Google Cloud Messaging- Sending Push Message To Android Using PHP
Question
I am working on an android project where I need to push messages using GCM. I wanna send the notification using only PHP and not HTML. How do I achieve this? The way I tried was just putting the gcm_regid and message as parameters to $gcm->send_notification($registration_ids,$msg) but I keep getting an error saying:- Field "data" must be a JSON array: ["You Have A Notification!"]
Where "You Have A Notification!" is my msg!! Please help!! Thanks!
Code for send_notification is
public function send_notification($registatoin_ids, $message) {
include_once './config.php';
// Set POST variables
$url = 'https://android.googleapis.com/gcm/send';
$fields = array(
'registration_ids' => $registatoin_ids,
'data' => $message,
);
$headers = array(
'Authorization: key=' . GOOGLE_API_KEY,
'Content-Type: application/json'
);
// 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;
}
}
This is the index.php used for sending the message using the button's on-click. I need to however do this automatically in the background without any button press and want to implement it in PHP.

Maybe this will work:
$fields = array(
'registration_ids' => $registatoin_ids,
'data' => array("message" => $message),
);

You will need to embed the registration_id too in array.
$fields = array(
'registration_ids' => array($registatoin_ids),
'data' => array("message" => $message),
);

$fields[] = array(
'registration_ids' =>$registatoin_ids,
'data' =>$message
);
use square braces with $fields this will make it a json array
