I need to send GCM notifications to multiple devices. Here i made PHP code to get the array of Registration ID from MySql and tried to send notification to multiple devices but there is some problem here.
My PHP Code:
<?php
if($_SERVER['REQUEST_METHOD']=='GET'){
$tags = $_GET['tags'];
$api_key = 'My OWN API KEY';
//Getting registration token we have to make it as array
//Getting the message
$message = Testing GCM';
$title= 'Cuboid';
$vibrate= '1';
$sound= '1';
require_once('dbConnect.php');
$user_ids = array();
foreach ($_REQUEST['tags'] as $key => $val) {
$user_ids[$key] = filter_var($val, FILTER_SANITIZE_STRING);
}
$tagss = "'" . implode("','", $user_ids) . "'";
$sql = "SELECT user_tags.user_id AS userID , gcm_token.regtoken AS regToken
FROM user_tags,gcm_token
WHERE tags IN ({$tagss}) AND user_tags.user_id=gcm_token.user_id";
$r = mysqli_query($con,$sql);
//creating a blank array
$result = array();
$reg_token = array();
//looping through all the records fetched
while ($row = mysqli_fetch_array($r)) {
$result['regToken'][] = $row['regToken'];
}
//Displaying the array in json format
echo json_encode(array('result'=>$result));
$reg_token = (json_encode(array('result'=>$result)));
//$reg_token = array('result'=>$result);
$msg = array
(
'message' => $message,
'title' => $title,
'subtitle' => 'Android Push Notification using GCM Demo',
'tickerText' => 'Ticker text here...Ticker text here...Ticker text here',
'vibrate' => $vibrate,
'sound' => $sound,
'largeIcon' => 'large_icon',
'smallIcon' => 'small_icon'
);
//Creating a new array fileds and adding the msg array and registration token array here
$fields = array
(
'registration_ids' => $reg_token,
'data' => $msg
);
//Adding the api key in one more array header
$headers = array
(
'Authorization: key=' . $api_key,
'Content-Type: application/json'
);
//Using curl to perform http request
$ch = curl_init();
curl_setopt( $ch,CURLOPT_URL, 'https://android.googleapis.com/gcm/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 ) );
//Getting the result
$results = curl_exec($ch );
curl_close( $ch );
//Decoding json from results
$res = json_decode($results);
mysqli_close($con);
}
