How do I AddAddress automatically in PHPmailer from form php info? - email

Question

This has got to be a simple one, but I've been searching all over and nothing seems relevant to my problem: or i'm not able to interpret advice for others adequately.
I'm getting the error "You must provide at least one recipient email address. Message could not be sent."
If I put a specific email address in 'AddAddress' field the message is sent. I want to have an email sent to the user who has submitted their form as an automatic email response thanking user for registering... Thus the ($_POST['email']) in the 'AddAddress' field. This works in Mail() php function. Why not PHP MAiler? What am I missing?
Here is my code with sensitive bits taken out (Relevant bit - I think - in bold):
<?php
$host="localhost"; // Host name
$username=""; // Mysql username
$password=""; // Mysql password
$db_name=""; // Database name
$tbl_name=""; // Table name
// Connect to server and select database.
mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db_name")or die("cannot select DB");
// Get values from form
$email=$_POST['email'];
// Insert data into mysql
$sql="INSERT INTO $tbl_name(email,) VALUES('$email',)";
$result=mysql_query($sql);
// if successfully insert data into database, displays message "Successful".
if($result){
}
else {
echo "ERROR";
}
?>
<?php
require("class.phpmailer.php");
$mail = new PHPMailer();
$mail->IsSMTP(); // set mailer to use SMTP
$mail->Host = "localhost"; // specify main and backup server
$mail->SMTPAuth = false; // turn on SMTP authentication
$mail->Username = ""; // SMTP username
$mail->Password = ""; // SMTP password
$mail->From = "";
$mail->FromName = "";
**$mail->AddAddress = ($_POST['email']);**
$mail->WordWrap = 50; // set word wrap to 50 characters
$mail->IsHTML(true); // set email format to HTML
$mail->Subject = "";
$mail->Body = "";
$mail->AltBody = "";
if(!$mail->Send())
{
echo "Message could not be sent. <p>";
echo "Mailer Error: " . $mail->ErrorInfo;
exit;
}
echo "Message has been sent";
?>
<?php
// close connection
mysql_close();
?>
Many thanks in advance for your advice. Hopefully this will help others too...

Simple one... just change this line
$mail->AddAddress = ($_POST['email']);
to this:
$mail->AddAddress($_POST['email']);
as it is a method, as opposed to a variable, on the class! :)
there are some good examples you can use on the PHPMailer GitHub
