php - Status 200 = HttpPut works? -

i'm trying modify value of database (mysql). issue i'm using httput on android application , slim framework micro framework of php xampp managing database.

the problem it's doesn't modify database gives me status 200 when use response.getstatusline().getstatuscode().

and if didn't understood it, when receive status 200 it's because request had been succesful. can see here: status 200 ok

the request has succeeded.

am missing something? did understand wrong? why database doesn't change?

p.s. if need provide code, let me know in comment.

edit: here it's put method in php script.

$app->put("/cars/",function() use($app) {     $name = $app->request->put("name");     $description = $app->request->put("description");     $idcar = $app->request->put("idcar");      try{         $connection = getconnection();         $dbh = $connection->prepare("update cars set name = ?, description = ? idcar = ?");         $dbh->bindparam(1,$name);         $dbh->bindparam(2,$description);         $dbh->bindparam(3,$idcar);          $dbh->execute();         $connection = null;          header("http/1.1 200");         header("content-type:application/json; charset=utf-8");         echo json_encode(array('status' => true),json_unescaped_unicode );      }catch(pdoexception $e)     {         echo "error: " . $e->getmessage();     } }); 

edit 2: here it's code in use httpput.

class editcar extends asynctask<void, integer, void> {      private car editcar;      editcar(car editcar) {         this.editcar = editcar;     }      protected void onpreexecute() {     }      protected void doinbackground(void... params) {          try {              string url = "http://ip of computer/project/cars/";              httpclient httpclient = new defaulthttpclient();             httpput method = new httpput(url);              list<namevaluepair> namevaluepairlist = new arraylist<namevaluepair>();              namevaluepairlist.add(new basicnamevaluepair("name", editcar.getname()));             namevaluepairlist.add(new basicnamevaluepair("description", editcar.getdescription()));             namevaluepairlist.add(new basicnamevaluepair("idcar", integer.tostring(editcar.getidcar())));              method.setentity(new urlencodedformentity(namevaluepairlist));             httpresponse response = httpclient.execute(method);          } catch (exception ex) {             log.e("error", ex.tostring());         }          return null;     }      protected void onprogressupdate() {     }      protected void onpostexecute() {     } } 

the 200 status says nothing update.

• do choose right database connection?
• your query looks normal, can't see parameter values. sure contains right values?
• you can specify data type bindparam method
• you 'update', lastinsertid 'insert'

but, can this:

print_r([$name,$description,$idcar]); // temporaly line debugging!  $dbh = $connection->prepare("update cars set name = ?, description = ? idcar = ?"); $dbh->execute([$name,$description,$idcar]); 

if use < php 5.4: [] must array()
