Hi,
First, study this tutorial for the procedure:
www.hikashop.com/support/support/documen...-display.html#layout
1. You'll have to edit the view "product / show_default" for your frontend template.
2. In this view, 2ove this block:
<?php if ($this->config->get('show_code')) { ?>
<span id="hikashop_product_code_main" class="hikashop_product_code_main">
<?php
echo $this->element->product_code;
?>
</span>
<?php } ?>
to just
before this line
<div id="hikashop_product_quantity_main" class="hikashop_product_quantity_main">
3. Replace "span" with "div".
4. Replace the line
echo $this->element->product_code;
with
echo JText::_('ITEM_NUMBER_CUSTOM').': '.$this->element->product_code;
Then study this tutorial to "translate" the new namekey:
hikashop.com/download/languages.html#modify
(the last section = "How to modify...")
5. As a new language override, add this line:
ITEM_NUMBER_CUSTOM="Item Number"
Test in frontend, should work fine.
Of course, products need to have product codes entered, and the display of the product code must be enabled in the configuration.
