Hi,
1. Edit the file "contact" of the view "product" via the menu Display>Views and add the code:
$doc = JFactory::getDocument();
$doc->setMetaData( 'robots', 'noindex' );
before the code:
if(!empty($this->product->images)) {
and that should do it. We'll add that for the next version of HikaShop. Thanks for the feedback.
2. There is no easy way to do that. You would have to edit the code display button to add dynamic javascript to modify the URL of the button on the fly, you would have to edit the code of the contact form to get the extra parameter from the contact page URL, and you would also need to add custom code to load the data of the options, and display what you want after the product name.
It's no small modifications, but it's possible if you're a developer.
