I am trying to create a tag cloud that combines different post types. When I do a generic wp_tag_cloud, it only pulls the tag from posts, but if I add the custom post type that I want to include in the args, then it displays tags from those posts. However, if I have the same tag in a post and in a custom post type, it shows up twice, instead of being combined.
For example, if I have a tag of “trampolines” in a post and the same tag in a custom post type of portfolio, then the tag cloud will display trampolines twice instead of weighting it as double. Any ideas how I can accomplish this?
<?php $args = array(
'smallest' => 8,
'largest' => 18,
'unit' => 'pt',
'number' => 450,
'format' => 'flat',
'separator' => "n\ ",
'orderby' => 'name',
'order' => 'ASC',
'exclude' => null,
'include' => null,
'topic_count_text_callback' => default_topic_count_text,
'link' => 'view',
'taxonomy' => array('post_tag', 'portfolio_tag'),
'echo' => true
); ?>
Tags: <?php wp_tag_cloud( $args ); ?>
As John said in his comment, you have two taxonomies with separate terms. If both posts and portfolios are to share tags, instead of using a new taxonomy just extend post_tags to portfolio custom post type :
