i created a banner that i want it to appear after 4 minutes.
I use modalbox to show the banner.
i need something like that
If customers_session_time > 4 minutes then show me the banner
But if i store customers_session_time to the database and write some code on PHP, then the user will have to refresh the page to see the banner.
If i use javascript's setTimeout() the thy timeout period will be refreshed every time the user refreshes the page...
Is there another way?
Not a very complete code, but you may catch an idea
<?php
session_start();
if( empty($_SESSION['time_session_started']) ){
$_SESSION['time_session_started'] = time();
}
$timeout = $_SESSION['time_session_started']+4*60 - time();
if( $timeout<0 ){
$timeout = 0;
}
?>
<script language="JavaScript">
<?php if( $timeout ){ ?>
setTimeout(function (){
showBanner();
},<?php echo $timeout*1000; ?>);
<?php }else{ ?>
showBanner();
<?php }
</script>
Remember the timestamp when user requests Your site in session.
Each time the user enters the site You will check if he is here for the first time or when did he came the latest. Then compute time spent already on the site in the session.
var timeSpentOnSites = (1000*60*4) - <?= $_SESSION['TIME_SPENT_ALREADY'] ?>;
$(document).ready(function(){
setTimeout(function(){
$('#banner').show();
},timeSpentOnSites < 0 ? 0 : timeSpentOnSites);
});
You cannot access any sessions in JavaScript as it is client sided.
What you can do is that AFTER the DOM has been sucessfully loaded you can use the setTimeout(); method and show the banner after 4 minutes.
$(document).ready(function(){
setTimeout(function(){
$('#banner').show();
},(1000*60*4));
});

i am looking for solution of my answer which is half completed i have to make the user logout from my website and i used your solution which is as follow:-
if( $_SESSION['last_activity'] < time()-$_SESSION['expire_time'] ) {
//have we expired?
//redirect to logout.php
header('Location: '.BASE_FULL_PATH.'/user/logout'); //change yoursite.com to the name of you site!!
} else{ //if we haven't expired:
$_SESSION['last_activity'] = time(); //this was the moment of last activity.
}
$_SESSION['logged_in'] = true;
$_SESSION['last_activity'] = time();
$_SESSION['expire_time'] = 24*60*60;
and it is working perfectly but i need to have an alert box when the session is about to expire.Try lot of stuff but doesn't help.Please reply and thanks for your brilliant demo
I know , this is not an efficient way, But you can try this.
try ajax, that runs a php file in server every 5 or 10 second time gap.
that ajax running php file contains session last_activity and expire_time comparing code,
<?php
$warning=100;
if( $_SESSION['last_activity']+warning < time()-$_SESSION['expire_time'] ) {
?>
<script type="text/javascript">
alert("Your session will expire soon!");
</script>
<?php
}
?>
You can set the variable $warning to adjust the alert message time.
Since your session expiry will reset every time you reload the page, then you can use the expiry time as the time argument of JavaScript's setTimeout() function.
var sessionExpiryTime = 24 * 60 * 60;
var sessionExpiryAlertTime = sessionExpiryTime - 5; //assuming we want the alert to show 5 seconds before expiry
setTimeout(function({
alert("Session about to expire!");
}, sessionExpiryAlertTime * 1000); //time is in milliseconds so we multiply by 1000
This works okay as long as the user has JavaScript enabled. If the user reloads the page, the expiry timer updates as per your php code and the setTimeout() function restarts.
The submit_pdf button saves up the information into the database and to avoid multiple clicks, i initially had disabled the submit button after one click, however now i would like to re enable the button after a timeout of 10 seconds. The part till where the submit button gets disabled is working fine, but if i try to add a delay of 10 seconds, it doesn't seem to work.It would be really helpful if you could help me out with this.
echo ' <script language="JavaScript" type="text/javascript">
//<![CDATA[
window.open(\'./index_pdf.php?'.$query_string.'\',\'Warehouse_ST\',\'location=no,menubar=no,resizable=yes,scrollbars=yes,status=yes,toolbar=no\');
id_form.submit_pdf.disabled=true;
window.alert("Data is stored in the database, Please do no click on Submit again without changing any information");
window.addEvent(\'domready''\',function()
{
var subber = $_REQUEST["submit_pdf"];
subber.addEvent( \'click' ,function() '
{
subber.set( \'value','Submitting...''\' ).disabled = true;
(function() { subber.disabled = false; subber.set(\'value','submit_pdf'\'); }).delay(10000); // how much time? 10 seconds
});
});
//]]>
</script>';
try using setTimeout()
define a function to enable the button, and then set a setTimeout():
function enableButton(){
$('#myButton').attr("disabled", false);
}
setTimeout(enableButton, 10000);
make sure to put the function name without quotes and without the "()"
I recommend to write JS code (aleation 's code is correct) and this PHP code.
PHP (store the time in a session var):
session_start(); //At the beginning of the PHP file
define("TIMEOUT", 10); //10 sec
//Check timeout
if (isset($_SESSION['expire'])) {
if ($_SESSION['expire']-time()>TIMEOUT) {
unset($_SESSION['expire']);
}
}
//Allow to do submit after 10 sec
if (!isset($_SESSION['expire'])) {
$_SESSION['expire']=time();
//Your submit code
}
This is because user can manipulate JavaScript and HTTP messages, but he/she can't manipulate php code.
I searched and find some examples to set idle timeout using jquery.
1 - Idle Timeout By Eric Hynds DEMO
2 - Idle Timer By paulirish
3 - Fire Event When User is Idle / DEMO HERE
4 - detect user is active or idle on web page
5 - Comet Long Polling with PHP and jQuery
6 - detacting idle timeout javascript
... And several other similar examples
Between these examples number 1 is better for i need because i need to auto logout user with any confirm alert after X minutes (logout.php or any url). but this method Not suitable for server. problem is : this jquery code send ping to any url : keepAlive.php in loop/pooling for request OK text . see firebug screen :
how to fix this ?
So, other examples only printed Idle/No Idle and not work with alert confirm and auto logout ( logout.php or any url ) now really better way to choose idle timeout using jquery/Php ?
Thanks
I use a meta refresh element in the head section to auto-direct users to the logout page after X number of seconds. Below will automatically send a user to the logout page after 20 minutes of staying on the same page:
<meta http-equiv="refresh" content = "1200; url=http://www.site.com/user/logout">
This works, is (mostly) supported cross-browser, does not rely on JavaScript being enabled and is pretty easy to implement.
If your site has users that stay on the same page for extended periods of time (with interaction taking place through JS, for instance), this solution will not work for you. It also does not allow any JS code to be run before redirection takes place.
Here is my approach that I applied to build a simple auto-logout feature with JavaScript and jQuery. This script was constructed for use with webpages that will automatically go to the logout page when mouse movement is not detected within 25 minutes.
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script type="text/javascript" language="javascript">
var idleMax = 25; // Logout after 25 minutes of IDLE
var idleTime = 0;
var idleInterval = setInterval("timerIncrement()", 60000); // 1 minute interval
$( "body" ).mousemove(function( event ) {
idleTime = 0; // reset to zero
});
// count minutes
function timerIncrement() {
idleTime = idleTime + 1;
if (idleTime > idleMax) {
window.location="LogOut.php";
}
}
</script>
<script>
var idleMax = 5; (5 min)
var idleTime = 0;
(function ($) {
$(document).ready(function () {
$('*').bind('mousemove keydown scroll', function () {
idleTime = 0;
var idleInterval = setInterval("timerIncrement()", 60000);
});
$("body").trigger("mousemove");
});
}) (jQuery)
function timerIncrement() {
idleTime = idleTime + 1;
if (idleTime > idleMax) {
window.location="Your LOGOUT or Riderct page url here";
}
}
</script>
Easy and simle
var autoLogoutTimer;
resetTimer();
$(document).on('mouseover mousedown touchstart click keydown mousewheel DDMouseScroll wheel scroll',document,function(e){
// console.log(e.type); // Uncomment this line to check which event is occured
resetTimer();
});
// resetTimer is used to reset logout (redirect to logout) time
function resetTimer(){
clearTimeout(autoLogoutTimer)
autoLogoutTimer = setTimeout(idleLogout,5000) // 1000 = 1 second
}
// idleLogout is used to Actual navigate to logout
function idleLogout(){
window.location.href = ''; // Here goes to your logout url
}
Let me post the code first.
function alertCallback<?=$position_info['id']?>()
{
var id = <?=$position_info['id']?>;
var itemname= '<?=$na?>';
<?PHP if($position_info['name'] == $wposition){ ?>
var reward = '<?= $itmname ?>';
$('#selected_item').html(''+itemname+reward);
<?PHP item_add($_SESSION['userid'],$itmid,1); } else { ?>
var noreward = 'You Found Nothing!';
$('#selected_item').html(''+itemname+noreward);
<?PHP } ?>
}
The above is working to an extent. The page is a image map where if you click on the right spot then you get an item. It is currently working where if you click on the right spot you get the item. Or get told you found nothing.
The problem I have is that the page reloads to set new positions
<script type="text/javascript">
//one seconds=1000 micro seconds
setInterval(function() {
$('#load').load('itemclick_ajax.php');
},60000);
</script>
but another item is won as long as the page is displayed. Any ideas on how to stop this occuring. If i keep the browser showing the page then im running up to thousands of items won.
Are you trying to stop the page reload?
Try adding "return false;" at the end of your Javascript function.
Assume that you are doing a banking application. If users are logged into your site, how to detect their inactivity and ask them to log out if they remain inactive for a period of time? Inactive here means they have either switch to other tabs, or not touching the browser application.
I guess think I can do this by registering every mouse movement or keyboard movement when users are doing on EVERY page of my application. But the code would be very ugly and hard to maintain. Is there other more elegant ways of doing this?
This is the code I use. It is not mine, but I did modify it to it's 'perfection'.
// Add the following into your HEAD section
var timer = 0;
function set_interval() {
// the interval 'timer' is set as soon as the page loads
timer = setInterval("auto_logout()", 10000);
// the figure '10000' above indicates how many milliseconds the timer be set to.
// Eg: to set it to 5 mins, calculate 5min = 5x60 = 300 sec = 300,000 millisec.
// So set it to 300000
}
function reset_interval() {
//resets the timer. The timer is reset on each of the below events:
// 1. mousemove 2. mouseclick 3. key press 4. scroliing
//first step: clear the existing timer
if (timer != 0) {
clearInterval(timer);
timer = 0;
// second step: implement the timer again
timer = setInterval("auto_logout()", 10000);
// completed the reset of the timer
}
}
function auto_logout() {
// this function will redirect the user to the logout script
window.location = "your_logout_script.php";
}
// Add the following attributes into your BODY tag
onload="set_interval()"
onmousemove="reset_interval()"
onclick="reset_interval()"
onkeypress="reset_interval()"
onscroll="reset_interval()"
Good luck.
If the user is requesting new pages/data from your server on a regular basis, then adjusting the session timeout in PHP should work for this (assuming you are using PHP sessions).
If the concern is that they could be sitting on one page for a good length of time with no trips to the server (e.g. filling out a long form), and you want to distinguish between this and the user simply switching to another window, you could do something like use javascript to request some data using XMLHTTPRequest every five minutes or so to keep the session alive. You could use the window.focus and window.onblur events in javascript to stop and restart this mechanism (I think there are some differences for IE, there is a good explanation here).
A very easy and effective way of doing this is by placing something like this in your HTML HEAD section:
<META HTTP-EQUIV="refresh" CONTENT="1800;URL=logout.php?timeout">
Replace the logout.php?timeout with the appropriate script .. In the example above, if ?timeout is in the query string, I show them a login page with information indicating that they've been logged out due to inactivity.
Replace 1800 with the time in seconds that you wish to allow them to stay inactive before automatically logging them out. Set this to the same time that you have your session expiration set to.
Edit - Another easy mechanism to implement is to have a session variable called last_time, or last_activity, or something along those lines, and set it to a timestamp everytime there is activity. In most of my stuff, I have a general include file that I do this in. In the same file, you could check to ensure that it's within the constraints that you've set forth for an active session. If it's been too long -- just do a 300 redirect to the logout page and display the appropriate inactivity message there.
Good luck!

We can improve our codes to jquery now
idleTime = 0;
$(document).ready(function() {
var idleInterval = setInterval("timerIncrement()", 60000); // 1 minute //60000
$(this).mousemove(function(e) {
idleTime = 0;
});
$(this).keypress(function(e) {
idleTime = 0;
});
});
function timerIncrement() {
idleTime = idleTime + 1;
if (idleTime >= 5) {
window.location = $('#base_url').val() + 'home/logout_user';
}
}
You can do it more elegantly with underscore and jquery javascript libraries-
$('body').on("click mousemove keyup", _.debounce(function(){
// logout user here
}, 1800000)) // 30 minutes inactivity
It depends how they are "logged in" in the first place. Doesn't the session expiration on the server do this for you? If you really want to do it manually then you could use some javascript in a setTimeout, but thats ugly
Usually the session lifetime is used to determine whether a user is logged in or not. So you could set a flag in the session that represents this state. And if it’s missing (either the user didn’t log in yet or the session timed out), he is considered as not logged in.
You can have a bit of javascript that checks the server every x minutes to see when the user's last activity was. Shouldn't be more than a few lines of code. I would also add a meta refresh if the user has javascript disabled.
I took the timestamp 'now' and check on each click if the delay is less than 3000 seconds or more than billions of seconds, which means that the user just logged in, if it's not it will redirect to logout
var time = 0;
$(document).on('click', function() {
var now = Date.now() / 1000 | 0;
if (now - time < 3000 || now - time > 1480000000) {
time = now;
} else {
window.location.replace("http://url");
}
})
put in header of your java script page.. if you want to avoid the backend calls
Below is the snip-let under script tag :
<script>
var idleTime = 0;
function func(){
console.log(idleTime);
$(this).keypress(function(e) {
idleTime = 0;
});
$(this).click(function(e) {
idleTime = 0;
});
timerIncrement();
}
function timerIncrement() {
console.log("timerIncrement");
console.log(idleTime);
idleTime = idleTime + 1;
if (idleTime >= 1) {
console.log(window.location);
logoutcall(); //API call
window.location = window.location.origin+"/riskoffice_UI/Login";
}
}
setInterval(func,1800000) //Runs the "func" function every second
</script>
Update : localStorage can be use to keep idle time for the application with multiple tabs are opened.
// Check browser support
if (typeof(Storage) !== "undefined") {
// Store an item to localStorage
localStorage.setItem("timeIdle", "0");
console.log(localStorage.getItem("idleTime"));
// Retrieve the added item
} else {
//display this message if browser does not support localStorage
console.log("Sorry, your browser does not support Web Storage.");
}
function func(){
$(this).keypress(function(e) {
localStorage.setItem("timeIdle", "0");
});
$(this).click(function(e) {
localStorage.setItem("timeIdle", "0");
});
timerIncrement();
}
function timerIncrement() {
var timeIdle = localStorage.getItem("timeIdle");
timeIdle = parseInt(timeIdle) + 1;
if (timeIdle >= 1) {
logoutCall();
window.location = window.location.origin+"/riskoffice-ui/Login";
}
localStorage.setItem("timeIdle", timeIdle.toString());
}
setInterval(func,1800000); //Runs the "func" function every second
