Short version: How do I access keyword arguments passed to a ZPT?
Have a look at "options" as access-point to keyword-arguments... Taken from the ZopeBook (http://www.zope.org/Documentation/Books/ZopeBook/2_6Edition/AdvZPT.stx): """The action script can do all kinds of things. It can validate input, handle errors, send email, or whatever it needs to do to "get the job done". Here's a sketch of how to validate input with a script: ## Script (Python) "action" ## if not context.validateData(request): # if there's a problem return the form page template # along with an error message return context.formTemplate(error_message='Invalid data') # otherwise return the thanks page return context.responseTemplate() This script validates the form input and returns the form template with an error message if there's a problem. The Script's context variable is equivalent to here in TALES. You can pass Page Templates extra information with keyword arguments. The keyword arguments are available to the template via the options built-in variable. So the form template in this example might include a section like this: <span tal:condition="options/error_message | nothing"> Error: <b tal:content="options/error_message"> Error message goes here. </b></span> This example shows how you can display an error message that is passed to the template via keyword arguments. Notice the use of | nothing to handle the case where no error_message argument has been passed to the template.""" HTH, -mj
