This filter will automatically add css file with the name of current module.

It's great to have these files saved separately that to have one huge file. (And demo of CSSEdit doesn't allow saving files bigger than 2.5k chars :D)

Just create your cssAdderFilter.class.php, and add it to your filters.yml. Clear cache and you are ready to go.

<?php 
 
class cssAdderFilter extends sfFilter
{
 
    public function execute( $filterChain )
    {
        $context = $this->getContext();
        $request = $context->getRequest();
        $response = $context->getResponse();
 
        $module = $request->getParameter("module");
 
        $path_to_web = sfConfig::get("sf_web_dir");
        $path_to_css = $path_to_web . "/css/" . $module . ".css";
 
        if (file_exists($path_to_css))
        {
            $response->addStylesheet($module.".css");
        }
 
        $filterChain->execute();
    }
 
}
