I use the following the jquery statements to call my php controller function, it gets called but my result is not returned to my success function….

            $(document).ready(function() {
                getRecordspage();
            });

            function getRecordspage() {
                $.ajax({
                    type: "POST",
                    url:"http://localhost/codeigniter_cup_myth/index.php/adminController/mainAccount",
                    data: "{}",

                    global:false,
                    async: true,
                    dataType: "json",
                    success: function(result) {
                        alert(result);
                    }
                });
            }

            </tr>
            <tr> <td colspan="5"> </td></tr>
        </table>
    </body>
</html>

My controller method,

function mainAccount()
{
    $_SESSION['menu'] = 'finance';
    $data['account'] = $this->adminmodel->getaccountDetails();
    if(empty($data['account']))
    {
        $data['comment'] = 'No record found !';
    }
    $json = json_encode($data);
    return $json;
}

I get the alert(1); in my success function but my alert(result); show null. How do I fix this problem?

This was what I got when I gave print_r($data);:

Array ( [account] => Array ( [0] => Array ( [dAcc_id] => 1 [dAccountName] => Govt. College Of Technology [dAccountAcronym] => GCT [dFromDate] => 2010-04-02 [dToDate] => 2011-05-03 ) [1] => Array ( [dAcc_id] => 3 [dAccountName] => sample4 [dAccountAcronym] => smp_4 [dFromDate] => 2010-03-17 [dToDate] => 2011-03-03 ) [2] => Array ( [dAcc_id] => 4 [dAccountName] => sample3 [dAccountAcronym] => smp_3 [dFromDate] => 2010-03-16 [dToDate] => 2011-03-17 ) [3] => Array ( [dAcc_id] => 5 [dAccountName] => sample5 [dAccountAcronym] => smp_5 [dFromDate] => 2010-03-12 [dToDate] => 2011-03-03 ) [4] => Array ( [dAcc_id] => 6 [dAccountName] => sample2 [dAccountAcronym] => smp2 [dFromDate] => 2010-03-01 [dToDate] => 2011-03-16 ) [5] => Array ( [dAcc_id] => 7 [dAccountName] => sample1 [dAccountAcronym] => smp_1 [dFromDate] => 2010-03-11 [dToDate] => 2011-03-03 ) [6] => Array ( [dAcc_id] => 8 [dAccountName] => ss [dAccountAcronym] => ss [dFromDate] => 2010-04-04 [dToDate] => 2010-04-06 ) ) )

When I did print_r(json_encode($data['account']));, I got this:

[{"dAcc_id":"1","dAccountName":"Govt. College Of Technology","dAccountAcronym":"GCT","dFromDate":"2010-04-02","dToDate":"2011-05-03"},{"dAcc_id":"3","dAccountName":"sample4","dAccountAcronym":"smp_4","dFromDate":"2010-03-17","dToDate":"2011-03-03"},{"dAcc_id":"4","dAccountName":"sample3","dAccountAcronym":"smp_3","dFromDate":"2010-03-16","dToDate":"2011-03-17"},{"dAcc_id":"5","dAccountName":"sample5","dAccountAcronym":"smp_5","dFromDate":"2010-03-12","dToDate":"2011-03-03"},{"dAcc_id":"6","dAccountName":"sample2","dAccountAcronym":"smp2","dFromDate":"2010-03-01","dToDate":"2011-03-16"},{"dAcc_id":"7","dAccountName":"sample1","dAccountAcronym":"smp_1","dFromDate":"2010-03-11","dToDate":"2011-03-03"},{"dAcc_id":"8","dAccountName":"ss","dAccountAcronym":"ss","dFromDate":"2010-04-04","dToDate":"2010-04-06"}]

    Have you set the content type correct?

    header('Content-Type: application/json');

    With CodeIgniter, are you meant to return the JSON object or output it? If there’s no view associated with the method then nothing will be output. Try, just to see if it works:

    $_SESSION['menu'] = 'finance';
$data['account'] = $this->adminmodel->getaccountDetails();
if (empty($data['account'])) {
  $data['comment'] = 'No record found !';
}
header('Content-Type: application/json');
echo json_encode($data);
exit;

    Lastly, verify the URL you are going to and see if it returns something.

    Take a look at JSON Helper.
