    The difference between this function and get_the_terms() is that this function’s results are not cached (thus, it’ll hit the database every time its called).

    Get term category to only run function if the post (CPT) has that category:

     * Get category and add text to that page, only.
     * @param  string $terms Get post terms
     * @return string        Text
    function wpdocs_additional_measurements() {
         global $post;
        $innertext = "Hemmed tarps have seatbelt material woven into the hems.";
        $terms = wp_get_post_terms( $post->ID, 'product_cat' );
        foreach ( $terms as $term ) {
            $categories[] = $term->slug;
        // Look for term/category by slug	
        if ( in_array( 'custom-tarps', $categories ) ) {
