type = 'passthrough'¶
You can use this to send values directly to the database fields without any automatic evaluation. But still the update gets logged and the history/undo function will work with such values.
Since there is no rendering mode for this field type it is specifically fitted for direct API usage with the DataHandler.
This field is found in a number of tables, for instance the "pages" table. It is used by the system extension "impexp" to store some information.
'tx_impexp_origuid' => [ 'config' => [ 'type' => 'passthrough' ], ],
