Tag Cloud Shortcode

  • Hey guys, I tried creating a custom tag cloud shortcode, but it’s not showing the tags on the front of my site. Here’s the code I’m dropping into my functions.php file:

    function wpb_tag_cloud() { 
$tags = get_tags();
$args = array(
    'smallest'                  => 10, 
    'largest'                   => 22,
    'unit'                      => 'px', 
    'number'                    => 10,  
    'format'                    => 'flat',
    'separator'                 => " ",
    'orderby'                   => 'count', 
    'order'                     => 'DESC',
    'show_count'                => 1,
    'echo'                      => false
); 
 
$tag_string = wp_generate_tag_cloud( $tags, $args );
 
return $tag_string; 
 
} 
// Add a shortcode so that we can use it in widgets, posts, and pages
add_shortcode('wpb_popular_tags', 'wpb_tag_cloud'); 
 
// Enable shortcode execution in text widget
add_filter ('widget_text', 'do_shortcode');

  • Hello Matt!

    I have tried the code you provided, and it works as expected. Please make sure you already have tags in your website.

    Don’t forget to copy the [wpb_popular_tags] shortcode in the place when you want to show the cloud of tags. You can past it on any page in your website or in a text widget from your dashboard in Appearance >> Widgets.

    Please try this and let me know if all is fine and working now. ??

    Hmmm very strange! Well thanks for letting me know it’s working on your end. It must be something to do with my theme maybe? I have two custom taxonomies and I know I’m using the right ones. Is there any way to debug it to see where the problem might be?

    Actually you know what, I don’t think the function wp_generate_tag_cloud allows for a custom taxonomy. So how would I edit the code to only pull tags from a specific taxonomy?

    Nevermind, I think I figured out a solution but using this code instead:

    function my_cloud() {
    if (function_exists('wp_tag_cloud'))
        return wp_tag_cloud(array(
        	'smallest'                  => 9, 
		'largest'                   => 20,
		'unit'                      => 'pt', 
		'number'                    => 10,  
		'format'                    => 'list',
		'separator'                 => "\n",
		'orderby'                   => 'name', 
		'order'                     => 'ASC',
		'link'                      => 'view', 
		'taxonomy'                  => '',
		'show_count'                => 0,
        ));
}
add_shortcode('popular_tags', 'my_cloud');

    Nice! One thing though, wp_tag_cloud() echoes by default. Add 'echo'=> false, to your arguments array.

    I’m assuming you will also add a taxonomy value for your custom taxonomy.

    I don’t really understand the whole echo thing lol. I went ahead and added it to my arguments array, but it didn’t seem to change anything. What does it do that I’m not seeing? Yeah, I have a taxonomy, but I just removed it for the sake of this thread ??

    Thanks @bcworks!

    When we echo from a shortcode handler, we cannot predict where the output will occur. It’s often not where the shortcode was placed. In your case it sounds like it didn’t make any difference, a fortunate happenstance. In any case, it’s a firm rule that shortcode handlers must return the desired output and not echo out. Something to keep in mind for your next shortcode ??
