Class

views_handler_filter_string

Basic textfield filter to handle string filtering commands including equality, like, not like, etc.

Code

function value_form(&$form, &$form_state) {
  // We have to make some choices when creating this as an exposed
  // filter form. For example, if the operator is locked and thus
  // not rendered, we can't render dependencies; instead we only
  // render the form items we need.
  $which = 'all';
