在Wooccommerce中验证订单更新表单中的用户所有权需要帮助

我目前正在开发一个表单,允许用户更新特定的订单详细信息,包括费用和费用原因。成功更新订单后,表单会显示一个JavaScript警报,更新后的数据会反映在订单的元数据中。但是,我遇到了一个用户所有权验证问题。

以下是我面临的问题:

所有权验证 :我想确保用户只能更新与其用户ID相关的订单,而不能更新属于其他人的订单。目前,当用户输入的订单ID与其帐户无关时,订单元数据不会更新,但仍会触发JavaScript警报,提示更新成功。

我在下面包含了我的代码以供参考:

<form id="expense_form" class="expense_form" action="" method="post">
    <label for="order-id">Order ID:</label>
    <input class="exp_order_no" id="exp_order_no" type="text" pattern="[0-9]*" placeholder="Enter the Order Number" required>
    
    <label for="expense">Expense:</label>
    <input class="expense_amt" id="expense_amt" type="text"  pattern="[0-9]*" placeholder="Enter the expense amount" required>
    
    <label for="reason">Reason for Expense:</label>
    <textarea class="expense_reason" id="expense_reason" id="reason" name="reason" rows="4" placeholder="Enter Message" required></textarea>

    <input type="submit" class="exp_but" id="exp_but" value="Submit">
</form> 
<script>
    jQuery(document).ready(function($) {
            $('#expense_form').on('submit', function(e) {
                e.preventDefault();
                var orderid  = $('#exp_order_no').val();
                var expense  = $('#expense_amt').val();
                var expense_reason  = $('#expense_reason').val();
                    //  console.log (orderid);
                    //  console.log (expense);
                    //  console.log (expense_reason);
             $.ajax({
                    url: '<?php echo admin_url('admin-ajax.php'); ?>',
                    type: 'POST',
                    data: {
                        action:'update_custom_field_order_expense_php',
                        orderid: orderid,
                        expense: expense,
                        expense_reason:expense_reason
                    },
                    success: function( response ) {
                        console.log( 'Custom field updated successfully.' );
                        alert('Expense Submitted Successfully !!');
                        location.reload();
                    },
                    error: function( response ) {
                        console.log( 'Failed to Submit Expense.' );
                        alert('Expense Not Submitted !! Please enter correct order id.');
                        location.reload();
                    }
                });
             });
        });         
</script>

<?php

add_action( 'wp_ajax_update_custom_field_order_expense_php', 'update_custom_field_order_expense_php' );
add_action('wp_ajax_nopriv_update_custom_field_order_expense_php', 'update_custom_field_order_expense_php');

function update_custom_field_order_expense_php() {
    $order_id = $_POST['orderid'];
    $order_expense = $_POST['expense'];
    $order_expense_reason = $_POST['expense_reason'];
    $order = wc_get_order( $order_id );
    if ( is_user_logged_in()) {
        $current_user = wp_get_current_user();
        $current_user_id = $current_user->ID;
    
        $driver_id = get_post_meta($order_id, 'lddfw_driverid', true);
        //$current_date = date_i18n( 'j F, Y', strtotime( $current_date_time ) );
        if($current_user_id == $driver_id  ){
            $order->update_meta_data( 'Driver Expense', $order_expense );
            $order->update_meta_data( 'Driver Expense Reason',$order_expense_reason);
            $order->save();
