javascript - AJAX POST REQUEST -

-

i'm trying save data database javascript using ajax. part of code create request , send json formatted data save/save1.php:

urlpath = "save/save1.php"; var request = new xmlhttprequest(); request.addeventlistener('load',function() {                 console.log(this.responsetext);   });   idgame = "1";  data = json.stringify({'iduser': iduser, 'idgame': idgame, 'score': score});    request.addeventlistener('error', function () {                     document.write('there error ajax request!');  }); request.addeventlistener('load', this.onsuccess);  request.onreadystatechange = function(){     if(request.readystate == 4){             alert(request.responsetext);         }   };  request.open("post", urlpath); request.setrequestheader('content-type','application/json'); request.send(data);

and save1.php file:

<?php  include '../database_connection.php'; var_dump($_post);die(); //this debuging , prints array empty  if (isset($_post['iduser']) && isset($_post['idgame']) && isset($_post['score'])) {        $rez = $_post['score'];       $idgame = $_post['idgame'];       $iduser = $_post['iduser'];       $query = 'insert scores (iduser, idgame, score) values          ('.$iduser.','.$idgame.','.$rez.');';       $sucess = mysql_query($query);      if($sucess)     {           echo 'yes';      }    else            {        sendjsonresponse(array(              'error' => "not saved"));      } }   else {      sendjsonresponse(array(          'error' => "not set"));    }; function sendjsonresponse($data) {     header('content-type: application/json');     die(json_encode($data)); }

what doing wrong? :(

edit: solved it. found explanation:

i noticed setting contenttype well... work won't able use $_post var. instead you'll need grab data file_get_contents("php://input") "should" give raw json string. there should able use php's json_decode turn true php object.

so added save1.php document:

$data = json_decode(file_get_contents('php://input'), true); if (isset($data['iduser']) && isset($data['idgame']) && isset($data['score']))  {      $rez = $data['score']; //and on...
