Taxonomies Shortcode with Links

Here’s a screenshot of the two outputs.

The first shows how I want it but the links aren’t clickable.

The second shows them as clickable but there’s a comma at the end and no “and” before the final term.

Hi @one3rdnerd

I tested this locally but non of these options show a clickable link.

For a clickable link you’d need to following:

[pods][each category]{@name}, [/each][/pods]

Please confirm the shortcode you used for showing clickable links.

Cheers, Jory

Hi Jory,

These are the two I am using (your example is the same as my second one I shared in my last comment) The only difference is you removed talent-type and changed it to category.

[pods]{@talent-type}[/pods].

[pods][each talent-type]{@name}, [/each][/pods]

Please note, this relies on you having the taxonomy “talent-type” so maybe that’s why it didn’t work for you.

My issue is, the first example is formatted perfectly, but I can’t get the terms to be clickable.

The second one creates link, but the formatting is dreadful without commas, so I can’t find a way to use it. Adding comma’s outside of the magic tag means I end up with a comma at the very end, wheras that should be a period like in the first example.

Please advise.

Thanks for your time.

@one3rdnerd The following script can be zipped in a folder and installed as a plugin. It adds a shortcode [talent-category-links], which displays links to taxonomy archive pages using get_term_link(). It expects that the taxonomy terms are associated with the current post using relationship field talent-category for taxonomy talent_category:

<?php
/**
 * Plugin Name: Talent Category Links Shortcode
 * Description: Adds <code>[talent-category-links]</code> shortcode for displaying links to Talent Categories.
 * Version: 1
 * Author: ??δ???
 * Author URI: https://pd.cm/
 */

add_action(
	'plugins_loaded',
	function(){
		add_shortcode(
			'talent-category-links',
			function(){
				$taxonomy = 'talent_category';
				$field_meta_key = 'talent-category';

				// Assumes Pods Admin > Settings > Override WP Metadata values is Disabled:
				// This should return an array of term IDs, not an array of term meta.
				$terms = get_post_meta( get_the_ID(), $field_meta_key, false );

				if ( empty( $terms ) ) {
					return '';
				}

				$term_links = [];
				foreach( $terms as $term_id ) {
					$term = get_term( $term_id, $taxonomy );

					$term_links[] = sprintf(
						'<a href="%s">%s</a>',
						esc_url( get_term_link( $term ) ),
						esc_html( $term->name )
					);
				}

				return sprintf(
					'<p>%s</p>',
					implode( ', ', $term_links )
				);
			}
		);
	}
);

The plugin assumes Pods Admin > Settings > Override WP Metadata values is disabled.

Thanks Paul.

I will give this a test in a moment and let you know how I get on. I will have to change the taxonomy’s underscore to a hyphen so I will do that first.

I appreciate you.

Interesting —?I tried to have them both be talent_category, but when creating the field, it gave me an error. Hope all goes well. Thanks!

Added a small edit for the case in which no terms are assigned.
(If empty, return nothing.)

Hi Paul,

Firstly, thank you very much for your help.

I just gave that a try and updated it to your updated copy.

Unfortunately, nothing is outputting for me, but maybe that’s due to the taxonomy and field meta key being the same.

I checked the settings, and I have Override WP Metadata values disabled.

I changed the field key to be unique, so it’s now $field_meta_key = ‘talent-category-key’; but still nothing shows.

I’m definitely using this on a page where terms are assigned because this is actually part of a migration from using Types Toolset (which is why I had to keep the taxonomy ID/slug as it was previously).

Here’s a video to show you what I’m working with.

Also, I will need to create some more copies of this plugin once working, as this is one of a few different taxonomies I need to do the same with. It would be even better if I could modify it so I could put the taxonomy slug in the shortcode rather than having it hard coded because then I could use the same plugin and shortcode for different taxonomies.

Feel free to watch it on 1.5x speed ??

Okay, looks like it’s a core taxonomy connection, not a relationship field, so the function needs to be different. Revising…

Ah, okay, yes, it’s just a standard connection between custom post type and taxonomy rather than using relationships.

Thank you. I will await your update.

Hi @one3rdnerd

This version should work with the Taxonomy Connections tab. The relationship field is then not necessary.

Usage: [term-links taxonomy="talent-category"]

<?php
/**
 * Plugin Name: Term Links Shortcode
 * Description: Adds <code>[term-links taxonomy="talent-category"]</code> shortcode for displaying links to taxonomy term archives.
 * Version: 2
 * Author: ??δ???
 * Author URI: https://pd.cm/
 */

add_action(
	'plugins_loaded',
	function(){
		add_shortcode(
			'term-links',
			function( $atts ){

				if ( empty( $atts['taxonomy'] ) ) {
					return '<p>Please specify a taxonomy with <code>taxonomy="talent-category"</code>.</p>';
				}

				$terms = wp_get_object_terms( get_the_ID(), $atts['taxonomy'] );

				if ( empty( $terms ) ) {
					return '';
				}

				$term_links = [];
				foreach( $terms as $term ) {
					$term_links[] = sprintf(
						'<a href="%s">%s</a>',
						esc_url( get_term_link( $term ) ),
						esc_html( $term->name )
					);
				}

				return sprintf(
					'<p>%s</p>',
					implode( ', ', $term_links )
				);
			}
		);
	}
);

Thank you Paul.

That one works now and works for my other taxonomy.

Only improvement I can see.

It removes the final comma which is great and I managed to edit it so it includes a full stop/period after the final term but is there a way I can get “and ” to show before the final term.

I tried with the below and the period works but the and ends up at the very start of the entire output.

return sprintf(
	'<p>and %s.</p>',
	implode( ', ', $term_links )

I’m sure this shortcode plugin will be very useful for people, myself included on other sites.

Thanks again.
