Keep Session Alive

[bumba000]

Hello All,
Still working on 1.5.8a w/PHP 8.2.4. I have achieved a session keep alive which works fine, but has one major issue. lol

So I'm activating the function by:
$(document).ready(function(){
timerKeepAlive();
});

The function:
function timerKeepAlive() {
setInterval(function() {
$.ajax({url: location});
}, 300000); //five minutes
}

On a PC this works forever as long as the browser isn't closed. On a mobile it works forever while browsing other tabs. However, when I hit the power button to (for lack of a better term) 'rest/sleep' the phone, the session dies and I come back to an empty cart.

How can I get a visitor's cart to survive a sleeping cellphone?

Thank you,
John

Can also force login. Items in the cart of a logged in customer, generally stay with the customer.

Yeah I know I just don't want to force a visitor to create an account. Thanks tho.

Hey Lat9. Any idea why keep cart wont let the customer empty the cart? I haven't tried logging in, but a visitor creates a cart and all but the last item can be deleted from the cart. I disable the plugin and I can delete the last item in cart.

1.5.8a on 8.4.2

Thanks again,
John

I'm pretty sure I have this ironed out. In the file includes/classes/class.savecart.php

Just inside of the folliwing statment
if (isset($_COOKIE['cart'], $_COOKIE['cartkey']) && isset($_SESSION['cart']) && empty($_SESSION['cart']->contents)) {

I added...
if($_SESSION['cart']->count_contents() === 0){
$this->expireKeepCartCookie();
return;
}

Seems to be working. I'll post back if I find that my solution is causing a problem. If you come up with a better solution please let me know before this goes live. ;)

Thanks again,
John

Nope. That's not working. Doesn't restore the cart once the php session expires.

[bumba000]

It's funny i guess that I thought my above listed solution might work. Asking if the cart's empty inside of an if cart empty ? lol. Well I still haven't quite found a solution, but I realize that there's a few things firing off before getting to the class.savecart file. So the cart does actually become empty after the classes/shopping_cart.php ->remove function is run. I am in that remove function trying to unset the cookie, but I just haven't nailed it down. Am I at least on the right path here?

Thanks again,
John

PS. Just to recap.
ZC 1.5.8 on PHP 8.4.2.
ZC session time (for testing) = 120 sec
Cookie life = 30 days
Add items to cart, close browser come back an hour later everything's there.
Deleting items from shopping cart works until the very last item. The last item can not be removed from cart.

[bumba000]

Another failed attempt...
Inside the remove function of classes/shopping_cart.php just before the closing curly of the function I added the following...

if(empty($_SESSION['cart']->contents)){
$_SESSION['cookieremover'] = 'remove';
}


Then in the class.savecart.php file I changed

if ($cart_contents === false) {
$this->expireKeepCartCookie();
return;
}

to this

if ($cart_contents === false || (isset($_SESSION['cookieremover']) && $_SESSION['cookieremover'] == 'remove')) {
$_SESSION['cookieremover'] = '';
$this->expireKeepCartCookie();
return;
}


So with this in place, I add an item to the cart then delete the item. It does get removed from cart, but on next page load the item is restored. I guess a week is long enough. I'll fool around with it a little more today, but ultimately I feel i'm gonna have to pull the plug on this plugin until a solution is found.

Thanks again for all the help.

Best,
John
