Codeigniter问题

Question

我似乎无法在控制器中找到问题。这是我的代码。我确实使用print_r（$ customer）检查了它，所有的信息都保存在我的表中，除了必须保存在文件中的文件名＆＃39;柱。我无法找到错误。

首先，类名必须是这样的......

class Billing extends CI_Controller {

您可以将控制器保存为“billing.php”，但班级名称的第一个字母必须是大写字母。

e.g：

login_ctrl.php -->>> class Login_ctrl extends CI_Controller {
user_names.php -->>> class User_Names extends CI_Controller {

试试吧。也许现在它可以运行.. :)
