WordPress的/ WooCommerce - 相关产品按属性

Question

我知道我不是第一个，我可能不会是最后尝试使这个旅程工作。我已经看过那里的一切。

大多数答案都是WC 2.1前的版本。

许多答复与tax_query一起使用。每隔一段时间，有人试图触摸查询。我试过两种，两种都不适合我。

如何调整WooCommerce中显示的相关产品以通过自定义属性包含关系？

目标：通过猫的关系，

测试通过woocommerce_product_related_posts_query（品牌或艺术家或制造商）：

function product_related_posts_relate_by_attributes ($query){ 
    global $product; 

    //* 
    $brands_array  = wc_get_product_terms($product->id, 'pa_brand', array('fields' => 'ids')); 
    $artists_array  = wc_get_product_terms($product->id, 'pa_artist', array('fields' => 'ids')); 
    $manufacturers_array = wc_get_product_terms($product->id, 'pa_manufacturer', array('fields' => 'ids')); 

    $query['where'] .= ' AND (';   
     $query['where'] .= " (tt.taxonomy = 'pa_brand' AND t.term_id IN (" . implode(',', $brands_array) . ")) ";  
     $query['where'] .= ' OR '; 
     $query['where'] .= " (tt.taxonomy = 'pa_artist' AND t.term_id IN (" . implode(',', $artists_array) . ")) ";  
     $query['where'] .= ' OR '; 
     $query['where'] .= " (tt.taxonomy = 'pa_manufacturer' AND t.term_id IN (" . implode(',', $manufacturers_array) . ")) ";  
    $query['where'] .= ')';//*/ 

    return $query; 
} 
add_filter('woocommerce_product_related_posts_query', 'product_related_posts_relate_by_attributes'); 

测试通过woocommerce_related_products_args：

function custom_related_product_args ($args){ 
    global $product; 

    $cats   = wc_get_product_terms($product->id, 'product_cat', array('fields' => 'slug')); 
    $brands  = wc_get_product_terms($product->id, 'pa_brand', array('fields' => 'slug')); 
    $artists  = wc_get_product_terms($product->id, 'pa_artist', array('fields' => 'slug'));  
    $manufacturers = wc_get_product_terms($product->id, 'pa_manufacturer', array('fields' => 'slug')); 

    unset($args['post__in']); 
    $args['tax_query'] = array( 
     'relation' => 'AND', 
     array(
      'taxonomy' => 'category', 
      'field' => 'slug', 
      'terms' => $cats, 
     ), 
     array(
      'relation' => 'OR', 
      array(
       'taxonomy' => 'pa_brand', 
       'field' => 'slug', 
       'terms' => $brands, 
      ), 
      array(
       'taxonomy' => 'pa_artist', 
       'field' => 'slug', 
       'terms' => $artists, 
      ), 
      array(
       'taxonomy' => 'pa_manufacturer', 
       'field' => 'slug', 
       'terms' => $manufacturers, 
      ) 
     ) 
    ); 

    return $args; 
} 
add_filter('woocommerce_related_products_args', 'custom_related_product_args'); 

可能有人请如此亲切地告诉我我要去哪里错了？

非常感谢您提前！

我尝试了“通过woocommerce_related_products_args测试”，看来你应该只改变“塞”到“鼻涕虫”也“类别”到“product_cat” :)

global $product; 

$cats   = wc_get_product_terms($product->id, 'product_cat', array('fields' => 'slugs')); 
$brands  = wc_get_product_terms($product->id, 'pa_brand', array('fields' => 'slugs')); 
$artists  = wc_get_product_terms($product->id, 'pa_artist', array('fields' => 'slugs'));  
$manufacturers = wc_get_product_terms($product->id, 'pa_manufacturer', array('fields' => 'slugs')); 

unset($args['post__in']); 
$args['tax_query'] = array( 
    'relation' => 'AND', 
    array(
     'taxonomy' => 'product_cat', 
     'field' => 'slug', 
     'terms' => $cats, 
    ), 
    array(
     'relation' => 'OR', 
     array(
      'taxonomy' => 'pa_brand', 
      'field' => 'slug', 
      'terms' => $brands, 
     ), 
     array(
      'taxonomy' => 'pa_artist', 
      'field' => 'slug', 
      'terms' => $artists, 
     ), 
     array(
      'taxonomy' => 'pa_manufacturer', 
      'field' => 'slug', 
      'terms' => $manufacturers, 
     ) 
    ) 
); 

return $args;
