Attention

TYPO3 v9 has reached its end-of-life September 30th, 2021 and is not maintained by the community anymore. Looking for a stable version? Use the version switch on the top left.

You can order Extended Long Term Support (ELTS) here: TYPO3 ELTS.

Base Variants¶

In Site Handling base variants represent different bases for a web site depending on a specified condition. For example a "live" base URL might be https://example.org but on local machine it's https://example.localhost as a domain - that's when variants are used.

Base variants exist for languages, too. Currently these can only be defined through the respective *.yml file, there is no UI available yet.

Variants consist of two parts:

a base to use for this variant
a condition that decides when this variant shall be active

Conditions are based on Symfony Expression Language and allow flexible conditions. For example:

applicationContext == "Development"

would define a base variant to use in Development context.

A configured base variant for development context.¶

Hint

For those coming from earlier TYPO3 versions: With site handling, there is no need for sys_domain records anymore! :)

The following variables and functions are available in addition to the default Symfony functionality:

base: 'https://example.org/'
