Hello,
I have the following problem: In XML I have an element "image" with two attributes @src and @alt. If @src is filled in the CMS form, then @alt becomes a required field. Looking at http://www.hippocms.org/display/CMS/Template+validation I would say that this can be implemented with a bit of JavaScript (flowscript). Section "More about javascript (flowscript) validation" suggests there is a function lookupWidget( widget, xpath ) that according to the description: "Returns a widget object, relative to the widget passed as first argument, using the relative/absolute xpath to that widget." So I expected the following piece of code to work: <rule for="/document/content/paragraphs/paragraph/image"> <validation> <validator name="javascript"> <![CDATA[ var srcWidget = lookupWidget(widget,"@src"); var altWidget = lookupWidget(widget,"@alt"); if ((srcWidget != null)){ if (srcWidget.value != null && (widget.value == null || widget.value.length() <= 0)){ setValidationError(widget,"Alt is required field."); return false; } } clearValidationError(widget); // clear previous validation errors return true; ]]> </validator> </validation> </rule> It doesn't. Tried all sorts of variations: "./@xxx" paths, rule on @alt with ../@src path, etc. In the end I tried something that doesn't use lookupWidget at all: <rule for="/document/content/paragraphs/paragraph/image/@alt"> <validation> <validator name="javascript"> <![CDATA[ if ((widget.value == null || widget.value.length() <= 0)){ setValidationError(widget,"Alt is required field."); return false; } clearValidationError(widget); // clear previous validation errors return true; ]]> </validator> </validation> </rule> This doesn't work either. Can anyone explain what I am doing wrong or where I can find more information to solve this? Thanks, Reinier -- Reinier van den Born HintTech B.V.
