Deprecation: #98283 - PHP Constant TYPO3_mainDir¶
See forge#98283
Description¶
The PHP Constant TYPO3_mainDir
which is defined as typo3/
has been marked as deprecated.
Impact¶
Accessing the constant will stop working in TYPO3 v13. No deprecation warning is thrown, but the Extension Scanner will detect any usage in your installation.
Affected installations¶
TYPO3 installations with custom third-party extensions using the constant directly, which is highly unlikely.
Migration¶
It is recommended to use the BackendEntryPointResolver
class when needing
to direct to the TYPO3 Backend. All other common APIs such as the Backend Router already
calculate the path automatically anyway.
