Parameters

ColumnTypeDefaultDescription
$ref integer - resource id being updated
&$fields
&$all_selected_nodes
$locked_fields array - array of locked data columns (may also include resource table columns - handled by copy_locked_data)
$lastedited integer - last edited resource to copy data from
$save boolean false - save data to database (as opposed to just updating the $fields array e.g. for edit page)
$fields array - resource $fields array
$all_selected_nodes array - array of existing resource nodes

Return

void
