1 common.inc backdrop_get_schema_unprocessed($module, $table = NULL)

Returns the unprocessed and unaltered version of a module's schema.

Use this function only if you explicitly need the original specification of a schema, as it was defined in a module's hook_schema(). No additional default values will be set, hook_schema_alter() is not invoked and these unprocessed definitions won't be cached. To retrieve the schema after hook_schema_alter() has been invoked use backdrop_get_schema().

This function can be used to retrieve a schema specification in hook_schema(), so it allows you to derive your tables from existing specifications.

It is also used by backdrop_install_schema() and backdrop_uninstall_schema() to ensure that a module's tables are created exactly as specified without any changes introduced by a module that implements hook_schema_alter().


$module: The module to which the table belongs.

$table: The name of the table. If not given, the module's complete schema is returned.

Return value

array The schema for the requested table, without modification by other modules.
