==========================================================
Deprecation: #107648 - InfoboxViewHelper STATE_* constants
==========================================================

See :issue:`107648`

Description
===========

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

* :php:`InfoboxViewHelper::STATE_NOTICE`
* :php:`InfoboxViewHelper::STATE_INFO`
* :php:`InfoboxViewHelper::STATE_OK`
* :php:`InfoboxViewHelper::STATE_WARNING`
* :php:`InfoboxViewHelper::STATE_ERROR`

These constants have been superseded by the dedicated enum
:php:`\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 :php:`STATE_*` constants from
:php-short:`\TYPO3\CMS\Fluid\ViewHelpers\Be\InfoboxViewHelper` in their PHP
code or Fluid templates.

Migration
=========

Replace the deprecated constants with the corresponding
:php-short:`\TYPO3\CMS\Core\Type\ContextualFeedbackSeverity` enum.

..  important::
    Whenever possible, use the enum directly instead of extracting its
    integer value. This provides better type safety and makes the code
    more expressive. Only use :php:`->value` when you explicitly need
    the integer representation.

..  code-block:: php
    :caption: Example (PHP)

    // 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 :html:`f:constant()`:

..  code-block:: html
    :caption: Example (Fluid Template)

    <!-- 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 :php-short:`\TYPO3\CMS\Fluid\ViewHelpers\Be\InfoboxViewHelper` has been
updated to accept both the enum directly and integer values for backward
compatibility.
