你好Guyzz我是Codeigniter的新手,我需要在系统中登录角色库方面获得帮助, 我在类别中有两个表第一个,第二个是user_reg,

在第二个存储有此类1,2,3的表category_id中,是否有可能获取此ID?

请给我建议和解决方案,我是CI的新手, 给我一些有关动态菜单和基于角色的登录访问的指导

数据库表示例:

CREATE TABLE IF NOT EXISTS `users` (
  `user_id` int(11) NOT NULL AUTO_INCREMENT,
  `first_name` varchar(100) NOT NULL,
  `last_name` varchar(100) NOT NULL,
  `username` varchar(100) NOT NULL,
  `password` text NOT NULL,
  `create_at` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
  PRIMARY KEY (`user_id`),
  KEY `user_id` (`user_id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=latin1;

INSERT INTO `users` (`user_id`, `first_name`, `last_name`, `username`, `password`, `create_at`) VALUES
(1, 'ali', 'qorbani', 'aliqorbani', '63bed66f3d9dcd13440490d90738f816', '2018-07-28 08:34:01'),
(2, 'mohammad', 'ahmadi', 'mohammad', '316946a88ad51d75465c4c0b1e4a066a', '2018-07-28 08:34:01');


CREATE TABLE IF NOT EXISTS `user_groups` (
  `group_id` int(11) NOT NULL AUTO_INCREMENT,
  `group_name` varchar(100) NOT NULL,
  `create_at` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
  PRIMARY KEY (`group_id`),
  KEY `group_id` (`group_id`)
) ENGINE=InnoDB AUTO_INCREMENT=5 DEFAULT CHARSET=latin1;

INSERT INTO `user_groups` (`group_id`, `group_name`, `create_at`) VALUES
(1, 'superadmin', '2018-07-28 08:35:56'),
(2, 'admin', '2018-07-28 08:35:56'),
(3, 'moderator', '2018-07-28 08:36:12'),
(4, 'customer', '2018-07-28 08:36:12');

CREATE TABLE IF NOT EXISTS `user_roles` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `user_id` int(11) NOT NULL,
  `group_id` int(11) NOT NULL,
  PRIMARY KEY (`id`),
  KEY `id` (`id`),
  KEY `user_id` (`user_id`),
  KEY `group_id` (`group_id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

ALTER TABLE `user_roles`
  ADD CONSTRAINT `user_roles_ibfk_1` FOREIGN KEY (`user_id`) REFERENCES `users` (`user_id`) ON DELETE CASCADE ON UPDATE CASCADE,
  ADD CONSTRAINT `user_roles_ibfk_2` FOREIGN KEY (`group_id`) REFERENCES `user_groups` (`group_id`) ON DELETE CASCADE ON UPDATE CASCADE;
COMMIT;
型号

代码将是这样。

// User_model

public function add($data){
    $this->db->insert('users',$data);
    return true;
}
public function update($data,$id){
    $this->db->where('user_id',$id);
    $this->db->update('users',$data);
    return true;
}

public function add_user_roles($user_id,$roles = array()){
    $this->db->where('user_id',$user_id);
    $this->db->delete('user_roles');
    foreach ($roles as $role){
        $this->db->insert('user_roles',['user_id'=>$user_id,'group_id'=>$role]);
    }
    return true;
}

控制器 编辑方法的示例将如下所示:

//Users controller
public function edit($user_id){
    if($this->form_validation->run() == FALSE) {
        $data_view['user'] = $this->User_model->get_user($user_id);
        $this->load->view('user_edit',$data_view);
    }else{
    $first_name = $this->input->post('first_name');
    $last_name = $this->input->post('last_name');
    $username = $this->input->post('username');
    $password = md5($this->input->post('password'));
    $user_roles = $this->input->post('roles');
    $data_user_update = array(
        'first_name'    =>  $first_name, 
        'last_name'     =>  $last_name, 
        'username'      =>  $username, 
        'password'      =>  $password
    );
    $this->User_model->add_user_roles$user_id,$user_roles);
    $this->User_model->update($data_user_update,$user_id);
    $this->session->set_flashdata('success','user updated correctly');
    redirect('users/edit/'.$user_id);
    }
}

再也不会使用这种方式! 创建2个不同的表(用户,用户组)。在用户表group_id中添加一列,然后使用join函数获取主题 有关更多信息,请参见this link

这是我的(post,post_tax,post_tax_relation)表屏幕截图。我认为它可以帮助您满足需要。 请记住,place个用户,+-------+-----------+ | Id | place | +-------+-----------+ | abcde | Santori | | abcde | Colombo | +-------+-----------+ 必须更新关系表(我的意思是删除所有引用该用户的关系,并在每次更新时创建新的关系)。 Posts table - (use it as your user table)

taxonomies - use it as your **User Groups**

relations - for collect all user permission levels
