Please advise on adding ClickID to "Add to cart" button in product.tpl Prestashop 1.6

[brinnington]

Hello everybody,

I would appreciate your advice.

I am trying to add a tracking ClickID to the "Add to cart" button in product.tpl.

This is so that I can better understand visitor interaction with our Prestashop site and thereby improve sales.

This is my attempt at adding the ClickID in product.tpl:

<button type="submit" name="Submit" class="exclusive">

<!-- <span>{if $content_only && (isset($product->customization_required) && $product->customization_required)}{l s='Customize'}{else}{l s='Add to cart'}{/if}</span>   -->


<span>{if $content_only && (isset($product->customization_required) && $product->customization_required)}{l s='Customize'}{else}{l s='Add to cart'}{/if}&sub1={mc_click_id}</span>

</button>

The result of adding that ClickID was the disappearance of the product page. So clearly my knowledge is lacking.

The version of Prestashop is 1.6.

Thank you in advance.

Best,

Bob
