A plugin for the Pico CMS which makes the query params available in the twig templates.
In Pico CMS the first parameter is the content url and gets stripped so it won't appear in the array of query parameters.
The query parameters are stored in an associative array. No-value parameters get the boolean value TRUE.
The parameters are accesible in the twig templates via queryParams.
Just copy the php file into the plugins folder. The plugin is configured to be enabled by default.
