title: Adding custom PHP code to BigCommerce store
body: <p>I want to add custom PHP code to my BigCommerce store. I know how to create panels and add them to pages however this only allows for HTML code. What I want to do with the code, only on specific pages ( confirmation/transaction complete ) is to generate a custom tracking pixel which needs to include the buyer's information, order information etc. Some of the information is gathered from a cookie placed elsewhere and the rest is order related.</p>
  
  <p>How, preferably without needing to create an app, can I add PHP code to my store to specific pages to get order, cookie, client information and generate redirections and also custom tracking pixels.?</p>
  
  <p>I know bigcommerce's PHP code is closed source, but is it at all possible to add PHP code of my own?</p>
