Help with pwValidator.cfc (Custom password validation tag/cfc)

Asked by BongSoo in Cold Fusion Markup Language, ColdFusion Studio, WebApplications

Tags: , ,

I hope I can explain this adequately. Basically I am trying to incorporate a custom tag/cfc into my code. The snippets below show the base tag and a test page that it works fine on.

What I have is an included template for a registration form that incorporates that tag. On the page that it is included in, I want to run a <cfswitch> check of the structure that is returned from the cfc. The cfc variable/structure is called pwStatus, and has two keys, message and status.

I cannot figure out how to pass them on to the next stage. Its almost a 'chicken or the egg' scenario. I tried putting them into session variables, but then it retains the first attempt - subsequent attempts only show the first attempt. I need it to pass the new version each time. This is sort of urgent, so 500 points!!!Start Free Trial

This is just a snippet of the page that the above is included in, but you can get a glimpse of what I am trying to do. Basically the name of the form (passed by a hidden field) determines whether it is a user logging in (works fine) or a new user submitting a new registration form (see above). If the
