PHPmailer's HTML Rendering Issue and its Resolution

In PHPmailer, when attempting to send HTML-formatted emails, users may encounter an unexpected problem: the actual HTML code is displayed in the email body instead of the intended content. To resolve this issue effectively, a specific order in method calls is crucial.

The proper sequencing involves setting the Body property of the PHPmailer object ($mail->Body) before calling the isHTML() method. This subtle adjustment ensures that PHPmailer recognizes the content as HTML and processes it accordingly.

Below is a corrected code snippet that addresses this issue:

$mail = new PHPMailer();

$mail->IsSMTP();                    // send via SMTP
$mail->Host     = $Host;
$mail->SMTPAuth = true;             // turn on SMTP authentication
$mail->Username = $Username;
$mail->Password = $Password;

$mail->From     = $From;
$mail->FromName = $FromName;

$mail->AddAddress($To, $ToName);

$mail->WordWrap = 50;               // set word wrap
$mail->Priority = 1;
$mail->Subject = $Subject;
$mail->Body    = $Body;
$mail->IsHTML(true);       // Call IsHTML() after $mail->Body has been set.

By following this proper sequence, PHPmailer can accurately parse and render HTML content, delivering the intended email format.
