PhPMailer - 您必须提供至少一个收件人电子邮件地址 - 但无论如何都要发送邮件

Question

I've got a PHPMailer setup which works fine, but when I added BCC it begins to report error. I can't see what exactly causing this issue.

I've got this error report: You must provide at least one recipient email address.

The strange thing is, that it's sending the emails correctly to both recipients but never changes to my 'succes.php'-page. It just simply showing the error reporting.

I have tried almost any combination of ADD and Clear, but keep getting somekind of issue. What I'm facing now, does sends the emails, but still reporting error.

My setup is like this:

    try {
        // Ens for all
        $mail->Host       = 'localhost'; // SMTP server
        $mail->AddReplyTo('[e-mail]', 'XXX Mailer');
        $mail->AltBody = 'To view the message, please use an HTML compatible email viewer!'; 
        $mail->AddAddress("$email");
        $mail->AddBCC("$bcc");
        $mail->Subject = "$subject";
        $mail->MsgHTML($message);
        $mail->Send();
        $mail->ClearBCCs();
        $mail->ClearAddresses();
        if(!$mail->Send()) {
            header('Location: fejl.php');
        } else { 
            header('Location: succes.php');
        }

    } catch (phpmailerException $e) {
      echo $e->errorMessage(); //Pretty error messages from PHPMailer
    } catch (Exception $e) {
      echo $e->getMessage(); //Boring error messages from anything else!
    }
} // end of if !mail

else { //report the errors
    echo 'TEST ERRORS';
    foreach ($errors as $msg) { //prints each error
        echo " - $msg<br />
";;
    } // end of foreach
    echo 'End';
} //end of if(empty($errors))

Basic error:

    $mail->Send();
    $mail->ClearBCCs();
    $mail->ClearAddresses();
    if(!$mail->Send()) {

You're calling send(), removing all the addresses, then calling send() again, hence the error.

You've also based your code on an old, obsolete example, so you're probably running an old version of PHPMailer. Get the latest.
