Theming CCK Views the Agaric Way (with background)

Note that Views and CCK's imagefield module have excellent imagecache integration and you only need these steps if you want very fine-grained control-- in our case, automatically populating the ALT text of the image with the node title.

/admin/build/views/wizard

and

http://agaricdesign.com/note/how-theme-lots-views-agaric-way

and then a little

<?php
print '<pre>';
print_r(get_defined_vars());
print '</pre>';
?>

Show us what we have and what we want:

add in some knowledge from theming CCK the Agaric way

Resolution

If you think like we do you'll have something like this in template.php:

<?php
/**
 * Theme views invoked by view-specific callbacks (see below).
 */
function phptemplate_views_template($template, &$view, &$nodes, &$type) {
  $fields = _views_get_fields();
  $taken = array();

  // Set up the fields in nicely named chunks.
  foreach ($view->field as $id => $field) {
    $field_name = $field['field'];
    if (isset($taken[$field_name])) {
      $field_name = $field['queryname'];
    }
    $taken[$field_name] = true;
    $field_names[$id] = $field_name;
  }

  // Set up some variables that won't change.
  $base_vars = array(
    'view' => $view,
    'view_type' => $type,
  );

  $items = array();
  foreach ($nodes as $i => $node) {
    $vars = $base_vars;
    $vars['node'] = $node;
    $vars['count'] = $i;
    $vars['stripe'] = $i % 2 ? 'even' : 'odd';
    foreach ($view->field as $id => $field) {
      $name = $field_names[$id];
      $vars[$name] = views_theme_field('views_handle_field', $field['queryname'], $fields, $field, $node, $view);
      if (isset($field['label'])) {
        $vars[$name . '_label'] = $field['label'];
      }
    }
    $items[] = _phptemplate_callback('views-list-' . $template, $vars);
  }
  if ($items) {
    return theme('item_list', $items);
  }
}

/**
* Create functions to catch views' check for theme overrides, and
* pass on to a general function to call templates to output views.
*
* assumed faster than checking if a .tpl.php file exists for every view?
*/
function phptemplate_views_view_list_promo_badges_main(&$view, &$nodes, &$type) {
  return phptemplate_views_template('promo_badges_main', $view, $nodes, $type);
}
function phptemplate_views_view_list_promo_badges_earthkeepers(&$view, &$nodes, &$type) {  // yeah so it's not perfectly named anymore
  return phptemplate_views_template('promo_badges_main', $view, $nodes, $type);
}
?>

And the real excitement in views-list-promo_badges_main.tpl.php, with both files in your active theme directory, of course:

<p><a href="<?php print $field_link_url ?>">
<?php
if (function_exists('_imagefield_file_load')) {
  $file = _imagefield_file_load($node->node_data_field_promo_graphic_field_promo_graphic_fid);
  print theme('imagecache', 'sidebar', $file['filepath'], $title);
}
?>
</a></p>
