function hook_filter_harmonizer_is_empty in Views Filter Harmonizer 1.0.x
Same name and namespace in other branches
- 8 filter_harmonizer.api.php \hook_filter_harmonizer_is_empty()
Allow modules to alter the meaning of 'is empty' for regular filter values.
By default filter $value is considered empty when: -- it is an empty array, or -- when all of the array elements -- equal NULL or the empty string '' or an empty array, or -- are arrays with elements that equal NULL or '' or an empty array.
Other modules may override this rule of thumb by implementing this hook. Function does not return a value, but your hook implementation must set the variable $is_empty.
Parameters
bool $is_empty: Set this according to whether the $filter is considered empty or not.
Drupal\views\Plugin\views\filter\FilterPluginBase $filter: The associated Views exposed filter handler, if needed.
