XForm Validations

crishanthan wrote

Hello,

I am using Orbeon XForms through Intalio. However I face several validation issues related to XForms.

I need to limit certain input fields to 10 characters. If the user exceeds this limit (10 characters), a message should be shown and "!" mark should be activated. If the input is within the correct limit, it should not show any error message.

How do we get about this problem?

Thanks in advance.

Regards
Crishantha

Hi Crishantha
I work with Intalio XForms as well. If I need to restrict input fields to a certain length, I set up a regular expression in my schema or use a xpath expression in my bind nodeset expression in the xform?

Hi Crichantha!

you can define your constraint within Intalio Form Designer, check the pics I'm attaching.

Set XPath constraint for your field, like "string-length(.) <= 10" (see underlined in red) and Constraint violation message, in the attached example it's "Please input less than 10 chars". User will see the alert once s/he hovers on exclamation sign, like in the atatched pic.

I do not know though, how to restrict user to input more than 10 chars, i/o allow-validate-alert. That might be even better, but I don't remember right now how to accomplish it in xForms.

Cheers,

Oleg

You'r welcome, Crishantha.

The pb you describe is quite common: whenever you define some restriction on a field the "!" sign appears when the field is (yet) empty. I suppose there should be a good practice solution, personally I would do something simple like:

<my XPath constraint> or ""

I've tested - should work.

Cheers
