Weird update problem

Weird update problem

I have successfully implemented Data Assist on two separate databases on two different areas of my client's website. It works well. The pages for search, results and details work fine.

But here's where the weirdness comes in. When I click through to either create a new record (in either database) or to update a record (again, in either database) the page loads properly, but it loads an empty iteration of the page's template file, and then the page that was formatted for the update/new record.

Take a look here:
library_Search.php

Search for Aztec, then click the Update link and you'll see what I mean.

I have walked backwards with this one, starting with just the raw code from the page when Dreamweaver created it from the template. The "page doubling" only occurs when I paste in the Data Assist code before the <!DOCTYPE tag. Once that code is inserted, the "page doubling" starts.

Any ideas what might be going on here?

Errors too

The update post fails too, and shows errors on lines 90 and 99: Is the problem with the URL redirect?

  The "page doubling" only occurs when I paste in the Data Assist code before the <!DOCTYPE tag. Once that code is inserted, the "page doubling" starts.  



it sounds to me like you are pasting the code for the entire page, not just the insert or update record behavior.


the work flow should not include any copying from one page then pasting it to another.

If you are not using the wizard to create the pages, you should be creating the update form on your page, then applying the Up[date Record server behavior to it, I'm not sure why you are Copying code from one page to another, but that is likely the source of the page doubling and also of the headers already sent error.
