如何在将数据发送到数据库时更改日期格式？

I am using jquery full calendar to show some booking details. I am inserting date into the database in ("yyyy-MM-dd") format.

But when i retrieve the title value from the calendar using var title=$("#calendar").fullCalendar('getView').title; it output as "June 2015". later i am using these two days for a comparison. Therefor i need to either send date into the database in "19 June 2015" format or convert title date value into "06 2015".

If anyone has a clear idea about this help me. Hope the problem is clear. I am using codeignier and i use the following cotroller method to send the data into the database.

function add_reservation() {
        $reservation_model = new Reservation_model();
        $reservation_service = new Reservation_service();

        $reservation_model->set_date_cal(trim($this->input->post('date', TRUE)));
       // $reservation_model->set_date(strtotime($this->input->post('date', TRUE)));
        $reservation_model->set_title(trim($this->input->post('selected_hall', TRUE)));
        $reservation_model->set_type(trim($this->input->post('selected_time', TRUE)));
        $reservation_model->set_description(trim($this->input->post('name', TRUE)));
        $reservation_model->set_advanced_payment_status(trim($this->input->post('optionsRadios', TRUE)));
        //$reservation_model->set_advanced_payment_status(trim($this->input->post('no', TRUE)));
        $reservation_model->set_paid_amount(trim($this->input->post('paid_amount', TRUE)));
        $reservation_model->set_fax(trim($this->input->post('fax', TRUE)));
        $reservation_model->set_telephone_number(trim($this->input->post('telephone', TRUE)));
        $reservation_model->set_address(trim($this->input->post('address', TRUE)));
        $reservation_model->set_menu_no(trim($this->input->post('selected_menu_number', TRUE)));
        $reservation_model->set_menu_price_per_plate(trim($this->input->post('menu_price', TRUE)));
        $reservation_model->set_is_deleted('0');

        $this->db->last_query();

        echo $reservation_service->add_reservation($reservation_model);


}

basically i want to change the format of the date which i am sending to the database as "19 June 2015"

Don't change the MySQL format. Change your html OR keep every thing the same way it is now and use javascript to convert it to mysql format.

var title=$("#calendar").fullCalendar('getView').title; // "June 2015"
var d = new Date(title);
var title = d.getFullYear() + "-" +( d.getMonth() + 1); // "2015-6"

Now, you can compare. Let me know, if you are looking for something else.

Considering your the date you have as 2015-06-19 and your DB Date as June 2015

<?php
$date = "2015-06-19";
$month = date("F", strtotime($date));
$year = date("Y", strtotime($date));
$MyDate = $month.' '.$year;
$MyDBDate = "June 2015";

if ($MyDate == $MyDBDate) 
{
    # Your Action Here
}

You can change the condition or dates according to your need.

Here's the EVAL Link for you

Update :

Updated with Javascript version to compare as per OP's Request

<script>
var MyDate = "<?php echo $MyDate?>";
var MyDBDate = "June 2015";
if (MyDate ==MyDBDate) 
{
    alert('Match');
} else {
    alert('Not a Match');
}
</script>

Format date

 $newDate = date('d F Y',strtotime($_POST['date']));

FROM Database SQL

DATE_FORMAT(DateValueDb,'%d %b %Y')
