password_hash not updating when submit form - php

Question

When I submit my form if password fields are submitted it should update the password else if empty does not update password.
I cannot seem to get the password_hash to update very strange. I can create new users fine with it but not update there password.
All other post are working fine update fine.
Not sure why password not updating? How am I able to fix issue thanks in advance.
<?php
class Model_user extends CI_Model {
public function edit_user($user_id, $data) {
$data = array(
'username' => $data['username'],
'user_group_id' => $data['user_group_id'],
'firstname' => $data['firstname'],
'lastname' => $data['lastname'],
'email' => $data['email'],
'image' => $data['image'],
'status' => $data['status']
);
$this->db->set($data);
$this->db->where('user_id', $user_id);
$this->db->update($this->db->dbprefix . 'user');
if ($data['password']) {
$options = [
'cost' => 11,
'salt' => mcrypt_create_iv(22, MCRYPT_DEV_URANDOM),
];
$data = array(
'password' => password_hash($_POST['password'], $options)
);
$this->db->set($data);
$this->db->where('user_id', $user_id);
$this->db->update($this->db->dbprefix . 'user');

Answer 1

Take a closer look at the edit_user function. You receive $data but you immediately overwrite it. Please note that you don't set a password key to the newly created array. Then you check if ($data['password']) but that will never be true therefore the update will never be done.

Answer 2

There is a problem in your password_hash($_POST['password'], $options).
You passed $_POST['password'] instead of $data['password'].

Answer 3

It took me a while to figure it out I needed to create another variable out side of the if statement in my model like below and then was able to update if new password present.
All working now.
$input_password = $this->input->post('password');
if ($input_password) {
$password = password_hash($input_password, PASSWORD_BCRYPT);
$data_password = array(
'password' => $password
);
$this->db->where('user_id', $user_id);
$this->db->update($this->db->dbprefix . 'user', $data_password);
}
