function ctools_process_form in Chaos Tool Suite (ctools) 6

ctools' replacement for drupal_process_form that accepts commands not to redirect, as well as forcing processing of 'get' method forms.

1 call to ctools_process_form()

ctools_build_form in includes/form.inc

Build a form, similar to drupal_get_form(). However, arguments to the form builder are not sent through. Instead, the $form_state can be given all the necessary data to fully utilize the form.

CTools' replacements for Drupal's form functions.
