Re: Creating a back button

texte = >Or you could just use the [referrer] command that's built into webcatalog...Okay ... let's get back to the original point:The *original* question asked if it's possible to create a Back button on the page that would re-populate a form on the previous page with the same values it had when you left it. Therefore, because the original question had the specific requirement of filling in the form fields again, referrer will NOT work ...Referrer will not work with method=post at all, and it will not work with method=get either ... unless you do a lot of extra work, including putting the correct webdna into the form page that makes each field accept the form variables 'passed into' the page.Basically you have to create a form that makes sure NOTHING gets filled in when coming from the previous page, and yet it fills in all the appropriate field values when coming from the following page.It is possible to do this entirely in webdna, but you won't be able to use a simple [referrer] tag, there's more to it than that. The easiest solution I've seen yet -- besides simply tell visitors to use their browser's Back button -- is to use the javaScript example posted earlier in this thread. That is, if you don't mind relying on JavaScript ...By the way, [referrer] is a tag, not a command ... :) Sincerely, Kenneth Grome WebDNA Consultant
