Michael, Try something like, untested but looks good to me: <dtml-with logos> <dtml-if "_['logo'] in objectIds(['Image'])"> <dtml-var "_.getitem(_['logo'])"> </dtml-if> </dtml-with> hth Phil ----- Original Message ----- From: "Michael Fox" <michael@centurysoftware.com.au> To: <zope@zope.org> Sent: Wednesday, May 23, 2001 2:01 AM Subject: [Zope] Testing if an image exists
Hello,
I have a folder called 'logos' which contains several images, and a session variable called 'logo'.
I need to test if my session variable 'logo' matches the ID of an image object in my 'logos' folder.
eg. I have an image in my 'logos' folder called 'mylogo' and the value of my session variable is 'mylogo'.
So far I've come up with this dtml, which doesn't seem to work..
<dtml-with logos> <dtml-if _['logo']> <img src="logos/<dtml-var logo>"> <dtml-else> no logo to display </dtml-if> </dtml-with>
Has anyone had a similar need as above? can this be done?
Regards,
Michael Fox
