Ios And Android Push Notifications To Multiple Devices
I am really struggling with this. This piece of code wasn't created by me but I have changed it so it sort of works. My goal is for it to be able to send push notifications to all
Solution 1:
I figured this out a while ago and though I would share for anyone else that is struggling.
<?php
include 'conn.php';
if ( $_REQUEST['key'] == 'notification' ) {
$message = $_REQUEST['text'];
$text = mysql_real_escape_string( $_REQUEST['text'] );
$start = $_REQUEST['start'];
$end = $_REQUEST['end'];
$date = date( "Ymd", strtotime( $_REQUEST['date'] ) );
$callus = $_REQUEST['callus'];
$in = "INSERT INTO `notifications` (`date`, `start_time`, `end_time`, `text`, `call_us`) VALUES ('$date', '$start', '$end', '$text', '$callus');";
mysql_query($in);
include 'notifications.php';
}
else {
$message = mysql_real_escape_string( $_REQUEST['text'] );
$time = date( 'Y-m-d H:i:s' );
$in = "INSERT INTO `alerts` (`text`, `time`) VALUES ('$message', '$time');";
mysql_query( $in );
$sel="SELECT * FROM `users` GROUP by device_token";
$rs = mysql_query( $sel ) or die('');
if ( mysql_num_rows( $rs ) != 0 ) {
while( $row=mysql_fetch_array( $rs ) ) {
$regi = array();
$regi[] = $row['device_token'];
$dev = $row['device_token'];
if( strlen ( $dev ) > 65 ) {
$regis[] = $row['device_token'];
}
else if ( strlen ($dev) > 25 ) {
$ios[] = $dev;
}
}
}
$deviceToken=$_REQUEST['device'];
$json=json_decode($deviceToken);
//google Push notification
// API access key from Google API's Console
define( 'API_ACCESS_KEY', 'AIzaSyCMysH7TySEgdbvRoCLoZk8uFF1x_A3uxg' );
//build the message
$fields = array
(
'registration_ids' => $regis,
'data' => array( 'message'=> $message,'count'=>1 )
);
$headers = array
(
'Authorization: key=' . API_ACCESS_KEY,
'Content-Type: application/json'
);
$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 ) );
$result = curl_exec($ch );
curl_close( $ch );
//Apple Push notification
// Certificate password:
$passphrase = '123456789';
$ctx = stream_context_create();
stream_context_set_option($ctx, 'ssl', 'local_cert', 'ckStudioeast.pem');
stream_context_set_option($ctx, 'ssl', 'passphrase', $passphrase);
// Open a connection to the APNS server
$fp = stream_socket_client(
'ssl://gateway.push.apple.com:2195', $err,
$errstr, 60, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $ctx);
if (!$fp)
exit("Failed to connect: $err $errstr" . PHP_EOL);
// Create the payload body
$body['aps'] = array(
'alert' => $message,
'sound' => 'default',
'badge' => '1'
);
// Encode the payload as JSON
$payload = json_encode($body);
// Loop though device tokens
foreach($ios as $dev) {
if($dev!=''){
// Build the binary notification
$msg = chr(0) . pack('n', 32) . pack('H*', $dev) . pack('n', strlen($payload)) . $payload;
//Send it to the server
$result = fwrite($fp, $msg, strlen($msg));
}
}
if (!$result)
echo 'Message not delivered' . PHP_EOL;
// Close the connection to the server
fclose($fp);
include 'index.php';
}
?>
The problem seemed to be that the app was sending the database a development device token so I updated my didRegisterForRemoteNotificationsWithDeviceToken function in xcode to this:
- (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken{
#ifdef DEBUG
// Update the database with our development device token
NSLog(@"IN DEVELOPMENT MODE!!!!!!!");
#else
// Update the database with our production device token
NSString *token = [[deviceToken description] stringByTrimmingCharactersInSet: [NSCharacterSet characterSetWithCharactersInString:@"<>"]];
token = [token stringByReplacingOccurrencesOfString:@" " withString:@""];
NSLog(@"content---%@", token);
kSetValueForKey(@"device_token", token);
[self updateDeviceToken:token];
#endif
}
Also I found that if a user denies the request to allow push notifications that it send a device token of 0 to my database, which if used stops the notifications from being sent. So where I'm sorting my device tokens in my php file I added more logic to ignore all the tokens that where just 0.
I simply just checked that the length was more than 25 characters before I added it to my $ios array, where as before I wasn't
Old code:
if( strlen ( $dev ) > 65 ) {
$regis[] = $row['device_token'];
} else {
$ios[] = $dev;
}
New code:
if( strlen ( $dev ) > 65 ) {
$regis[] = $row['device_token'];
} else if ( strlen ($dev) > 25 ) {
$ios[] = $dev;
}
One of the main problems I found is if you send a device token to apples production push notification server that isn't a valid production device token, it just doesn't send the notification to any device. This is why I It wasn't working and I have added in the extra logic to my php code and Objective-c code to filter out all the invalid device tokens.
Hope this helps people.
Solution 2:
while ($row = mysql_fetch_array($result1)) //fetch datafrom loop
{
$dev = $row["device_token"]; // your devide token
if( strlen ( $dev ) > 65 ) { // for android
$regis[] = $row['device_token'];
}
else
{
$ios[] = $row['device_token']; // for ios
}
}
foreach($regis as $dev1) {
$id=$dev1;
$url = 'https://fcm.googleapis.com/fcm/send';
$fields = array (
'to' => $id,
'notification' => array (
"body" => $mess,
"icon" =>"icon",
"sound"=> ""
)
);
$fields = json_encode ( $fields );
$headers = array (
'Authorization: key=' . "---your key---",
'Content-Type: application/json'
);
$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_POSTFIELDS, $fields );
$result = curl_exec ( $ch );
}
foreach($ios as $dev) {
if($dev!='')
{
$deviceToken=$dev;
$passphrase = '';
// Put your alert message here:
$message = $mess;
$ctx = stream_context_create();
stream_context_set_option($ctx, 'ssl', 'local_cert', 'ck.pem');
stream_context_set_option($ctx, 'ssl', 'passphrase', $passphrase);
// Open a connection to the APNS server
$fp = stream_socket_client('ssl://gateway.push.apple.com:2195', $err, $errstr, 60, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $ctx);
// Create the payload body
$body['aps'] = array(
'alert' => array(
'body' => $message,
),
'badge' => +1,
'sound' => 'default',
'content-available' => '1',
);
$payload = json_encode($body);
$msg = chr(0) . pack('n', 32) . pack('H*', $deviceToken) . pack('n', strlen($payload)) . $payload;
$result = fwrite($fp, $msg, strlen($msg));
}
}
if (!$result)
{
?>
<script>
alert("Push notification is successfully sent");
</script>
<?php
}
else
{
?>
<script>
alert("Mesaage is successfully sent");
</script>
<?php
}
curl_close ( $ch );
fclose($fp);
}
