在php中将数据发送到FancyBox

Question

I need to pass a value to a modal window (fancybox). To do this I created the following code:

$.fancybox.open({
    type: 'iframe', // ajax but switched to iframe for testing
    href: '<?php echo base_url(); ?>index.php/aggiungiFarmaci_controller',
    maxWidth: 800,
    maxHeight: 600,
    fitToView: false,
    autoSize: true,
    closeClick: false,
    autoCenter: true,
    scrolling: 'no',
    padding: 0,
    ajax: {
        type: "POST",
        cache: false,
        data: $("#formCF").serialize(),
    },
    helpers: {
        overlay: {
            closeClick: false,
            css: {
                'background': 'rgba(150,144,146,.60)'
            }
        }
    }
});

The page I want to open and populate with the value passed by the caller of the modal window has the following code:

public function index() {
    $this->load->helper((array('form')));
    $this->load->library('form_validation');
    $data = array('aic' => $this->input->post('codiceFarmaco'));
    $this->load->view('aggiungiFarmaci_view',$data);
}

Unfortunately I can not pass the parameter I wanted (AIC Code) to the modal window that opens without showing it. How can I fix? I think the problem lies in the code that calls fancybox, but I do not know what else to try. Thank you so much for the help
