When an email user licks a link in an email that take them to a web form, how do u prefill the form with the user email add?

Question

php, php mail, php form,

Answer 1

A couple ways at least; it could be sent along as a URL variable from an anchor in an HTML email:

<a href="//www.example.com?email=[e-mail]">click here</a>

but you can also send a unique string:
... www.example.com?prospectID=1234567890

and then PHP would look up prospectID 1234567890 in a database.

In either case, PHP would echo/insert the sent or retrieved value into its output when generating a response to the click.
