If you chose to tag the content on your site, a “tag-cloud” may be an ideal way to display tag navigation for users.
To display a tag cloud start with the following parameters:
1, //size of least used tag 'largest' => 2, //size of most used tag 'unit' = => 'em', //unit for sizing 'number' => 45, //displays at most 45 tags 'format' => 'flat', //displays the tags in flat 'orderby' => 'name', //order the tags by name 'order' => 'ASC' //sort the tags in ASCENDING order )); ?>
