There are a couple issues depending on what exactly you're trying to do.
You're getting an empty string because your checkboxes have no "value"
attribute. Also, you should probably replace your paragraph tags with
label tags. I don't know if it's a requirement, but I think checkboxes are
supposed to have the same name attribute.
Here is an example:
<form method="POST">
<input type="checkbox" id="curly_1" name="curly" value="Some Value">
<label for="curly_1">check_1</label>
<input type="checkbox" id="curly_2" name="curly" value="Some Other
Value">
<label for="curly_2">check_2</label>
<button type="submit">Submit</button>
</form>
def POST(self):
i = web.input(curly = []) #curly = [] makes sure that we don't lose
values from the checkboxes.
web.header("Content-Type", "text/html; charset=utf-8")
return i
If you post the above form to our POST method with both boxes checked,
you'll get this:
<Storage {'curly': [u'Some Value', u'Some Other Value']>
Hope this helps.
