Hi,
I think that the solution will be to do it by editing the "show_default" file through the "product" view of your front-end template, and changing these lines :
<span id="hikashop_product_price_main" class="hikashop_product_price_main">
<?php
//LAYOUT listing_price
if ($this->params->get('show_price')) {
$this->row = & $this->element;
$this->setLayout('listing_price');
echo $this->loadTemplate();
}
?>
</span>
by :
<span id="hikashop_product_price_main" class="hikashop_product_price_main">
<?php
//LAYOUT listing_price
if($this->element->product_id != YOUR_PRODUCT_ID){
if ($this->params->get('show_price')) {
$this->row = & $this->element;
$this->setLayout('listing_price');
echo $this->loadTemplate();
}
}
?>
</span>
Note that you'll have to replace your
YOUR_PRODUCT_ID to your donation product id, you'll be able to find it through your product listing screen through the "
Hikashop->Product" page.
Hope this will help you a little.
