thanks

i think need use json.stringify(selecteddata) in order use on serverside.

jquery: 

var obj = { 'risk_cat': risk_cat, 'risk_type': risk_type }; selecteddata.push(obj);  $.post('serive.php', { dto: json.stringify(selecteddata) },  function(data){ /* handle response,  */ });

service.php:

header('content-type: application/json'); header('cache-control: no-cache, must-revalidate');  $foo = json_decode($_post['dto']);   $arr = array('a' => 1, 'b' => 2, 'c' => 3, 'd' => 4, 'e' => 5); //example data  echo json_encode($arr);

this should started. in ajax reponse, alert(data.a) alerting "1"
