Updated to add the include path for pre-3.0 (it'll autoload in 3.0).

I need also to add $category->alias= 'my-alias';

You can use it if you want to specify the alias, otherwise $category->check() will automatically generate the alias.

Exactly how does the tree placement work? Will $category->setLocation(1, 'last-child'); just add it as the last child of the root category?

Correct. For a new component, this should be the default action. I have some other code saved that will set the location as the last child of another category, but you have to do some other lookups to get the ID for that category.

I see. Is '1' always the root category? it occurs to me that JTableNested has a method called getRootId for a reason.

1 should always be the ID of the root category, at least in the CMS. You have to know the ID of the parent item you want to be a child of, so I can hard code it to 1 for CMS instances and be OK. Using getRootId should work also if you need it to.

Is this ok for joomla2.5? Because i copy it and It din't create any new category

Just wondering why you have $db = JFactory::getDbo(); in this?
