function chado_get_id_from_nid

2.x chado_get_id_from_nid($table, $nid, $linking_table = NULL)

Get chado id for a node. E.g, if you want to get 'analysis_id' from the 'analysis' table for a synced 'chado_analysis' node, (the same for organisms and features): $analysis_id = chado_get_id_from_nid ('analysis', $node->nid) $organism_id = chado_get_id_from_nid ('organism', $node->nid) $feature_id = chado_get_id_from_nid ('feature', $node->nid)


$table: The chado table the chado record is from

$nid: The value of the primary key of node

$linking_table: The Drupal table linking the chado record to it's node. This field is optional and defaults to chado_$table

Return value
