get_the_terms Ordering

  • I am using the Salient wordpress theme which we are trying to re-use its ‘Project Attributes’ list.

    This is the code that outputs our list for each portfolio item: 

    <?php
	$project_attrs = get_the_terms( $post->ID, 'project-attributes' );
	if (!empty($project_attrs)){ ?>
		<div data-color="accent-color" data-animation="true" data-list-icon="icon-angle-right" class="nectar-fancy-ul">
			<ul>
				<?php
					foreach($project_attrs as $attr){
						echo '<li>' . $attr->name . '</li>';
					}
				?>
			</ul>
		</div>
<?php } ?>

    Essentially we would like it to be listed hierarchically instead of A-Z but everything I try fails.

    Any help would be appreciated.

    Thanks heaps.

  • I could not test this exactly, but the code here works when I use $project_attrs = get_terms('category');

    <?php
   $project_attrs = get_the_terms( $post->ID, 'project-attributes' );
   if (!empty($project_attrs)){
      $parents = array();
      foreach ($project_attrs as $term) {
         if ($term->parent <> 0) ++$parents[$term->parent]; // Identify all parents
      }
      ?>
      <div data-color="accent-color" data-animation="true" data-list-icon="icon-angle-right" class="nectar-fancy-ul">
         <?php $op = '<ul>';
               foreach($project_attrs as $attr){
                  if ($attr->parent == 0) {
                     $op .= '<li>' . $attr->name . '</li>';
                     if (array_key_exists($attr->term_id, $parents)) {
                        add_term_children($attr->term_id, $depth=0, $op, $project_attrs, $parents);
                     }
                  }
               }
         $op .= '</ul>';
         echo $op; ?>
      </div>
<?php }

function add_term_children($parent_id, $depth, &$op, $project_attrs, &$parents) {
   ++$depth;
   $sep = str_repeat(' -', $depth);
   foreach ($project_attrs as $attr) {
      if ($attr->parent == $parent_id) {
         $op .= '<li>' . "$sep $attr->name" . '</li>';
         if (array_key_exists($attr->term_id, $parents)) {
            add_term_children($attr->term_id, $depth, $op, $project_attrs, $parents);
         }
      }
   }
}

?>
