数组无效的表单验证

Question

在我的表格上，我有一些复选框。他们是一个阵列。当我因某种原因提交表单时，它会清除修改复选框。然后回去看看没有检查。

我知道造成问题的原因是$this->form_validation->set_rules('permission[modify]', '', 'callback_modify_check_edit')

在set_rules上似乎不喜欢权限[修改] 或权限[修改] []

我如何解决这个问题？

  

控制器编辑功能：

public function edit() {

$this->load->library('form_validation');

$this->form_validation->set_rules('name', 'User Group Name', 'required');
$this->form_validation->set_rules('user_group_id', 'User Group Id', 'required');
$this->form_validation->set_rules('permission[modify]', '', 'callback_modify_check_edit');

if ($this->form_validation->run($this) == FALSE) {

$this->getForm();

} else {

$this->load->model('admin/user/model_user_group');

$this->model_user_group->editUserGroup($this->uri->segment(4), $this->input->post());

$this->db->select('permission');
$this->db->from($this->db->dbprefix . 'user_group');
$this->db->where('user_group_id', $this->session->userdata('user_group_id'));
$user_group_query = $this->db->get();

$permissions = unserialize($user_group_query->row('permission'));

$this->session->set_userdata($permissions);

$this->session->set_flashdata('success', 'Congratulations you have successfully modified' .' '. "<strong>" . ucwords(str_replace('_', ' ', $this->router->fetch_class())) .' '. $this->input->post('name') . "</strong>");

redirect('admin/users_group');

}

}

public function modify_check_edit() {
    if (!in_array('users_group', $this->session->userdata('modify'))) {

        $this->form_validation->set_message('modify_check_edit', 'You do not have permission to edit' );

    }
}

  

查看表单：

经过半个小时的努力试图找出答案后，回调的主要部分不在于 set_rules（） 权限[修改]

这里只修复了代码以便回拨，现在似乎正在运作。

public function modify_check_edit() {
    $this->load->library('form_validation');

    if (is_array($this->session->userdata('modify'))) {

        $permission = !in_array('users_group', $this->session->userdata('modify'));

        if ($permission) {

            $this->form_validation->set_message('modify_check_edit', 'You do not have permission to one' .' '. "<strong>" . ucwords(str_replace('_', ' ', $this->router->fetch_class())) .' '. $this->input->post('name') . "</strong>");

            return FALSE;

        } else {

            return TRUE;

        }

        return TRUE;

    } else {

        $this->form_validation->set_message('modify_check_edit', 'You do not have permission to one' .' '. "<strong>" . ucwords(str_replace('_', ' ', $this->router->fetch_class())) .' '. $this->input->post('name') . "</strong>");

        return FALSE;

    }
}
