function entityreference_autocreate_get_target_bundle in Entityreference Autocreate 7

Find the desired target entity type (bundle name).

Utility function. Abstracted as we need to know this often, and we also need to handle the basic vs views-based lookup each time.

Returns either an array (which usually indicates a config problem) or just the first element in that array.

Parameters

$field_info: The field info from the current context.

bool $multiple: If set, return an array of bundle names.

Return value

string|array|null The bundle name.
