Question

Been playing with this for too long now!

I’m using codeigniter.

I am trying to get some data back from an Ajax get request. Simply I want to check a MySQL DB to check if there is some data in there mathcing a given date. A simple true or false will be fine for the return.

Here is my request, followed by the PHP. The PHP does return the correct result into $data, but when it gets back to the Ajax request, the alert(data) is called and shows up as blank… nothing there.

Any ideas what I’m doing wrong?

Thanks

function get_appointment_data(request_date){

    $.ajax({
    url: 'http://localhost/doctor_today/booking/retrieve_cal_data',
    type: 'GET',
    data: request_date,
    success: function(data){
                alert(data);
    }
    });
}




function retrieve_cal_data() {

    $this->load->model('Booking_model');

    $date = $this->input->get('date');      
    $data = $this->Booking_model->get_calendar_data($date);

    return $data==null;
}

I am not familiar with codeigniter but you must output the result of the function. Instade of ‘return’ you must use ‘echo’ to return result to ajax request.
