I posted a question earlier but it didn''t come out that clear and I have spent the whole day looking this up. Any help would be much appreciated. Here goes round 2: I have several textareas on the screen (anywhere from 1 - 5). Right now I have them in a form and am using a submit button to pass the values to the controller. What I need to do is pass these values to the controller using links located outside of the actual form. When the link is click the values from the textareas are passed to the controller along with a :question parameter. The values of the textareas are saved into the db and the :question param is used in a query and then the page is redirected to another page with the result from the query as another param. The part I cannot seem to find an answer for is how to pass the values of the textareas to the controller using link_to(), not link_to_remote. Or how do you access the textarea values and attach them to :value1 => ???? I really hope that made more sense.

I initially tried it with a remote_function and used that with an onunload event but it would only work 50% of the time. I also tried onclick with the same remote_function but I think the responses were too long and it would only grab half of it before moving on. Oh well, I guess I am going to have to say I can''t do it the way they want it.

Sorry I misread your response. How would I trigger the form submit from a link? That is what I have been looking to do all day and could only find ajaxy ways of doing it which wouldnt allow me to redirect afterwards. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

At that point you might as well just be styling the form''s submit button to not look like a button.

So you''ve got a traditional form generated by form_for, with the
expected submit button etc. That all works just as you want it to. Now
you want to *in addition to the existing submit button* offer a link up
at the top of the page that will submit that same form. Do you want
that link to a) have exactly the same effect as the submit button--no
more, no less, or b) have the same effect as the submit button *plus*
tack an extra parameter & value onto :params? (Or c) something else?)
If a)--I would think Fred''s earlier suggestion to use javascript to do
a
my_form.submit() should work. I don''t know the best way to get rails
to
generate that (link_to_function("click me",
"my_form.submit()") maybe?)
but no doubt others here will. If b) it''s probably a little more
involved (javascript stuffs your parameter in a hidden field created in
your form maybe, and *then* does a my_form.submit()?).
HTH,

The only option I can think of is to use some ajax and have it pass a parm in when someone clicks the link and have it return nothing and then have that same click call form.submit() afterwards. I am about to try this now but it seems like 1) it will be really slow and 2) it might not work. We will see. I just dont know a way to pass the extra param as well as submitting the form.
