How Can I Handle PHPMailer Errors Without Direct Browser Output?

Error Handling with PHPMailer: Silencing Direct Error Echo

When utilizing PHPMailer, error handling can be a bit tricky. PHPMailer displays errors directly in the browser, which interferes with custom error handling.

The $mail->Send() method is used to send the email. Upon failure, it sets the $mail->ErrorInfo property and returns false. However, PHPMailer also echoes the error message, which can disrupt error handling.

Solution:

PHPMailer allows for error handling using exceptions. By setting the PHPMailer constructor to true, the library will throw exceptions on errors. Here's how you can do it:

require_once '../class.phpmailer.php';

$mail = new PHPMailer(true); //throws exceptions on errors

try {
    // ... Set up the email as usual ...
    
    if ($mail->Send()) {
        echo "Email successful";
    }
} catch (phpmailerException $e) {
    echo $e->errorMessage(); //PHPMailer error message
} catch (Exception $e) {
    echo $e->getMessage(); //Generic error message
}

This approach separates error handling from the actual sending process, ensuring that any errors are managed gracefully without affecting the user experience.
