您好:我需要在登录页面上实现忘记密码。在这里,我解释了到目前为止我所拥有的
email_exists()
将验证电子邮件。如果是,send_email()
带有$temp_pass
密钥和链接。数据库将存储$ temp_pass以进行进一步操作和验证。$temp_pass
发送到功能reset_password的链接。$temp_pass
。如果是这样,加载视图以输入新密码 - 这就是我被卡住的地方,因为表单指向一个无法识别$temp_pass
因此无法重置密码的控制器。如何检索与正确用户关联的新密码并重置密码?
以下代码:
public function recover(){
//Loads the view for the recover password process.
$this->load->view('recover');
}
public function recover_password(){
$this->load->library('form_validation');
$this->form_validation->set_rules('email', 'Email', 'required|trim|xss_clean|callback_validate_credentials');
//check if email is in the database
$this->load->model('model_users');
if($this->model_users->email_exists()){
//$them_pass is the varible to be sent to the user's email
$temp_pass = md5(uniqid());
//send email with #temp_pass as a link
$this->load->library('email', array('mailtype'=>'html'));
$this->email->from('user@yahoo.com', "Site");
$this->email->to($this->input->post('email'));
$this->email->subject("Reset your Password");
$message = "<p>This email has been sent as a request to reset our password</p>";
$message .= "<p><a href='".base_url()."main/reset_password/$temp_pass'>Click here </a>if you want to reset your password,
if not, then ignore</p>";
$this->email->message($message);
if($this->email->send()){
$this->load->model('model_users');
if($this->model_users->temp_reset_password($temp_pass)){
echo "check your email for instructions, thank you";
}
}
else{
echo "email was not sent, please contact your administrator";
}
}else{
echo "your email is not in our database";
}
}
public function reset_password($temp_pass){
$this->load->model('model_users');
if($this->model_users->is_temp_pass_valid($temp_pass)){
$this->load->view('reset_password');
}else{
echo "the key is not valid";
}
}
public function update_password(){
$this->load->library('form_validation');
$this->form_validation->set_rules('password', 'Password', 'required|trim');
$this->form_validation->set_rules('cpassword', 'Confirm Password', 'required|trim|matches[password]');
if($this->form_validation->run()){
echo "passwords match";
}else{
echo "passwords do not match";
}
}
public function email_exists(){
$email = $this->input->post('email');
$query = $this->db->query("SELECT email, password FROM users WHERE email='$email'");
if($row = $query->row()){
return TRUE;
}else{
return FALSE;
}
}
public function temp_reset_password($temp_pass){
$data =array(
'email' =>$this->input->post('email'),
'reset_pass'=>$temp_pass);
$email = $data['email'];
if($data){
$this->db->where('email', $email);
$this->db->update('users', $data);
return TRUE;
}else{
return FALSE;
}
}
public function is_temp_pass_valid($temp_pass){
$this->db->where('reset_pass', $temp_pass);
$query = $this->db->get('users');
if($query->num_rows() == 1){
return TRUE;
}
else return FALSE;
}

我不太确定你被困在哪里。我可以得到一个事实,即您正在为用户创建一个临时标志,您可以在用户单击链接时验证该标志。因此,这意味着,您可以在此时开始会话,并且只有在特定会话处于活动状态时,用户才能重置密码。
在此步骤之后,您要求用户输入他的新密码,因为您有一个临时标志,您为该用户调用$temp_pass
(请注意它应该是唯一的),那么您可以找到试图重置密码的用户。
因此,您需要做的就是运行此类数据库查询 -
$this->db->where('reset_pass', $temp_pass);
$this->db->update('users', $data); // where $data will have the fields with values you are updating
另外,我刚注意到你的recover_password()
函数 -
$message .= "<p><a href='".base_url()."main/reset_password/$temp_pass'>Click here </a>if you want to reset your password, if not, then ignore</p>";
上述行不应该是 -
$message .= "<p><a href='".base_url()."main/reset_password/".$temp_pass."'>Click here </a>if you want to reset your password, if not, then ignore</p>";
您可以将$temp_pass
传递到会话中并从那里检索。这是解决问题的一种方法。

我想建议您对密码重置程序进行一些改进。
md5(uniqid())
可能会严重缩小。我发布了一些example code,这样的密码重置过程可能是什么样子,以及一个可以生成安全令牌的类。
