Parsing JSON array to Server with Swift 3.0 - php

Question

I am trying to send a JSON array to the web server. I have looked at several examples online i.e. https://www.youtube.com/watch?v=aTj0ZLha1zE&t and Saving CoreData to a Web Server with Swift 3.0 that have demonstrated how to parse data but I am struggling to achieve this.
Below is my function which should send the data to the server:
func sendRecordToServer() -> [Record] {
let fetchRequest = NSFetchRequest<NSDictionary>(entityName:"Record")
fetchRequest.resultType = .dictionaryResultType
do {
let records = try context.fetch(fetchRequest)
if let jsonData = try? JSONSerialization.data(withJSONObject: records, options: []) {
// jsonData is a byte sequence, to view it you would need to convert to string
print(String(bytes: jsonData, encoding: String.Encoding.utf8))
let URL_SAVE_DATA = URL(string: "http://localhost/api/postdata.php")
let request = NSMutableURLRequest(url: URL_SAVE_DATA!)
request.httpMethod = "POST"
request.httpBody = jsonData
let task = URLSession.shared.dataTask(with: request as URLRequest){
data, response, error in
guard let data = data, error == nil else {
// check for fundamental networking error
print("error=\(String(describing: error?.localizedDescription))")
return
}
let responseString = String(data: data, encoding: .utf8)
print("responseString = \(String(describing: responseString))")
}
task.resume()
}
} catch {
print("Error fetching data from CoreData")
}
return records
}
After encoding the data to JSON, it prints out like this:
Optional([["record_id": 8EC9C1C9-7DD4-4343-B7CC-E4615FDDA150, "name": John ], ["record_id": 7EEA551D-9432-4737-99FB-6BFCF3A92D21, "name": Fred Smith]])
However as I try parsing it though to the server I get this and nothing get sent to the server:
responseString = Optional("")
Update:
Following up from the comment below here is what my posdata.php looks like:
<?php
//creating response array
$json = file_get_contents('php://input');
//echo $json shoulkd show the json string
$array = json_decode($json, true);
// var_dump($arr) should show the array structure
$response = array();
if($_SERVER['REQUEST_METHOD']=='POST'){
//getting values
$record_id = $_POST['record_id'];
$name = $_POST['name'];
//including the db operation file
require_once '../includes/DbOperation.php';
$db = new DbOperation();
//inserting values
if($db->createTeam($record_id, $name)){
$response['error']=false;
$response['message']='Record added successfully';
}else{
$response['error']=true;
$response['message']='Could not add record';
}
}else{
$response['error']=true;
$response['message']='You are not authorized';
}
echo json_encode($response);
DBOperation:
<?php
class DbOperation
{
private $conn;
//Constructor
function __construct()
{
require_once dirname(__FILE__) . '/Config.php';
require_once dirname(__FILE__) . '/DbConnect.php';
// opening db connection
$db = new DbConnect();
$this->conn = $db->connect();
}
//Function to create a new user
public function createTeam($record_id, $name)
{
$stmt = $this->conn->prepare("INSERT INTO record (record_id, name) values (?, ?)");
$stmt->bind_param("si", $record_id, $name);
$result = $stmt->execute();
$stmt->close();
if ($result) {
return true;
} else {
return false;
}
}
}
