I’d like to know how to read mtm parameters in php, but not from querystring. Why?
For example, a visitor enters my website from a link like this: https://agenziaimmobiliare.website/?mtm_campaign=test
The user fillup a form and send an email. In the email I’d like to have the mtm_campaign parameter, so I exactly know from which campaign the email is from. I can do this reading querystring url with php. No problem.
The real problem is that if the user browse other pages, mtm_campaing parametrer disappears from url and I cannot read it to write it in the email. Are there some session variables to read?
