[Resolved] Displaying primary category on homepage using shortcode via content template

[Yulia]

Hi, there are similar posts on this topic, but I’m using The SEO Framework (TSF) to manage my primary category.

I’m trying to show a primary category as a clickable link using a shortcode on homepage using content template block.

Below is the shortcode that was provided by @cybr from TSF and it works as intended on regular post pages in GeneratePress.

No information is displayed when used on homepage, not even [shortcode_name].

add_shortcode( 'dynamic_term_link', 'dynamic_term_link_function' );
/**
 * Dynamically fetches the primary term from TSF. 
 * If none is set, or TSF is inactive, it returns the first term found.
 *
 * @return string The primary term link for the current post.
 */
function dynamic_term_link_function() {
    
	if ( ! is_single() ) return;
    
	$post_type = get_post_type();
	$id        = get_the_ID();
	$taxonomy  = current( get_object_taxonomies( $post_type, 'objects' ) )->name ?? false;
	
	if ( ! $taxonomy ) return '';
	
	$primary_term_id = function_exists( 'tsf' ) ? tsf()->get_primary_term( $id, $taxonomy ) : 0;
	$primary_term_id = $primary_term_id ?: ( get_the_terms( get_the_ID(), $taxonomy )[0]->term_id ?? null );

	if ( $primary_term_id ) {
		$term      = get_term( $primary_term_id, $taxonomy );
		$term_link = get_term_link( $term );
		$term_name = $term->name ?? '';
    	
		if ( $term_link && $term_name )
			return sprintf(
				'<a class="gb-headline-text" href="%s">%s</a>',
				esc_url( $term_link ),
				esc_html( $term_name )
			);
	}

	return '';
}

How to make it work on homepage?

Figured it out.
Just need to remove this line if ( ! is_single() ) return;.

Here is the updated shortcode that works anywhere on the website:

add_shortcode( 'dynamic_category_link', 'dynamic_term_link_function' );
/**
 * Dynamically fetches the primary term from TSF. 
 * If none is set, or TSF is inactive, it returns the first term found.
 *
 * @return string The primary term link for the current post.
 */
function dynamic_term_link_function() {
	$post_type = get_post_type();
	$id        = get_the_ID();
	$taxonomy  = current( get_object_taxonomies( $post_type, 'objects' ) )->name ?? false;
	
	if ( ! $taxonomy ) return '';
	
	$primary_term_id = function_exists( 'tsf' ) ? tsf()->get_primary_term( $id, $taxonomy ) : 0;
	$primary_term_id = $primary_term_id ?: ( get_the_terms( get_the_ID(), $taxonomy )[0]->term_id ?? null );

	if ( $primary_term_id ) {
		$term      = get_term( $primary_term_id, $taxonomy );
		$term_link = get_term_link( $term );
		$term_name = $term->name ?? '';
    	
		if ( $term_link && $term_name )
			return sprintf(
				'<a class="gb-headline-text" href="%s">%s</a>',
				esc_url( $term_link ),
				esc_html( $term_name )
			);
	}

	return '';
}

Cheers!
