Display List of Tags

This tutorial provides 5 different code examples which enable you to display a list of tags anywhere in your theme.

In the 1st example, the code displays the list using the loop start hook and includes the count.

add_action( 'loop_start', 'list_tags_with_count' );
function list_tags_with_count() {
$tags = get_tags( array('orderby' => 'count', 'order' => 'DESC') );
foreach ( (array) $tags as $tag ) {
echo '<li><a href="' . get_tag_link ($tag->term_id) . '" rel="tag">' . $tag->name . ' (' . $tag->count . ') </a></li>';
    }
}

The 2nd example removes the tag count:

add_action( 'loop_start', 'list_tags_no_count' );
function list_tags_no_count() {
$tags = get_tags( array('orderby' => 'count', 'order' => 'DESC') );
foreach ( (array) $tags as $tag ) {
echo '<li><a href="' . get_tag_link ($tag->term_id) . '" rel="tag">' . $tag->name . '</a></li>';
    }
}

The 3rd example adds a custom class to each listed tag:

add_action( 'loop_start', 'list_tags_with_class' );
function list_tags_with_class() {
$tags = get_tags();
$html = '<ul class="post_tags">';
foreach ( $tags as $tag ) {
	$tag_link = get_tag_link( $tag->term_id );
			
	$html .= "<li><a href='{$tag_link}' title='{$tag->name} Tag' class='{$tag->slug}'>";
	$html .= "{$tag->name}</a></li>";
    }
$html .= '</ul>';
echo $html;
}

The 4th example works on single posts and displays tags for each post in a list.

add_action('loop_start','list_single_post_tags');
function list_single_post_tags() {
if ( is_singular('post')) {
    echo get_the_tag_list('<ul><li>','</li><li>','</li></ul>');
    }
}

See get_the_tag_list for more information.

Custom Tag List Widget

This code enables you to create your own tag list widget similar to the native tag cloud widget included in WordPress.

You’ll need to load the file from your functions file and register the widget using the following code.

In this example, we’ll load the file from a child theme using get_stylesheet_directory()

require_once( get_stylesheet_directory() . '/class-wp-widget-tag-list.php' );

function register_tag_lists_widget() {
	register_widget( 'WP_Widget_Tag_List' );
}
add_action( 'widgets_init', 'register_tag_lists_widget' );

And then create a file named class-wp-widget-tag-list.php in your child themes root directory using the following code.
