function taxonomy_select_nodes

taxonomy_select_nodes($tid, $pager = TRUE, $limit = FALSE, $order = array('t.sticky' => 'DESC', 't.created' => 'DESC'))

Return nodes attached to a term across all field instances.

This function requires taxonomy module to be maintaining its own tables, and will return an empty array if it is not. If using other field storage methods alternatives methods for listing terms will need to be used.

Parameters

$tid: The term ID.

$pager: Boolean to indicate whether a pager should be used.

$limit: Integer. The maximum number of nodes to find. Set to FALSE for no limit.

$order: An array of fields and directions.

Return value

An array of nids matching the query.
