Использование

$WP_Term_Query = new WP_Term_Query();
$WP_Term_Query->__construct( $query );
$query(строка/массив)

Array or query string of term query parameters.

  • taxonomy(строка/массив)
    Taxonomy name, or array of taxonomies, to which results should be limited.

  • object_ids(число/массив)
    Optional. Object ID, or array of object IDs. Results will be limited to terms associated with these objects.

  • orderby(строка)
    Field(s) to order terms by. Accepts:

    • term fields ('name', 'slug', 'term_group', 'term_id', 'id', 'description', 'parent', 'term_order'). Unless $object_ids is not empty, 'term_order' is treated the same as 'term_id'.
    • 'count' for term taxonomy count.
    • 'include' to match the 'order' of the $include param.
    • 'slug__in' to match the 'order' of the $slug param.
    • 'meta_value', 'meta_value_num'.
    • the value of $meta_key.
    • the array keys of $meta_query.
    • 'none' to omit the ORDER BY clause.

По умолчанию: 'name'

  • order(строка)
    Whether to order terms in ascending or descending order. Accepts 'ASC' (ascending) or 'DESC' (descending).

    По умолчанию: empty array

  • exclude_tree(массив/строка)
    Array or comma/space-separated string of term IDs to exclude along with all of their descendant terms. If $include is non-empty, $exclude_tree is ignored.
    По умолчанию: empty array

  • number(число/строка)
    Maximum number of terms to return. Accepts ''|0 (all) or any positive number.|0 (all). Note that $number may not return accurate results when coupled with $object_ids. See #41796 for details.
    По умолчанию: ''

  • offset(число)
    The number by which to offset the terms query.
    По умолчанию: ''

    • 'ids' Returns an array of term IDs (int[]).
    • 'tt_ids' Returns an array of term taxonomy IDs (int[]).
    • 'names' Returns an array of term names (string[]).
    • 'slugs' Returns an array of term slugs (string[]).
    • 'count' Returns the number of matching terms (int).
    • 'id=>parent' Returns an associative array of parent term IDs, keyed by term ID (int[]).

    • 'id=>slug' Returns an associative array of term slugs, keyed by term ID (string[]).
