Php 如何在WooCommerce中为访客购买者分配自定义客户代码

我正在做一个Electron 商务项目.当客户购买产品时，会根据他们的名字、姓氏和序列号为他们分配一个客户代码.它被会计软件使用.

以下是我的代码:

add_action( 'show_user_profile', 'ipx_user_profile_fields' );
add_action( 'edit_user_profile', 'ipx_user_profile_fields' );

function ipx_user_profile_fields( $user ) { ?>
    <h3><?php _e("IPX", "blank"); ?></h3>

    <table class="form-table">
    <tr>
        <th><label for="ipx_customer_code"><?php _e("Customer Code"); ?></label></th>
        <td>
            <input type="text" name="ipx_customer_code" id="ipx_customer_code" value="<?php echo esc_attr( get_the_author_meta( 'ipx_customer_code', $user->ID ) ); ?>" class="regular-text" /><br />
            <span class="description"><?php _e("This field should contain only the IPX Customer Code."); ?></span>
        </td>
    </tr>
    </table>
<?php }

add_action( 'personal_options_update', 'save_ipx_user_profile_fields' );
add_action( 'edit_user_profile_update', 'save_ipx_user_profile_fields' );

function save_ipx_user_profile_fields( $user_id ) {
    if ( !current_user_can( 'edit_user', $user_id ) ) { 
        return false; 
    }
    update_user_meta( $user_id, 'ipx_customer_code', $_POST['ipx_customer_code'] );
}

/**
 * Generate customer code based on user's first name, last name and a sequential number
 */
function generate_customer_code($user_id) {
    $user = get_userdata($user_id);
    $first_name = $user->first_name;
    $last_name = $user->last_name;

    // Get the current sequential number for the customer code
    $sequential_number = get_user_meta($user_id, 'sequential_customer_code', true);
    if (!$sequential_number) {
        $sequential_number = 0;
    }

    // Loop until a unique customer code is generated
    do {
        $sequential_number++;
        // Generate the customer code
        $customer_code = strtoupper(substr($first_name, 0, 4) . substr($last_name, 0, 4) . sprintf('%02d', $sequential_number));
        // Check if the customer code already exists
        $user_query = new WP_User_Query(array(
            'meta_key' => 'ipx_customer_code',
            'meta_value' => $customer_code
        ));
    } while (!empty($user_query->results));

    // Save the customer code and sequential number as separate custom fields
    update_user_meta($user_id, 'ipx_customer_code', $customer_code);
    update_user_meta($user_id, 'sequential_customer_code', $sequential_number);
}
add_action('user_register', 'generate_customer_code');

它判断客户代码是否已被使用，如果已使用，则(按顺序)移动到下一个代码.

我一直在测试这一点，遇到了一个问题.只有当客户创建帐户时，它才起作用.我的客户坚持认为访客访问应该保持打开状态，这意味着永远不会生成客户代码.

有没有办法将此信息存储在wp_wc_Customer_Lookup表中？它记录了所有的客户，无论他们是否已经注册.我认为我的客户仍然希望在某个地方看到客户代码(在WooCommerce的Customers选项卡上？)，但它需要针对每个客户，而不仅仅是注册客户.

任何 idea 都将不胜感激.对于任何不可靠的编码，我提前道歉-我的PHP很粗糙，但我宁愿try 也不愿不try .
