问题排查：前端提交产品草稿后WP-admin产品列表无显示

我正在搭建一个页面模板，需要实现以下功能：

将产品提交为Draft（草稿）；
发送邮件给管理员请求审核（将草稿转为发布状态）；
提交成功后跳转至「我的账户」页面。

所有字段均已填写完成，但WP-admin的产品列表中未出现任何产品，烦请帮忙排查问题所在。

核心排查与修复方案

状态变更未保存
调用$new_product->set_status( 'draft' )后，必须执行$new_product->save()才能将状态写入数据库，否则产品不会被正确存储。修改代码：
```
$new_product->set_status( 'draft' );
$new_product->save(); // 新增这一行
wp_safe_redirect( home_url( '/mitt-konto/' ) );
exit();
```
拍卖产品类型依赖验证
代码中指定产品类型为auction，需确认已安装并启用支持拍卖产品的WooCommerce插件（如WooCommerce Simple Auctions）。若无对应插件，wc_create_product会创建失败，且错误提示会被重定向覆盖。
日期转换问题
前端datetime-local输入格式为YYYY-MM-DDTHH:MM，strtotime转换可能失败，可添加日志排查：
```
error_log('转换后开始日期：' . date( 'Y-m-d \a\t H:i:s', strtotime( $starting_sale_date ) ));
```
若转换失败，需调整日期格式化逻辑。
产品列表筛选检查
WP-admin产品列表默认只显示「发布」状态产品，需切换筛选器至「草稿」状态查看是否存在提交的产品。
错误提示被重定向覆盖
当产品创建失败时，echo的错误信息会被重定向的header覆盖，无法显示。可将错误存入session，跳转后展示：
```
if ( is_wp_error( $new_product ) ) {
    $_SESSION['product_error'] = $new_product->get_error_message();
    wp_safe_redirect( home_url( '/create-product/' ) );
    exit();
}
```
然后在页面模板中添加session错误展示逻辑。
描述字段赋值颠倒
代码中description和short_description赋值颠倒，虽不影响创建，但需修正为逻辑正确的写法：
```
'description' => $long_description,
'short_description' => $short_description,
```
