# Deprecation: #97384 - TCA option "eval=null" replaced with "nullable" {#deprecation-97384}

See [forge#97384](https://forge.typo3.org/issues/97384)

## Description {#description}

The TCA option `eval=null` has been replaced with the boolean option
`nullable`.

## Impact {#impact}

The TCA option `eval=null` will be automatically migrated to
`'nullable' => true`. The migration will trigger a PHP `E_USER_DEPRECATED` error.

## Affected Installations {#affected-installations}

All installations defining the `null` value in their `eval` list.

## Migration {#migration}

To migrate your TCA add the TCA option `'nullable' => true` and remove the
`null` value from the field's `eval` list.

```php
// Before

'columns' => [
   'nullable_column' => [
       'title' => 'A nullable field',
       'config' => [
           'eval' => 'null',
       ],
   ],
],

// After

'columns' => [
   'nullable_column' => [
       'title' => 'A nullable field',
       'config' => [
           'nullable' => true,
       ],
   ],
],
```
