validation

Hi,
There was a question I had I forgot to ask at the party today. I am trying to build a community site where multiple users from different regions will post content. There are two fields in which I would like to limit the values they can enter: Location and type.

I'm new to Drupal. I'm hoping to use it to build a workflow management application wherein privileged users can define perhaps a dozen forms to collect data from a large, distributed group of users. Each of these forms will experience some edits, changes of state, etc as they get processed by the workflow.

Can anyone tell me how this might work in drupal? Obviously I'll need the worfklow module installed. I've seen a 'form builder' module but it has a big warning about not being suitable for a production environment:

Hi folks. Can anyone give me any advice on CCK field validation?

The CCK Validation module apparently seems to do what I need but is only available for Drupal 5 (I'm developing in Drupal 6). All I need to do is check if some user entered text contains a certain string and display a custom error message in place if that condition isn't met.

Sorry if it's a bit of a noob question.

Cheers.

As a separate discussion from number validation, I've attached a short bit about AAA for text services. It's a PDF as it was a bit long to cut & paste into a posting, and it's not finished but I don't really want to make it much longer as it's already sleep-inducing ;-)

Hi,

Just started with this awesome module!

I am trying to create a rule where 'form element fieldname value check' needs to look at the field, and do something only if it is a null value. Entering 'null' in the value text area does not do the job. Leaving it blank is not possible as it is a mandatory field. How do I do this with rules, without hacking the other module that is creating the form?

Thanks
Srini

P.S.

I'm working on a Drupal 6 site that includes the ability to book resources (meeting rooms, projectors, etc). When somebody submits a new reservation/booking, I need to validate the reserved time to make sure it doesn't fall outside of business hours. I was hoping to do this with the Rules module, as I'd like the ability to change the validation criteria via the Drupal web UI.

This afternoon TapocoL, cYu and I (Kaaskop @ IRC) discussed the possibilities of CCK, Validation API and Fapilicious to work together on form processing. Currently, CCK features built-in validation for specific fields, like addresses. Fapilicious is a library which (though still under development) features built-in field validation for any form field. Validation API mainly is a UI for creating custom validators and using them for CCK fields.

A few of the ideas:
