我的表单验证错误停止工作，昨天还在工作，我一定做错了什么，但似乎找不到。
当我填写用户名和电子邮件地址时，它会发送电子邮件并回显“电子邮件已发送！”。
当我只是单击注册而不填写任何信息时，它只会重定向到加载视图的用户/注册。
控制器/user.php：
public function signup_validation() {
$this -> load -> library('form_validation');
$this -> form_validation -> set_rules('username', 'Username', 'trim|required|alpha|min_length[3]|max_length[25]');
$this -> form_validation -> set_rules('email', 'Email', 'required|trim|valid_email|is_unique[users.email]');
$this -> form_validation -> set_rules('password', 'Password', 'required|trim');
$this -> form_validation -> set_rules('cpassword', 'Retype', 'required|trim|matches[password]');
if ($this -> form_validation -> run()) {
$key = md5(uniqid());
$this -> load -> library('email', array('mailtype' => 'html'));
$this -> load -> model('users');
$this -> email -> from('', "");
$this -> email -> to($this -> input -> post('email'));
$this -> email -> subject('Confirm your account.');
$message = "<p>Thank you for signing up!</p>";
$message = "<p><a href='" . base_url() . "user/activate/$key'>Click here</a> to confirm your account.</p>";
$this -> email -> message($message);
if ($this -> users -> add_temp_user($key)) {
if ($this -> email -> send()) {
echo "The email has been sent!";
} else {
echo "Could not send the email.";
}
} else {
echo "Problem adding user to database.";
}
} else {
redirect('user/signup');
}
}
