Hello devs,

I just uploaded a patch that implements an API for the evaluation of fields in the backend. I also moved the standard evaluatin methods (trim, int, required etc.) into a separate sysext called "evaluations".

The API can be used to implement self defined methods for evaluatiing fields in the backend. For example if you want to check the fieldvalue for a ZIP code, or a special phone prefix or whatever.

You can define both sides of evaluatiing. The PHP side which is performed before the value is stored into the database and the JavaScript part which is executed when the field loses the focus.

There is an example extension available that shows the concrete implementation of own evaluation types.

Because this patch is a quite big change of the field handling inside the system, I would like to ask you if you can test the patch if everything works correct and if there are any side effects I did not recognized yet.

If you have any questions or suggestions, please post them here or in the bugtracker.

The bugreport, patches and extensions can be found at http://bugs.typo3.org/view.php?id=1639.

I want to say thank you to Sebastian who helped me a lot to make the patches core and pcg compatible. ;-)

Greets,

Thomas
