PHP回复不起作用

Question

Hope you guys can assist me on this. When someone completes my form I want the form I receive to have a "replyto" that implements the clients email address and not reply to the server.

So basically when I receive the from from the client I want to be able to say reply, where it shows the clients email address

Really hope you can help me on this

Answer 1

It's not clear where $from is defined, but you should be able to do:

$mail->addReplyTo($_POST['email']);

That will use your form's email address field as a reply-to address.

You've got a try/catch block, but you've not told PHPMailer to use exceptions, which you can do by passing true to the constructor:

$mail = new PHPMailer(true);

That way you don't need to throw your own exceptions. You're also using an old version of PHPMailer.
