1 config.sync.inc config_sync_validate_file($config_name, $config_change_type, $all_changes = NULL, $config_data = NULL)

Validate an individual configuration to ensure it's safe to import.

Calls all the necessary hooks to allow modules to validate a set of configuration changes. If any module encounters a validation problem, it should throw a ConfigValidateException exception.


string $config_name: The name of the config file being synced.

string $config_change_type: The type of change occurring to this config file. Must be one of the following values: "create", "update", or "delete".

array|NULL $all_changes: If this file is being changed with a group of other configuration files, pass in the complete set of files that are anticipated to be changed during the sync. If doing a typical sync between staging and live directories, this value can be retrieved from config_get_statuses(). If syncing a single configuration file, this value should be NULL.

array $data: The configuration data to be validated if the data is coming from a source other than the staging configuration storage.
