Passing URL Querystring values from one SP Page Builder page to another page

In SP Page Builder, how do I pass values originally passed in the URL Querystring from one page to another page and later to an external "thank-you.php" page and then also save those querystring values in a MySQL Server database table? e.g Can I put the following URL in the URL field of a button on an SP Page Builder created page; https://sitename/products?utm_code=1001&name=Gert&Surname=Myburgh&utm_session=34&utm_message=SUCCESS. So the calling URL might be for example; https://sitename/landingpage/funeral?utm_code=1001&utm_session=34&utm_message=SUCCESS and then after retrieving the passed arguments from the query string I pass them further on via a button "action" on one of the SP Page Builder forms or inside the URL property field.
