Choice not stored between sessions

I have updated your wp_user_stylesheet_switcher.php file and it now works.
But next update will erase it I guess.
Is there a way to make an add_filter in functions.php for this ?

public function wp_user_stylesheet_switcher_addcss()
{
$stylesheet_choice = $settings['default'];
if(isset($_COOKIE['MYCOOKIE'])) {
   $_SESSION['user_stylesheet_switcher'] = $_COOKIE['intranet_theme'];
		}
if (isset($_POST['user_stylesheet_switcher_choice']))
{
   // User chose a stylesheet in the switcher
   $stylesheet_choice = $_POST['user_stylesheet_switcher_choice'];
   setcookie('MYCOOKIE', $stylesheet_choice, time()+1209600, '/', 'MYURL', false);

...
}

For those interested:
In my child theme, in header.php, just place this

if(isset($_COOKIE['MYCOOKIE']))
 	{
		$_SESSION['user_stylesheet_switcher'] = $_COOKIE['MYCOOKIE'];
	}
if (isset($_POST['user_stylesheet_switcher_choice']))
	{
		$stylesheet_choice = $_POST['user_stylesheet_switcher_choice'];
		setcookie('MYCOOKIE', $stylesheet_choice, time()+1209600, '/', 'MYURL', false);
		$_SESSION['user_stylesheet_switcher'] = $stylesheet_choice;
	}

So, nothing changed in plugin core !

Hi! I’m working on an update, so I’ll add a setcookie to my plugin.

Thanks for the idea.

Nice ??

Hi kiboost,
I just updated my plugin. I made many important changes, the main one is that the user choice is now saved in a cookie using javascript.
Could you test the new version to see the user choice is preserved on your site too.
