Cloud displayed under Popular Tags title
Cloud returned as array but not displayed
The variable $tag will contain the tag cloud for use in other PHP code
Display a Category Cloud
Use the taxonomy argument to cause a cloud of categories to display.
Change Title Text of Cloud Links
Use the topic_count_text_callback argument to pass in a new callback function. The original function default_topic_count_text() is located in /wp-includes/category-template.php This example changes the title text from the default “topics” to “pictures”.
<?php wp_tag_cloud( array( 'topic_count_text_callback' => 'my_tag_text_callback' ) ); function my_tag_text_callback( $count ) { return sprintf( _n( '%s picture', '%s pictures', $count ), number_format_i18n( $count ) ); } ?>
