I am using the below code for my feedback form:-
<?
$fname = $_REQUEST[‘fname’] ;
$femail = $_REQUEST[‘femail’] ;
$fphone = $_REQUEST[‘fphone’] ;
$fsubject = $_REQUEST[‘fsubject’] ;
$message = $_REQUEST[‘message’] ;
require(“class.phpmailer.php”);
$mail = new PHPMailer();
$mail->IsSMTP(); // send via SMTP
$mail->Host = “mail.myweb.org”; // SMTP server
$mail->SMTPAuth = true; // turn on SMTP authentication

$mail->Username = “myweb.org”; // SMTP username
$mail->Password = “pass”; // SMTP password

$mail->From = $femail; // visitor/ sender email id
$mail->FromName = $fname; // visitor/ sender name
$mail->AddAddress("arnab.loknath@gmail.com",“Arnab”); // Write receipnt address here
//$mail->AddReplyTo("arnab.loknath@gmail.com",“Arnab”);
$mail->WordWrap = 50; // set word wrap
//$mail->AddAttachment("Path to Attachment "); // attachment
$mail->IsHTML(true); // send as HTML
$mail->Subject = “Contact mail to myweb.org”; // mail subject
$mail->Body = “<b>Mail Body:<br></b>”.$comments; // mail body as html
//$mail->AltBody = “This is the text-only body”;
if(!$mail->Send())
{
echo “Message was not sent <p>”;
echo "Mailer Error: " . $mail->ErrorInfo;
exit;
