Question

我创建了一个具有自己类别的自定义帖子类型。我想将自定义帖子类型的类别链接到WooCommerce产品。例如该产品属于织物盖类别。我在后端的Woocommerce产品中显示了这些类别。我用getterm做到这一点。到目前为止，一切正常。然后，我在每个类别的前面创建了一个复选框字段。当我保存内容时，所有类别都存储在数组中（无论是否选择）。我只想保存我选择的类别。我在做什么错了？

Example

如何将所选复选框的数组保存在metabox（pro_in_cat_fields）中。目前，所有值均已保存。如果仅选中一个复选框（例如，fabric cover1），则仅需要保存该复选框的同一数组中的值。不是布料1，布料2，...等的值

    <?php
add_action('admin_init', 'add_pro_in_cat_boxes', 1);
function add_pro_in_cat_boxes() {
  add_meta_box( 'pro_in_cat-fields', 'Save product in custom category', 'pro_in_cat_meta_box_display', 'product', 'normal', 'low');
 }
    function pro_in_cat_meta_box_display() {
      global $post;
      $pro_in_cat_fields = get_post_meta($post->ID, 'pro_in_cat_fields', true);
      wp_nonce_field( 'pro_in_cat_meta_box_nonce', 'pro_in_cat_meta_box_nonce' );
