Process form callback for BOTCHA form. Using hooking mechanism that is a hack - we want to come in before #process, but our _form_alter() is way too early (we want to let it use cache for all other modules & data). Ideal would be to have #process callback work on the form, but FAPI does not call it on forms, despite the documentation stating that it does. In fact, D6 code needs '#input'=TRUE on the element to get into calling #process callbacks. So we set '#input'=>TRUE on the form when inserting our callback into form['#process'], and it forces the FAPI to call that code path and we get our intercept. Works like a charm!

Code

function botcha_fprocess($element, &$form_state) {

  // UNUSED
  //  // Prevent caching of the page with BOTCHA elements.
  //  // This needs to be done even if the BOTCHA will be ommitted later:
  //  // other untrusted users should not get a cached page.
  //  global $conf;
  //  $conf['cache'] = 0;
  //  // This temporarily disables cache (for this page request)
  //  // Pressflow in CACHE_EXTERNAL caching mode additionally requires to mark
  //  // this request as non-cacheable to bypass external caches (e.g., Varnish).
  //  if (function_exists('drupal_page_is_cacheable')) {
  //    drupal_set_header('Cache-Control', 'no-cache, must-revalidate, post-check=0, pre-check=0', FALSE);
  //  }
