Feature: #61489 - Allow own TypoScript Conditions in Backend as well

See Issue #61489

Description

It is now possible to add own TypoScript conditions via a separate API in the Backend. The API for the frontend was introduced with TYPO3 CMS 7.0.

An extension/package can now ship an implementation of a new abstract class AbstractCondition. Via the existing TypoScript Condition Syntax the class is called by the simple fully namespaced class name. The class’ main function “matchCondition” can flexibly evaluate any parameters given after the class name.

Usage:

[BigCompanyName\TypoScriptLovePackage\MyCustomTypoScriptCondition]

[BigCompanyName\TypoScriptLovePackage\MyCustomTypoScriptCondition = 7]

[BigCompanyName\TypoScriptLovePackage\MyCustomTypoScriptCondition = 7, != 6]

[BigCompanyName\TypoScriptLovePackage\MyCustomTypoScriptCondition = {$mysite.myconstant}]

where the TypoScript Condition class deals with =/!= etc itself.

Impact

If you’ve previously used the userFunc condition, you are encouraged to use this new API for your own TypoScript conditions.
