get_postsは、用語の子ではなく、特定のカスタム分類用語に割り当てられます

次の分類用語があるとします:

Term 1 Term 1.1 Term 1.2 Term 2 Term 2.1

用語1に割り当てられている投稿のみを取得し、用語1.1または用語1.2に割り当てられている投稿は含まないようにするにはどうすればよいですか?

例:

$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". ) ) );

用語1.1と1.2が割り当てられた投稿も提供しています.

ありがとうございます.
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.

先日これに出くわしました:

 $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'
            )
        )
    )
);

ここに完全なコードがあります.ありがとう

 <?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

演算子「IN」が使用され、機能します

'分類'=> 'コレクション'、 'terms'=> array(28)、 'フィールド'=> 'id'、 '演算子'=> 'IN'

is used the operator 'IN' and it works

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

/wp-includes/taxonomy.phpのWP_Tax_Queryクラスを見ると、デフォルトでtrueに設定されている「include_children」オプションがあることがわかりました.元のget_posts()呼び出しを次のように変更しましたが、うまく機能します:

 $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
    )
  )
));

その他のクエリパラメータのリスト: 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

リンク先のコーデックスページを読むと、tax_query配列の「field」の値は「id」ではなく「term_id」である必要があると思います.「可能な値は「term_id」、「name」、「slug」です.デフォルト値は「term_id」.」'id'はデフォルトへのフォールバックを引き起こすため、機能するだけだと思います.

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.
