I'm often failing to describe problems correctly, kindly bear for that. lets revise, In my login page I've two tables used district and userdetail. district table ( district_code, distname, location ...) userdetail (username ,password, empcode ,district_code ,ulevel ...) user to district is n:1 mapping. So I need to have both these tables info in the XUF. Anyway, i'm trying cookies as advised. tell me how do i set a request var in my python script. i tried : request.set('invalid','1') return context.REQUEST.RESPONSE.redirect('index_html') // back to login page I'm using 'invalid' hidden field to display the 'login failure' msg. <body tal:define ="valtest request/form/invalid|nothing">// define <b tal:condition="valtest">Invalid Password .....Re Type</b>//msg nothing is happening I'm working hard to get it done in Zope's way plz help -- Share the vision of difference with ME
