function current_search_check_visibility in Facet API 7

Same name and namespace in other branches

1. 6.3 contrib/current_search/current_search.block.inc \current_search_check_visibility()
2. 7.2 contrib/current_search/current_search.block.inc \current_search_check_visibility()

Checks whether the block should be displayed.

In cases where modules like Context are being used, hook_block_list_alter() is not invoked and we get fatal errors. We have to test whether or not the hook has been invoked and call this function manually otherwise.

Parameters

$delta: The block delta.

Return value

A boolean flagging whether to display this block or not.

1 call to current_search_check_visibility()
