Woocommerce Set Cart Expiration Interval

Question

I need to increase the expiration time of Woocommerce cart to 72 hours.

I've tried the solution suggested here: set wordpress woocommerce cart expiration

But I can't see any result :( Can anyone help me to get this working?

Thanks

-- Edit: Code snippet ---

add_filter('wc_session_expiring', 'filter_ExtendSessionExpiring' );
add_filter('wc_session_expiration' , 'filter_ExtendSessionExpired' );

function filter_ExtendSessionExpiring($seconds) {
    return (60 * 60 * 24 * 4) - (60 * 60);
}
function filter_ExtendSessionExpired($seconds) {
   return 60 * 60 * 24 * 4;
}

Answer 1

I had exactly this problem in a multi site set up and built a plugin to solve this. You can get the plugin here http://mtrl.co.uk/shop/product/woocommerce-cart-lifespan-settings-plugin/

The filter must return 72 hours, in seconds.

add_filter('wc_session_expiring', 'filter_ExtendSessionExpiring' );
add_filter('wc_session_expiration' , 'filter_ExtendSessionExpired' );

function filter_ExtendSessionExpiring($seconds) {
    return 60 * 60 * 71;
}
function filter_ExtendSessionExpired($seconds) {
   return 60 * 60 * 72;
}
