function global_filter_block_configure in Views Global Filter 8

Same name and namespace in other branches

2. 7 global_filter.blocks.inc \global_filter_block_configure()

Implements hook_block_configure().

Note that this hook cannot easily be used with dynamic forms adding additional fields at the press of a button, because form_state is not passed as its argument. See drupal.org/node/690828. Therefore the actions of adding or removing a fieldset (filter) is not easily communicated back to this function.
