.. include:: /Includes.rst.txt .. _deprecation-86279: ========================================================== Deprecation: #86279 - Various Hooks and PSR-15 Middlewares ========================================================== See :issue:`86279` Description =========== The new PSR-15-based middleware concept allows for a more fine-grained "hooking" mechanism when enhancing the HTTP Request or Response object. The following hooks have therefore been marked as deprecated: * :php:`$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['tslib/class.tslib_fe.php']['tslib_fe-PostProc']` * :php:`$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['tslib/class.tslib_fe.php']['connectToDB']` * :php:`$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['tslib/class.tslib_fe.php']['initFEuser']` * :php:`$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['tslib/class.tslib_fe.php']['checkDataSubmission']` * :php:`$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['tslib/index_ts.php']['preBeUser']` * :php:`$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['tslib/index_ts.php']['postBeUser']` * :php:`$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['tslib/class.tslib_fe.php']['checkAlternativeIdMethods-PostProc']` * :php:`$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['tslib/index_ts.php']['preprocessRequest']` On top, some middlewares have only been introduced in order to execute these hooks, or due to, and are marked for internal use: * :file:`typo3/cms-core/normalized-params-attribute` * :file:`typo3/cms-backend/legacy-document-template` * :file:`typo3/cms-backend/output-compression` * :file:`typo3/cms-backend/response-headers` * :file:`typo3/cms-frontend/timetracker` * :file:`typo3/cms-frontend/preprocessing` * :file:`typo3/cms-frontend/eid` * :file:`typo3/cms-frontend/content-length-headers` * :file:`typo3/cms-frontend/tsfe` * :file:`typo3/cms-frontend/output-compression` * :file:`typo3/cms-frontend/prepare-tsfe-rendering` * :file:`typo3/cms-frontend/shortcut-and-mountpoint-redirect` As these middlewares are marked as internal, it is recommended not to reference them directly, as these might get removed in TYPO3 v10. Impact ====== Making use of one of the hooks in an extension will trigger a PHP :php:`E_USER_DEPRECATED` error. Affected Installations ====================== TYPO3 instances with extensions using any of the hooks. Migration ========= Use a custom PSR-15 middleware instead. .. index:: PHP-API, FullyScanned, ext:frontend
