Model not updating correct - php

Question

When I update my database row. It for some reason update all the values as the same as last input which is very strange.
How can I get it working so all rows do not get updated with the value all the same?
This is how my database works.
$group = 'config'.
$key = example:'config_name'.
$value = what ever is typed in $key.
In my model I use foreach ($data as $key => $value) { It is very strange that it updates all values with the last input value.
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Model_website_setting extends CI_Model {
public function editWebsite($group , $data, $website_id = 0) {
foreach ($data as $key => $value) {
// Make sure only keys belonging to this group are used
if (substr($key, 0, strlen($group)) == $group) {
if (!is_array($value)) {
$this->db->set('group', $group);
$this->db->set('value', $key);
$this->db->set('value', $value);
$this->db->set('website_id', $website_id);
$this->db->update($this->db->dbprefix . 'setting');
} else {
$this->db->set('group', $group);
$this->db->set('value', $key);
$this->db->set('value', $value);
$this->db->set('website_id', $website_id);
$this->db->update($this->db->dbprefix . 'setting');
}
}
}
}
}
Controller
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Website_settings extends Controller {
public function __construct() {
parent::__construct();
$this->lang->load('admin/setting/setting', 'english');
}
public function index() {
$this->document->setTitle($this->lang->line('heading_title'));
$data['entry_name'] = $this->lang->line('entry_name');
$data['entry_owner'] = $this->lang->line('entry_owner');
if (!empty($this->input->post('config_name'))) {
$data['config_name'] = $this->input->post('config_name');
} else {
$data['config_name'] = $this->settings->get('config_name');
}
if (!empty($this->input->post('config_owner'))) {
$data['config_owner'] = $this->input->post('config_owner');
} else {
$data['config_owner'] = $this->settings->get('config_owner');
}
$this->load->library('form_validation');
$this->form_validation->set_rules('config_name', 'Website Name');
$this->form_validation->set_rules('config_owner', 'Your Name');
if ($this->form_validation->run() == FALSE) {
return $this->load->view('setting/website_settings', $data);
} else {
$this->load->model('admin/setting/model_website_setting');
$this->model_website_setting->editWebsite('config', $this->input->post());
$this->session->set_flashdata('success', 'You have updated settings!');
redirect('admin/setting/website');
}
}
}

If i were you i would use the built in update_batch and will not place an update on every loop.
foreach ($data as $key => $value) {
// Make sure only keys belonging to this group are used
if (substr($key, 0, strlen($group)) == $group) {
if (!is_array($value)) {
// this is where you do the logic
// if the value is the same do not insert in the update array
// if the value is not the same then insert it on the update array
$update[] = array(
'group' => $group,
'value' => $key,
'website_id' => $website_id
);
} else {
$update[] = array(
'group' => $group,
'value' => $key,
'website_id' => $website_id
);
}
}
}
$this->db->update_batch($this->db->dbprefix . 'setting', $update , 'website_id');
sample on how to use update batch on your code not tested.
