为什么我的表单数据没有在 CodeIgniter 中从一个页面处理到另一个页面？

Question

我正在为我的 Web 应用程序开发管理面板。会员管理部分的索引是最新会员帐户的列表。每个成员都有一个复选框，管理员可以选中该复选框以一次删除多个用户。我使用 jQuery 提交带有链接的表单。由于表单在成员管理部分（成员/主页）的索引上，我希望表单的过程在成员/删除上。当访问成员/删除控制器时，可以选择在 URL 段中提供单个成员 ID，或者管理员可以使用成员索引页面上的表单。

我的问题是复选框中的所有数据都没有传递给成员/删除控制器。我试过 $this->input->post('delete_members') 和 $_POST['delete_members']。我还尝试将表单的方法更改为 GET，然后更改为 $_GET['delete_members']。我得到“未定义的索引：delete_members 我尝试的一切。有什么想法吗？

PS：我有一条将 members/delete 更改为 members/home/delete 的路由

成员控制器：（成员/家庭）

Answer 1

试试这个：

替换这一行：

form_open('members/delete', 'id="delete" role="form"')

与：

form_open('home/delete', 'id="delete" role="form"')

Answer 2

改变方法

function delete($member_id = '') { 
  // your code here
}

到

function delete() { 
 echo '<pre>'; print_r($_POST); die;
 // your code here
}

检查您的表单帖子是否有效。它在删除方法中发布数据，您可以根据逻辑执行其余代码。

Answer 3

我意识到，由于我购买的主题附带了 jQuery iCheck 插件，因此没有发布任何复选框值。当我对主题持怀疑态度时，我禁用了 JS，你不知道吗，复选框值开始发布。
