Tank Auth v1.0 (CI authentication library)

[eluser]Unknown[/eluser]
Hello,

I added a basic user level support in this way:

Added a field in the 'users'-table in MySQL
-------------------------------------------
field:user_level
type:tinyint(16)
attr:UNSIGNED
Null:No
Default:0

in the Tank_auth.php - library I changed this:

around line 71:

Code:

$this->ci->session->set_userdata(array(
    'user_id'    => $user->id,
    'username'    => $user->username,
    'status'    => ($user->activated == 1) ? STATUS_ACTIVATED : STATUS_NOT_ACTIVATED,
));

into this :

Code:

$this->ci->session->set_userdata(array(
    'user_id'    => $user->id,
    'username'    => $user->username,
    'userlevel'    => $user->user_level,
    'status'    => ($user->activated == 1) ? STATUS_ACTIVATED : STATUS_NOT_ACTIVATED,
));

And around line 587:

Code:

$this->ci->session->set_userdata(array(
    'user_id'    => $user->id,
    'username'    => $user->username,
    'status'    => STATUS_ACTIVATED,
));

into this:

Code:

$this->ci->session->set_userdata(array(
    'user_id'    => $user->id,
    'username'    => $user->username,
    'userlevel'    => $user->user_level,
    'status'    => STATUS_ACTIVATED,
));

and somewhere around line 155 (after get_username()-function) I added these 2 functions:

Code:

/**
* Get userlevel
*
* @return    string
*/
function get_userlevel()
{
    return $this->ci->session->userdata('userlevel');
}
    
/**
* Validate userlevel
*
* @return    bool
*/
function validate_userlevel($level = 0)
{
    if($this->ci->session->userdata('userlevel') >= $level)
    {
        return TRUE;
    }
    return FALSE;
}

Usage in your controllers:

To get the users level:

Code:

$data['user_id']    = $this->tank_auth->get_user_id();
            $data['username']    = $this->tank_auth->get_username();
            $data['userlevel']    = $this->tank_auth->get_userlevel();
            $this->load->view('welcome', $data);

To validate the userlevel:

Code:

if($this->tank_auth->validate_userlevel(1))
            {
            // show or do something...
            }

The validation is simple:

a standard user gets level 0, every higher level is allowed to see the lower levels.
So if you create an admin user and give it level 9, you have 10 levels. But you can make it as high as you want.
In the example code level 0 is blocked and level 1 and up are granted access.
