# Importing data to other tables¶

This extension does not directly provide a mechanism for mapping LDAP data to other tables than those related to groups and users. However it is possible to make it so that some data is not mapped to the users table but passed instead to a hook, enabling a separate extension to handle that data.

Defining such data is easy. With the usual mapping syntax:

local_field = ldap_field


Any local_field that does not exist in the mapped users table will be considered “extra data”. The local_field may have any special syntax that suits your needs (for example “table__field”) as long as it does not mess with the mapping configuration itself.

Warning

In previous versions of this extension (2.x) it was possible to use a dot for local_field (e.g., table.field).

This is not supported anymore since you may use TypoScript to post-process the mapping. We suggest that you use a double underscore character instead (__) as in table__field.

All fields considered to be extra data will be mapped to LDAP values as any other field, but stored separately and passed to the hook.

In your extension (in the ext_localconf.php file), register the hook using a code like:

$GLOBALS['TYPO3_CONF_VARS']['EXTCONF']['ig_ldap_sso_auth']['extraDataProcessing'][] = 'EXT:extension/Path/To/Class/ClassName.php:VendorName\\ClassName';  Your class has to implement the \Causal\IgLdapSsoAuth\Utility\ExtraDataProcessorInterface interface. This implies implementing a method called processExtraData which will receive the following arguments:$userTable
The name of the user table that was just handled (should normally be “fe_users” or “be_users”).
$user Full user record plus the extra data to handle in your extension. The extra data is located in $user['__extraData']. It is up to your extension to handle it as needed.

Note

This process exists only for users, not for groups.
