android - How to send POST request to local server PHP script using Volley? -

i trying post value script running on local server. code given below :

 final string data = "poet=nazmul";         //toast.maketext(getapplicationcontext(), "ok", toast.length_long).show();         stringrequest request = new stringrequest(request.method.post, "http://192.168.1.112:8080/api/post.php?" + data, new response.listener<string>() {             @override             public void onresponse(string response) {                 toast.maketext(getapplicationcontext(), response, toast.length_long).show();             }         }, new response.errorlistener() {             @override             public void onerrorresponse(volleyerror volleyerror) {                 toast.maketext(getapplicationcontext(), volleyerror.tostring(), toast.length_long).show();             }         });         appcontroller.getinstance().addtorequestqueue(request); 

but local server not respond. php code is:

<?php  $poet = $_post['poet'];   echo json_encode(array('poet'=>$poet)); ?> 

when open url directly in web browser, error:

notice: undefined index: poet in c:\xampp\htdocs\api\post.php on line 2 {"poet":null}

how can solve problem?

you're doing request because of concatenation of ? , + data. if change server script $_post $_get , change request.method.post request.method.get work.
