server side validation using cocoon flow script
Hi,
I'm using cocoon 2.1.8. I am using HTML form inside my XSL's. ( I could
have used CForms, but at this moment it will be a bigger change for me, as
I have to change at many places. Too late to make this change. ).
What I need :
In this case i'm accessing request parameters from the form inside flow
script function. If any of them is empty i have to send it back pre-filled
with other choices that user has entered.
Ex.
If a form has 5 input fields, and user enters only first two then i have
to show a error message alongwith already pre-filled choices 1 and 2
Here I'm able to validate and display the error message, but I can't show
the page with pre-filled choices.
Is there any way for doing this?
Any inputs and suggestions are welcome.
Thanks in advance,
Rahul

Hi Rahul
I suppose you can do something like this:-
1. Have all the values of the fields as request parameters.
2. As you submit check the request parameters values at the xsl before
populating the fields in the form.
3. If its empty then go for a call template where the javascript function
currently being used does the validation else populate the values
in the fields of the form.

Arnab

Check out JXTemplateTransformer. Here's the doc for the
generator-implementation, but the transformer works the same way.
You can then put in your HTML something like: <input name="firstname"
type="text"
value="${cocoon.request.firstname}"/>
and run this document through JXTemplateTransformer. the fields will then
populate with the data user has provided.

Pass the request parameters to your XSL and insert these as the
'initial' value of the input fields. You need a few steps to achieve
this:
- either call the xsl with:
<map:transform src="mytemplate.xsl">
<map:parameter name="use-request-parameters" value="true" />
</map:transform>
or pass each request-param as a separate parameter to the XSL call.
- define an <xsl:param name="my_request_param" /> for each of the
request parameters in your XSL
- define the input fields in your XSL like for instance: <input
type="text" value="{$my_request_param}" />
The request-parameters should boil through from initial request to the
pipeline called with sendPage(AndWait)..
Kind regards,
Geert
