Subject RE: server side validation using cocoon flow script
Date Fri, 30 Jun 2006 16:23:08 GMT
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
