title: Opencart - How I can execute a custom code on product page? Without mods on controller product
body: <p>I'm working on a Custom Mod for OpenCart.</p>
  <p>I want to populate the Product page when the customer opens it via a link.</p>
  <p>I don't want to touch the MVC controller etc - can I just make an Ajax Call or do PHP inside the View?</p>
