How to move captcha fieldset

Question

I am using the Captcha module to protect my site against spam.

I have put everything else on my form inside a fieldset which is collapsible by default. Howeve, the captcha fieldset is the only thing being output last and outside of the fieldset. Using hook_form_alter and dsm($form) I cannot see the captcha fieldset so i'm guessing it's not part of the form??

after scouring through the code i have discovered it's created via a theme function (theme_captcha) which I can override inside my template.php.

I would like to know how can I bring this fieldset inside the form just above it? Look at the screenshot attached.

Thanks

Answer 1

The fact that you are unable to view the $form['captcha'] element is due to the form workflow: CAPTCHA is added after your hook_form_alter.

In hook_form_alter documentation, it is stated that the order is

1. module_A_form_alter
2. module_A_form_BASE_ID_alter
3. module_A_form_FORM_ID_alter
4. module_B_form_alter
5. module_B_form_BASE_ID_alter
6. module_B_form_FORM_ID_alter

etc.

And

The module order is determined by system weight, then by module name.

CAPTCHA module uses hook_form_alter to add CAPTCHA element on the fly. So simply alter your module's weight to place it after CAPTCHA module.

Answer 2

Use hook_form_alter to hook into the form and programmatically insert the captcha element or adjust the weight of the element or pur the element inside the fieldset.

function example_form_alter(&$form, &$form_state, $form_id) {
  if($form_id == 'YOUR_FORM_ID') {
    // 1. Put the captcha element inside the fieldset 

    // OR

    // 2. Associate the capthca element to the form 
    //$form['captcha'] = array(
    //'#type' => 'captcha',
    //'#captcha_type' => 'image_captcha/Image',
    //);

    // OR

    // 3. Adjust the #weight attribute in the form 
  }
}

If you need more details please let me have the $form variable in txt format.

Answer 3

If you are creating the form youself, you should be able to do something as simple as this:

$form['YOURFIELDSET']['captcha'] = array(
  '#type' => 'captcha',
  '#captcha_type' => 'captcha/Math',
);

where 'YOURFIELDSET' is the Submit Your Book fieldset. (Just don't have the Captcha automatically add it itself.)
