function conditional_fields_states_handler_select_multiple in Conditional Fields 7.3

States handler for multiple select lists.

Multiple select fields always require an array as value. In addition, since our modified States API triggers a dependency only if all reference values of type Array are selected, a different selector must be added for each value of a set for OR, XOR and NOT evaluations.

Define dependencies between fields based on their states and values.

Code

function conditional_fields_states_handler_select_multiple($field, $field_info, $options, &$state) {
  switch ($options['values_set']) {
    case CONDITIONAL_FIELDS_DEPENDENCY_VALUES_WIDGET:
    case CONDITIONAL_FIELDS_DEPENDENCY_VALUES_AND:
      $state[$options['state']][$options['selector']]['value'] = (array) $state[$options['state']][$options['selector']]['value'];
      return;
    case CONDITIONAL_FIELDS_DEPENDENCY_VALUES_XOR:
      $select_states[$options['state']][] = 'xor';
    case CONDITIONAL_FIELDS_DEPENDENCY_VALUES_REGEX:
      $regex = TRUE;
    case CONDITIONAL_FIELDS_DEPENDENCY_VALUES_NOT:
    case CONDITIONAL_FIELDS_DEPENDENCY_VALUES_OR:
      foreach ($options['values'] as $value) {
        $select_states[$options['state']][] = array(
          $options['selector'] => array(
            $options['condition'] => empty($regex) ? array(
              $value,
            ) : $options['value'],
          ),
        );
      }
      break;
