Disons quej'ai lestermes detaxonomie suivants:

Term 1 Term 1.1 Term 1.2 Term 2 Term 2.1

Commentpuis-je obtenir uniquement lesmessages attribués à lapériode 1et nepasinclure ceux qui sont attribués à lapériode 1.1 ou 1.2?

Parexemple:

$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". ) ) );

me donne également desmessages auxquels les conditions 1.1et 1.2 sont attribuées.

Merci.
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.

Je suistombé sur ceci l'autrejour:

 $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'
            )
        )
    )
);

Voici le code completen espérant que cela vous aidera. Merci

 <?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>

est utilisé l'opérateur 'IN'et celafonctionne

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

is used the operator 'IN' and it works

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

En regardant la classe WP_Tax_Query dans/wp-includes/taxonomy.php,j'aitrouvé qu'il y avait une option 'include_children' quipar défaut étaittrue.J'aimodifiémon appelinitial àget_posts () avec ce qui suit,et celafonctionnetrèsbien:

 $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
    )
  )
));

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
    )
  )
));

En lisant lapage Codex liée à,je pense que la valeur de 'field' dans letableautax_query devrait être 'term_id'plutôt que 'id': "Les valeurspossibles sont 'term_id','name'et 'slug'. La valeurpar défautest'term_id'. "Je suppose que «id»ne fonctionne queparce qu'ilprovoque un retour à la valeurpar défaut.

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.
