Firebase how to send Topic Notification
Solution 1
I fixed by replacing
$fields = array
(
'registration_ids' => $registrationIds,
'notification' => $msg
);
To
$fields = array
(
'to' => '/topics/alerts',
'notification' => $msg
);
Solution 2
You can send the notifications without curl (which was not available on my server). I prepared a function which can send a notification to a specified topic:
sendNotification("New post!", "How to send a simple FCM notification in php", ["new_post_id" => "605"], "new_post", "YOUR_SERVER_KEY");
function sendNotification($title = "", $body = "", $customData = [], $topic = "", $serverKey = ""){
if($serverKey != ""){
ini_set("allow_url_fopen", "On");
$data =
[
"to" => '/topics/'.$topic,
"notification" => [
"body" => $body,
"title" => $title,
],
"data" => $customData
];
$options = array(
'http' => array(
'method' => 'POST',
'content' => json_encode( $data ),
'header'=> "Content-Type: application/json\r\n" .
"Accept: application/json\r\n" .
"Authorization:key=".$serverKey
)
);
$context = stream_context_create( $options );
$result = file_get_contents( "https://fcm.googleapis.com/fcm/send", false, $context );
return json_decode( $result );
}
return false;
}

i am work with google firebase many time and i suggest my simple code for send notification on topic.
public function test()
{
// Method - 1
// $fcmUrl = 'https://fcm.googleapis.com/v1/projects/myproject-b5ae1/messages:send HTTP/1.1';
// $notification = [
// "message" => [
// "topic" => "foo-bar",
// "notification" => [
// "body" : "This is a Firebase Cloud Messaging Topic Message!",
// "title" : "FCM Message",
// ]
// ]
// ];
// Method - 2
$fcmUrl = 'https://fcm.googleapis.com/fcm/send';
$notification = [
"to" => '/topics/cbtf',
"data" => [
"message" : "Messaging Topic Message!",
]
]
];
$headers = [
'Authorization: key=AIza...............klQ5SSgJc',
'Content-Type: application/json'
];
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$fcmUrl);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($notification));
$result = curl_exec($ch);
curl_close($ch);
return true;
}
Solution 4
You can send notification to any of a topic in firebase. And you can do it from any language it's just a http request but Always you have to maintain the JSON format so that you can catch notification from your android part from
public void onMessageReceived(RemoteMessage remoteMessage) {
super.onMessageReceived(remoteMessage);
Timber.d("Data Payload: " + remoteMessage.getData());
}
So You need to send below JSON format
{
"to": "\/topics\/general",
"data": {
"data": {
"title": "Database Notification",
"message": "New Data Added"
}
}
}
So that you can get this data set from remoteMessage.getData()
Solution 5
With particular Topic
<?php
print "testing";
function sendPushnotification($data = array()) {
$apiKey = '';
$fields = array('to' => '/topics/EWAP' , 'notification' => $data);
$headers = array('Authorization: key=' .$apiKey, 'Content-Type: application/json', 'priority' => 10);
$url = 'https://fcm.googleapis.com/fcm/send';
// var_dump($fields);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));
$result = curl_exec($ch);
curl_close($ch);
return json_encode($result, true);
}
$data = array(
'title' => 'Today topic',
'body' => 'done buddy'
);
var_dump(sendPushnotification($data));
?>

DIGITAL JEDI almost 2 years
I am using below script to send notification to particular users:
<?php // API access key from Google API's Console define( 'API_ACCESS_KEY', 'My_API_KEY' ); $registrationIds = array( TOKENS ); // prep the bundle $msg = array ( 'body' => "abc", 'title' => "Hello from Api", 'vibrate' => 1, 'sound' => 1, ); $fields = array ( 'registration_ids' => $registrationIds, 'notification' => $msg ); $headers = array ( 'Authorization: key=' . API_ACCESS_KEY, 'Content-Type: application/json' ); $ch = curl_init(); curl_setopt( $ch,CURLOPT_URL, 'https://fcm.googleapis.com/fcm/send' ); curl_setopt( $ch,CURLOPT_POST, true ); curl_setopt( $ch,CURLOPT_HTTPHEADER, $headers ); curl_setopt( $ch,CURLOPT_RETURNTRANSFER, true ); curl_setopt( $ch,CURLOPT_SSL_VERIFYPEER, false ); curl_setopt( $ch,CURLOPT_POSTFIELDS, json_encode( $fields ) ); $result = curl_exec($ch ); curl_close( $ch ); echo $result; ?>
Script is working fine but how can i send notification to all user who installed my app. I created a topic in my app (alerts), and i can send notification to all users via firebase console. Can anyone guide me to update above script for topic.
