我正在为通过自定义帖子类型on a website创建的某些产品开发过滤系统，这些产品具有自定义分类。它们分为两个部分，市场和功能。如果单击第一部分中的对象，则会将其添加到用于$ _POST ['taxonomy']的数组中。另一部分添加到同一个数组中，因此我尝试使用array_intersect()将结果划分为两个数组，因为我之后使用tax_query和'relation' => 'AND'。< / p>
这两个tax_queries基于这两个部分，市场和功能。
我得到的结果总是添加每一件产品（共96件）。我正在使用AJAX来实现下面的功能。 （使用的JS只是处理结果并且正在怀疑，所以我确定下面的PHP有问题。）
function largo_filter() {
// The array of the selected taxonomies on the product search page
$taxonomy = json_decode(stripslashes($_POST['taxonomy']));
// These are the two sections, market and filter, divided into two arrays (the taxonomies actually have an ACF field called 'area' which I want to base them on, automatically, but haven't figured that out yet)
$market_array = array('butik', 'design', 'farg-lack', 'fordon', 'grafisk produktion', 'lakemedel', 'livsmedel', 'plast', 'textil');
$filter_array = array('doseringssystem', 'glansmatning', 'kulormatning', 'labbutrustning', 'programvaror', 'skak-mix', 'skikttjocklek', 'visuell-bedomning');
// Match which taxonomies from the search results are equal to the ones in the two sections
$market_match = array_intersect( $market_array, $taxonomy );
$filter_match = array_intersect( $filter_array, $taxonomy );
// Get all custom taxonomies called 'products_category' (that's ANOTHER custom taxonomy I'm using, to divide the search results into different parts (they each have a headline, shown in the search results on the website)
$terms = get_terms(
array(
'taxonomy' => 'products_category',
'hide_empty' => true,
)
);
$num_posts = 0;
// Loop through every term
foreach( $terms as $term ) {
$args = array(
'posts_per_page' => -1,
'post_type' => 'produkt',
'products_category' => $term->slug,
'orderby' => 'title',
'order' => 'ASC',
// I want the products showing to have any of the terms from the market section AND any of the terms in the function section to be the results
