# Deprecation: #104223 - Fluid standalone methods {#deprecation-104223-1721383576}

See [forge#104223](https://forge.typo3.org/issues/104223)

## Description {#description}

Some methods in Fluid standalone v2 have been marked as deprecated:

-   `\TYPO3Fluid\Fluid\Core\ViewHelper\AbstractTagBasedViewHelper->registerUniversalTagAttributes()`
-   `\TYPO3Fluid\Fluid\Core\ViewHelper\AbstractTagBasedViewHelper->registerTagAttribute()`

## Impact {#impact}

Calling these methods is discouraged. They will log a deprecation level
error when used with Fluid standalone v4.

## Affected installations {#affected-installations}

Instances with extensions calling above methods.

## Migration {#migration}

### registerUniversalTagAttributes() {#registeruniversaltagattributes}

Within tag based ViewHelpers, calls to `registerUniversalTagAttributes()` should be removed.
This method has been marked as `@deprecated` with Fluid standalone 2.12, will
log a deprecation level error with Fluid standalone v4, and will be removed with v5.

When removing the call, attributes registered by the call are now available in
`$this->additionalArguments`, and no longer in `$this->arguments`. This *may* need
adaption within single ViewHelpers, *if* they handle such attributes on their own. For example,
the common ViewHelper `f:image` was affected within the TYPO3 Core. The following attributes
may need attention when removing `registerUniversalTagAttributes()`: `class`, `dir`,
`id`, `lang`, `style`, `title`, `accesskey`, `tabindex`,
`onclick`.

### registerTagAttribute() {#registertagattribute}

Within tag based ViewHelpers, calls to `registerTagAttribute()` should be removed.
This method has been marked as `@deprecated` with Fluid standalone 2.12, will
log a deprecation level error with Fluid standalone v4, and will be removed with v5.

The call be often simply removed since arbitrary attributes not specifically registered
are just added as-is by `\TYPO3Fluid\Fluid\Core\ViewHelper\AbstractTagBasedViewHelper`.
This only needs attention
if single view helpers deal with such attributes within the `render()` method:
When removing the call, those arguments are no longer available in `$this->arguments`,
but in `$this->additionalArguments`. Additional attention is needed with
attributes registered with type `boolean`: Those usually have some handling
within `render()`. To stay compatible, it can be helpful to not simply
remove the `registerTagAttribute()` call, but to turn it into a call to
`registerArgument()`.
