There is a php script on the server
<?php $response = array(); if (isset($_POST['NameFile']) && isset($_POST['PathFile']) && isset($_POST['Tag']) && isset($_POST['Rating']) && isset($_POST['Author']) && isset($_POST['ArrayEditor']) && isset($_POST['ArrayAnswer'])) { $NameFile = $_POST['NameFile']; $PathFile = $_POST['PathFile']; $Tag = $_POST['Tag']; $Rating = $_POST['Rating']; $Author = $_POST['Author']; $ArrayEditor = $_POST['ArrayEditor']; $ArrayAnswer = $_POST['ArrayAnswer']; require 'db_connect.php'; $db = new DB_CONNECT(); $result = mysql_query("INSERT INTO file(NameFile, PathFile, Tag, Rating, Author, ArrayEditor, ArrayAnswer) VALUES('$NameFile', '$PathFile', '$Tag', '$Rating', '$Author', '$ArrayEditor', '$ArrayAnswer')"); if ($result) { $response["success"] = 1; $response["message"] = "Product successfully created."; echo json_encode($response); } else { $response["success"] = 0; $response["message"] = "Oops! An error occurred."; echo json_encode($response); } } else { $response["success"] = 0; $response["message"] = "Required field(s) is missing"; echo json_encode($response); } ?> If you just go now to the address http://educt.landmarkstd.ru/create_file.php Then it will output an array with an error.
Now I'm trying to create a new entry in android
List<NameValuePair> params = new ArrayList<NameValuePair>(); params.add(new BasicNameValuePair("NameFile", itemList.nameList)); params.add(new BasicNameValuePair("PathFile", "serverFalse")); params.add(new BasicNameValuePair("Tag", itemList.Tag)); params.add(new BasicNameValuePair("Rating", "5.0")); params.add(new BasicNameValuePair("Author", "Fasd")); params.add(new BasicNameValuePair("ArrayEditor", "Test")); params.add(new BasicNameValuePair("ArrayAnswer", "2*2:2*3:2*4")); final JSONObject json = jsonParser.makeHttpRequest(url_create_product, "POST", params); Log.d("Create Response", json.toString()); try { int success = json.getInt(TAG_SUCCESS); if (success == 1) { Log.d("myLog", "Файл успешно добавлен"); } } catch (JSONException e) { Log.d("myLog", "Неудалось"); e.printStackTrace(); } return null; And this line is Log.d("Create Response", json.toString()); Returns null, although the record is added to the database itself.
And this is the error log:
