email - PHP mail function 'from' address

Question

I'm not even sure this is possible, however what I'm trying to do is as follows. I have an HTML form that generates and email using a PHP script. What I want is to recieve emails from this form to [email protected], then I want the from address to appear as one of the fields in the form.

I have had a look around and found some useful information on this site. I'm not sure whether sendmail_from can be used in this situation, or if it does what I'm asking.

Is this possible, if so how?

Answer 1

See this page on the same site (example 2): http://www.w3schools.com/php/func_mail_mail.asp

You will have to set the headers of the message to include the From and other stuff like CC or BCC:

<?php
$to = "[email protected]";
$subject = "My subject";
$txt = "Hello world!";
$headers = "From: [email protected]
";

mail($to,$subject,$txt,$headers);
?>

Note that you have to separate the headers with a newline sequence " ".
