如何在wordpress中使用sql将自定义textarea输入值添加到自定义表？

Question

我正在尝试在创建订单时将自定义文本区域输入写入自定义 WordPress 表中。不幸的是，自定义文本区域输入未保存在我的自定义表中。只有一个“;”存储在我的自定义表的表列“cardcontent”中。我尝试使用 $_POST 访问我的自定义文本区域输入。我认为这是我的错误。

这是我当前在functions.php中的代码：

//triggers before checkout form is submited but order will be created.
add_action( 'woocommerce_checkout_update_order_meta', 'cpm_woocommerce_checkout_update', 10, 2 );

function cpm_woocommerce_checkout_update($order_id, $data) {
        //trying to get my textarea input values with $_POST
    $cardHeading = $_POST['heading'];
    $cardBody = $_POST['bodytext']; 
    
    $order = wc_get_order( $order_id );
        
    if (is_user_logged_in()) {  //check if user is logged in.
        
        global $current_user;
        global $wpdb;
        
                // get current user info
                get_currentuserinfo();
            
        $card = $cardHeading . ";" . $cardBody;
        $timestamp = time();
        $id = $current_user->ID;
        
        // "$wpdb->prefix" will prepend your table prefix
        $table_name =  $wpdb->prefix."cards";

        $data = array( 
            'userid' => $id,
            'orderid' => $order_id,
            'cardcontent' => $card,
            'timestamp' => $timestamp,
        );
        $wpdb->insert( $table_name, $data );
    }
}```

Do i have to attach them to the order first and then apply them to the order in the action?

Thanks in advance

确保表单字段的名称（标题和正文）与您尝试在结帐页面上访问的 $_POST 值匹配。
