表格成功后取消设置会话不起作用

Question

当我取消选中我的修改和访问权限中的复选框时，如果表单提交成功，它不会从会话中取消设置它.

我想要实现的是在我的编辑功能上，如果未选中任何复选框，那么当表单提交成功时，它将 从会话中取消 。因为需要从会话中取消设置的原因是因为当用户登录时权限修改和访问被设置到会话中。

在我的编辑中尝试过但当复选框为空时没有取消设置后，我如何才能使它像我一样工作

如果我使用这个 $this->session->unset_userdata('modify'); 它取消设置会话中的所有修改数组，我只需要它取消设置与未选中的复选框匹配的数组。

public function edit() {

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

if ($this->input->server('REQUEST_METHOD') == 'POST') {

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

if ($this->session->userdata('user_id') == TRUE) {

if (isset($_POST['permission[access]'])) {

$this->session->unset_userdata('permission[access]');

}

if (isset($_POST['permission[modify]'])) {

$this->session->unset_userdata('permission[modify]');

}

}

redirect('admin/users_group');

}

$this->getForm();

}

public function getForm() {
$data['title'] = "Users Group";

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

$user_group_info = $this->model_user_group->getUserGroup($this->uri->segment(4));

if ($this->uri->segment(4) == FALSE) {
    $data['name'] = $this->input->post('name');
} else {
    $data['name'] = $user_group_info['name'];
}

if ($this->uri->segment(4) == FALSE) {
    $data['user_group_id'] = $this->input->post('user_group_id');
} else {
    $data['user_group_id'] = $user_group_info['user_group_id'];
}

$ignore = array(
'admin',
'dashboard',
'filemanager',
'login',
'menu',
'register',
'online',
'customer_total',
'user_total',
'chart',
'activity',
'logout',
'footer',
'header',
'permission'
);

$data['permissions'] = array();

$files = glob(FCPATH . 'application/modules/admin/controllers/*/*.php');

foreach ($files as $file) {

    $permission =  basename(strtolower($file), '.php');

    if (!in_array($permission, $ignore)) {
        $data['permissions'][] = $permission;
    }

}

$permission_access = $this->input->post('permission');

if (isset($permission_access)) {
    if (isset($permission_access['access'])) {
        $data['access'] = $permission_access['access'];
    } elseif (!empty($user_group_info['permission']['access'])) {
        $data['access'] = $user_group_info['permission']['access'];
    } else {
        $data['access'] = array();
    }
}

$permission_modify = $this->input->post('permission');

if (isset($permission_modify)) {
    if (isset($permission_modify['modify'])) {
        $data['modify'] = $permission_modify['modify'];
    } elseif (!empty($user_group_info['permission']['modify'])) {
        $data['modify'] = $user_group_info['permission']['modify'];
    } else {
        $data['modify'] = array();
    }
}

$this->load->view('template/user/users_group_form.tpl', $data);

}

我找到了让它工作的方法我从数据库中获得了会话然后重新设置表单中的会话，而不使用 unset_sessions();

public function edit() {

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

    if ($this->input->server('REQUEST_METHOD') == 'POST') {

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

        $user_group_query = $this->db->query("SELECT permission FROM " . $this->CI->db->dbprefix . "user_group 
            WHERE user_group_id = '" . (int)$this->session->userdata('user_group_id') . "'");

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

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

        redirect('admin/users_group');

    }

    $this->getForm();
}
