如何使某些内容仅对管理员/ mod用户可见

Question

I would like to know what the best practice is to restrict access for the user to some parts of the content within my view. I am using CodeIgniter. When the user logs in I set the user data inside the session like this:

controller

$this->session->set_userdata('user_id', $user_id);
//..
$this->load->view('view');

Now inside the view there are two DIV s. One should be visible to everybody and the other has to only be visible for admin or mods. Below is the code.

view

<div id="log_out">
//visible to everybody
</div>

//Is it possible to put this div as a part of if function? Something like this:
  //if <php $this->session->userdata('user_id') ?>

<div id="user_management">
//only visible to admin
</div>

//And how would I enclose the part that is restricted?

Or should this be done completely different? Should I store somewhere as what the user is currently logged in. If it is regular user, admin or mod? Thank you all in advance for reading and your replies.

Answer 1

I think that better solution is to divide that view to 2 separate views. Then check in controller if user is an admin (read that from session), and load both views if yes, and just one view if is not.

Answer 2

Just put a if condition something like this . 1 stands for admin in this case

   <?php if($this->session->userdata('usergroup') == '1') : ?>
   ---------do something---------
   <?php endif;?>
