Get Comma Seperated Taxonomy Linked Terms and Last Child Separated By "&" Instead Of Comma

Question

I Want to List Custom Taxonomy Terms with Link and Separate Each with Comma but add "&" before the last term.

Example:

Drake, Migos, Ciara & Nicki

I found this answer that shows how to add '&' before the last term. BUT the terms are not linked which is what I am trying to achieve.

MY CURRENT CODE:

 $terms = get_the_terms( $post->ID, 'artist' );
            foreach($terms as $index => $term) {
                $enIndex = sizeof($terms) - 2;
    $end = (isset($terms[$enIndex]) && $index == $enIndex ? ' & ' : ', ');
    $entry_terms .= $term->name . $end;
    $term_link = get_term_link( $term );               
            }
            $entry_terms = rtrim( $entry_terms, ', ' );
                                       
 echo '<a href="' . esc_url( $term_link ) . '">' . $entry_terms . '</a>';           

CURRENT RESULT OF MY CODE:

Drake, Migos, Ciara & Nicki

My code is not working fine. It links all terms to the last term link only. Please help check my code. I am new WordPress development. Thanks.

Answer 1

What you're asking is a generic PHP/programming question, and this: "It links all terms to the last term link only", is because your code clearly is attaching the link (i.e. the last value assigned to $term_link) to the entire list ($entry_terms), i.e. echo '<a href="' . esc_url( $term_link ) . '">' . $entry_terms . '</a>'.

So what you should have done is, attach the link to the term name on this line: $entry_terms .= $term->name . $end;, like so:

1. Replace this part:

   $entry_terms .= $term->name . $end;
   $term_link = get_term_link( $term );
   

   with this:

   $term_link = get_term_link( $term );
   $entry_terms .= '<a href="' . esc_url( $term_link ) . '">' . $term->name . '</a>' . $end;
   

And then, after that:

1. Replace the $entry_terms = rtrim( $entry_terms, ', ' ); with echo rtrim( $entry_terms, ', ' );.

2. Remove the echo '<a href="' . esc_url( $term_link ) . '">' . $entry_terms . '</a>';.

Additional Notes

1. You should define $entry_terms before the foreach line, i.e. add $entry_terms = '';.

2. The ampersand sign is being displayed to the user, hence you need to escape the character, i.e. use ' & ' instead on line 4 in your original code.
