Drupal: Display success/error message

Question

how can I show users success/error messages without creating a node for it?

Thanks in advance!

Answer 1

drupal_set_message($msg, $type = 'status'); lets you set a message, it will be displayed automatically on the next (or current) page the user visits.

The optional second argument lets you choose between an informational message (status), a warning (usually yellow) or an error (red).

See the docs: http://api.drupal.org/api/function/drupal_set_message/6
