list custom post type by taxonomy

Hi osby here is the code I used:

$post_type = 'post_type_name';
$tax = 'taxonomy_name';
$tax_terms = get_terms($tax);
if ($tax_terms) {
  foreach ($tax_terms  as $tax_term) {
    $args=array(
      'post_type' => $post_type,
      "$tax" => $tax_term->slug,
      'post_status' => 'publish',
      'posts_per_page' => -1,
      'caller_get_posts'=> 1
    );

    $my_query = null;
    $my_query = new WP_Query($args);
    if( $my_query->have_posts() ) {
      echo '<h3 class="divisions">'. $tax_term->name . '</h3>';
	  echo '<ul class="team-members">';
      while ($my_query->have_posts()) : $my_query->the_post(); ?>
         <li>
         <h4 class="team-member"><?php the_title(); ?></h4>
         <?php if(has_post_thumbnail()) { ?>
        <span class="alignleft"><?php the_post_thumbnail(); ?></span>
        <?php } the_content(); ?>
        </li>
        <?php
      endwhile;
	  echo '</ul>';
    }
    wp_reset_query();
  }
}

I hope this helps 🙂
