function views_form in Views (for Drupal 7) 7.3

Same name and namespace in other branches

1. 8.3 views.module \views_form()
2. 6.3 views.module \views_form()

This is the entry function. Just gets the form for the current step.

The form is always assumed to be multistep, even if it has only one step (the default 'views_form_views_form' step). That way it is actually possible for modules to have a multistep form if they need to.

  $form_state['step'] = isset($form_state['step']) ? $form_state['step'] : 'views_form_views_form';

  // Cache the built form to prevent it from being rebuilt prior to validation
