New Feature: Custom validation rules

Hi Russ

Yes, the validation is for single field only. Maybe we in the parameter of my_custom_rule method, we can give access to other variables

- $fields: Array of fields use on the form
- $data: Array of field value

Base on that, you can perform the custom validation rule yourself? And instead of return false when not valid, you can return array of error messages? Will that work?

Tuan

Hi Tuan,
from my perspective it's just important to have access to the field contents, it's just that validating one field may require data from several fields. Sounds good.
Russ.

Hi Russ

Forgot to update that you can access to all form data in the custom validation rule, you can see it at eventbookingdoc.joomservices.com/basic-s...ld-custom-validators

Tuan

For those Italians out there please find attached the validator php file that checks the "Codice Fiscale" (tax id number). Tested and working.

The php original function was freely available on the net, I just customized it to work with events booking.

Tuan again thanks!!

Andrea.

Hi Andrea

I am sorry, I decided to use a new validation library for the extension in the next release 3.5.2, so the code for custom validation rule will have to be changed a bit. See eventbookingdoc.joomservices.com/basic-s...ld-custom-validators

So before updating to version 3.5.2, please adjust your custom rules you built for your site

Sorry for the inconvenience (the old library is very big and contains many unnecessary code), so I decided to switch to a lighter library for easier maintainance

Regards,

Tuan

Hi Tuan, this is not too nice as poor people like me who don't know php very well (indeed not at all) spent the last night to create two new validation rules, which I have now to re-write.

Hopefully, the necessary modification won't be too complex to apply even for a php-ignorant like me, so at the end it's OK and I'll do it.

Don't change it another time !

Regards

Only this time. And actually, it's not really re-write. Just paste your original code to new method syntax and it will be fine

Tuan

Hello Tuan, no issues.

Indeed, I have already changed my rules to the new format and tested them in the dev system. They're working fine, so I'm moving them into production.

It took me just a bunch a minutes.

Thanks!

Andrea

Great. Happy to hear that
