Re: [Tutor] cgi scripts
Actually, that's good to know. I was thinking it was going to be pretty hard to debug if I couldn't tell the difference between HTML errors and Python errors.

I think I'd better brush up on my HTML skills. Poorly formed HTML won't give an internal server error. That is due to something more serious such as a syntax error in your program. I always configure cgi scripts so that I can also run them from the command line. That can be an effective way to catch errors otherwise obfuscated by the browser. Although I don't use windows any longer, I recall that pythonwin was a nice IDE to use and it probably has a syntax checker. tim ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
Re: [Tutor] cgi scripts
Bt Crash, I mean the browser displays: Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request. The code I sent before had a silly mistake in it. Here is a better example of the things I am trying and failing at. I can print a single key. I can iterate over the keys, just printing out hello for each iteration. But I can't figure out how to iterate over all the keys printing out somethinf sensible. #!C:\python25\python.exe import cgi, sys # import cgitb; cgitb.enable() #Send errors to browser sys.stderr = sys.stdout #Parse data from form data = cgi.FieldStorage() #Send response to browser print Content-type: text/html\n print titleCGI Form Response/title\n print h2This is the data passed to the cgi script/h2P # This next bit works and I can see a list of keys displayed in the browser print Version 4: data.keys()\n print br print data.keys() # This next bit also works and I can see the value of the variable JQuiz_q01_score print P- print BJQuiz_q01_score = , data[JQuiz_q01_score].value # However, whenever I try to iterate over all the keys, I get the Internal Server error print P- for k in data.keys(): print BRdata[k].key # I have also tried data[k] #data.key[k] #data[k].value # and many other random combinations. ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

Re: [Tutor] cgi scripts
Thanks guys, This works :) field_list = 'ul\n' for field in data.keys(): field_list = field_list + 'li%s : %s/li\n' % (field, data[field].value) field_list = field_list + '/ul\n' print field_list I think the problem wasn't in getting the keys and values, but I might have been producing illegal HTML code before. I think I'd better brush up on my HTML skills. Jim Alan Gauld wrote: Jim Morcombe [EMAIL PROTECTED] wrote The code I sent before had a silly mistake in it.

With bad HTML you will see *something* in the browser, even if only a blank page, and you can view source to see the actual code.
