Codeigniter操作表单不起作用

Question

我试图理解为什么我的表单操作没有将我带到控制器...我按了模态上的更新按钮，这应该将模态上的信息更新到数据库中...当我按模态时，什么也没有发生，没有错误，没有消息，它只是关闭了模式，仅此而已。 帮助PLS！ 这是我的代码：

Answer 1

尝试这个

 <?php echo form_open(base_url() . 'admin/update_politic' , array('class' => 'form-horizontal form-groups-bordered validate', 'enctype' => 'multipart/form-data'));?>

Answer 2

您已使用base_url()?>admin/update_politic提交表单。 但是您没有提到该控制器。 如果您有管理员控制器，那就可以了。 否则，这就是提交该文件的原因。

Answer 3

代替按钮，使用< input type = "submit"值=“提交” class =“此处是您的类名”>
