My requirement:
Perform business level validation to ensure the entered data are valid before notifying the user that
their form request is accepted and refreshing the web page with acceptance message.
[business level: requires access to external database for checking valid values.]
Pre 2.1.5 solution:
Define a javascript function, a part of the flow script, to do business validation processing and associate this function with the form using:
A. "I used fd:javascript though where only external validation functions are called. So I determine how a field has to be validated in the form definition, but the validation itself is scripted in external js files." http://marc.theaimsgroup.com/?l=xml-cocoon-users&m=108639582110249&w=2
Joerg, can you give more details! Is it possible to access flow variables from your external js file?
I have a file validate.js that has some validateXYZ() functions in it. validate.js is added to the sitemap like any other flowscript js file. In the form definition I have:
<fd:field>
<fd:validation>
<fd:javascript>
return validateXYZ(widget);
</fd:javascript>
</fd:validation>
</fd:field>B. "On each widget, you can add validators using the Widget.addValidator(...) method. The argument is an implementation of WidgetValidator. See the javadoc of that interface for more details on what an implementation of a WidgetValidator is supposed to do." http://marc.theaimsgroup.com/?l=xml-cocoon-dev&m=108401608717385&w=2
This seems to be for individual widget level validation support. How can this be used for the form level validation? A sample code will be very helpful.
Bruno explained some more details here: http://marc.theaimsgroup.com/?l=xml-cocoon-users&m=108555680116244&w=4.
