Breaking: #97201 - Removed hook for new content element wizard

See Issue #97201

Description

The hook $GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['cms']['db_new_content_el']['wizardItemsHook'] has been removed in favor of a new PSR-14 Event \TYPO3\CMS\Backend\Controller\Event\ModifyNewContentElementWizardItemsEvent.

Additionally, the params property of a wizard item has been removed, since it just duplicated the default values, configured with tt_content_defValues and therefore previously required extension authors to provide the same information twice in two different formats.

Note

The public methods getPageInfo(), getColPos(), getSysLanguage() and getUidPid() have been removed from the internal NewContentElementController class, since they were only added for the use in the now removed hook. Those information are now directly available in the new PSR-14 Event.

Impact

Any hook implementation registered is not executed anymore in TYPO3 v12.0+.

The params property on a wizard item is no longer evaluated.

Affected Installations

TYPO3 installations with custom extensions using this hook.

TYPO3 installations setting the params property on a wizard item.

Migration

The hook is removed without deprecation in order to allow extensions to work with TYPO3 v11 (using the hook) and v12+ (using the new Event) when implementing the Event as well without any further deprecations.

Use the PSR-14 Event to allow greater influence in the functionality.

Migrate the params property to tt_content_defValues or just remove params in case the information had already been configured for both properties.
