Impact ====== Extensions registering the any one of the hooks listed above will trigger a PHP :php:`E_USER_DEPRECATED` error when the code is executed. Affected Installations ====================== TYPO3 installations with older extensions implementing one of the hooks above, which is very rare and only serve specific use-cases for rendering ContentObjects or custom link style tags that are not related to TYPO3 v8 linking syntax (`t3://...`). Migration ========= The hooks :php:`cObjTypeAndClass` and :php:`cObjTypeAndClassDefault` can be simplified by using the new way of registering custom ContentObjects via: :php:`$GLOBALS['TYPO3_CONF_VARS']['FE']['ContentObjects']` - see :file:`EXT:frontend/ext_localconf.php` for examples - TYPO3 Core adds its shipped ContentObjects exactly the same way. The :php:`typolinkLinkHandler` hook is used for registering custom link syntax that start with a certain keyword such as "news:13". Since TYPO3 v8, LinkHandler support has been added to TYPO3 Core natively, using the new `t3://` syntax. The "LinkHandler" registry can be extended via :php:`$GLOBALS['TYPO3_CONF_VARS']['SYS']['linkHandler']` and :php:`$GLOBALS['TYPO3_CONF_VARS']['FE']['typolinkBuilder']` that serves the same purpose with a better API. .. index:: Frontend, FullyScanned, ext:frontend
