javascript - Issue with sending data to PHP from jQuery .ajax call -

alright using yii , need pass data controller method called events , jquery ajax call looks this

var objecttosend = { "categories" : [selectedoption],"datefrom" : month + "" + year , "dateto" : month + "" + year};                    $.ajax({                         url: '<?php echo yii::app()->createurl('calendar/events'); ?>',                         type: "post",                         data: objecttosend,                          success: function(data) {                             console.log(data);                         },                         error: function() {                             console.log('failed');                         }                      }); 

so send data calendar/events , "catched" events method, db fetching , bring data jquery uppo success. problem error logged , message (failed) console when doing it. empty string controllers method, weird. testing out simple code in it, looks this

public function actionevents()     {          $data = json_decode(yii::app()->request->getpost('data'),true); // assoc array returned if second param true          echo json_encode($data);             yii::app()->end();     } 

i guessing problem lies in data object sent method without data={ json data here }, { json data here } without "data=" part. think? there way can "prefix" data object send php file "data="somehow ? appreciate help

jquery api docs $.ajax's data param "is converted query string". result, json_decodeing useless. if want send json data, you'll need json.stringify objecttosend first. if this, should set appropriate content-type header.

apparently yii won't decode json post body according pr 2059 can use either php's json_decode or yii's version , post body yii::app()->request->getrawbody().

my guess don't want json_decode data , use post variables directly:

yii::app()->request->getpost('categories');
