Hi, I want to check selected files for upload before. My script is this one: ------------------- id=context.REQUEST.form['id'] descr=context.REQUEST.form['desc'] fileToUpload=context.REQUEST.form['file'] context.manage_addFile(id,fileToUpload,descr) ------------------- The point is that, if I enter a non-existing file in the "file" input field in the form that calls this script, this code creates a zero-bytes files, instead of warning me... how can I change this code to detect "file not found error"? Working with Zope 2.3 (Python 1.5) Thanks, _______________________________________________________________ Copa del Mundo de la FIFA 2002 El único lugar de Internet con vídeos de los 64 partidos. ¡Apúntante ya! en http://fifaworldcup.yahoo.com/fc/es/
