I have a problem in putting error message for the status of enrollment for student whether he/she Old Student, New Student, Transferee. When I input or add again the status of student, it will error due to duplicate entry because it is one-to-one relationship, so I need to set a message such as form validation but still it will error duplicate entry.
here is the picture:
here is my controller:
function enrollstudent(){
if($this->session->userdata('logged_in'))
{
$this->output->set_header('Expires: Sat, 26 Jul 1997 05:00:00 GMT');
$this->output->set_header('Cache-Control: no-cache, no-store, must-revalidate, max-age=0');
$this->output->set_header('Cache-Control: post-check=0, pre-check=0', FALSE);
$this->output->set_header('Pragma: no-cache');
$session_data = $this->session->userdata('logged_in');
$data['Username'] = $session_data['Username'];
$this->load->view('StudentEnroll', $data);
} else{
redirect('welcome', 'refresh');
}
if((!isset($session_data) || $session_data !=TRUE)) {
redirect('welcome', 'refresh');
}
}
function addstatusofenroll($id){
$this->form_validation->set_rules('status', 'Status', 'callback_status_check');
if($this->form_validation->run() == FALSE)
{
$this->enrollstudent();}
else{
$data= array(
'Id'=> $id ,
'Statusofenrollment' => $this->input->post('status')
);
$this->db->insert('statusofenrollment',$data);
$this->session->set_flashdata('category_success', 'Successfully Add!');
$this->load->view('StudentEnroll');
}
}
public function callback_status_check($roll)
{
$this->db->where('Id', $roll);
$query = $this->db->get('statusofenrollment');
$count_row = $query->num_rows();
if ($count_row > 0)
{
echo 'Data Already exist';
$this->session->set_flashdata('warning', 'Data already exists');
return FALSE;
}
else
{
return TRUE;
}
}
It sounds like the status shouldn't be a one-to-one relationship because there can be many students with the same status. If you change your database so the status field does not need to be unique, you should be able to insert and update each student freely.

Is there any solution how to make change password for logged in user? i want to make a change password for logged in user, the code i made only change user password with user id number 1. it doesn't change for logged in user. so any idea?
this is my controller:
public function update(){
$this->form_validation->set_rules('password', 'Current Password', 'required|alpha_numeric|min_length[6]|max_length[20]');
$this->form_validation->set_rules('newpass', 'New Password', 'required|alpha_numeric|min_length[6]|max_length[20]');
$this->form_validation->set_rules('confpassword', 'Confirm Password', 'required|alpha_numeric|min_length[6]|max_length[20]');
if($this->form_validation->run()){
$cur_password = $this->input->post('password');
$new_password = $this->input->post('newpass');
$conf_password = $this->input->post('confpassword');
$this->load->model('queries');
$userid = '1';
$passwd = $this->queries->getCurrPassword($userid);
if($passwd->password == $cur_password){
if($new_password == $conf_password){
if($this->queries->updatePassword($new_password, $userid)){
echo 'Password updated successfully';
}
else{
echo 'Failed to update password';
}
}
else{
echo 'New password & Confirm password is not matching';
}
}
else{
echo'Sorry! Current password is not matching';
}
}
else{
echo validation_errors();
}
This is my model:
public function getCurrPassword($userid){
$query = $this->db->where(['id'=>$userid])
->get('users');
if($query->num_rows() > 0){
return $query->row();
} }
public function updatePassword($new_password, $userid){
$data = array(
'password'=> $new_password
);
return $this->db->where('id', $userid)
->update('users', $data); }
You can initialize a session when the user logs in to the system at the beginning, and store the information of the user in that session, like this:
function login() {
$query = $this->db->select(*)
->from('table_name')
->where('your parameters....');
return $query->row();
}
function index() {
$userid = $this->login()->id; //id of the user which is currently logged IN
$this->session->set_userdata('current_userId', $userid);
}
You have now stored the id of currently logged IN user in the session. You can access the id by $this->session->userdata('current_userId');. Replace your $userid = '1' by the session data. Also, you will have to load the session library in order to do so.
My controler cod is:
function register()
{
if(isset($_POST['register'])){
$this->form_validation->set_rules('username','Username','required');
$this->form_validation->set_rules('email','Email','required');
$this->form_validation->set_rules('password','Password','required');
//
if($this->form_validation->run () == true){
echo 'Form Validate';
$data = array(
'username'=>$_POST['username'],
'email'=>$_POST['email'],
'password'=>strtoupper(hash('whirlpool',$_POST['password']))
);
$this->db->insert('accounts',$data);
$this->load->model("usuarios_model");
if($this->usuarios_model->check_user_exist($data['username'])){
echo "already user exist";
}{
$this->db->insert('accounts',$data);
redirect("painel/index");
}
}
}
$this->load->view("painel/register");
}

It registers an user even though the username already exists.
Where is the mistake?
You can use is_unique rule in your form_validation library.
$this->form_validation->set_rules('username','Username','required|is_unique[table.column]');
You have mistake in your model in where condition it will be small later of username but you used Username.
use this code in your model.
function check_user_exist($username){
$this->db->wehre('username',$username);
$this-db->from('accounts');
$query= $this->db->get();
if($query->num_rows() > 0){
return true;
}else{
return false;
}
}
and also controller data insert after user check:
if($this->usuarios_model->check_user_exist($data['username'])){
echo "already user exist";
}{
$this->db->insert('accounts',$data);
redirect("painel/index");
}
You can easily achieve this using call_back function in validation. From Codeigniter Docs
Controller
function register() {
if ($this->input->post('register')) {
$this->form_validation->set_rules('username','Username','required|callback_checkUserName');
$this->form_validation->set_rules('email','Email','required');
$this->form_validation->set_rules('password','Password','required');
//
if ($this->form_validation->run() == true) {
$data = array(
'username '=> $this->input->post('username'),
'email' => $this->input->post('email'),
'password' => strtoupper(hash('whirlpool', $this->input->post('password')))
);
$this->db->insert('accounts',$data);
echo 'success';
exit();
} else {
echo validation_errors(); die; // check errors
}
}
$this->load->view("painel/register");
}
// call back validate function
function checkUserName($userName){
if ($this->usuarios_model->checkUserexist($userName) == false) {
return true;
} else {
$this->form_validation->set_message('checkUserName', 'This userName already exist!');
return false;
}
}
MODEL
function checkUserexist($userName) {
$this->db->where('username', $userName);
$this-db->from('accounts');
$query = $this->db->get();
if ($query->num_rows() > 0) {
return true;
}
return false;
}
This my code which I used in one of my projects replace the words with your code:
$this->form_validation->set_rules('companyname','Company Name','trim|required|callback_companyname_exist');
Here is above callback function:
function companyname_exist($str) {
$this->db->where('company_name', $str);
$this->db->where('user_type','Shop');
$prod = $this->db->get('grs_user');
if ($prod->row()) {
$this->form_validation->set_message('companyname_exist', 'This Company name is already Available.');
return FALSE;
} else
return TRUE;
}
You can used this for already register email check also.
i have code like this
my model:
function get_status()
{
$nik=$this->session->userdata('nik');
$this->db->select('*');
$this->db->where('nik',$nik);
$this->db->from('t_trx_activity');
$query= $this->db->get();
return $query->result();
}
my controller:
public function input()
{
$status = $this->activity->get_status();
if ($status->status ==1) {
redirect ('activity');
} else {
$data = array(
'title' => 'Activity',
'breadcrumb'=> 'Input Activity'
);
$this->load->view ( 'default', $data );
}
}
my problem when status=1 site can access,i hope i can't access site and redirect other site.
how to prevent acccess when status=1?
What value your storing in status field in 't_trx_activity' table?
By default if your storing it is as '1' then condition is always true and it will be redirected.
I have a login and registration system in codeignitor.
This is my controller -
function index()
{
if($this->session->userdata('logged_in'))
{
$session_data = $this->session->userdata('logged_in');
//$data['username'] = $session_data['username'];
$data = array(
'user_id'=>$session_data['user_id'],
'username'=>$session_data['username'],
'firstname'=>$session_data['firstname'],
'lastname'=>$session_data['lastname']
);
$this->load->view('home_view', $data);
}
else
{
//If no session, redirect to login page
redirect('login', 'refresh');
}
}
this code only show me the user_id and username. but not showing the firstname and lastname. Please help me ...
Considering that you have set your session like this,
$data = array(
'user_id'=>id,
'username'=>"name",
'logged_in'=>1,
);
$this->session->set_userdata($data);
To access values from session,
$this->session->userdata("name of session variable");
In your case,
$this->session->userdata("user_id");// for user id
$this->session->userdata("user_name");// for user name
if($result) {
$sess_array = array();
foreach($result as $row) {
$sess_array = array(
'user_id' => $row->user_id,
'username' => $row->username
);
$this->session->set_userdata('logged_in', $sess_array);
}
return TRUE;
} else {
$this->form_validation->set_message('check_database', 'Invalid username or password');
return false;
}
In your above given code I can't find the firstname in session setting. But you are trying to get firstname then how will the code provide you the firstname.
i'm new to codeigniter, and i am attempting to create a password reset system
this is my controller:
public function changePassword(){
if($this->session->userdata('loginuser'))
{
$session_data = $this->session->userdata('loginuser');
$email = $this->session->userdata('email');
$data['email'] = $email;
$data['title'] = 'Change my Password | Watch Stop';
$this->load->view('template/header', $data);
$this->load->view('watch_stop/vpassword', $data);
$this->load->view('template/footer');
}
else
{
//If no session, redirect to login page
redirect('login', 'refresh');
}
}
public function reset_password(){
if($this->session->userdata('loginuser'))
{
$session_data = $this->session->userdata('loginuser');
$email = $this->session->userdata('email');
$data['email'] = $email;
//validating form
$this->form_validation->set_rules('old_password','Old Password','trim|required|min_length[5]|md5');
$this->form_validation->set_rules('new_password','New Password','trim|required|min_length[5]|matches[cnew_password]|md5');
$this->form_validation->set_rules('cnew_password','Confirm Password','trim|required||md5');
if ($this->form_validation->run() == FALSE)
{
$this->changePassword();
//$this->session->set_flashdata('msg','<div class="alert alert-danger text-center">Failed to update password</div>');
}else {
$query=$this->customer_model->change_password();
$data = array( "main_content" => 'includes/memberadmin/memberadmin_cpass_process',
"query" => $query
);
$this->load->view('includes/memberadmin/template',$data);
}
}
else
{
//If no session, redirect to login page
redirect('login', 'refresh');
}
}
this is my model:
function change_password(){
$this->db->select('id');
$this->db->where('email',$this->session->userdata('email'));
$this->db->where('password',$this->input->post('old_password'));
$query=$this->db->get('user');
if ($query->num_rows() > 0)

}
}else{
return "Something Went Wrong, Password Not Changed";
}
}else{
return "Wrong Old Password";
}
}
When i click on the update button in my reset password page, i am getting the following error for my new password confirmation field: Unable to access an error message corresponding to your field name Confirm Password.()
please help!
1) there are two pipe signs near required||md5
$this->form_validation->set_rules('cnew_password','Confirm Password','trim|required||md5');
change it to
$this->form_validation->set_rules('cnew_password','Confirm Password','trim|required|md5');
2) changing input to md5 at this stage is not good.
You have to use password_hash function.
Read More >> http://php.net/manual/en/function.password-hash.php
3) You forgot to load model. $this->load->model('customer_model');
