Hello,
I'm afraid that Nicolas gave you the solution twice.
But here again the code to have the dynamic URL :
<?php echo hikashop_completeLink('product&task=contact&cid=' . (int)$this->element->product_id . $this->url_itemid); ?>
And you can use the extra parameters to force the "popup" and have JS compatible content:
[code]
<?php echo hikashop_completeLink('product&task=contact&cid=' . (int)$this->element->product_id . $this->url_itemid, true, true); ?>
If you still don't get it ; please contact someone who will have some PHP and Joomla knowledge.
Thank you for your understanding.
Jerome
