Check Member / User Online or Offline Status
This article is also available in the following languages:
The following piece of code will calculate the last visited time of a Member/User and calulate the time difference with current time. And if the Member/User last visited time is greater than 10 minutes then that will be considered OFFLINE otherwise ONLINE.
I was just searching for a time difference code in Bakery but couldn't find the simple code. I have developed and used the following code to calculate the time whether the User/Member is online or offline.
Only 3 Steps to follow.
1. Make a field last_visit (DATETIME) in MEMBER Table.
2. For APP CONTROLLER.
3. Simply use the following code in your .ctp file according to your demand.
Only 3 Steps to follow.
I am assuming that you have the table named MEMBER (you can customize it according to your requirements)
1. Make a field last_visit (DATETIME) in MEMBER Table.
2. For APP CONTROLLER.
Component Class:
<?php
class AppController extends Controller {
/*
*
* beforeRender() function will run on every visit of the website
*/
function beforeRender()
{
### UPDATE LAST VISIT ###
$online_offline_status = 0;
if ($this->Session->check('userId')==true){ // Checking for the SESSION - Proceed only if MEMBER/USER is logged in.
$this->loadModel('Member'); // Loading MEMBER Model
// UPDATE MEMBER VISIT TIME
$last_visit = date('Y-m-d H:i:s', time());
$this->Member->updateAll(array('Member.last_visit' => '"'.$last_visit.'"'), array('Member.id' => $this->Session->read('userId')));
// GET TIME DIFFERENCE
$member_last_visit = $this->Member->find('first', array('conditions' => array('Member.id' => $this->Session->read('userId'))));
$current_time = strtotime(date("Y-m-d H:i:s")); // CURRENT TIME
$last_visit = strtotime($member_last_visit['Member']['last_visit']); // LAST VISITED TIME
$time_period = floor(round(abs($current_time - $last_visit)/60,2)); //CALCULATING MINUTES
//IF YOU WANT TO CALCULATE DAYS THEN USER THIS
//$time_period = floor(round(abs($current_time - $last_visit)/60,2)/1440);
echo $time_period;
if ($time_period <= 10){
$online_offline_status = 1; // Means User is ONLINE
} else {
$online_offline_status = 0; // Means User is OFFLINE
}
}
$this->set('online_offline_status', $online_offline_status);
}//end beforeRender()
}
?>
3. Simply use the following code in your .ctp file according to your demand.
View Template:
<!-- IF USER IS OFFLINE -->
<?php if ($online_offline_status == 0){ ?>
<span style="color:#FF0000;">(Member/User is Offline)</span>
<!-- IF USER IS OFFLINE -->
<?php } else if ($online_offline_status == 1) {?>
<span style="color:#669900;">(Member/User is Online)</span>
<?php }?>
