My first take would be something like (untested): <dtml-unless mc_name> <dtml-call "REQUEST.set('mc_name','Clipname')"> </dtml-unless> Phil ----- Original Message ----- From: "Gitte Wange" <gitte@mmmanager.org> To: <zope@zope.org> Sent: Wednesday, May 16, 2001 1:22 PM Subject: [Zope] Testing if a string isn't empty

Hello,

I am trying to make some dtml code that tests if a string contains text (because if the string is empty it must be set to contain 'Clipname').

Right now the code looks like this: <dtml-if expr="mc_name == ''"> <dtml-let mc_name="'Clipname'"> <dtml-call sqlAddClip> </dtml-let> </dtml-if>

How do you do it - because the above doesn't work.
