I'm working on a local plugin and i need to add a new setting (a text input field) to the course settings page (/course/edit.php). Is it possible to do that from a local plugin, without changing the /course/edit.php and /course/edit_form.php files?
The documentation on local plugins (http://docs.moodle.org/dev/Local_plugins) says that a local plugin can add admin settings to any settings page - loaded last when constructing admin tree. I think it means that I can use a local plugin to add a new text input field to the course settings page, for example.
Basicaly I need a way of adding new fields to a settings page (like course settings page, and later on course category settings page, etc) without making changes to core files. Is this possible?
