In order to assign post_tags and custom_taxonomies from a post to a class, this is what I've been trying to do.

$terms = get_the_terms( $post->ID, array( 'post_tag', 'custom' );

if ( $terms ) {
    foreach ( $terms as $term ) {
        $termString .= $term->slug . ' ';
    }
}

<div class="taxonomies here">content</div>

For some reason this doesn´t work, seems like get_the_terms does not support arrays for multiple taxonomies. How can this be worked around?

Thanks.

Anyway, I came across this from another question:

$terms = wp_get_object_terms( $post_id, get_object_taxonomies('post') );

and it works.
