WordPress/WooCommerce 代码失效问题：新增产品判断后user_meta无法写入

原本实现了用户购买特定订阅产品（ID：18899）后，通过更新user_meta赋予私有内容访问权限的功能，代码曾正常运行；但添加另一产品（ID：19232）的判断条件后，功能完全失效，数据库中user_meta为空，使用旧版functions.php模板时数据可正常写入，清空缓存仍无法解决问题。

之前正常运行的代码

    // Check the product in the order
    $items = $order->get_items();
    foreach ( $items as $item ) {
        $product_id = $item->get_product_id();
        
        if( $product_id == 18899 ) {

            // Check date user put in form
            $item_meta_data = $item->get_formatted_meta_data( '_', true );
            foreach( $item_meta_data as $the_data ) {
                if( $the_data->key == 'End Date' ) $enddate = $the_data->value;
            }

                }
            }
        }
    }
}

问题诊断与修复方案

核心问题

  1. 函数覆盖导致原有逻辑丢失：新的TB_verify_order_content函数直接替换了旧函数，原产品18899的所有处理逻辑被完全删除
  2. 未定义变量报错：新函数中直接使用$items和$user_id，但没有先获取订单对象并赋值，代码执行时会抛出错误，无法完成user_meta写入
  3. 缺失订单状态判断：去掉了旧代码中$new_status != 'processing'的判断，导致订单状态不符合时也会触发逻辑，容易引发异常

修复后的完整代码

将两个产品的处理逻辑合并，保留原有功能的同时新增19232产品的判断：

// Order check to activate private content
add_action( 'woocommerce_order_status_changed', 'TB_verify_order_content', 10, 3 );
function TB_verify_order_content( $order_id, $old_status, $new_status ) {
    // 仅在订单状态变为processing时执行
    if( $new_status != 'processing' ) return;
    
    $order = wc_get_order( $order_id );
    $user_id = $order->get_user_id();
    
    // 跳过未登录用户的订单
    if ( empty($user_id) ) return;
    
    $items = $order->get_items();
    foreach ( $items as $item ) {
        $product_id = $item->get_product_id();
        
        // 处理原产品18899的逻辑
        if( $product_id == 18899 ) {
            // Check date user put in form
            $item_meta_data = $item->get_formatted_meta_data( '_', true );
            $enddate = '';
            foreach( $item_meta_data as $the_data ) {
                if( $the_data->key == 'End Date' ) $enddate = $the_data->value;
            }
            
            // Check if it's a renew
            $renew = get_post_meta( $order_id, 'is_a_renew', true );
            $is_a_renew = ( isset( $renew ) && $renew == 'yes' ) ? true : false;
            
            if( $enddate != '' ) {
                $first_date = date( 'd/m/Y' );
                
                // Access to private content : setup at first subscription

                        'access_end' => '-1', 
                        'access_end_date' => '', 
                        'end' => $enddate                               
                    );
                    update_user_meta( $user_id, 'BO_access_content', $tab_access );

修复说明

  • 合并了两个产品的处理逻辑，保留原18899的所有功能
  • 修复了未定义变量的问题，先获取订单对象和用户ID
  • 增加了函数存在性判断（function_exists），避免依赖函数缺失导致报错

  • 保留了订单状态判断，确保仅在合适时机执行逻辑
