Supponiamo cheio abbiai seguentitermini ditassonomia:

 Term 1
  Term 1.1
  Term 1.2
Term 2
  Term 2.1

Comeposso ottenere soloi post assegnati altermine 1e nonincludere quelli assegnati altermine 1.1 o altermine 1.2?

Adesempio:

 $pages = get_posts(array(
  'post_type' => 'page',
  'numberposts' => -1,
  'tax_query' => array(
    array(
      'taxonomy' => 'taxonomy-name',
      'field' => 'id',
      'terms' => 1 // Where term_id of Term 1 is "1".
    )
  )
);

mi offre anchepost a cui sono assegnatii Termini 1.1e 1.2.

Grazie.

Say I have the following taxonomy terms:

Term 1
  Term 1.1
  Term 1.2
Term 2
  Term 2.1

How can I get only posts that are assigned to Term 1 and not include those that are assigned to Term 1.1 or Term 1.2?

For example:

$pages = get_posts(array(
  'post_type' => 'page',
  'numberposts' => -1,
  'tax_query' => array(
    array(
      'taxonomy' => 'taxonomy-name',
      'field' => 'id',
      'terms' => 1 // Where term_id of Term 1 is "1".
    )
  )
);

is also giving me posts that have Terms 1.1 and 1.2 assigned.

Thanks.

ho appena scoperto questo l'altrogiorno:

 $tax = 'music';
$oterm = 'pop';
$term = get_term_by('slug', $oterm, $tax);
$termChildren = get_term_children($term->term_id, $tax);
$wp_query = new WP_Query();
$wp_query->query(
    array(
        'posts_per_page' => '5',
        'tax_query' => array(
            array(
                'taxonomy' => $tax,
                'field' => 'slug',
                'terms' => $oterm
            ),
            array(
                'taxonomy' => $tax,
                'field' => 'id',
                'terms' => $termChildren,
                'operator' => 'NOT IN'
            )
        )
    )
);

just came across this the other day:

$tax = 'music';
$oterm = 'pop';
$term = get_term_by('slug', $oterm, $tax);
$termChildren = get_term_children($term->term_id, $tax);
$wp_query = new WP_Query();
$wp_query->query(
    array(
        'posts_per_page' => '5',
        'tax_query' => array(
            array(
                'taxonomy' => $tax,
                'field' => 'slug',
                'terms' => $oterm
            ),
            array(
                'taxonomy' => $tax,
                'field' => 'id',
                'terms' => $termChildren,
                'operator' => 'NOT IN'
            )
        )
    )
);

Eccoil codice completo che speropossa aiutare. Grazie

 <?php 
$terms_array = array( 
  'taxonomy' => 'services', // you can change it according to your taxonomy
  'parent'   => 0 // If parent => 0 is passed, only top-level terms will be returned
);
$services_terms = get_terms($terms_array); 
foreach($services_terms as $service): ?>
<h4><?php echo $service->name; ?></h4>
<?php 
$post_args = array(
      'posts_per_page' => -1,
      'post_type' => 'service', // you can change it according to your custom post type
      'tax_query' => array(
          array(
              'taxonomy' => 'services', // you can change it according to your taxonomy
              'field' => 'term_id', // this can be 'term_id', 'slug' & 'name'
              'terms' => $service->term_id,
          )
      )
);
$myposts = get_posts($post_args); ?>
<ul>
<?php foreach ( $myposts as $post ) : setup_postdata( $post ); ?>
  <li>
    <a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
  </li>
<?php endforeach; // Term Post foreach ?>
</ul>
<?php wp_reset_postdata(); ?>

<?php endforeach; // End Term foreach; ?>

Here is complete code hope it helps. Thanks

viene utilizzato l'operatore "IN"e funziona

'taxonomy'=> 'collections', 'terms'=> array (28), 'field'=> 'id', "operator"=> "IN"

is used the operator 'IN' and it works

'taxonomy' => 'collections', 'terms' => array( 28 ), 'field' => 'id', 'operator' => 'IN'

Osservando la classe WP_Tax_Queryin/wp-includes/taxonomy.php,ho scoperto cheesiste un'opzione "include_children" cheperimpostazionepredefinita ètrue.Homodificato lamia chiamataget_posts () originale con quanto seguee funziona allagrande:

 $pages = get_posts(array(
  'post_type' => 'page',
  'numberposts' => -1,
  'tax_query' => array(
    array(
      'taxonomy' => 'taxonomy-name',
      'field' => 'term_id', 
      'terms' => 1, /// Where term_id of Term 1 is "1".
      'include_children' => false
    )
  )
));

Elenco di altriparametri di query: http://codex.wordpress.org/Class_Reference/WP_Query#Taxonomy_Parameters

In looking at the WP_Tax_Query class in /wp-includes/taxonomy.php, I found that there is a 'include_children' option which defaults to true. I modified my original get_posts() call with the following, and it works great:

$pages = get_posts(array(
  'post_type' => 'page',
  'numberposts' => -1,
  'tax_query' => array(
    array(
      'taxonomy' => 'taxonomy-name',
      'field' => 'term_id', 
      'terms' => 1, /// Where term_id of Term 1 is "1".
      'include_children' => false
    )
  )
));

List of more query parameters: http://codex.wordpress.org/Class_Reference/WP_Query#Taxonomy_Parameters

Leggendo dallapagina Codex collegata a,penso cheil valore di 'field'nell'arraytax_query dovrebbeessere 'term_id'invece di 'id': "I valoripossibili sono 'term_id','name'e 'slug'. Il valorepredefinito è'term_id'. "Immagino che "id"funzioni soloperché causa unfallback all'impostazionepredefinita.

Reading from the Codex page linked to, I think the value of 'field' in the tax_query array should be 'term_id' rather than 'id': "Possible values are 'term_id', 'name' and 'slug'. Default value is 'term_id'." I'm guessing 'id' only works because it causes a fall-back to the default.
