Demonstrate validation of a textfield using AHAH. This approach allows 'live' validation of a field which degrades gracefully when JavaScript is not available.

Code

function ahah_example_simple_validation_validate(&$form, &$form_state) {
  $words = explode(' ', $form_state['values']['two_words_required']);
  if (count($words) < 2) {
    form_set_error('two_words_required', t('You have to enter at least two words'));
  }
}
