Deprecation: #107648 - InfoboxViewHelper STATE_* constants 

Description 

The public constants in \TYPO3\CMS\Fluid\ViewHelpers\Be\InfoboxViewHelper for defining the state/severity of an infobox have been deprecated:

• \TYPO3\CMS\Fluid\ViewHelpers\Be\InfoboxViewHelper::STATE_NOTICE
• \TYPO3\CMS\Fluid\ViewHelpers\Be\InfoboxViewHelper::STATE_INFO
• \TYPO3\CMS\Fluid\ViewHelpers\Be\InfoboxViewHelper::STATE_OK
• \TYPO3\CMS\Fluid\ViewHelpers\Be\InfoboxViewHelper::STATE_WARNING
• \TYPO3\CMS\Fluid\ViewHelpers\Be\InfoboxViewHelper::STATE_ERROR

These constants have been superseded by the dedicated enum \TYPO3\CMS\Core\Type\ContextualFeedbackSeverity , which provides a single source of truth for severity levels across the entire TYPO3 Core and improves type safety and maintainability.

Impact 

Using these constants will trigger a PHP deprecation warning. The constants will be removed in TYPO3 v15.0. The extension scanner will report usages as weak match.

Affected installations 

Instances using any of the STATE_* constants from InfoboxViewHelper in their code or Fluid templates.

Migration 

Replace the deprecated constants with the corresponding ContextualFeedbackSeverity enum.

// Before
use TYPO3\CMS\Fluid\ViewHelpers\Be\InfoboxViewHelper;
$state = InfoboxViewHelper::STATE_ERROR;

// After - Recommended: Use the enum directly
use TYPO3\CMS\Core\Type\ContextualFeedbackSeverity;
$severity = ContextualFeedbackSeverity::ERROR;

// Alternative: Use the integer value when explicitly needed
$stateValue = ContextualFeedbackSeverity::ERROR->value;

In Fluid templates, use the enum via f:constant():

<!-- Before -->
<f:be.infobox title="Error!"
    state="{f:constant(name: 'TYPO3\CMS\Fluid\ViewHelpers\Be\InfoboxViewHelper::STATE_ERROR')}">
    Error message
</f:be.infobox>

<!-- After -->
<f:be.infobox title="Error!"
    state="{f:constant(name: 'TYPO3\CMS\Core\Type\ContextualFeedbackSeverity::ERROR')}">
    Error message
</f:be.infobox>

The InfoboxViewHelper has been updated to accept both the enum directly and integer values for backwards compatibility.
