PHP automatic logout without having to refresh the page

rated 0 times [ 51] [ 6] / answers: 1 / hits: 16878 / 10 Years ago, wed, february 11, 2015, 12:00:00

I am writing a project in PHP, JavaScript and HTML. I have successfully done the automatic logout when the user is idle for 1 minute. But the problem comes in that I have to refresh the page for it to be executed and log me out.

Can somebody help me so that immediately 1 minute is over and the user is idle, the code will be executed and it will take me to the login page without me refreshing it?

Here is my code:

// check to see if $_SESSION['timeout'] is set

if(isset($_SESSION['timeout']) ) {

$session_life = time() - $_SESSION['timeout'];

if($session_life > $inactive)

    {  





 echo<script type='text/javascript'> 

window.alert('Your Session got Expired');

</script>;

header(Location: logout.php);

}

}



$_SESSION['timeout'] = time();

//Continuation of other codes

I guess the best way to implement is by using the combination of JS and PHP

check.php

if(isset($_SESSION['timeout']) ) {

$session_life = time() - $_SESSION['timeout'];

if($session_life > $inactive) echo 0;



else echo 1;

}



$_SESSION['timeout'] = time();

.js

$(document).ready(function(){

  setTimeout(function(){

        $.get(check.php, function(data){

        if(data==0) window.location.href=logout.php;

        });

    },1*60*1000);

});

Or just wrap it in setInterval(function(){},1*60*1000) instead of setTimeout() if you want it to be checked after every one minute.

$(document).ready(function(){

setInterval(function(){

        $.get(check.php, function(data){

        if(data==0) window.location.href=logout.php;

        });

    },1*60*1000);

});
