Drupal 7 Ajax Forms

I am using Drupal 7, and I am building a web site, that has a contact form in the footer which should appear in every page. The requirements was to make this form work via Ajax, all examples I found on Internet was form that related to node.

So when I tried to apply the same concept, I faced the problem of rendering the form, so I have passed it to the template as a parameter like this:

$vars['node']->contactForm = drupal_get_form('nilecode_form');

When I render the form by using drupal_render_children($node->contactForm), 开发者_C百科all the fields were rendered but with no wrapping form tag.

So after frustration, and not very useful IRC chats, I am thinking to do it by using normal Ajax request.

Before doing so is there any solution, before doing it the bad way?

Thanks.

Take a look at my ajax form examples, the best way of achieving this is using a theme function for the form: http://monchacos.com/monchacos/code/creating-forms-template-file-ajax-included
