CAPTCHA (fieldset) theming

I'm not sure what you are talking about.

With the option "Add a description to the CAPTCHA" you can add a description to the fieldset.

If you are talking about a HTML-legend on a fieldset, then there should be a legend "CAPTCHA" by default. This is not configurable through the CAPTCHA admin interface.

However, in the CAPTCHA 6.x-2.x branch, the whole CAPTCHA widget (and optional fieldset) is rendered with a theme function (see captcha.module around line 265):

/**
 * Theme function for a CAPTCHA element.
 *
 * Render it in a fieldset if a description of the CAPTCHA
 * is available. Render it as is otherwise.
 */
function theme_captcha($element) {
  if (!empty($element['#description']) && isset($element['captcha_widgets'])) {
    $fieldset = array(
      '#type' => 'fieldset',
      '#title' => t('CAPTCHA'),
      '#description' => $element['#description'],
      '#children' => $element['#children'],
      '#attributes' => array('class' => 'captcha'),
    );
    return theme('fieldset', $fieldset);
  }
  else {
    return '<div class="captcha">'. $element['#children'] .'</div>';
  }
}

In your theme you can override this in the standard Drupal theming way, and change the legend ('#title' property) of the fieldset to your liking.

hope this helps.

you're welcome

is there a way to change form label ("Math question" for instance) and text without changing module files?

i see that they're generated by function captcha_captcha in captcha.module but i think it's not themeable, isn't it? (although it is translatable).

thank you

There are several ways to achieve this (hook_form_alter with a custom module, custom theming), but the easiest is probably the string overrides module (or the locale module from core, when you are using multiple languages on your site)

I works for me. Thanks soxofaan

Ok slightly different approach to this question.

At the moment the maths element is not correctly accessible in that the actual maths question 1+2 = is not part of the element thus is not associated with the input filed and not read out to the user.

How can I amend the form to include the maths question inside the elements?
