In this example we using Models, Views, Controller Structure for Changing password in the database.
To change password in the database first we have to create a view page.
views/changepassword/changepassword.php
<!DOCTYPE html>
<html>
<body>
<form action="<?php echo URL; ?>changepassword/submit_changepassword" method="post">
<input type="text" name="oldpassword" id="oldpassword" placeholder="Enter Your Old Password"><br>
<input type="text" name="newpassword" id="newpassword" placeholder="Enter Your New Password"><br>
<input type="text" name="confirmpassword" id="confirmpassword" placeholder="Enter Confirm Password"><br>
<span id='message'></span>
<input type="hidden" value="<?php echo Session::get('id'); ?>" name="id">
<button type="submit" value="submit" name="submit" style="background-color:#008000">Submit</button>
</form>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script>
$('#newpassword, #confirmpassword').on('keyup', function () {
if ($('#newpassword').val() == $('#confirmpassword').val()) {
$('#message').html('Matching').css('color', 'green');
} else
$('#message').html('Not Matching').css('color', 'red');
});
</script>
Here is the model file which we are using for Change Password.
The file changepassword_model.php is created under Models folder
models/changepassword_model.php
<?php
class Changepassword_model extends Model
{
public function __construct()
{
parent::__construct();
}
public function changepassword($data,$arg)
{
$this->db->update('register', $data,"`id` = $arg");
}
public function error($msg)
{
return '<div id="error">'.$msg.'</div>';
}
}
?>
Here is the Controller file changepassword.php which inside controllers folder
controllers/changepassword.php
<?php
class Changepassword extends Controller
{
public function __construct()
{
parent::__construct();
Session::init();
}
function changepassword() {
$this->view->render('changepassword/changepassword');
}
function submit_changepassword() {
if(md5($_POST['oldpassword'])==Session::get('password')){
$arg=$_POST['id'];
$data=array(
'password'=>md5($_POST['confirmpassword'])
);
$this->model->changepassword($data,$arg);
$this->view->msg = $this->model->error("Your Password is updated Successfully.");
}
else{
$this->view->msg = $this->model->error("You Entered an Invalid Password.");
}
}
}
?>
