taxonomy_link

Versions
5 – 6: taxonomy_link($type, $node = NULL)

Implementation of hook_link().

This hook is extended with $type = 'taxonomy terms' to allow themes to print lists of terms associated with a node. Themes can print taxonomy links with:

if (module_exists('taxonomy')) { $terms = taxonomy_link('taxonomy terms', $node); print theme('links', $terms); }
