save()

• Saves the current push notification request in the queue.

send()

• Sends all requests in the queue to the Firebase server

• Returns an array mapping each token to a boolean indicating whether the push was successful.

Setup

To send the push notification you will need your API (Server) Key which can be found under the Cloud messaging tab in your Firebase dashboard settings.

This can be set:

• while constructing a new PushNotification object
• by calling the method setApiKey
• within src/config.ini (see src/config.ini.sample)

Usage

Setting the data field implicitly

$push = new PushNotification('_YOUR_API_KEY');
$push->to('adsfasdf:adsfadsfadf')
     ->withTitle('hello')
     ->withMessage('there')
     ->withLink('/msgevents')
     ->withBadge(1)
     ->save()
     ->send();

Setting the data field explicitly

$push = new PushNotification();
$push->to('adsfasdf:adsfadsfadf')
     ->withTitle('hello')
     ->withMessage('there')
     ->withData(['link' => '/msgevents'])
     ->withBadge(1)
     ->save()
     ->setApiKey('_YOUR_API_KEY')
     ->send();

• Both requests above will yield the following body being sent to the FCM server.

{
    "notification": {
        "body":"there",
        "title":"hello",
        "sound":"default",
        "click_action":"FCM_PLUGIN_ACTIVITY",
        "icon":"fcm_push_icon",
        "badge":1
    },
    "data":{
        "body":"there",
        "title":"hello",
        "link":"/msgevents"
    },
    "to":"adsfasdf:adsfadsfadfadsasd"
}"

Without data

$push = new PushNotification('_YOUR_API_KEY');
$push->to('adsfasdf:adsfadsfadf')
     ->withTitle('hello')
     ->withMessage('there')
     ->save()
     ->send();

Sending to multiple recipients

$messages = [
    [
        "token" => 'abc:1234',
        "title" => "Hello",
        "body" => "there",
        "link" => "/msgevents",
        "badge" => 5
    ],
    [
        "token" => 'def:5678',
        "title" => "World",
        "body" => "where",
        "link" => "/messages"
    ],
];

// Create new push notification object
// API Key to be read from config.ini
$push = new PushNotification();

// Add all messages to the queue
foreach ($messages as $message) {
    extract($message);
    $push->to($token)
         ->withTitle($title)
         ->withMessage($body)
         ->withLink($link)
         ->save();
}

// Send off queue
$result = $push->send();

// var_dump($result);
// array(2) {
//   ["abc:1234"]=>
//   bool(true)
//   ["def:5678"]=>
//   bool(true)
// }
