function node_mass_update

Updates all nodes in the passed-in array with the passed-in field values.

IMPORTANT NOTE: This function is intended to work when called from a form submission handler. Calling it outside of the form submission process may not work correctly.

Parameters

array $nodes: Array of node nids or nodes to update.

array $updates: Array of key/value pairs with node field names and the value to update that field to.

string $langcode: (optional) The language updates should be applied to. If none is specified all available languages are processed.

bool $load: (optional) TRUE if $nodes contains an array of node IDs to be loaded, FALSE if it contains fully loaded nodes. Defaults to FALSE.
