# Feature: #102077 - Allow custom default value in getFormValue() conditions function {#feature-102077-1696240251}

See [forge#102077](https://forge.typo3.org/issues/102077)

## Description {#description}

The `getFormValue()` function can be used in conditions of form variants to
safely retrieve form values. Before, `null` was returned as default value. This
made it impossible to use this, for example, with the `in` operator to check
values in multi-value form fields. An additional check was necessary to avoid
type issues:

```yaml
variants:
  - identifier: variant-1
    condition: 'getFormValue("multiCheckbox") && "foo" in getFormValue("multiCheckbox")'
```

A second argument has been added to this function to set a custom default value.
This allows shortening conditions accordingly:

```yaml
variants:
  - identifier: variant-1
    condition: '"foo" in getFormValue("multiCheckbox", [])'
```

## Impact {#impact}

Form variant conditions can be shortened.
