I am looking at the code example provided by Facet API Bonus module in the section Rewrite facet items via callback function
function HOOK_facet_items_alter(&$build, &$settings) { if ($settings->facet == "YOUR_FACET_NAME") { foreach($build as $key => $item) { $build[$key]["#markup"] = drupal_strtoupper($item["#markup"]); } } }
How would I modify that to override the label of a specific facet item?
