Question

I am using Rails 2.2.2 and I would like to add an id to the html form code generated by the form_tag.

<% form_tag session_path do -%>       <% end -%> 

Currently produces:

<form action='/session' method='post'> </form> 

Would like it to produce:

<form id='login_form' action='/session' method='post'> </form> 

The api isn’t really any help and I’ve tried adding various combinations of

:html => {:id => 'login_form'} 

with no luck.

For <element>_tag you specify HTML attributes directly, as follows:

<% form_tag session_path, :id => 'elm_id', :class => 'elm_class',                           :style => 'elm_style' do -%>    ... <% end -%> 

It is for <element>_remote_tag constructs that you need to move the HTML attributes inside a :html map:

<% form_tag form_remote_tag :url => session_path, :html => {                             :id => 'elm_id', :class => 'elm_class',                             :style => 'elm_style' } do -%>    ... <% end -%>
