php - Array params in Volley StringRequest -

-

i have trouble sending stringrequest. 1 of params must array

here request:

public void sendtowebservice(final string login, final string mdp, final reprise rep){     string url = myapplication.geturlws();     final requestqueue request = requestqueuesingleton.getinstance().getrequestqueue();     stringrequest sr = new stringrequest(request.method.post, url, new response.listener<string>() {         @override         public void onresponse(string response) {             rep.setstatus(1);             reprisedao db = new reprisedao(context);             db.addvehicule(rep);         }     }, new response.errorlistener() {         @override         public void onerrorresponse(volleyerror error) {         }     }){         @override         protected map<string,string> getparams(){              map<string, string> params = new hashmap<string, string>();             params.put("login", login);             params.put("password", mdp);               ...               jsonarray jarray = new jsonarray();             (equipement equ : rep.getequipements()) {                 jarray.put(equ.getid());             }             string data= jarray.tostring();             params.put("caroptions", data);              params = checkparams(params); //this put empty string if param null             return params;         }     };      request.add(sr); }

this php code of webservice. show interesting part:

foreach($_post['caroptions'] $v) {     $query_options='insert cars_options_car (carid, optionid) values (' . (int)$lastid . ',' . (int)$v . ')';     $request_options=mysql_request($query_options);  }

as can see, webservice expect receive array in "caroptions" param. after little research, i've tried make jsonarray , convert string. request received webservice seems array not converted.

should use other kind of request ? i've tried jsonrequest seems webservice doesn't accept jsonrequest.
