I've been dealing with this issue since 2 days. What I want to do is, I've to send multiple messages to registered GCM device. Till now I can send single message to device. Below is the code to send message.
send_message.php
<?php
if (isset($_REQUEST["regId"]) && isset($_REQUEST["message"])) {
$regId = $_REQUEST["regId"];
$message = $_REQUEST["message"];
include_once './GCM.php';
$gcm = new GCM();
$registatoin_ids = array($regId);
$message = array("price" => $message);
$result = $gcm->send_notification($registatoin_ids, $message);
echo $registatoin_ids; echo $message;
echo $result;
}
GCM.php
<?php
class GCM {
//put your code here
// constructor
function __construct() {
}
//Sending Push Notification
public function send_notification($registatoin_ids, $message) {
// include config
include_once './config.php';
// Set POST variables
$url = 'https://android.googleapis.com/gcm/send';
$fields = array(
'registration_ids' => $registatoin_ids,
'message' => $message,
);
$headers = array(
'Authorization: key=' . GOOGLE_API_KEY,
'Content-Type: application/json'
);
//print_r($headers); exit();
// Open connection
$ch = curl_init();
// Set the url, number of POST vars, POST data
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Disabling SSL Certificate support temporarly
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));
// Execute post
$result = curl_exec($ch);
if ($result === FALSE) {
die('Curl failed: ' . curl_error($ch));
}
// Close connection
curl_close($ch);
echo $result;
}
}
?>
Here message is being received on receiver side.. // code for this is in GCM.php
$fields = array(
'registration_ids' => $registatoin_ids,
'message' => $message,
);
But I want to send multiple messages in single notification. for that what I did...
send_message.php
<?php
if (isset($_REQUEST["regId"]) && isset($_REQUEST["message"]) && isset($_REQUEST["data"])) {
$regId = $_REQUEST["regId"];
$message = $_REQUEST["message"];
$data = $_REQUEST["data"]; //added third parameter
include_once './GCM.php';
$gcm = new GCM();
$registatoin_ids = array($regId);
$message = array("price" => $message);
$data = array("extra" => $data);
$result = $gcm->send_notification($registatoin_ids, $message, $data);
echo $registatoin_ids; echo $message; echo $data;
echo $result;
}
GCM.php
<?php
class GCM {
//put your code here
// constructor
function __construct() {
}
/**
* Sending Push Notification
*/
public function send_notification($registatoin_ids, $message, $data) {
// include config
include_once './config.php';
// Set POST variables
$url = 'https://android.googleapis.com/gcm/send';
$fields = array(
'registration_ids' => $registatoin_ids,
'message' => $message,
'data' => $data,
);
$headers = array(
'Authorization: key=' . GOOGLE_API_KEY,
'Content-Type: application/json'
);
//print_r($headers); exit();
// Open connection
$ch = curl_init();
// Set the url, number of POST vars, POST data
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Disabling SSL Certificate support temporarly
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));
// Execute post
$result = curl_exec($ch);
if ($result === FALSE) {
die('Curl failed: ' . curl_error($ch));
}
// Close connection
curl_close($ch);
echo $result;
}
}
?>
And in android I wrote the function to receive message like this...
@Override
protected void onMessage(Context context, Intent intent) {
Log.i(TAG, "Received message");
String message = intent.getStringExtra("price");
String newmessage = intent.getStringExtra("extra");
displayMessage(context, message + newmessage);
generateNotification(context, message + newmessage);
}
But I'm getting null result for "price" and getting result for "extra". How can I receive multiple message string in single notification?
