Thanks Ken & Nancy - I'm now wondering how I've been writing modules for almost a year without realising the whole $node object is available from $form =).

Check $form[#node]->type. If not empty, use that string.

I'm writing a module that adds a field to the create/edit forms for nodes of certain types - the actual types can be chosen by the user. There are loads of ways to identify the type of the current node from within hook_form_alter(), but is there an accepted standard way to do it?

If I use $form['type']['#value'] I get "Notice: Undefined variable" warnings as my local server's error reporting is very verbose. I know I could change the error reporting level, but surely it's better practice to try and kill the bug?

And if I use $form_id I have to use nodetype_node_form and convert it to nodetype - and, as an aside, I can't find a PHP function to do this cleanly.

So, what's the accepted way to do this?
