Deprecation: #86389 - GeneralUtility::_GETset() and TSFE->mergingWithGetVars()¶
Two methods related to setting global
$_GET parameters have been marked as deprecated:
The two methods are wrappers to set the
$_GET properties, however, this concept has been superseded
by using the PSR-7 request object within PSR-15 middlewares to replace the variables.
Calling any of the two methods within PHP will trigger a PHP
Any installation making use of these methods within a TYPO3 extension, e.g. RealURL.
Implement a custom PSR-15 middleware to update the PSR-7 request object, and to manually set
$_GET on top,
as long as TYPO3 still supports
GeneralUtility::_GP(), although these methods will vanish in the near future.
Relying on the request object, and using PSR-15 middlewares to manipulate request parameters is more future-proof for extensions and TYPO3 sites.
