json - Throwing out same response on login check PHP AND SWIFT -

i trying try , learn swift want backend server php , need convert php json app

now want put email , password in fields on app , send post request php server side , php validates details , sends response let me decide response.

i have managed post server side success think when response in xcode gives same output weather details correct or in-correct,i have looked every , followed tutorials keep getting same problem i'm guessing way check details in php file error , not success.

could help?

login.php

$email = addslashes(strip_tags($_post['email'])); $password = addslashes(strip_tags($_post['password'])); $password = md5($password); $returnvalue = array();  $sql = "select email, user_password `accounts` `email` = '$email' , user_password = '$password' limit 1"; $fetchuser = mysqli_query($db_connect, $sql); $row = mysqli_num_rows($fetchuser);  if($row = mysqli_num_rows($fetchuser) == 0){   $returnvalue["status"] = "error";   $returnvalue["message"] = "account not found";   echo json_encode($returnvalue); } else {   $returnvalue["status"] = "success";   $returnvalue["message"] = "account found";   echo json_encode($returnvalue); } 

swift code

    let useremail = useremailtextfield.text;     let userpassword = userpasswordtextfield.text;      if(useremail!.isempty || userpassword!.isempty)  { return; }      //send server     let request = nsmutableurlrequest(url: nsurl(string: "http://chaozsounds.com/chaozsounds/new-chaozsounds/teamchaozapp/register.php")!)     request.httpmethod = "post"     let poststring = "email=\(useremail)&password=\(userpassword)"     request.httpbody = poststring.datausingencoding(nsutf8stringencoding)     let task = nsurlsession.sharedsession().datataskwithrequest(request) { data, response, error in         guard error == nil && data != nil else {                                                          // check fundamental networking error             print("error=\(error)")             return         }          if let httpstatus = response as? nshttpurlresponse httpstatus.statuscode != 200 {           // check http errors             print("statuscode should 200, \(httpstatus.statuscode)")             print("response = \(response!)")         }          let returnvalue = nsstring(data: data!, encoding: nsutf8stringencoding)         print("returnvalue = \(returnvalue!)")         if(returnvalue == "success") {              // login successful             nsuserdefaults.standarduserdefaults().setbool(true, forkey:"isuserloggedin");             nsuserdefaults.standarduserdefaults().synchronize();             self.dismissviewcontrolleranimated(true, completion: nil);         }     }     task.resume() 

ok had work around , managed after put code below

// send post request  let request = nsmutableurlrequest(url: nsurl(string: "urllinkhere")!);     request.httpmethod = "post";     let poststring = "email=\(useremail!)&password=\(userpassword!)";     request.httpbody = poststring.datausingencoding(nsutf8stringencoding);      // success or error  let task = nsurlsession.sharedsession().datataskwithrequest(request) { data, response, error in         if error != nil {             print("no data found: \(error)")             return         }          if let httpstatus = response as? nshttpurlresponse httpstatus.statuscode != 200 {           // check http errors             print("statuscode should 200, \(httpstatus.statuscode)")             print("response = \(response!)")         }          // this, on other hand, can quite fail if there's server error,         // want wrap in `do`-`try`-`catch`:          {             let json =  try nsjsonserialization.jsonobjectwithdata(data!, options: .mutablecontainers) as? nsdictionary             if let parsejson = json {                 let returnvalue = parsejson["status"] as? string;                  print("returnvalue = \(returnvalue!)")                  if(returnvalue == "success") {                      // success                     nsuserdefaults.standarduserdefaults().setbool(true,forkey:"isuserloggedin");                     nsuserdefaults.standarduserdefaults().synchronize();                      self.dismissviewcontrolleranimated(true, completion: nil);                  }               }         } catch {             print(error)         }     }      task.resume()
