Re: [Zope] advice to track graphics rendering in DTML or python(script)

29 Oct 2001

      Hi Trevor,
If I understand your question correctly, you want to send an image only when
there one can be found under the UI .
The problem here is, that img needs to have a src that points to a valid
picture, otherwise you get an ugly empty picture symbol.

I tried the following script which I think solves your problem:
It has one parameter called UID

return context[UID].data

It is called as follows:
<html>
<body>
  <img src="http://localhost:8080/bevan/assets/pic?UID=halle.gif">
</body>
</html>

where bevan/assets is a folder with images.

Robert

cant that be named
http://zope/images/header.gif?uid=Alkj9876
then you can ask for the id with
<dtml-var uid>
Robert,
How are you? Thanks for the reply,
I know this works for a webpage rendered from Zope.
But what about a page rendered externally, that includes
<img src="http://zope/images/header.gif?uid=Alkj9876">
How do I capture the UID from a REQUEST for an image?
Thanks,
Trevor
...
there is also some way to get the URL with all the parameters that where
used. However I do not find it.

I have a template that needs to render a different header GIF,
based on a
URL variable.
eg: http://zope/images/header.gif?Alkj9876
How do I capture the "UniqueID" in DTML so I can process a DTML-If and
record the ID?
TIA,
Trevor
