How do I change submit URL for exposed search filter?

Seems that specific problem is with Panels.

The exposed form is basically a block which have no sense of context, therefore setting the URL from the view pane doesn't affect exposed filters in a block.

Therefore one way to go is to use hook_form_alter:

/** * Implements hook_form_alter(). */ function foo_form_alter(&$form, $form_state, $form_id) { if ($form_id == 'views_exposed_form') { $form['#action'] = current_path(); } } 

Or:

/** * Implements hook_form_views_exposed_form_alter(). */ function foo_form_views_exposed_form_alter(&$form, &$form_state) { if ($form['#id'] == 'views-exposed-form-foo-default') { // Or: if ($form['#action'] === '/foo') $form['#action'] = '/bar'; } } 

Or by extending Views handler, for example:

class foo_handler extends views_handler_field { /** * Add to and alter the form. */ function views_form(&$form, &$form_state) { // Submit to the current page if not a page display. if ($this->view->display_handler->plugin_name != 'page') { $form['#action'] = current_path(); } } } 

Alternatively content pane can be used which can override the path, instead of using exposed form. See this issue for more details.
