I have two classes. One for Invitation and another for notification from which I am pushing a notification to a device.

I want to call notification class when the invitation is inserted in the database.

I have extended the Invitation class with notification class but it is not working I am getting an empty output.

If I run single invitation or single notification class both works fine.

Invitation class:

 <?php require 'database.php'; require 'notification.php'; class Invitation extends notification { private $sender_id,$date,$invitee_no,$status,$invitations,$user_name,$contact_id,$contact_name; private $notify; public function setNotification($message,$user_name) { $this->send($message, $user_name); // calling superclass method } function Invitation($sender_id,$date,$invitee_no,$status,$user_name,$contact_id,$contact_name) { $this->sender_id = $sender_id; $this->date= $date; $this->invitee_no = $invitee_no; $this->status = $status; $this->user_name = $user_name; $this->contact_id = $contact_id; $this->contact_name = $contact_name; // $this -> invitations = $invitations; } function sendInvite() { $database = new Database(ContactsConstants::DBHOST, ContactsConstants::DBUSER, ContactsConstants::DBPASS, ContactsConstants::DBNAME); $dbConnection = $database->getDB(); $stmt = $dbConnection->prepare("select * from Invitation where user_name =? and sender_id = ?"); $stmt->execute(array($this->user_name,$this->sender_id)); $rows = $stmt->rowCount(); if ($rows > 0) { $response = array("status" => -3, "message" => "Invitation exists.", "user_name" => $this->user_name); return $response; } $this->date = ""; $this->invitee_no = ""; $this->status = "0"; $this->contact_id = 0; $this->contact_name = ""; echo $this->user_name; echo $this->sender_id; $stmt = $dbConnection->prepare("insert into Invitation(sender_id,date,invitee_no,status,user_name,contact_id,contact_name) values(?,?,?,?,?,?,?)"); $stmt->execute(array($this->sender_id, $this->date, $this->invitee_no, $this->status, $this->user_name,$this->contact_id,$this->contact_name)); $rows = $stmt->rowCount(); $Id = $dbConnection->lastInsertId(); $stmt = $dbConnection->prepare("select * from Invitation where invitation_id=?"); $stmt->execute(array($Id)); $invitation = $stmt->fetch(PDO::FETCH_ASSOC); if ($rows < 1) { $response = array("status" => -1, "message" => "Failed to send Invitation., unknown reason"); return $response; } else { // $notify = new notification(); // $resp = $notify->send($message, $this->user_name); $response = array("status" => 1, "message" => "Invitation sent.", "Invitation:" => $invitation); return $response; } }

notification:

 <?php require 'database.php'; class notification { private $text,$user_name; public function __construct() { } public function send($text,$userName) { $database = new Database(ContactsConstants::DBHOST, ContactsConstants::DBUSER, ContactsConstants::DBPASS, ContactsConstants::DBNAME); $dbConnection = $database->getDB(); $stmt = $dbConnection->prepare("Select device_id from Users where user_name =?"); $stmt->execute(array($userName)); $result = $stmt->fetch(PDO::FETCH_ASSOC); $token = $result["device_id"]; // echo $token; // echo $text; // echo $userName; if(!empty($token)) { echo $token; $response = $this->sendPush($text, $token, "AIzaSyBGwwJaThyLm-PhvgcbdYurj-bYQQ7XmCc"); } } public function sendPush($text, $tokens, $apiKey) { $notification = array( "title" => "You got an invitation.", "text" => $text, "icon" => "ic_chat_bubble_white_48dp", 'vibrate' => 3, 'sound' => "default" ); $msg = array ( 'message' => $text, 'title' => 'You got an invitation.', 'tickerText' => 'New Message', 'largeIcon' => 'large_icon', 'smallIcon' => 'small_icon' ); $fields = array ( 'to' => $tokens, 'data' => $msg, 'notification' => $notification ); $headers = array ( 'Authorization: key=' . $apiKey, 'Content-Type: application/json' ); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, 'https://android.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); echo($result); return $result; curl_close($ch); } } ?>

sendInvite script:

 <?php error_reporting(E_ERROR | E_WARNING | E_PARSE | E_NOTICE); ini_set('display_errors', '1'); require 'Invitation.php'; require 'notification.php'; $jsonText = file_get_contents('php://input'); if(empty($jsonText)) { $response = array("status"=>-2,"message"=>"Empty request"); die(json_encode($response)); } $json = json_decode($jsonText); $sender_id = $json-> sender_id; $user_name = $json -> user_name; echo $sender_id; echo $user_name; $invitation = new Invitation($sender_id,"","","",$user_name,"",""); $response = $invitation->sendInvite(); $message = 'Hi,add me to your unique contact list and you never need to update any changes anymore!'; $invitation->setNotification($message,$user_name); echo(json_encode($response)); ?>

How to integrate this?

EDIT:

I changed require to require_once

updated code:

Invitation:

 <?php require_once 'database.php'; require_once 'notification.php'; class Invitation extends notification { private $sender_id,$date,$invitee_no,$status,$invitations,$user_name,$contact_id,$contact_name; private $notify; public function setNotify($message,$user_name) { $this->send($message, $user_name); // calling superclass method } function Invitation($sender_id,$date,$invitee_no,$status,$user_name,$contact_id,$contact_name) { $this->sender_id = $sender_id; $this->date= $date; $this->invitee_no = $invitee_no; $this->status = $status; $this->user_name = $user_name; $this->contact_id = $contact_id; $this->contact_name = $contact_name; // $this -> invitations = $invitations; } function sendInvite() { $database = new Database(ContactsConstants::DBHOST, ContactsConstants::DBUSER, ContactsConstants::DBPASS, ContactsConstants::DBNAME); $dbConnection = $database->getDB(); $stmt = $dbConnection->prepare("select * from Invitation where user_name =? and sender_id = ?"); $stmt->execute(array($this->user_name,$this->sender_id)); $rows = $stmt->rowCount(); if ($rows > 0) { $response = array("status" => -3, "message" => "Invitation exists.", "user_name" => $this->user_name); return $response; } $this->date = ""; $this->invitee_no = ""; $this->status = "0"; $this->contact_id = 0; $this->contact_name = ""; $stmt = $dbConnection->prepare("insert into Invitation(sender_id,date,invitee_no,status,user_name,contact_id,contact_name) values(?,?,?,?,?,?,?)"); $stmt->execute(array($this->sender_id, $this->date, $this->invitee_no, $this->status, $this->user_name,$this->contact_id,$this->contact_name)); $rows = $stmt->rowCount(); $Id = $dbConnection->lastInsertId(); $stmt = $dbConnection->prepare("select * from Invitation where invitation_id=?"); $stmt->execute(array($Id)); $invitation = $stmt->fetch(PDO::FETCH_ASSOC); if ($rows < 1) { $response = array("status" => -1, "message" => "Failed to send Invitation., unknown reason"); return $response; } else { // $notify = new notification(); // $resp = $notify->send($message, $this->user_name); $response = array("status" => 1, "message" => "Invitation sent.", "Invitation:" => $invitation); return $response; } }

notification:

require_once 'database.php'; class notification { private $text,$user_name; public function __construct() { } public function setNotification($text, $username) { $this->text = $text; $this->user_name = $username; } public function send($text, $username) { $database = new Database(ContactsConstants::DBHOST, ContactsConstants::DBUSER, ContactsConstants::DBPASS, ContactsConstants::DBNAME); $dbConnection = $database->getDB(); $stmt = $dbConnection->prepare("Select device_id from Users where user_name =?"); $stmt->execute(array($this->username)); $result = $stmt->fetch(PDO::FETCH_ASSOC); $token = $result["device_id"]; echo $token; echo $this->text; echo $this->username; if(!empty($token)) { echo $token; $response = $this->sendPush($this->text, $token, "AIzaSyBGwwJaThyLm-PhvgcbdYurj-bYQQ7XmCc"); } } public function sendPush($text, $tokens, $apiKey) { $notification = array( "title" => "You got an invitation.", "text" => $text, "icon" => "ic_chat_bubble_white_48dp", 'vibrate' => 3, 'sound' => "default" ); $msg = array ( 'message' => $text, 'title' => 'You got an invitation.', 'tickerText' => 'New Message', 'largeIcon' => 'large_icon', 'smallIcon' => 'small_icon' ); $fields = array ( 'to' => $tokens, 'data' => $msg, 'notification' => $notification ); $headers = array ( 'Authorization: key=' . $apiKey, 'Content-Type: application/json' ); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, 'https://android.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); echo($result); return $result; curl_close($ch); } } ?>

sendInvite:

 <?php error_reporting(E_ERROR | E_WARNING | E_PARSE | E_NOTICE); ini_set('display_errors', '1'); require_once 'Invitation.php'; $jsonText = file_get_contents('php://input'); if(empty($jsonText)) { $response = array("status"=>-2,"message"=>"Empty request"); die(json_encode($response)); } $json = json_decode($jsonText); $sender_id = $json-> sender_id; $user_name = $json -> user_name; echo $sender_id; echo $user_name; $invitation = new Invitation($sender_id,"","","",$user_name,"",""); $response = $invitation->sendInvite(); $message = 'Hi,add me to your unique contact list and you never need to update any changes anymore!'; $invitation->setNotification($message,$user_name); echo(json_encode($response)); ?>

Now getting output like this:

<!DOCTYPE html> <html lang=en> <meta charset=utf-8> <meta name=viewport content="initial-scale=1, minimum-scale=1, width=device-width"> <title>Error 404 (Not Found)!!1</title> <style> *{margin:0;padding:0}html,code{font:15px/22px arial,sans-serif}html{background:#fff;color:#222;padding:15px}body{margin:7% auto 0;max-width:390px;min-height:180px;padding:30px 0 15px}* > body{background:url(//www.google.com/images/errors/robot.png) 100% 5px no-repeat;padding-right:205px}p{margin:11px 0 22px;overflow:hidden}ins{color:#777;text-decoration:none}a img{border:0}@media screen and (max-width:772px){body{background:none;margin-top:0;max-width:none;padding-right:0}}#logo{background:url(//www.google.com/images/branding/googlelogo/1x/googlelogo_color_150x54dp.png) no-repeat;margin-left:-5px}@media only screen and (min-resolution:192dpi){#logo{background:url(//www.google.com/images/branding/googlelogo/2x/googlelogo_color_150x54dp.png) no-repeat 0% 0%/100% 100%;-moz-border-image:url(//www.google.com/images/branding/googlelogo/2x/googlelogo_color_150x54dp.png) 0}}@media only screen and (-webkit-min-device-pixel-ratio:2){#logo{background:url(//www.google.com/images/branding/googlelogo/2x/googlelogo_color_150x54dp.png) no-repeat;-webkit-background-size:100% 100%}}#logo{display:inline-block;height:54px;width:150px} </style> <a href=//www.google.com/> <span id=logo aria-label=Google></span> </a> <p> <b>404.</b> <ins>That’s an error.</ins> <p>The requested URL <code>/fcm/send</code> was not found on this server. <ins>That’s all we know.</ins> {"status":1,"message":"Invitation sent.","Invitation:":{"invitation_id":"547","date":"","invitee_no":"","status":"0","sender_id":"50","contact_id":"0","user_name":"siddhi","contact_name":""}}

  • You don't require require 'database.php'; on invitation page as this will create a fatal error. The same way you don't need to include require 'notification.php'; in sendInvite script. Commented Oct 14, 2016 at 5:44
  • I want to access database connection in other functions of invitation class. So for that I need 'database.php' in invitation class. can you please show me how can I do this? @ASR Commented Oct 14, 2016 at 5:51

Declare a class variable inside the notification file like this, and call database in the construct function. Use $this->dbConnection instead of $dbConnection all other places.

class notification { private $text,$user_name; public $dbConnection public function __construct() { $database = new Database(ContactsConstants::DBHOST, ContactsConstants::DBUSER, ContactsConstants::DBPASS, ContactsConstants::DBNAME); $this->dbConnection = $database->getDB(); } public function send($text,$userName) { $stmt = $this->dbConnection->prepare("Select device_id from Users where user_name =?"); $stmt->execute(array($userName)); $result = $stmt->fetch(PDO::FETCH_ASSOC); $token = $result["device_id"];

Then on Invitation php remove require 'database.php'; line and access databse functions using $this->dbConnection

 function sendInvite() { $stmt = $this->dbConnection->prepare("select * from Invitation where user_name =? and sender_id = ?"); $stmt->execute(array($this->user_name,$this->sender_id)); $rows = $stmt->rowCount();

And in the else condition, You dont need to redeclre the 'notification' class again, just access it like this.

 $resp = $this->send($message, $this->user_name);

Hope this helps.

Do I need to extend the notification class or not? @ASR
Yes you have to extend class Invitation extends notification

change your require to require_once to avoid include issues.
