Returns a renderable form array for a given form ID.

This function should be used instead of drupal_build_form() when $form_state is not needed (i.e., when initially rendering the form) and is often used as a menu callback.

Parameters

$form_id: The unique string identifying the desired form. If a function with that name exists, it is called to build the form array. Modules that need to generate the same form (or very similar forms) using different $form_ids can implement hook_forms(), which maps different $form_id values to the proper form constructor function. Examples may be found in node_forms(), and search_forms().

...: Any additional arguments are passed on to the functions called by drupal_get_form(), including the unique form constructor function. For example, the node_edit form requires that a node object is passed in here when it is called. These are available to implementations of hook_form_alter() and hook_form_FORM_ID_alter() as the array $form_state['build_info']['args'].

Return value

The form array.
