Multiple exposed form blocks

Not with the same URL, unfortunately. You might be able to do some stuff with blocks with exposed filters, and exposing the filters in a block (that's weird) and have them all go to the same URL, but it only really works if the base 'page' filter has *all* of the filters as possible and any that might not be present are set to be optional. That *could* work. Maybe.

This might be possible with a custom exposed form plugin.

I believe I had a similar issue and this is how I solved it.

What I have:
I have one views page with a path named, say content_list. This page includes an exposed filter of 3 taxonomy term drop down lists.

What I need:
I want to add another block with exposed filters which I can put on every page of the site. Using this exposed filter form will redirect to the content_list page and filter the content there.

How I solve it:
I add another page display on the same view which looks exactly the same as the original page. The only differences are: I name the path content_list2 and the exposed filters are displayed in a block. I show this block on every page except on content_list.

In a custom module I add this:

/**
* Implementation of hook_form_alter()
*/
function custom_form_alter(&$form, $form_state, $form_id) {
	
  if ($form['#id'] == 'views-exposed-form-your_views_page_id') {
     //override /content_list2 with /content_list	
     $form['#action'] = '/content_list';
  }
}

Note: I believe this would only work if the original content_list page has the same filters enabled as the exposed block...

It's a tweak, but I hope it is helpful for others as well.

Cool. I think people could use your code

don't need a custom module to override action path
can also use something like this in your template.php

function THEMENAME_preprocess_views_exposed_form(&$vars) {
  if ($vars['form']['#id'] == 'views-exposed-form-VIEW-NAME-ID') {
     //alter the $form array here
     $vars['form']['#action'] = 'path_to_view';
  }
}

instead of THEMENAME can also use "phptemplate"
EDIT:warning: this is untested code

above code does not do the job
need to re-render the form and I don't know how to do it

Any ideas how to do this on Drupal 7?

The issue is not solved in Drupal 7.

From some ideas I found on the web while trying to solve this problem, I wrote a module that provides one additional block. Give it a try, maybe it works for you: https://drupal.org/sandbox/berliner/2087181. I explained the rationale behind it here: http://blog.dev030.com/posts/additional-exposed-filter-block-views

#13 is working great for me so far. Exactly what I was looking for. Thank you berliner!
