Okay, got it sorted (finally)!
Here's the code to do multiple fields with some random file uploads.
I hope this helps someone else. (How does one go about getting this
added to the cookbook?)
I was wrong about the ** not being needed. Yes, as a matter of fact,
I /am/ a goober. Often.
A couple gotcha's not mentioned on the cookbook page:
1) inputs to web.input() *must* be str strings and not unicode
strings. These are not the same things, apparently. That wasn't
clear to me before...;^)
2) If your file fields are going to be getting binary data (uploading
images), you must put _unicode=True as the first argument to web.input
().
--------------------------------------------
import web
urls = ('/upload', 'Upload')
class Upload:
def GET(self):
# put the list of image names in the session
# NOTE: These /must/ be str strings, not unicode!!!!
# These are the names of the fields on the form. They must be
stored in the session
# so that they can be picked up during the post. If the user
waits to submit these until
# after the session dies, the file uploads won't work.
web.config._session['images']=['image-2.0','image-4.0']
return """<html><head></head><body>
<form method="POST" enctype="multipart/form-data" action="">
<p><input type="input" name="question-1.0" />First question
<p><input type="file" name="image-2.0" />First image
<p><input type="input" name="question-3.0" />Second question
<p><input type="file" name="image-4.0" />Second image
<br/>
<input type="submit" />
</form>
</body></html>"""
def POST(self):
# get the image names
images = web.config._session['images']
myfiles = {}
for k in images:
myfiles[k] = {}
x = web.input(_unicode=True,**myfiles)
web.debug(x['image-2.0'].filename) # This is the filename
web.debug(x['image-2.0'].value) # This is the file contents
web.debug(x['image-2.0'].file.read()) # Or use a file(-like)
object
raise web.seeother('/upload')
if __name__ == "__main__":
app = web.application(urls, globals())
web.config._session = web.session.Session(app, web.session.DiskStore
('/tmp/sessions'), {'count': 0,'logged_in':0})
app.run()
