在已登录用户的编码点火器中更改密码会引发错误

Question

我想更改登录用户的密码，但它总是给我一个错误：[消息：试图在控制器中获取非对象的属性"密码"]。如何解决此错误??? 请帮忙，非常感谢！

这是我的控制器：

if($this->form_validation->run()){
$cur_password = md5($this->input->post('cpassword')); // md5-encrypt the password
$new_password = md5($this->input->post('npassword'));
$conf_password = md5($this->input->post('copassword'));
//$this->load->model('queries');
$this->load->library('session');
$user_id = $this->session->userdata('user_id');//multiple users id login
$passwd = $this->queries->getCurPassword($user_id);
!ERROR FOUND HERE!->if($passwd->password == $cur_password){
if($new_password == $conf_password){
if($this->queries->updatePassword($new_password,$user_id)){
echo 'Password Updated Successfully!';
echo '<br/><label><a href="'.base_url().'main/enter">Back to homepage</a></label><br/>';
}else{
echo 'Failed To Update Password!!';
}
}else{
echo 'New Password and Confirm Password is not matching!!';
}
}else{
echo 'Sorry! Current Password is not matching!!';
}
}else{
echo validation_errors();
}

这是我的模型：

<?php
class Queries extends CI_Model{
function login() {
$query = $this->db->select('*')
->from('users')
->where('id');
return $query->row();
}
function index() {
$userid = $this->login()->id; //id of the user which is currently logged IN
$this->session->set_userdata('user_id', $user_id);
}
public function getCurPassword($user_id){   
$query = $this->db->where(['id'=>$user_id])
->get('users');
if($query->num_rows() > 0 ){
return $query->row();
}
}
public function updatePassword($new_password,$user_id){
$data = array(
//'password' => md5($this->input->post("$new_password"))
'password' => ($new_password)
//'password'=> password_hash(["$new_password"],PASSWORD_BCRYPT)
);
return $this->db->where('id',$user_id)
->update('users',$data);
}
}

谢谢！

Answer 1

你的语法错误说你正在尝试获取non-object的属性$passwd这意味着它可能是一个数组

if($passwd['password'] == $cur_password)

如果你有空user_id

将这两行放在if($this->form_validation->run()){行上方的控制器函数中

$userid = $this->queries->login()->id; //id of the user which is currently logged IN
$this->session->set_userdata('user_id', $userid);

并在模型中的登录功能

function login() {
$query = $this->db->select('*')
->from('users')
->where('username',$this->session->userdata('username'));
return $query->row();
}

希望对您有所帮助！

当找不到user_id时，会发生这种情况。

请注意，如果找到用户(检查是否num_rows > 0(，getCurPassword函数将返回用户，但如果未找到，则返回NULL。

发生这种情况时，$passwdvar 为空，因此您无法访问$passwd->password。

您可以通过将if语句更改为：

if($passwd && $passwd->password == $cur_password){

已编辑尝试检索您的用户名，然后使用它调用getCurPassword函数：

$user_name = $this->session->userdata('username');
$passwd = $this->queries->getCurPassword($user_name );

并在控制器中更改getCurPassword功能为：

public function getCurPassword($user_name){   
$query = $this->db->select('*')
->from('users')
->where('username', $user_name);
if($query->num_rows() > 0 ){
return $query->row();
}
}

请注意，我假设您的数据库中有"用户名"列
