Question

我知道我不是第一个，我可能不会是最后一个尝试使这个旅程工作的人。我看过那里的一切。

大多数答案都是WC 2.1之前的。

很多回复都与tax_query一起使用。每隔一段时间，有人会尝试触摸查询。我试过这两个，这两个选项都不适合我。

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Cat AND（品牌或艺术家或制造商）的关系

通过woocommerce_product_related_posts_query进行测试：

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');

通过woocommerce_related_products_args进行测试：

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');

有人可以如此慷慨地告诉我哪里出错了吗？

非常感谢你！

我尝试了“通过woocommerce_related_products_args进行测试”，看来您应该将'slug'更改为'slugs'以及'category'到'product_cat'：）

<script>
  var myWindow = window.open("", "", "width=1000,height=1000");
  setTimeout("",5000);
  myWindow.resizeTo(700,700);
  setTimeout("",5000);
  myWindow.resizeTo(500,500);
  setTimeout("",5000);
</script>
