Specific php and swift code for image uploading to sftp -

php script , xcode shows here

****** response data =
notice: undefined index: userid in /home/raimonds/script.php on line 36
{"message":"first name field empty","status":"error","userid":null}

so here php code :

<?php if(!empty($_post["firstname"])){      $firstname = isset($_post["firstname"]) ? $_post["firstname"] : "";     $lastname = isset($_post["lastname"]) ? $_post["lastname"] : "";     $userid = isset($_post["userid"]) ? $_post["userid"] : "";     $target_dir = "uploads/";      if(!file_exists($target_dir))     {     mkdir($target_dir, 0777, true);     }      $target_dir = $target_dir . "/" . basename($_files["file"]["name"]);      if (move_uploaded_file($_files["file"]["tmp_name"], $target_dir)) {         echo json_encode([         "message" => "the file ". basename( $_files["file"]["name"]). " has been uploaded.",         "status" => "ok",         "userid" => $_post["userid"]         ]);      } else {         echo json_encode([         "message" => "sorry, there error uploading file.",         "status" => "error",         "userid" => $_post["userid"]         ]);     }  }else{          echo json_encode([         "message" => "first name field empty",         "status" => "error",         "userid" => $_post["userid"]         ]);  }  ?>

you have problem in swift code, because don't send post data php

try how send swift post request: http://ios-blog.co.uk/tutorials/swift-how-to-send-a-post-request-to-a-php-script/

you need that:

var url: nsurl = nsurl(string: "http://raimonds.gtd.lv/script.php")! var request:nsmutableurlrequest = nsmutableurlrequest(url:url) request.httpmethod = "post" var bodydata = "firstname=firstname&lastname=lastname&userid=9" request.httpbody = bodydata.datausingencoding(nsutf8stringencoding); nsurlconnection.sendasynchronousrequest(request, queue: nsoperationqueue.mainqueue()) {     (response, data, error) in     println(response)  }
