This module enables basic CAPTCHA functionality: administrators can add a CAPTCHA to desired forms that users without the 'skip CAPTCHA' permission (typically anonymous visitors) have to solve.

Code

function captcha_examples($module = NULL, $challenge = NULL) {
  if ($module && $challenge) {

    // generate 10 examples
    $output = '';
    for ($i = 0; $i < 10; $i++) {

      // generate CAPTCHA
      $captcha = call_user_func_array($module . '_captcha', array(
        'generate',
        $challenge,
      ));
      $form = $captcha['form'];
      $id = "captcha_examples_{$module_}{$challenge_}{$i}";
      drupal_process_form($id, $form);
      $output .= drupal_render_form($id, $form);
    }
  }
  else {

    // generate a list with examples of the available CAPTCHA types
    $output = t('This page gives an overview of all available challenge types, generated with their current settings.');
    foreach (module_implements('captcha') as $module) {
      $challenges = call_user_func_array($module . '_captcha', array(
