get_the_category_list
Description
Retrieve category list in either HTML list or custom format. Generally used for quick, delimited (eg: comma-separated) lists of categories, as part of a post’s entry meta. For a more powerful, list-based function, see wp_list_categories().
Usage
<?php get_the_category_list( $separator, $parents, $post_id ); ?>
Parameters
$separator- (string) (optional) Optional, default is empty string. Separator for between the categories.
- Default: empty string
$parents- (string) (optional) Optional. How to display the parents. Values: ‘multiple’, ‘single’, empty string
- Default: empty string
$post_id- (int) (optional) Optional. Post ID to retrieve categories.
- Default: false
Return Values
(string)
Notes
Categories are ordered by name regardless of the parent-child category relationship. See this example from wp_list_categories() to display the Post categories with the category relationship intact.
Examples
Implementation in WordPress default Twenty Eleven theme
In content-single.php:
<?php/* translators: used between list items, there is a space after the comma */$categories_list = get_the_category_list( __( ', ', 'twentyeleven' ) );/* translators: used between list items, there is a space after the comma */$tag_list = get_the_tag_list( '', __( ', ', 'twentyeleven' ) );if ( '' != $tag_list ) {$utility_text = __( 'This entry was posted in %1$s and tagged %2$s by <a href="%6$s">%5$s</a>. Bookmark the <a href="%3$s" title="Permalink to %4$s" rel="bookmark">permalink</a>.', 'twentyeleven' );} elseif ( '' != $categories_list ) {$utility_text = __( 'This entry was posted in %1$s by <a href="%6$s">%5$s</a>. Bookmark the <a href="%3$s" title="Permalink to %4$s" rel="bookmark">permalink</a>.', 'twentyeleven' );} else {$utility_text = __( 'This entry was posted by <a href="%6$s">%5$s</a>. Bookmark the <a href="%3$s" title="Permalink to %4$s" rel="bookmark">permalink</a>.', 'twentyeleven' );}printf($utility_text,$categories_list,$tag_list,esc_url( get_permalink() ),the_title_attribute( 'echo=0' ),get_the_author(),esc_url( get_author_posts_url( get_the_author_meta( 'ID' ) ) ));?>Display as List Items
By leaving the $separator value empty, it will generate an unordered list instead, complete with classes.
<?php echo get_the_category_list(); ?>
Result:
<ul class="post-categories"><li><a href="http://myblog.com/category/business" title="View all posts in Business" rel="category tag">Business</a></li></ul>
