Hi all
I've done a deal of searching through the archives, looked at the examples -
even read the docs - I'm still stuggling with this...
I need to validate a number of fields in a from; certain fields are required
if a checkbox is checked and should be empty if the checkbox is not checked.
What is the correct syntax in validator.xml?
'date_Shipped' must only be populated if the 'complete' checkbox is checked.
As an example of what I have tried....broken...
<field property="date_Shipped" depends="validwhen">
<arg0 key="returns.date_Shipped"/>
<var>
<var-name>test</var-name>
<var-value>(complete == 'on')</var-value>
</var>
</field>
That says date_Shipped is valid *only* when complete has the value 'on'.
And since a checkbox field is never going to have the value 'on',
date_Shipped isn't ever going to be valid...
What you want is probably something like
(((complete == false) and (*this* == null)) or
((complete == true) and (*this* != null)))
I'm not sure if true/false is what you need, or if that needs to be a
test for null; it probably depends on the type you've declared for the
'complete' property in your form.
