[web2py] Advanced Live Search
In the example in chapter 3 of the book, mywiki application we have:
def search():
an ajax wiki search page
return dict(form=FORM(INPUT(_id='keyword',_name='keyword',
_onkeyup=ajax('callback', ['keyword'], 'target');)),
target_div=DIV(_id='target'))
def callback():
an ajax callback that returns a ul of links to wiki pages
query = db.page.title.contains(request.vars.keyword)
pages = db(query).select(orderby=db.page.title)
links = [A(p.title, _href=URL('show',args=p.id)) for p in pages]
return UL(*links)
Assume that we would like to search a keyword both in the title and
the body of the wiki in the following manner:
1. The default search searches in the title and body both.
2. We have two check boxes with the attribute name set to title and
body respectively. Initially both are checked. But the user can
uncheck one of them to request the application to search only in the
other field. What is the best way to achieve this?
Specifically, if I add two checkboxes to the search function return
expression, i.e.:
INPUT(_type=checkbox, _name=title ), Title,
INPUT(_type=checkbox, _name=body), Body,
how I can check whether they are checked or not from within the
callback function? I'd like to use these two checkboxes to express
which fields of the database should be searched.

Hi Anthony.
Thanks for your answer. I seem to be unable to replicate what you
said. How do you test if the checkboxes are checked?

You can submit multiple inputs (via id) with the ajax() function, so if you
give your checkbox inputs id's (e.g., id='title' and id='body'), you should
be able to do:
ajax('callback', ['keyword', 'title', 'body'], 'target')
and in the controller, access request.vars.keyword, request.vars.title, and
request.vars.body (I think title and body will be None if they are not
checked).

I figured this work if I have the name attributes for the checkboxes
(and in my case the name attributes are the same as the id
attributes). Thanks again!
