On a site I would like a "quick entry" form for a custom content type on the front page, while also keeping the "normal" non-customized "node/add/mycontenttype" form. I'm able to customize the "normal" form by using the theme_hook function returning the proper array which points to my function that renders the form ('template' => 'some-node-form').
But ideally I would like to keep both versions of the form, rendering my customized form on the frontpage in a block, and with the normal form at the normal place "node/add/mycontenttype". I figured I could try to detect at runtime in the 'some-node-form' function if for instance it was invoked through a special path "node/add/mycontenttype/frontpage", by passing a variable or similar. I haven't quite managed to do this yet, but at least in theory it should be doable.
But do any experienced Drupal developers have better ways of accomplishing what I'm doing, things like having multiple paths pointing to different template rendering functions or similar?
