I need some help. I have a multi-page form which is defined similarly to the
multipage sample. The form is a self-registration form. The user's e-mail
address is used as their user-id. The first page contains a field "email".
The page needs to validate that the email address hasn't already been
registered in the system. I want to keep the validation code separate from
the form because, in the near future, the validation process will change to
using an LDAP.
I have been able to get javascript code to execute in a validation block in
the first page's <fd:struct>, but I don't know how to provide a bean or
anything to that validation code. I've tried just passing a string from the
flow script, but it seems I can't work with it in the model section. Here's
a snippet of the flow, followed by a snipped of the model. If anyone can
help, I'd be grateful.
If I understand your problem correctly, you should be able to use a
javascript validator on the email widget, something like:
<fd:field id="email" required="true">
<fd:label>E-mail:</fd:label>
<fd:datatype base="string" />
<fd:validation>
<fd:email/>
<fd:javascript>
var isValid = validateEmailAddress(widget.getValue());
if(!isValid) {
widget.setValidationError(
new Packages.org.apache.cocoon.forms.
validation.ValidationError("Address already used.")
);
}
return isValid;
</fd:javascript>
</fd:validation>
</fd:field>
...where validateEmailAddress() is a function defined externally that
performs the validation (whether it's LDAP or whatever) and returns true
or false. You can also call out to a Java method for that validation if
that's how it's implemented.
