Question

对于woocommerce大师，我有4个产品类别，分别为A，B，C，D，其类别ID为1,2,3,4。

我要实现的目标：

如果选中了产品类别A，则不会自动检查类别B，而不会影响其他类别。
如果未选中产品类别A，则将自动检查类别B，而不会影响其他类别。

基于这篇帖子Automatically assign products to a defined product category in WooCommerce，我编写了这些代码。

// Only on WooCommerce Product edit pages (Admin)
add_action( 'save_post', 'auto_add_product_category', 50, 3 );
function auto_add_product_category( $post_id, $post, $update ) {

if ( $post->post_type != 'product') return; // Only products

// If this is an autosave, our form has not been submitted, so we don't want to do anything.
if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE )
    return $post_id;

// Check the user's permissions.
if ( ! current_user_can( 'edit_product', $post_id ) )
    return $post_id;

$term_id = 2; // <== Your targeted product category term ID
$term_id2 = 1; // <== Your targeted product category term ID
$taxonomy = 'product_cat'; // The taxonomy for Product category

// If the product has not "93" category id and if "93" category exist
if ( ! has_term( $term_id2, 'product_cat', $post_id ) && term_exists( $term_id2, $taxonomy ) )
    wp_set_post_terms( $post_id, $term_id, $taxonomy, true ); // we set this product category
else
    wp_set_post_terms( $post_id, $term_id, $taxonomy, false );
}

数字2可以正常工作，但是对于数字1，会发生这种情况：

如果选中了商品类别A，则类别B和所有其他类别都将取消选中，类别B除外。

有什么想法吗？

尝试一下：

$term_id_A = 1,
$term_id_B = 2;
//get all the terms:
$terms = get_the_terms( $post_id, 'product_cat' );
//just their IDs:
$term_ids = wp_list_pluck( $terms, 'term_id' );

if(in_array($term_id_A, $term_ids) && ($key = array_search($term_id_B, $term_ids)) !== false) {
    unset($term_ids[$key]);
} elseif(!in_array($term_id_A, $term_ids) && !in_array($term_id_B, $term_ids)) {
    $term_ids[] = $term_id_B;
}
wp_set_post_terms($post_id, $term_ids, 'product_cat');

WooCommerce使用If Else语句自动分配产品类别
