سلام دوست عزیز،
2 راهکار دارید:
از این پلاگین استفاده کنید که به شما اجازه میده برای هر محصول محصولات مرتبط مشخصی اضافه کنید:
https://wordpress.org/plugins/wt-woocommerce-related-products/
یا این کد رو به functions.php قالب فعالتون اضافه کنید و تست کنید:
// Get Related Products from SAME Sub-category
add_filter( 'woocommerce_product_related_posts', 'my_custom_related_products' );
function custom_related_products($product){
global $woocommerce;
// Related products are found from category and tag
$tags_array = array(0);
$cats_array = array(0);
// Get tags
$terms = wp_get_post_terms($product->id, 'product_tag');
foreach ( $terms as $term ) $tags_array[] = $term->term_id;
// Get categories
$terms = wp_get_post_terms($product->id, 'product_cat');
foreach ( $terms as $key => $term ){
$check_for_children = get_categories(array('parent' => $term->term_id, 'taxonomy' => 'product_cat'));
if(empty($check_for_children)){
$cats_array[] = $term->term_id;
}
}
// Don't bother if none are set
if ( sizeof($cats_array)==1 && sizeof($tags_array)==1 ) return array();
// Meta query
$meta_query = array();
$meta_query[] = $woocommerce->query->visibility_meta_query();
$meta_query[] = $woocommerce->query->stock_status_meta_query();
$meta_query = array_filter( $meta_query );
// Get the posts
$related_posts = get_posts( array(
'orderby' => 'rand',
'posts_per_page' => $limit,
'post_type' => 'product',
'fields' => 'ids',
'meta_query' => $meta_query,
'tax_query' => array(
'relation' => 'OR',
array(
'taxonomy' => 'product_cat',
'field' => 'id',
'terms' => $cats_array
),
array(
'taxonomy' => 'product_tag',
'field' => 'id',
'terms' => $tags_array
)
)
) );
$related_posts = array_diff( $related_posts, array( $product->id ), $product->get_upsells() );
return $related_posts;
}
