Deprecation: #88854 - T3_THIS_LOCATION

See Issue #88854


The global JavaScript variable T3_THIS_LOCATION containing the URL to the current document (if not modified) has been marked as deprecated.


Since this is a global JavaScript variable, no proper deprecation layer applies and thus no deprecation notice is rendered.

Some PHP API uses T3_THIS_LOCATION (e.g. BackendUtility::getLinkToDataHandlerAction() with second argument being -1 ) has been marked as deprecated as well.

Affected Installations

All third party extensions using T3_THIS_LOCATION are affected.


When generating URLs containing a returnUrl (a common use-case for T3_THIS_LOCATION ), consider using either rawurldecode(GeneralUtility::getIndpEnv('REQUEST_URI')) or normalizedParams in the PSR-7 ServerRequest object: $request->getAttribute('normalizedParams')->getRequestUri() .

In general, onclick handlers doing a redirect are considered bad practice. Use HTML’s href attribute and attach custom click handlers, if necessary.
