WordPress的/ WooCommerce - 相關產品按屬性

Question

我知道我不是第一個，我可能不會是最後嘗試使這個旅程工作。我已經看過那裏的一切。

大多數答案都是WC 2.1前的版本。

許多答覆與tax_query一起使用。每隔一段時間，有人試圖觸摸查詢。我試過兩種，兩種都不適合我。

如何調整WooCommerce中顯示的相關產品以通過自定義屬性包含關係？

測試通過woocommerce_product_related_posts_query（品牌或藝術家或製造商）：

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'); 

測試通過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'); 

可能有人請如此親切地告訴我我要去哪裏錯了？

非常感謝您提前！

我嘗試了「通過woocommerce_related_products_args測試」，看來你應該只改變「塞」到「鼻涕蟲」也「類別」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;
