在新用户注册时发送激活电子邮件

Question

The code below is a login system that I am using. 下面的代码是我正在使用的登录系统。 It is supposed to allow a new user to register and then send the new user an activation email. 它应该允许新用户注册，然后向新用户发送激活电子邮件。 It is inserting the new user into the MySQL database, but it is not sending the activation email. 它将新用户插入MySQL数据库，但它没有发送激活电子邮件。 Any ideas why it's not sending the activation email? 任何想法为什么它不发送激活邮件？

Thanks in advance, 提前致谢，

Thank you for registering on http://www.$domain/,

Your account information:

username:  $username
password:  $password

Please click the link below to activate your account.

$link

Regards
$domain Administration
";

    if (sendMail($email, "Please activate your account.", $message, "no-reply@$domain"))
    {
        return true;
    } else
    {
        return false;
    }
}

Answer 1

Maybe because the function for sending email is mail and not sendMail? 也许是因为发送电子邮件的功能是邮件而不是sendMail？ If the function sendMail is defined maybe there is an error in that function. 如果定义了函数sendMail，则该函数可能存在错误。

Answer 2

if (mail($email, "Please activate your account.", $message, "no-reply@$domain"))
{
    return true;
} else
{
    return false;
}

Answer 3

In addition to needing to use the mail function as mentioned by others, which is your primary problem, there is a small problem with this: 除了需要使用其他人提到的mail功能（这是您的主要问题）之外，还有一个小问题：

"no-reply@$domain"

PHP is expecting a header: PHP期待一个标题：

"From: no-reply@$domain"

or 要么

"Reply-To: no-reply@$domain"

This isn't the reason your script is failing (as mentioned above, it's using the wrong function), but it is still important to comply with the standards or else things may break when you don't expect them to. 这不是您的脚本失败的原因（如上所述，它使用了错误的功能），但遵守标准仍然很重要，否则当您不期望它们时可能会中断。
