Date not been inserted to database in codeigniter - codeigniter

Question

I am trying to insert a date in to my database. But it does not get inserted only the data does.
I am using codeigniter date helper http://www.codeigniter.com/user_guide/helpers/date_helper.html and the nice_date function
Date helper autoloaded.
My add_calendar_data function for some reason just will not insert the $good_date to the date column.
Testing date by echo data below
$bad_date = '1'.'-'.$calendar_dates['month'].'-'.$calendar_dates['year'];
$good_date = nice_date($bad_date, 'Y-d-m');
echo $good_date;
And that displays 2016-01-01
Question Why does the $good_date not get inserted to the database? And how could I solve this problem?
Update:
For some reason even though I can get the year and month on the index function and echo it fine. Will not let me pass the year and month to another through to another function
Controller
<?php
class Calendar extends MX_Controller {
public function index($calendar_dates = null) {
$this->load->model('dashboard/model_calendar');
$bad_date = '1'.'-'.$calendar_dates['month'].'-'.$calendar_dates['year'];
$good_date = nice_date($bad_date, 'Y-d-m');
echo $good_date;
// And that displays 2016-01-01
if ($this->input->post('day')) {
$bad_date = $this->input->post('day').'-'.$calendar_dates['month'].'-'.$calendar_dates['year'];
$this->add_calendar_data($bad_date);
}
$data['calendar'] = $this->model_calendar->generate($calendar_dates['year'], $calendar_dates['month']);
$this->load->view('dashboard/calender_view', $data);
}
public function add_calendar_data($bad_date) {
$good_date = nice_date($bad_date, 'Y-d-m');

Answer 1

It seems like you are trying to work with a function variable which is null try
class Calendar extends MX_Controller {
public function index($calendar_dates = null) {
$this->load->library('session');
$this->load->model('dashboard/model_calendar');
$bad_date = '1'.'-'.$calendar_dates['month'].'-'.$calendar_dates['year'];
$good_date = nice_date($bad_date, 'Y-d-m');
echo $good_date;
$this->session->set_flashdata('good_date', $good_date); //Store the variable
// And that displays 2016-01-01
if ($this->input->post('day')) {
$bad_date = $this->input->post('day').'-'.$calendar_dates['month'].'-'.$calendar_dates['year'];
$this->add_calendar_data($bad_date);
}
$data['calendar'] = $this->model_calendar->generate($calendar_dates['year'], $calendar_dates['month']);
$this->load->view('dashboard/calender_view', $data);
}
public function add_calendar_data() {
$calendar_data = array(
'date'=> $this->session->flashdata('good_date'),
'data' => $this->input->post('data')
);
$this->db->insert($this->db->dbprefix . 'calendar', $calendar_data);
}
}

Answer 2

change your date type to TEXT in your table and try again.

Answer 3

Solved
After working on it for a few hours I had found out why it was not getting the uri segments correct.
When I checked fire bug the form script was not loading correct url. And was missing the uri segments.
I can now insert the correct date.
url: 'dashboard/calendar',
Now changed to
url: window.location,
Full script
<script type="text/javascript">
$(document).ready(function() {
$('.calendar .day').click(function() {
day_num = $(this).find('.day_num').html();
day_data = prompt('Enter Stuff', $(this).find('.content').html());
if (day_data != null) {
$.ajax({
url: window.location,
type: 'POST',
data: {
day: day_num,
data: day_data
},
success: function(msg) {
location.reload();
}
});
}
});
});
</script>
Controller
<?php
class Calendar extends MX_Controller {
public function __construct() {
parent::__construct();
}
public function index() {
$this->load->model('dashboard/model_calendar');
if ($this->input->post('day')) {
$calendar = array(
'date' =>$this->uri->segment(3) .'-'. $this->uri->segment(4) .'-'. $this->input->post('day'),
'data' => $this->input->post('data')
);
$this->db->insert('calendar', $calendar);
}
$data['calendar'] = $this->model_calendar->generate($this->uri->segment(3), $this->uri->segment(4));
$this->load->view('dashboard/calender_view', $data);
}
}
