hmmm still not 100% sure what you mean....does this example help?

If you had a file called register.rhtml and a model called user....

<% form_for :user do |form| %>

<div class = "form_row">    <label for="screen_name">Screen name:</label>   <%=form.text_field :screen_name%> </div>

<div class = "form_row">   <%=submit_tag "Register!", :class => "submit" %> </div>

<% end %>

In the controller in the "register" method (I think ruby takes the controller method name from the name of the .rhtml file) you can then receive the form using "params[:user]" and then do @user = User.new(params[:user]) to create a new user....

Does this help? Or am I off track?

Hmm....Sorry if my question is not clear. What I was trying to do is to get the form's id, and try to submit it using a link outside the form.

Example:

<% form_for :user, :url => { :action => :save_user}, :html => { :id => "id_of_form" } do |form| %>

<div class = "form_row">    <label for="screen_name">Screen name:</label>   <%=form.text_field :screen_name%> </div> <%= end %>

  <%=link_to_function "Save", "myform.submit();" %>

I want to ask is there anyway to get id_of_form which is the form's id ? Correct me if any part of my code is wrong. Is it possible to submit form with the submit link outside of the form?

Thanks

hmm how about:

<%=link_to "Save", {:action => "save", :form_id => "user"} %>

does that work?

the answer may well be yes buy you can just put an extra hidden input
tag in the form like: <input type="hidden name="formid" value="1"> and access it via params[:formid]

Hi,

Just to make sure, where should I put this hidden field ? I tried placing it in my side bar but can't get value

Thanks

sorry also forgot to close the tag... its:

<input type="hidden" name="formid" value="1"/>

.....put this hidden field anywhere between <form > and </form> for
the form you want to reference
