Add a unique ID to Drupal Views list groupings

Question

I'm using Views 3 in Drupal 7 to output a list of fields and using a grouping field to generate separate lists. I need each of the groupings to have a unique ID attribute applied to the < ul > but they don't by default.

As far as I'm aware I would need to edit the views-view-list.tpl.php template but I don't know how to achieve a unique ID per iteration.

Can anyone help please?

Answer 1

For future reference: Put a div around everyting in view-views-list.tpl.php. You can (ab-)use the $title to generate unique (but consistent) id's.

Do it like this:

<?php $id = str_replace('FOR ALL UNWANTED CHARS','',$title); ?>

<div id="<?php print strtolower($id); ?>">

Answer 2

You can use the $view->dom_id variable. It is a unique id for that views instance.

In your .tpl.php file:

<?php print $view->dom_id; ?>

From comments in modules\\views\\theme\\theme.inc:

<?php
    // It is true that the DIV wrapper has classes denoting the name of the view
    // and its display ID, but this is not enough to unequivocally match a view
    // with its HTML, because one view may appear several times on the page. So
    // we set up a hash with the current time, $dom_id, to issue a "unique" identifier for
    // each view. This identifier is written to both Drupal.settings and the DIV
    // wrapper.
?>

Answer 3

easiest way I can think of off the top of my head...

<?php print $wrapper_prefix; ?>
  <?php if (!empty($title)) : ?>
    <h3><?php print $title; ?></h3>
  <?php endif; ?>
  <ul id="<?php echo uniqid(); ?>">
    <?php foreach ($rows as $id => $row): ?>
      <li class="<?php print $classes_array[$id]; ?>"><?php print $row; ?></li>
    <?php endforeach; ?>
  </ul>
<?php print $wrapper_suffix; ?> 

that would go in your views-view-list.tpl.php file.
