Captcha and flexinode

Flexinode is being replaced by CCK, hence I'd rather code for it.

It is very easy to fix this, just by adding one line of code to the captcha module:

Simply replace:

  foreach($user->roles as $role) {
    $candidate_trigger = $formid .'_'. strtr($role,' ','_') .'_captcha';

with:

  $formname = substr($formid,0,9) == "flexinode" ? "node_form" : $formid;
  foreach($user->roles as $role) {
    $candidate_trigger = $formname .'_'. strtr($role,' ','_') .'_captcha';
