When a form is submitted, the submitted values will be in request.post_vars
as well as request.vars (the former is specifically for variables submitted
via post requests, whereas the latter includes both post and get
variables). So, you could do:
if request.vars:
do something with request.vars.search_keyword
else:
return dict()
However, if you want to take advantage of web2py's form creation and
processing, you can use the FORM or SQLFORM.factory helpers as described
here: http://web2py.com/books/default/chapter/29/7. In particular, if you
want to write all the HTML manually but just use web2py's form processing
in the controller, see:
http://web2py.com/books/default/chapter/29/7#SQLFORM-in-HTML (same would
apply to using SQLFORM.factory). As an alternative to completely manual
HTML, you might consider SQLFORM.factory along
with http://web2py.com/books/default/chapter/29/7#Custom-forms.
