PHPMailer 包含 PHP 模板在电子邮件中返回 1

Question

我在一个电子邮件模板上，该电子邮件模板将是基于动态的。所以我将模板制作为 PHP 文件，并在 PHP 中使用 INCLUDE 函数包含内容。电子邮件通过了，但我在电子邮件中收到 1。

PHP

ob_start();
$preview_contents = include( get_template_directory() . '/framework/newsletters/includes/preview.php' );
$content = ob_get_contents();
ob_end_clean();

PHPMAILER

    $mail = new PHPMailer();
    $mail->IsSMTP();
    $mail->IsHTML(true);
    $mail->SMTPAuth   = true;
    $mail->Host       = $host;
    $mail->Username   = $username;
    $mail->Password   = $pass;
    $mail->SetFrom("no-reply@xxxxx.com", "Pacific xx");
    $mail->AddAddress($subscribers_preview_email);
    $mail->Subject = $subscribers_subject;
    $mail->MsgHTML($preview_contents);
    if($mail->Send()){
        die("1 | An preview email has been sent to you.");
    } else {
        die("0 | There was an error, please try again later.");
    }

您需要更改这部分代码

$mail->MsgHTML($preview_contents);

看起来像这样

$mail->MsgHTML($content);

我认为这对你有用
