Support regex validation

[dmolineus]

As for example the email validation differes between Contao and form validation there should be an option to support at least custom regex validators.

Does the extension have the possibility for validators e.g. 'between' or 'greaterThan'?

Now I can check if a textfield is empty or not. Thats not very much functionality, I would need the validators which are supported by formvalidation.io

If it's not possible out of the box, would there be a way to add the validators manually?

Thank you very much.

The feature to support advanced validators is not added yet. Even though the technical base is prepared for it. You could use the BuildValidationFieldEvent https://github.com/netzmacht/contao-form-validation/blob/master/src/Event/BuildValidationFieldEvent.php to provide custom validators and the Contao hooks in the backend.

The concept included to configure such validators in the backend. I doubt that I'll add it on my own. The formvalidation library seems to be dead. No updates since 2015 and the domain is not available right now.
