I’ve defined a custom post type for “person”, and I’d like to append class names to the output markup based on taxonomies that correspond to team names. For example, if a person is part of the “creative” and “interactive” teams, I’d like to output the following:
<div class="person creative interactive">Jane</div>
I found this thread on the forum, but in my case I need to output the taxonomy names within an echo
statement, as the output is defined as a function in my functions.php
file.
Here is a reduced version of what I’ve come up with so far, based on the aforementioned thread and this Stack Overflow thread:
function display_all_people() {
// set up arguments for new post query
$args = array(
'post_type' => 'people',
'order' => 'ASC',
'orderby' => 'meta_value',
'meta_key' => 'last_name'
);
$peoplePosts = new WP_Query( $args );
if ( $peoplePosts->have_posts() ) {
echo '<div class="people-listing">';
while ( $peoplePosts->have_posts() ) {
$peoplePosts->the_post();
$terms = get_the_terms( $post->ID, 'teams' );
foreach ($terms as $term) {
echo '<div class="person' . implode('', $term->slug) . '">';
}
echo '<div>More markup for each person listing</div>';
echo '</div>';
}
echo '</div>';
} else {
return '<p>Nothing Here.</p>';
}
wp_reset_postdata();
}
Thus, I’m trying to use the implode()
to concatenate the values of the array (i.e. “team” taxonomy names), but it doesn’t seem to be working (PHP is throwing errors.) Any idea how I can successfully append the taxonomies as class names in this way? Thanks for any assistance here.

Differ the output until you have a collection ready.
$terms = get_the_terms( $post->ID, 'teams' );
// create a collection with your default item
$classes = array('person');
foreach ($terms as $term) {
// add items
$classes[] = $term->slug;
}
// output all the classes together with a space to separate them.
echo '<div class="' . implode(' ', $classes) . '">';
echo '<div>More markup for each person listing</div>';
EXCLUDING
To ignore adding any item:
if( $term->slug !== 'accounting' ) { $classes[] = $term->slug; }
To remove all bad apples:
$pros = array('A', 'B', 'C');
$cons = array('C');
$best = array_diff($pros, $cons);
print_r ($best); // A, B
In context:
$terms = get_the_terms( $post->ID, 'teams' );
// create a collection with your default item
$classes = array( 'person' );
if ( $terms && ! is_wp_error( $terms ) ) {
foreach ( $terms as $term ) {
$classes[] = $term->slug; // add items
}
}
// remove any specific classes here
$classes = array_diff( $classes, array( 'creative-services' ) );
// output all the classes together with a space to separate them.
echo '<div class="' . implode( ' ', $classes ) . '">';
echo '<div>More markup for each person listing</div>';
