所以基本上我使用下面的代码似乎将所有内容完美地放入查询中，但是，我仍然得到错误的产品。例如，我要求的产品类别为“冬季”。但仍然接受类别＆＃39;全季节＆＃39;
的产品这是我的代码：
add_action('pre_get_posts', 'advanced_search_query', 1000);
function advanced_search_query($query) {
if ( ! is_admin() && $query->is_main_query() && $query->is_search() ) {
global $wp_query;
// category terms search
$categories = array('winter','all-season','summer','run-flat');
$category = $_GET['category'];
$categories = array_diff($categories,array($category));
$taxonomy = 'product_cat';
if (isset($category) && !empty($category)) {
$args = array(
'relation' => 'AND',
array(
'taxonomy' => $taxonomy,
'field' => 'slug',
'terms' => $category,
'operator' => 'IN'
),
array(
'taxonomy' => $taxonomy,
'field' => 'slug',
'terms' => array($categories),
'operator' => 'NOT IN'
)
);
$query->set('tax_query', $args);
print_r($query);
}
return $query;
}
}
print_r返回以下内容：

答案 0 :(得分：0)
我的猜测是你的tax_query中的条件有一个双数组。你有：
$categories = array('...');
$args = array(
//....
array(
'terms' => array( $categories )
)
//....
);
这应该只是：
'terms' => $categories
