Display Query String Parameters

[questioner18]

I am trying to figure out how to display the query string parameters that are passed along with purchase on my wordpress website. I am fairly new to html and php but not a complete novice. I do not understand javascript.



A previous thread suggested searching for javascript + query string parameters. I've spent about three hours and have not come across a solution that shows any sign of working. Most explain how to parse the query string but there is not explanation of how to display the variables on the webpage.



In addition, some solutions use php but that requires changing page templates in wordpress. It seems that there has to be some simple code that will allow me to read the variables from the URL and display them on the webpage in various forms.



Can someone help steer me in the right direction on this?

Perhaps studying a specific example may help get you on the right track. This page provides some example PHP to parse the value of 'txn_id' from the page URL's query string on every visit, and then output that value as part of an IFRAME src= URL in the page body itself:
