My controller method,
function mainAccount()
{
$_SESSION['menu'] = 'finance';
$data['account'] = $this->adminmodel->getaccountDetails();
if(empty($data['account']))
{
$data['ment'] = '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:

The result body can be
null
and still be a valid result if the header is200 OK
. Have you checked your URL actually returns something? – Pekka Commented Apr 6, 2010 at 10:15 - @pekka i inspected through firebug my response tab had nothing.... – udaya Commented Apr 6, 2010 at 10:18

@pekka my post had this
JSON Source {}
– udaya Commented Apr 6, 2010 at 10:19 -
@udaya then the response is empty, and the
null
appears correctly - strange because in your code, that can't really happen. – Pekka Commented Apr 6, 2010 at 10:20 - @pekka any suggesstion how it can be done? – udaya Commented Apr 6, 2010 at 10:24

Reset to default 2Have 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'])) {
$data['ment'] = 'No record found !';
}
header('Content-Type: application/json');
echo json_encode($data);
exit;
Lastly, verify the URL you are going to and see if it returns something.
Take a look at JSON Helper.
The most mon reason this happens is if you are a non-secure page trying to municate via ajax with a secure page, or vise versa (i.e. http ajaxing https)
