Sometime you may have to get the drupal views exposed filter form programmatically, Let say you implemented the custom search functionality in your site at <your-site.com>/customsearch with views module where you showing listing of different content type with summery and you exposed the filters (e.g simple text box) so that user can filter down the result based upon the search term he type in exposed search box. You may have to show the same exposed search form on site home page so that when user search something on homepage he will be redirected to your custom search page. You can get the views exposed form with following code:
<?php $view = views_get_view('your_views_machine_name'); $view->set_display('Views display name'); $view->init_handlers(); $exposed_form = $view->display_handler->get_plugin('exposed_form'); print $exposed_form->render_exposed_form(true); ?>
As code is self explanatory, the views_get_view function will get your view from database, then set_display method on view object will set the display of your view. init_handlers method will initialise the handlers then with the help of get_plugin method of display_handler you can get the exposed form and render it.
