Im using LoaderAbstract to add some custom CSS, cant seem to figure out how to limit the file inject to a specific app.

Dispatcher doesn't initialize.

Thanks.

What is the code you're currently using?

<?php

namespace IPS\galleryai\extensions\core\Loader;

use IPS\Extensions\LoaderAbstract;
use function defined;

/* To prevent PHP errors (extending class does not exist) revealing path */
if ( !defined( '\IPS\SUITE_UNIQUE_KEY' ) )
{
    header( ( $_SERVER['SERVER_PROTOCOL'] ?? 'HTTP/1.0' ) . ' 403 Forbidden' );
    exit;
}

class CustomCSS extends LoaderAbstract
{
    public function css(): array
    {
        // Manually construct the URL using the base URL from IPS settings
        $baseUrl = \IPS\Settings::i()->base_url;
        $url = rtrim($baseUrl, '/') . '/applications/galleryai/dev/css/front/custom.css';

        return [
            [(string) $url]
        ];
    }
}

That works but is system wide.

public function getLocationData(): array
{
    $app = Dispatcher::i()->application ? Dispatcher::i()->application->directory : null;
    $module = Dispatcher::i()->module ? Dispatcher::i()->module->key : null;
    $controller = Dispatcher::i()->controller ?? null;
    $id = \IPS\Request::i()->id ? (int)\IPS\Request::i()->id : null;

    return array(
        'app' => $app,
        'module' => $module,
        'controller' => $controller,
        'id' => $id
    );
}

That retruns null.

This is the code I use in one of my apps, I've adjusted it to use the values you posted above:

	/**
	 * Additional CSS files to load
	 *
	 * @return array<string|Url>
	 */
	public function css(): array
	{
		$cssFiles = [];
		
		# Only add to the frontend, and for a specific app
		if ( \IPS\Dispatcher::checkLocation( 'front', 'galleryai' ) )
		{
			$cssFiles[] = \IPS\Theme::i()->css( 'custom.css', 'galleryai', 'front' );
		}
		
		return $cssFiles;
	}

This will only add the CSS file inside the galleryai app pages. If you want it inside another application, for example, gallery, you must change the IF check to:

if ( \IPS\Dispatcher::checkLocation( 'front', 'gallery' ) )

And so on.

You can also further specify a module and controller value in the checkLocation() call.

Beautiful, thank you very much sir.

Oh spoke to soon, it runs but shows everywhere.

With the checkLocation line it shouldn't show everywhere. 🤔

On what page(s) do you want to include the CSS file and how did you edit the line to match?

Yes, bizarre.

So thats all good but also displays in forum app.

Strange indeed. 🤔

Looks like a bug, I'm logging it internally.

Thank you.
