Dear All,

I try to have the theme selected in the calling URL via http://localhost/demo/?theme=test01 and the code

if(isset($_GET['theme'])) {
   $_SESSION['theme'] = $_GET['theme'];
}

$theme = isset($_SESSION['theme']) ? $_SESSION['theme'] : 'blackcandy';

SSViewer::set_theme($theme);

in _config.php.
The theme is selected correctly but not passed on to the subsequent pages. So when I click "About Us" the theme is reverted back to my default blackcandy. According to the posts in this forum this should not happen ... any ideas?
I am on SS2.3.0

Ciao, Mathias

Try using the build in Session methods. Session::set('theme', 'mytheme'); Session::get('theme') rather then the $_SESSION directly

Salut Will,

I tried it and got a strange reaction:
I inserted ONLY the line

Session::set('theme', 'mytheme');

ind

_config.php

and immediately the following error appears when calling the page

Warning: No current controller available in E:\wamp\www\SilverStripe\sapphire\core\control\Controller.php on line 346

Fatal error: Call to a member function getSession() on a non-object in E:\wamp\www\SilverStripe\sapphire\core\Session.php on line 57

I interpreted your suggestion to use this:

Session::set('theme', 'ncse01');
$theme = 'ncse01';
if(isset($_GET['theme'])) {
   Session::set('theme', $_GET['theme']);
   $theme = $_GET['theme'];
}

SSViewer::set_theme($theme);

but this gives the error above as well. I am quite new to php ...

Ciao, Mathias

Salut Will (or others who have access to the source),

could you please publish the _config.php of http://demo.silverstripe.org?

Ciao, Mathias

Salut,

just for information: I fixed the issue by setting a cookie that holds the actual theme and reading it back from $_COOKIE in _config.php:

if(isset($_GET['theme'])) {
	$mytheme = $_GET['theme'];
	setcookie("SessionTheme", $mytheme);
} else {
	if (isset($_COOKIE['SessionTheme'])) {
		$mytheme = $_COOKIE['SessionTheme'];
	} else {
		$mytheme = 'blackcandy';
	}
}
SSViewer::set_theme($mytheme);

(I am new to php, so the code can probably be written much nicer)

Ciao, Mathias
