follow-up to FieldStorage

[John Salerno]

If I want to get all the values that are entered into an HTML form and
write them to a file, is there some way to handle them all at the same
time, or must FieldStorage be indexed by each specific field name?

AFAIK, FieldStorage is a somewhat dict-like object, but I'm not sure it
supports the whole dict interface. At least, it does support keys(), so
you should get by with:

for k in fs.keys():
print >> myfile, k, ":", fs[k]

But reading the doc may help...

Thanks. The cgi docs don't seem to get into too much detail, unless I
wasn't thorough enough. But your method seems like it might work well if
I can't find something after another read through.

On the other hand, 45 seconds with the source code shows that "class
FieldStorage" has member functions called "keys()" and "has_key()".

Use the source, Luke. To me, that's one of the big beauties of Python.

FWIW, reading the source is not even needed to know this:

Very interesting!

FWIW, reading the source is not even needed to know this:

not to mention:
Help on class FieldStorage in module cgi:

class FieldStorage
| Store a sequence of fields, reading multipart/form-data.
|
| This class provides naming, typing, files stored on disk, and
| more. At the top level, it is accessible like a dictionary, whose
| keys are the field names. (Note: None can occur as a field name.)

(followed by a detailed description of the field objects, and
descriptions of all methods on the dictionary-list object).
