auto-complete views expose filter [closed]

Question

I have created an expose filter to display a list of articles written by respective author. For that purpose I have create a view and done following things:

1. Relationship - Content: Author
2. Filter Criteria - User: Name (raw)

Now, I am able to get articles written by respective author.

Question: How to make this filter autocomplete? I have used Views Autocomplete Filters module, does not have a luck.

Answer 1

You can add autocomplete to any form:

1. Use hook_form_alter to set an autocomplete path for the field
2. Define a menu callback for the autocomplete path in hook_menu
3. Have the callback query the database

There is a decent write up at http://www.elevatedthird.com/blog/enable-ajax-autocomplete-drupal-7-webform-textfield - make sure you are targeting the right form in hook_form_alter and that your query goes against the users table instead of the node table.

        function demo_form_alter(&$form, &$form_state, $form_id) {
        //dpm($form);
        if ($form_id == 'views_exposed_form' && $form['#id'] =='views-exposed-form-game2-page') {
        $form['name']['#autocomplete_path'] = 'name/autocomplete';
        }
        }

        /**
        * Implements hook_menu().
        */
        function demo_menu() {
        $items = array();
        $items['name/autocomplete'] = array(
        'title' => 'name autocomplete',
        'page callback' => 'name_autocomplete',
        'access callback' => 'user_access',

        function name_autocomplete($string = '') {
        $matches = array();
        if ($string) {
        $result = db_select('users')->fields('users', array('name'))->condition('name', db_like($string) . '%', 'LIKE')->range(0, 10)->execute();
        foreach ($result as $user) {
        $matches[$user->name] = check_plain($user->name);
        }
        }

        drupal_json_output($matches);
        }
