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

See forge#97201


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.


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.


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).

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.
