Pass Json object to other class method - php

Question

I'm trying to pass json decoded object to method of a class. But when I try to access properties of that object, it gives notice: Trying to get property of non-object php. But when I write that object variable to a file it shows all data.
I'm trying to update hubspot data using its api when a webhook event is sent by memberpress plugin.
Here is what i'm doing:
File: hubspotsync.php
require_once 'class-synchronize.php';
class HubspotSync{
public function init()
{
$encoded_data = file_get_contents('php://input');
if( $encoded_data != '' ){
$data = json_decode($encoded_data);
$this->perform_action($data);
}
}
private function perform_action($data)
{
$synchronize = new Synchronize();
$synchronize->perform_sync($data);
unset($synchronize);
}
}
$sync = new HubspotSync();
$sync->init();
unset($sync);
File : class-syncronize.php
class Synchronize{
public function perform_sync($eventobj)
{
// If I fwrite this $eventObj to a file, it looks like as below. but gives an notice on next code. why???
$event_type = $eventobj->event; // This line gives the notice.
}
}
$eventobj looks like this:

Answer 1

var_dump( $eventObj ) and make sure that the event property actually exists on that object. It might be $eventObj['event'] or something weird like that. The error is telling you that event doesnt exist on your $eventObj
