[英]Display WooCommerce related products based on specific product attribute value
I am trying to get displayed related products based on specific product attribute "pa_kolekcja" term value (set on the product).我正在尝试根据特定产品属性“pa_kolekcja”术语值(在产品上设置)显示相关产品。 I have a following piece of code (it's almost ready) :
我有以下一段代码(几乎准备好了) :
function woo_related_products_edit() {
global $product;
$current_kolekcja = "???"; // <== HERE
$args = apply_filters( 'woocommerce_related_products_args', array(
'post_type' => 'product',
'ignore_sticky_posts' => 1,
'no_found_rows' => 1,
'posts_per_page' => 4,
'orderby' => $orderby,
'post__not_in' => array( $product->id ),
'tax_query' => array(
array(
'taxonomy' => 'pa_kolekcja',
'field' => 'slug',
'terms' => $current_kolekcja
)
)
) );
}
add_filter( 'woocommerce_related_products_args', 'woo_related_products_edit' );
How I can get the current product attribute "pa_kolekcja" term value set on the product?如何获取产品上设置的当前产品属性“pa_kolekcja”术语值?
Update更新
Since woocommerce 3, woocommerce_related_products_args
has been removed.自 woocommerce 3 起,
woocommerce_related_products_args
已被删除。
To display related products for a specific product attribute set in current product, try instead the following:要显示当前产品中特定产品属性集的相关产品,请尝试以下操作:
add_filter( 'woocommerce_related_products', 'related_products_by_attribute', 10, 3 );
function related_products_by_attribute( $related_posts, $product_id, $args ) {
$taxonomy = 'pa_kolekcja'; // HERE define the targeted product attribute taxonomy
$term_slugs = wp_get_post_terms( $product_id, $taxonomy, ['fields' => 'slugs'] ); // Get terms for the product
if ( empty($term_slugs) )
return $related_posts;
$posts_ids = get_posts( array(
'post_type' => 'product',
'ignore_sticky_posts' => 1,
'posts_per_page' => 4,
'post__not_in' => array( $product_id ),
'tax_query' => array( array(
'taxonomy' => $taxonomy,
'field' => 'slug',
'terms' => $term_slugs,
) ),
'fields' => 'ids',
'orderby' => 'rand',
) );
return count($posts_ids) > 0 ? $posts_ids : $related_posts;
}
Code goes in functions.php file of the active child theme (or active theme).代码进入活动子主题(或活动主题)的functions.php文件。 Tested and work.
测试和工作。
