Re: Numerical Field validation in Prettytracker to execute R code
Hi Moisés:
I would suggest that you try the validation feature, already implemented in Tracker fields:
https://doc.tiki.org/Tracker+Field+Validation
You can create your own validation methods, it seems, as documented there, or use the regexp validation type, so that you can use your own regular expression there, without creating any new php file, etc.
Unfortunately, I'm not that good at regular expressions, but I bet that it's the besst approach for waht you want to achieve.
If you want to share some examples for your case, once you know how to do it, you can update this page:
Cheers
