Sending push notification to all users in query

Sending push notification to all users in query

This might help you Your problem is that a PFPush can't take any query, it needs a PFInstallation query. When you store your PFInstallation for each user, you could add a field that points to the current user, something like:
code :
PFInstallation *currentInstallation = [PFInstallation currentInstallation];
currentInstallation[@"user"] = [PFUser currentUser];
[currentInstallation saveInBackground];
PFQuery *installationQuery = [PFInstallation query];
PFUser *current = [PFUser currentUser];
[installationQuery whereKey:@"user" notEqualTo:current];
PFPush *push = [[PFPush alloc] init];
[push setQuery:installationQuery]; // <<< Notice query change here
[push setMessage:message];
[push sendPushInBackground];

it helps some times When a push URI is returned by MPNS it identifies a unique "app in device", i.e., every app installed in a device that requests for push notifications is given a different URI.
Now, I'm not responsible for the WP7 app, just the web servive part, but I think the app must revalidate the URI every time it launches. In that case, You should update the URI you stored previously and that's why You should store the device id, so You can track and update the previous channel.

I wish this helpful for you The format you are using can only be used for sending a single notification at a time. In order to send the notification to multiple registration IDs, you have to send a JSON request of the form :
code :
{ "collapse_key": "something",
  "time_to_live": 108,
  "delay_while_idle": true,
  "data": {
    "message": "some message"
  "registration_ids":["4", "8", "15", "16", "23", "42"]

will help you Parse has different possibilities depending on which kind of account you have. I assume you have the free one so you CANNOT send push notifications to specific or multiple users with this kind of account. BUT you can send them through the website controller to just iOS or Android users which is the only option you have with the free account.
I actually encourage you to use channels to do so. I assume you already have the correct initializations as explained in the parse website (https://parse.com/docs/android_guide)
code :
// Create our Installation query
ParseQuery pushQuery = ParseInstallation.getQuery();
pushQuery.whereEqualTo("channels", "Giants"); // Set the channel
pushQuery.whereEqualTo("scores", true);

// Send push notification to query
ParsePush push = new ParsePush();
push.setMessage("Giants scored against the A's! It's now 2-2.");

help you fix your problem It would be better to collect all the FCM tokens and use registration_ids to make sure you only send one HTTP request to the FCM server. You can find the full FCM HTTP protocol here.
code :

$connect = mysqli_connect("localhost", "***", "***", "***");

$message = $_POST["message"];
$title = $_POST["title"];
$path = "https://fcm.googleapis.com/fcm/send";
$server_key = "***";
$sql = "SELECT fcm_token FROM User";
$result = mysqli_query($connect, $sql);

$tokens = array();
while($row = mysqli_fetch_assoc($result)) {
    $tokens[] = $row["fcm_token"];

$headers = array("Authorization:key=" . $server_key, "Content-Type:application/json");
$fields = array(
    "registration_ids" => $tokens,
    "notification" => array("title" => $title, "body" => $message)
$payload = json_encode($fields);

$curl_session = curl_init();
curl_setopt($curl_session, CURLOPT_URL, $path);
curl_setopt($curl_session, CURLOPT_POST, true);
curl_setopt($curl_session, CURLOPT_HTTPHEADER, $headers);
curl_setopt($curl_session, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl_session, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl_session, CURLOPT_IPRESOLVE, CURL_IFRESOLVE_V4);
curl_setopt($curl_session, CURLOPT_POSTFIELDS, $payload);

$curl_result = curl_exec($curl_session);


$response = array();
$response["success"] = true;

echo json_encode($response);

this one helps. First of all you should read the documentation as Aditay Said.
GCM communicates with your app using your pacakge signature and app id which you provided in googole developer console.
