Need Amazon Native Shopping ads code to programmatically drive the search results

Hi, can anyone help me with doing this? It's for a joomla website.

See "How do I programmatically drive the search results of the ad unit?" on the amazon native shopping ads faq page for the search widget.

"How do I programmatically drive the search results of the ad unit?
The ad code for Native Shopping Ads is a simple list of javascript variables and is highly programmable. To programmatically specify the search key phrase to be displayed: amzn_assoc_default_search_phrase = "your-search-phrase";
The search phrase could potentially be driven by any of the parameters available in your CMS or by the search term entered by the visitors to your site."

They give a very basic info, but it needs a detailed information and I couldn't find one when I searched online, such as where would I put the code, how I would link it up to a certain parameter, etc

Any help is appreciated.

 

Bumping this a couple of years later now because I'm hoping someone will have worked this out by now
