function domain_get_node_domains in Domain Access 7.2

Same name and namespace in other branches

1. 6.2 domain.module \domain_get_node_domains()
2. 7.3 domain.module \domain_get_node_domains()

Parameters

$nodes: An array of nodes, keyed by node id, or a single node id.

$reset: A boolean flag indicating the need to reset the static variable for the node.

Return value

An array of data, keyed by node id, or a single array for a single node. The data array, consists of two parts. 'domain_id' is an array of active domain ids. 'domain_site' is a TRUE/FALSE boolean indicating affiliate status.
