Hello,

I'm attempting to switch out the current theme with a completely different one whenever at the login screen. However testing the concept of switching themes on the fly doesn't seem to be working...

class PageExtension extends Extension
{
    public function onBeforeInit()
    {
        Debug::message(SSViewer::get_theme_folder());

        SSViewer::set_theme('login-theme');

        Debug::message(SSViewer::get_theme_folder());

        parent::init();
    }
}

---
Name: custom-login
After:
  - 'framework/*'
  - 'cms/*'
---
Page_Controller:
  extensions:
    - PageExtension

Shows the theme folder is switching, but the default theme is still being loaded. Do I need to call re-render or something similar?

Any ideas on how to go about this?

Yeah, that's not particularly a good idea.

Just make a template Security.ss
and/or Security_login.ss

Place it in the 'main' templates folder (ie, not Layout).

?flush

That isn't what I'm trying to achieve so isn't really of much help.

We run about 15 different sites on the same instance, each with their own theme and own 'core'. The goal here is to create a unified login screen as a module. So I want to override every other Security_login.ss, hence the extension.

The reasons aside, should the code above not be working correctly?

No.

Security:
  template_main: MyCompanysLoginSplash

Worked perfectly, thanks for the answer.

You're welcome :)
