Question

作为一名设计师，我不熟悉PHP + MySQL。对于我们的一个项目，我们创建了一个“重置密码”功能，该功能通过电子邮件将新密码发送给用户。由于我们用户的反馈，我们也想在此电子邮件中添加用户名。

这是我们目前使用的代码：

class password {

private $newpassword;
private $passwordlength = 10;

function __construct() {
    $this->newpassword = $this->getRandomPassword($this->passwordlength);
}

// This function resets the password
function resetPassword($email) {
    mysql_query("UPDATE users 
                    SET password = '".md5($this->newpassword)."' 
                        WHERE email = '".mysql_real_escape_string($email)."'") 
                            or die(mysql_error());
    $this->sendNewPassword($email);
}


// Check if email is exists
function checkEmailAdress($email) {
    $correctemail = false;

    $queryEmail = mysql_query("SELECT username FROM users 
                        WHERE email = '".mysql_real_escape_string($email)."'")
                            or die(mysql_error());

    if(mysql_num_rows($queryEmail) == 1) {
        $correctemail = true;
    }
    return $correctemail;
}

// Send new password with email
function sendNewPassword($email) {

    $onderwerp = 'New password for ... ';

    $headers  = 'MIME-Version: 1.0' . "\r\n";
    $headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
    $headers .= 'From: info@domain.com' . "\r\n" .
        'Reply-To: info@domain.com' . "\r\n" .
        'X-Mailer: PHP/' . phpversion();

    $bericht = '<div>
                    Your new password is: '.$this->newpassword.'
                </div>

                <div>
                    Your username is: USERNAME HERE.
                </div>

                '; 

    mail($email, $onderwerp, $bericht, $headers);
}

// Generate random password
function getRandomPassword($length) {
    $characters = "0123456789abcdefghijklmnopqrstuvwxyz";
    $string = "";    

    for ($p = 0; $p < $length; $p++) {
        $string .= $characters[mt_rand(0, strlen($characters))];
    }
    return $string;
}

}

用户名存储在表'username'中。

如何检索用户名并将其添加到'$ bericht'（消息）

中

在您的功能中添加此

function resetPassword($email) {
    mysql_query("UPDATE users 
                SET password = '".md5($this->newpassword)."' 
                    WHERE email = '".mysql_real_escape_string($email)."'") 
                        or die(mysql_error());
    $result = mysql_query("SELECT username as username FROM users 
                    WHERE email = '".mysql_real_escape_string($email)."'") 
                        or die(mysql_error());
    $my_res = mysql_result($result); 
    $username = $my_res[0]['username'];
    $this->sendNewPassword($email,$username);
}

并在您的邮件中添加

$bericht = '<div>
                Dear User: '.$username.'
            </div>

             <div>
                Your new password is: '.$this->newpassword.'
            </div>

            <div>
                Your username is: USERNAME HERE.
            </div>

            ';
