PHPMailer：您必须至少提供一个收件人电子邮件地址

Question

I'm using PHPMailer on my website, but it returns an error:

You must provide at least one recipient email address.

The server is running PHP 7. I've checked out the following pages looking for answers:

• PHP Mailer You must provide at least one email address
• PHP Mailer Error: Mailer Error - must provide at least one recipient email address
• https://github.com/PHPMailer/PHPMailer/issues/441
• https://github.com/PHPMailer/PHPMailer/issues/429

None of those solved my problem.

This is the way it's set up:

require_once 'lib/phpmailer/PHPMailerAutoload.php';

$m = new PHPMailer;

$m->isSMTP();
$m->SMTPAuth = true;
$m->SMTPDebug = 2;

$m->Host = 'smtp.zoho.com';
$m->Username = '[e-mail]';
$m->Password = 'password';
$m->SMTPSecure = 'ssl';
$m->Port = 465;

$m->From = '[e-mail]';
$m->FromName = 'Name';

$m->Subject = 'Testing PHPMailer';
$m->Body = 'Body of the email. Testing PHPMailer.';

if (!$m->send()) {
    echo 'Mailer Error: ' . $m->ErrorInfo;
} else {
    echo 'Everything OK.';
}

Doing var_dump(PHPMailer::validateAddress('[e-mail]')); returns true. So the email address doesn't seem to be the issue.

EDIT

Adding $m->AddAddress = [e-mail] doesn't solve the issue. It returns the exact same error.

EDIT 2

Have added $m->addAddress('[e-mail]') to the code. I had been doing that wrong. It now returns a 500 error.

EDIT 3

Turns out I mistyped the addAddress in my code (I misplaced a quote, which caused the 500 error). The provided answer stands. I did not properly add a recipient.

My apologies for troubling you with this. I should've more carefully looked at the PHPMailer example provided, instead of blindly following a third part tutorial.

Answer 1

You haven't added a recipient address. You need to do this:

$m->addAddress('[e-mail]');

Take a look at PHPMailer's example:
