how to determine the URL for ajax

Question

As stated in the title...I am having trouble determining whether I'm actually performing the post operation properly or if the operation is properly performed then why is the value empty since I checked the value before passing it in the post operation...here is my code:

script:

$.ajax({
    url: "<?php echo base_url();?>/Index/viewDayDocuments",
    type: 'post',
    data: {currentDay: 'currentDay', currentMonth: 'currentMonth', currentYear: 'currentYear'},
    success: function(result){
        $('.list').text('');
        $('.list').remove();
        $(".listIncoming").html("<p class = 'list'>This is the: "+ result +"</p>");
        $("#myform").show(500);
    }
 });

controller code which throws back a return value:

    $data['day'] = $_POST['currentDay'];
        $data['month'] =  $_POST['currentMonth'];
        $data['year'] =  $_POST['currentYear'];

        $date = $data['year']."-".$data['month']."-".$data['day'];

        $this->load->model('search_form');
        $output['details'] = $this->search_form->searchDateRetrievedIncoming($date);

        return $data;

Your ajax request needs a string echoed as a string.

  $data['day'] = $_POST['currentDay'];
    $data['month'] =  $_POST['currentMonth'];
    $data['year'] =  $_POST['currentYear'];

    $date = $data['year']."-".$data['month']."-".$data['day'];

    $this->load->model('search_form');
    $output['details'] = $this->search_form->searchDateRetrievedIncoming($date);

    echo json_encode($data);

An array cannot be echoed out correctly if it's not in a data format, such as JSON.

Now we, take the data in your javascript

$.ajax({
url: "<?php echo base_url();?>/Index/viewDayDocuments",
type: 'post',
data: {currentDay: 'currentDay', currentMonth: 'currentMonth', currentYear: 'currentYear'},
success: function(result){
    $('.list').text('');
    $('.list').remove();
    date = JSON.parse(result);
    $(".listIncoming").html("<p class = 'list'>This is the: "+ date.month +"/"+date.day+ "/"+date.year +"</p>");
    $("#myform").show(500);
  } 
 });

In this module, I transformed the STRING from your PHP file into a JSON object so it can be read properly.
