List Multiple Job Types

I had this need for a client and see that others wanted the same so I created these additional functions. Hopefully these can be included in the core.

Add the following to your child theme functions.php:

/**
 * get_the_job_types function.
 */
function get_the_job_types( $post = null ) {
	$post = get_post( $post );
	if ( $post->post_type !== 'job_listing' ) {
		return;
	}
	$types = wp_get_post_terms( $post->ID, 'job_listing_type' );

	return apply_filters( 'the_job_types', $types, $post);
}

/**
 * print_job_types function.
 */
function print_job_types( $post = null ) {
        $types = get_the_job_types( $post );
        foreach( $types as $type ) {
           echo '<li class="job-type '. sanitize_title( $type->slug ).'">'. $type->name.'</li>';
        }
}

create a template override on the content-job_listing.php file and change this line:

<li class="job-type <?php echo get_the_job_type() ? sanitize_title( get_the_job_type()->slug ) : ''; ?>"><?php the_job_type(); ?></li>

to this:

<?php print_job_types(); ?>

You may have to create additional template overrides for the single job details page or if your theme has specific styling overirde already.

Hope this helps.
