While converting my Netoteric site to Drupal, there was a small problem with the portfolio page. The items in it alternate between left and right. Views Theme Wizard didn’t work. It was time for more desperate measures.
I added a function in my custom template file, which created an index number and assigned it to a node member.
/**
* Display the nodes of a view as plain nodes.
*/
function theme_views_view_nodes_portfolio($view, $nodes, $type, $teasers = false, $links = true) {
$i=0;
foreach ($nodes as $n) {
$node = node_load($n->nid);
$node->__views_index_number = $i++;
$output .= node_view($node, $teasers, false, $links);
}
return $output;
}
theme_views_view_nodes_portfolio overrides the Views default theme function, but only for the portfolio view.
Then inside the contemplate body template I just added a modulo function to alternate between left and right:
class=“thumbnail __views_index_number % 2 ? ‘right’:‘left’)?>”>
And voila! Now the images alternate between left and right…
