CodeIgniter put 0 instead of string values to a database - database

Question

I'm trying to build a small blog with CodeIgniter, and for some reason I put form database entries 0 instead of strings. I tried to put it through the controller manually and it works. What's the problem in a form?
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class site_model extends CI_Model {
var $title = '';
var $content = '';
var $date = '';
function __construct()
{
// Call the Model constructor
parent::__construct();
}
function get_records()
{
$query = $this->db->get('posts');
return $query->result();
}
function add_records($data) {
$this->db->insert('posts', $data);
return;
}
function updata_records($data) {
$this->db->where('postID', $id);
$this->db->updata('posts', $data);
}
function delede_roe() {
$this->db->where('postID', $this->uri->segment(3));
$this->db->delete('posts');
}
}
/* End of file welcome.php */
/* Location: ./application/controllers/welcome.php */
the form page:
<div class="grid_11">
<h2>About</h2>
<?php echo form_open('site/creata'); ?>
<label for="title"> title </label>
<input type="text" name="title" id="title">
<label for="content"> content </label>
<input type="text" name="content" id="content">
<br>
<input type="submit" value="send">
<?php echo form_close(); ?>
</div>
the controler:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class site extends CI_Controller {
/**
* Index Page for this controller.
*
* Maps to the following URL
* http://example.com/index.php/welcome
* - or -
* http://example.com/index.php/welcome/index
* - or -
* Since this controller is set as the default controller in
* config/routes.php, it's displayed at http://example.com/
*
* So any other public methods not prefixed with an underscore will
* map to /index.php/welcome/<method_name>
* #see http://codeigniter.com/user_guide/general/urls.html
*/
public function index()
{
$this->load->view('home');
}
function add_post() {
$this->load->view('add_post');
}
function creata() {
$data = array (
'title' => $this->input->post('title'),
'post' => $this->input->post('content')
);
$this->load->model('site_model');
$this->site_model->add_records($data);
}
}

Answer 1

Your controller function should look something like this:
function creata() {
if( $this->input->post(null) ){ //enter if the form is submitted
$data = $this->input->post(null, true); // get all the data of the post
print_r( $data );die; // see the post data
$this->load->model('site_model');
$this->site_model->add_records($data);
$this->session->set_flashdata('msg', 'A msg to show to the user about the insertion');
redirect('site/creata', 'refresh');
}else{ //load the form
$this->load->view('home');
}
}
You form looks okay to me tho. You model may contain one extra line to view the query.
function add_records($data) {
$this->db->insert('posts', $data);
$this->db->last_query(); die; //check the query it's executing.
return;
}
