Example: .. code-block:: php 'columns' => [ 'nullable_column' => [ 'title' => 'A nullable field', 'config' => [ 'nullable' => true, 'eval' => 'trim', ], ], ], Impact ====== It is now possible to define TCA fields as nullable by setting the :php:`nullable` option to :php:`true`. The database field should have the according :sql:`NULL` option set. .. index:: TCA, ext:backend
