Inserting a form into a block in Drupal?

Question

Is there any command or method that I can use to insert the contents of a form (e.g. the user registration form) into a block?

Answer 1

drupal_get_form($form_id) - put it in a module's hook_block ($op=='view') or even... shudder... inside a block with PHP filter on.

You need to find the form id first - look for a hidden input with the name form_id within the form. Its value should be the the form id.

Also, you could simply use the Form Block module.
