1、对输入信息进行验证的类(主要用于验证用户名,密码,重复密码,邮箱,可添加其它功能)
<?php /** * Validator for Register. */ final class RegisterValidator { private function __construct() { } /** * Validate the given username, password, repeat_password and email. * @param $username, $password, $repeat_password and $email to be validated * @return array array of {@link Error} s */ public static function validate($username, $password, $repeat_password, $email) { $errors = array(); $username = trim($username); $password = trim($password); if (!$username) { $errors[] = new Error('username', '用户名不能为空。'); } elseif (strlen($username)<3) { $errors[] = new Error('username', '用户名长度不能小于3个字符。'); } elseif (strlen($username)>30) { $errors[] = new Error('username', '用户名长度不能超过30个字符。'); } elseif (!preg_match('/^[A-Za-z]+$/',substr($username, 0, 1))) { $errors[] = new Error('username', '用户名必须以字母开头。'); } elseif (!preg_match('/^[A-Za-z0-9_]+$/', $username)) { $errors[] = new Error('username', '用户名只能是字母、数字以及下划线( _ )的组合。'); } elseif (!$password) { $errors[] = new Error('password', '密码不能为空。'); } elseif (strlen($password)<6) { $errors[] = new Error('password', '密码长度不能小于6个字符。'); } elseif (strlen($password)>30) { $errors[] = new Error('password', '密码长度不能超过30个字符。'); } elseif (!preg_match('/^[A-Za-z0-9!@#\\$%\\^&\\*_]+$/', $password)) { $errors[] = new Error('password', '密码只能是数字、字母或!@#$%^&*_等字符的组合。'); } elseif ($password != trim($repeat_password)) { $errors[] = new Error('password', '两次输入密码不一致。'); } elseif (!Utils::isValidEmail($email)) { $errors[] = new Error('email', '邮箱格式有误。'); } else { // check whether user exists or not $dao = new UserDao(); $user = $dao->findByName(trim($username)); if ($user) { $errors[] = new Error('username', '该用户名已经被使用。'); } $user = null; // check whether email being used or not $user = $dao->findByEmail(trim($email)); if ($user) { $errors[] = new Error('email', '该邮箱已被注册。'); } } return $errors; } } ?>
2、在注册页面进行调用
$username = null; $password = null; $repeat_password = null; $email = null; $msg = ""; if (isset($_POST['username']) && isset($_POST['password']) && isset($_POST['repeat_password']) && isset($_POST['email'])) { $username = addslashes(trim(stripslashes($_POST ['username']))); $password = addslashes(trim(stripslashes($_POST ['password']))); $repeat_password = addslashes(trim(stripslashes($_POST ['repeat_password']))); $email = addslashes(trim(stripslashes($_POST ['email']))); // validate $errors = RegisterValidator::validate($username, $password, $repeat_password, $email); // validate if (empty($errors)) { // save $dao = new UserDao(); $user = new User(); $user->setEmail($email); $last_login_ip = Utils::getIpAddress(); $user->setLastLoginIp($last_login_ip); $user->setUsername($username); $salt = substr(sha1(mt_rand()), 0, 22); $hash_password = sha1($salt . $password); $user->setPassword($hash_password); $user->setSalt($salt); $user = $dao->save($user); if ($user) { UserLogin::setUserInfo($user); Flash::addFlash('注册成功!'); } else { Flash::addFlash('对不起,由于服务器内部错误,导致注册失败。请稍后再试。'); } Utils::redirect('welcome'); } foreach ($errors as $e) { $msg .= $e->getMessage()."<br>"; }
3.代码中Error类用于记录验证时的错误信息
<?php /** * Validation error. */ final class Error { private $source; private $message; /** * Create new error. * @param mixed $source source of the error * @param string $message error message */ function __construct($source, $message) { $this->source = $source; $this->message = $message; } /** * Get source of the error. * @return mixed source of the error */ public function getSource() { return $this->source; } /** * Get error message. * @return string error message */ public function getMessage() { return $this->message; } } ?>
