Drupal Views2 Exposed Form how to change

Question

I have a View with an exposed form . I am trying to a few things on it. Ideally I would like to have a dropdown that fires the form with no button. If that is not possible t

Answer 1

Both of the above are fine but I found out that altering the form might not always lead to desirable results, mainly because exposed filters are themed using a specifc theme template. The proper way of changing the theme would be to override the views-exposed-form.tpl file in your theme's folder. Bear in mind that this will apply to all exposed filter forms, to theme a specific one, you will need to use a different name for that filename, like:

views-exposed-form--TITLE--DISPLAY.tpl.php
views-exposed-form--TITLE.tpl.php

and some others, you can check the Theme: Information section of your views for template naming conventions.

Answer 2

Or, you could use a preprocess function to alter the form even before it is build. I wanted to change the text on the button, so I did this:

function MYTHEME_preprocess_views_exposed_form(&$vars, $hook) {

  // only alter the jobs search exposed filter form
  if ($vars['form']['#id'] == 'views-exposed-form-jobs-search-page-1') {

    // Change the text on the submit button
    $vars['form']['submit']['#value'] = t('Search');

    // Rebuild the rendered version (submit button, rest remains unchanged)
    unset($vars['form']['submit']['#printed']);
    $vars['button'] = drupal_render($vars['form']['submit']);
  }
}

This module provides an auto-submit among other things http://drupal.org/project/views_hacks

This module is great to improving exposed filters http://drupal.org/project/better_exposed_filters

Answer 4

If you want the drop-down to fire, I'd use JavaScript instead of hacking the module as Eaton suggests.

Basically, you can modify the text with hook_form_alter as Eaton suggests, then use in the same hook_form_alter, add a call to drupal_add_js with your custom JS which hides the button and submits the form on the onChange handler of the select drop-down. You want that submit button there for those 10% of users for whom the JS fails.

Answer 5

You should be able to use hook_form_alter() (http://api.drupal.org/api/function/hook_form_alter) to change the form as it's built, modifying the fields in question when that particular view is being displayed. You can nuke the submit button, add a #theme function that calls the drupal_add_js() function, and so on.

As long as the GET params come in the way views expect them, everything will work fine -- it was designed that way to allow bookmarking of pages with exposed filter settings, etc. The important part is to make sure you're doing the form mangling in your own module's hook_form_alter() function, so that it won't make other views driven stuff choke.
