好的,所以这是我的破解。这有点hacky,但它有效。最大的缺点是需要重新添加任何其他查询变量,因为当调用多个术语时,失败会删除所有查询变量。
此外,我没有针对跨多个分类法的查询进行测试。这仅适用于特定的分类。使用风险自负。
function multi_tax_terms($where) {
global $wp_query;
if ( strpos($wp_query->query_vars['term'], ',') !== false && strpos($where, "AND 0") !== false ) {
// it's failing because taxonomies can't handle multiple terms
//first, get the terms
$term_arr = explode(",", $wp_query->query_vars['term']);
foreach($term_arr as $term_item) {
$terms[] = get_terms($wp_query->query_vars['taxonomy'], array('slug' => $term_item));
}
//next, get the id of posts with that term in that tax
foreach ( $terms as $term ) {
$term_ids[] = $term[0]->term_id;
}
$post_ids = get_objects_in_term($term_ids, $wp_query->query_vars['taxonomy']);
if ( !is_wp_error($post_ids) && count($post_ids) ) {
// build the new query
$new_where = " AND wp_posts.ID IN (" . implode(', ', $post_ids) . ") ";
// re-add any other query vars via concatenation on the $new_where string below here
// now, sub out the bad where with the good
$where = str_replace("AND 0", $new_where, $where);
} else {
// give up
}
}
return $where;
}
add_filter("posts_where", "multi_tax_terms");
