Fetch and Update Data in same page CodeIgniter - php

Question

I got stuck in a a problem in which I need to update some info from database in the same page that is shown.
On this case I'm fetching some "global settings" from a website in an index page which comes with a form in it. Here is a picture of it just to make it more clear to understand what I mean.
As you can see I created the button and I made it possible to see the values from the database, the problem is that I can not figure it out how to update it from there. Can somebody suggest an idea?
Here is my controller:
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Settings extends Admin_Controller {
public function index()
{
$this->form_validation->set_rules('website_favicon', 'Favicon', 'trim|required|min_length[4]');
$this->form_validation->set_rules('website_logo', 'Logon', 'trim|required|min_length[4]');
$this->form_validation->set_rules('website_name', 'Website Name', 'trim|required|min_length[4]');
$this->form_validation->set_rules('website_credits', 'Credits', 'trim|required|min_length[4]');
$this->form_validation->set_rules('website_credits_link', 'Credits Link', 'trim|required|min_length[4]');
$this->form_validation->set_rules('website_copyright', 'Copyright', 'trim|required|min_length[4]');
if($this->form_validation->run() == FALSE){
// Get Current Subject
$data['item'] = $this->Settings_model->get_website_data();
//Load View Into Template
$this->template->load('admin', 'default', 'settings/index', $data);
} else {
// Create website settings
$data = array(
'website_favicon' => $this->input->post('website_favicon'),
'website_logo' => $this->input->post('website_logo'),
'website_name' => $this->input->post('webiste_name'),
'website_credits' => $this->input->post('website_credits'),
'website_credits_link' => $this->input->post('website_credits_link'),
'website_copyright' => $this->input->post('website_copyright'),
);
// Update User
$this->Settings_model->update($id, $data);
// Activity Array
$data = array(
'resource_id' => $this->db->insert_id(),
'type' => 'website settings',
'action' => 'updated',
'user_id' => $this->session->userdata('user_id'),
'message' => 'User (' . $data["username"] . ') updated the website settings'
);
// Add Activity
$this->Activity_model->add($data);
//Create Message
$this->session->set_flashdata('success', 'Website setting has been updated');
//Redirect to Users
redirect('admin/settings');
}
}
}
Here is my model:
<?php
class Settings_model extends CI_MODEL
{
function __construct()
{
parent::__construct();
$this->table = 'website_settings';
}
public function update($id, $data)
{
$this->db->where('id', $id);
$this->db->update($this->table, $data);
}
public function get_website_data()
{
$this->db->select('*');
$this->db->from($this->table);
$this->db->where('id', 1);
$this->db->limit(1);
$query = $this->db->get();
if ($query->num_rows() == 1) {
return $query->row();
} else {
return false;
}
}
}
and here is my view(index.php) with the form:
<h2 class="page-header">Website Settings</h2>
<?php if($this->session->flashdata('success')) : ?>
<div class="alert alert-success alert-dismissible">
<button type="button" class="close" data-dismiss="alert" aria-hidden="true">×</button>

Thanks for helping.

Answer 1

Check if the data is posted thru the controller. then use set_value to your input fields to retain the values after submit
CONTROLLER
public function index(){
if($this->input->post()){
//set rules for form validation
if($this->form_validation->run() !== FALSE){
//then update
}
}
//your views, data or any other things you do
}
VIEW
echo form_input('name', set_value('name'));

Answer 2

On click of the button you can bind the ajax call to submit the data to the update action of the controller and you can handle response to show relevant message on the same page.
Sample ajax call
$.ajax({
url:'settings/update',//controller action
type:'POST',
dataType:'JSON',
data:{'data':data,'id':id},//form data you need to upate with the id
success:function(response) {
//show success message here
},
error:function(response) {
//show error message here
}
});
Hope this helps.
