Deprecation: #90937 - Various hooks in ContentObjectRenderer¶
See forge#90937
Description¶
The following hooks within class ContentObjectRenderer
have been marked as deprecated:
$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['tslib/class.tslib_content.php']['cObjTypeAndClass']
$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['tslib/class.tslib_content.php']['cObjTypeAndClassDefault']
$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['tslib/class.tslib_content.php']['extLinkATagParamsHandler']
$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS']['tslib/class.tslib_content.php']['typolinkLinkHandler']
All hooks have been available for a long time, and several new concepts and APIs that have been added in previous LTS versions already, that superseded these hooks.
Impact¶
Extensions registering the any one of the hooks listed above will trigger a 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 cObjTypeAndClass
and cObjTypeAndClassDefault
can be simplified by using the new way of registering custom ContentObjects via:
$GLOBALS['TYPO3_CONF_VARS']['FE']['ContentObjects']
- see EXT:frontend/ext_localconf.php
for examples - TYPO3 Core adds its shipped ContentObjects exactly the same way.
The 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 $GLOBALS['TYPO3_CONF_VARS']['SYS']['linkHandler']
and $GLOBALS['TYPO3_CONF_VARS']['FE']['typolinkBuilder']
that serves the same purpose with a better API.
