Hi,
It requires to create a template override for the button "add to cart" like explain in this documentation:
www.hikashop.com/en/support/documentatio...tation.html#override
For the buttons:
You need to create the file templates/YOUR_TEMPLATE/html/hikashop_button.php. We invite you to look at the file administrator/components/com_hikashop/helpers/cart.php for the default code of the function you will define in it. In that file, you will be able to define the function:
hikashop_button_render($map,$name,$ajax,$options,$url) => The $map variable contains the name of the button, the $name variable contains the value of the button (what the user see). The $ajax variable can contains additional attributes for the HTML element of your button as well as the $options attribute. The $url variable can contain a URL where to redirect when the button is used as a link. You need to return the whole HTML of your buttons at the end of your function.
Regards,
