Same name and namespace in other branches

1. 6.3 webform.module \webform_check_record()
2. 7.4 webform.module \webform_check_record()

Utility function to check if a webform record is necessary in the database.

If the node is no longer using any webform settings, this function will delete the settings from the webform table. Note that this function will NOT delete rows from the webform table if the node-type is exclusively used for webforms (per the "webform_node_types_primary" variable).

Parameters

$node: The node object to check if a database entry is still required.

Return value

Returns TRUE if the webform still has a record in the database. Returns FALSE if the webform does not have a record or if the previously existing record was just deleted.

function webform_check_record(&$node) {
  $webform = $node->webform;
  $webform['record_exists'] = FALSE;
