hook_forms()

7

hook_forms($form_id, $args)

Map form_ids to builder functions.

This hook allows modules to build multiple forms from a single form "factory" function but each form will have a different form id for submission, validation, theming or alteration by other modules.

The callback arguments will be passed as parameters to the function. Callers of drupal_get_form() are also able to pass in parameters. These will be appended after those specified by hook_forms().

See node_forms() for an actual example of how multiple forms share a common building function.

Return value

An array keyed by form id with callbacks and optional, callback arguments.
