Introduction¶

What does it do?¶

The PxValidation extension (px_validation) enables the possibility to define different validation configuration in your TypoScript for each Extbase-Controller-Action without touching the affected extension itself. This makes it easy to change the default validation behaviour of vendor extensions without changing their code. But the greatest benefit is that it opens the option to declare multiple variants of validation rules within one page tree. It is even possible to nest validation rules, so you can validate child objects.
