loop through posts and get the list of all terms for a taxonomy

  • Im within taxonomies (a) archive and I want to loop through all the posts and retrieve a list of terms for taxonomy (b) then echo that list out with no duplicates. Forgive me as I am new to wordpress and php but here’s what I have so far in my taxonomy.php.

    <?php while (have_posts()) : the_post();
    $terms = get_the_term_list( $post->ID, ‘role-type’, ‘ Role(s): ‘, ‘ ‘, ‘ ‘ );
    echo $terms;
    endwhile; ?>

    Lets say there are three posts in the archive this then displays the following

    Role(s): DOS FE RSM RSS Role(s): DOS FE SPMs RSS Role(s): CSO

    What it should do is display something similar to: Role(s): DOS FE RSM RSS SPMS CSO

    What do I need to do? Thanks for your help

  • I can’t entirely test this, but it should be close:

    <?php $all_terms = '';
$sep = '|';
$taxonomy = 'role-type';
while (have_posts()) : the_post();
    $terms = get_the_term_list( $post-ID, $taxonomy, '', $sep, $sep );
    $all_terms .=  $terms;
endwhile;
$terms_array = explode($sep, $all_terms);
$terms_array = array_unique($terms_array);
$all_terms = implode(' ', $terms_array);
echo "<p>Roles: $all_terms</p>";
?>

    That worked modified it a little bit. 

    <?php $array_out = array();
while (have_posts()) : the_post();
    $terms = get_the_terms( $post->ID, 'role-type');
    foreach($terms as $term){
        $term_link = get_term_link($term, 'role-type');
        $array_out[] = '<a href="'.$term_link.'">'.$term->name.'</a>';
    }
endwhile;

$array_clean = array_unique($array_out);
echo ' ' . implode(', ', $array_clean) . '</p>'; } ?>

    Now how would one do that same thing but create a list of all the posts hierarchical terms list of another different taxonomy? So loop through all posts and spit out

    Parent (a)
    -Children
    Parent (b)
    -Children

    For a taxonomy but with no duplicates.

    Heres what I have so far 

    <?php
 $array_out = array();
 while (have_posts()) : the_post();
$taxonomy = 'workflow-type'; // change this to your taxonomy
$terms = wp_get_post_terms( $post->ID, $taxonomy, array( "fields" => "ids" ) );
if( $terms ) {
  echo '<ul>';

  $terms = trim( implode( ',', (array) $terms ), ' ,' );
  wp_list_categories( 'title_li=&taxonomy=' . $taxonomy . '&include=' . $terms );

  echo '</ul>';
}
endwhile;
?>

    But it doesnt filter out duplicates and diplays something like this:

    Parent (a)
    – Child
    Parent (a)
    – Child
    Parent (b)
    – Child
    Parent (a)
    – Child
