sibling taxonomy terms

Question

Drupal 7

I have a vocabulary with hierarchical terms countries and cities.

I have a view with context filter=cityA ( parent country A)

How I can display into a block all cities from country A ( siblings of cityA from vocabulary)?

Thanks

You can try using taxonomy_get_children($termid) to get children of term and then taxonomy_get_parents($termid) and again taxonomy_get_children() to get the siblings . The following is the code I used in such situation :

<?php

if (isset($page['#views_contextual_links_info']['views_ui']['view']->args[0])){
    $termid = $page['#views_contextual_links_info']['views_ui']['view']->args[0];
    $terms = taxonomy_get_children($termid);

    if (empty($terms)) {
        $parent = taxonomy_get_parents($termid);
        $terms = taxonomy_get_children(key($parent));
    }
}

if (isset($node->field_category['und'][0]['tid'])) {
    $termid =  $node->field_category['und'][0]['tid'];
    $terms = taxonomy_get_children($termid);
}

?>
