我有这段代码,但是当我尝试对 db 进行第二次查询时它崩溃了,为什么?这是代码的一部分,它崩溃了
if ($this->doRegister === true) {
$db = DB::connect();
$stmt = $db->prepare('SELECT `user_id` FROM `users` WHERE `user_name` = ? OR `user_email` = ? LIMIT 1');
$stmt->bind_param('ss', $this->store['userData']['name'], $this->store['userData']['email']);
$stmt->execute();
$stmt->bind_result($userId);
$stmt->fetch();
if (is_numeric($userId)) {
$stmt = $db->prepare('INSERT INTO `users`(`user_name`, `user_password`, `user_email`, `user_ip`, `user_dateRegistered`, `user_type`) VALUES (?, ?, ?, ?, ?, ?)');
$hashedPassword = $this->encrytion('md5', md5($this->store['userData']['name']) . md5($this->store['userData']['password']));
$dateRegistered = time();
$type = 1;
$stmt->bind_param('ssssii', $this->store['userData']['name'], $hashedPassword, $this->store['userData']['email'], $_SERVER['REMOTE_ADDR'], $dateRegistered, $type);
$stmt->execute();
$this->registerUser();
} else {
return array('register' => 'User name or email already exists');
}
} else {
return $this->store['userDataState'];
}
