combine the two products?

Ex.

<a href="cart.php?mode=add&amp;productid=17533&amp;add&amp;$productid&amp;amount=1&amp;redirect_to_cart=Y">???

Sorry I really have no knowledge of PHP at all other than trial and error.

But any help would be greatly appreciated.
Thanks,
Tyler

 

Use the product options module. It does exactly this.

X-Cart comes with that now, but if you have an older version, it's an add-on module.

If you have X-Cart 5, it's included in the paid version. Here's a link to the module you need.

I hope you find this helpful.
