How to check file existance?!
It is not file, it is object, but anyway...
I want to upload file, but I don't know if it exists. So:
<dtml-call "PARENTS[0].manage_delObjects('filename')"> <dtml-call "PARENTS[0].manage_addFile('filename',file,title=REQUEST['title'])">
If I omit manage_delObjects, file will be uploaded once, then zope barks. If I place manage_delObjects, the file HAVE to exist before I upload. Now how to write this code in a such way that it would handle uploads in any case?
<dtml-if "'filename' in PARENTS[0].objectIds()"> Oleg. ---- Oleg Broytmann http://www.zope.org/Members/phd/ phd@phd.pp.ru Programmers don't die, they just GOSUB without RETURN.
