Retrieve the group id of user in Ion Auth - Codeigniter - php

Question

I am using Ion Auth for my codeigniter application and all seems good except for one thing.
I need to display a list of users along with the groups they are in. How can I retrieve the group id of a particular user without making my own models and querying for it.
$this->ion_auth->user($id)->row(); does not retrieve the group id.

Answer 1

Ion Auth has updated and removed the get_user function in the latest version. As a result of this, the below should return the current group id of the logged in user:
$this->ion_auth->get_users_groups()->row()->id
If you're wanting to get the group id of a particular user, you can pass the user id into the get_users_groups method.

Answer 2

get the Object:
$user_groups = $this->ion_auth->get_users_groups($user->id)->result();
Get the name of the group:
$this->ion_auth->get_users_groups($data['id'])->row()->name;
In my case:
$data['groups'] = $this->ion_auth->get_users_groups($data['id'])->row()
You can check the offcial doc about get users groups:

Answer 3

I came across this because I wanted to add a user's group_id(s) to the session upon successful login. In case anyone is interested, here's how I did it (once i managed to figure out where everything was being done).
In ion_auth_model.php, I took the set_session function:
public function set_session($user)
{
$this->trigger_events('pre_set_session');
$session_data = array(
'identity' => $user->{$this->identity_column},
'username' => $user->username,
'email' => $user->email,
'user_id' => $user->id, //everyone likes to overwrite id so we'll use user_id
'old_last_login' => $user->last_login
);
$this->session->set_userdata($session_data);
$this->trigger_events('post_set_session');
return TRUE;
}
and modified it to this:
public function set_session($user)
{
$this->trigger_events('pre_set_session');
$session_data = array(
'identity' => $user->{$this->identity_column},
'username' => $user->username,
'email' => $user->email,
'user_id' => $user->id, //everyone likes to overwrite id so we'll use user_id
'old_last_login' => $user->last_login
);
//get user group ids for user and pass to session
$groups = $this->ion_auth->get_users_groups($user->id)->result();
foreach ($groups as $row){
$session_data['groups'][] = $row->id;
}
$this->session->set_userdata($session_data);
$this->trigger_events('post_set_session');
return TRUE;
}
now it writes an array to the session called groups that is a list of all the groups the user belongs to.
The only other thing I had to do was to modify the logout function in Ion_auth.php (in application/libraries) to make sure the group session variable is unset by adding
$this->session->unset_userdata('groups');
to the list of other unset_userdata() statements.
I know I probably should have just extended the libraries/models to keep the core untouched, but you could take what I did and easily do that.
hope this helps someone.

Try adding this to ion_auth_model.php
(Or place the query somewhere else)
/**
* get_all_users_with_group
*
* #return array
**/
public function get_all_users_with_group()
{
$this->trigger_events('get_all_users_with_groups');
return $this->db->select(
$this->tables['users'].'.*, '.
$this->tables['users_groups'].'.'.$this->join['groups'].' as group_id, '.
$this->tables['groups'].'.name as group_name, '.
$this->tables['groups'].'.description as group_desc'
)
->join($this->tables['users_groups'], $this->tables['users_groups'].'.'.$this->join['users'].'='.$this->tables['users'].'.id')
->join($this->tables['groups'], $this->tables['users_groups'].'.'.$this->join['groups'].'='.$this->tables['groups'].'.id')
->get($this->tables['users']);
}

use in the controller:
$groups = array(1,2,3,4);
$this->data['list_staff'] = $this->ion_auth->users($groups)->result(); // выбираем всех teachers из зарегистрированных пользователей
foreach ($this->data['list_staff'] as $k => $one_staff)
{
$this->data['list_staff'][$k]->groups = $this->ion_auth->get_users_groups($one_staff->id)->result();
}
and in view use:
<?php foreach($list_staff as $one):?>
<?php foreach ($one->groups as $group):?>
<?php echo $group->description;?>,
<?php endforeach?>
<?endforeach;?>
but what about query to get groups for current logged in user (for example in my profile) I find next decision.
Controller:
$this->data['this_user_groups'] = $this->ion_auth->get_users_groups()->result();
and view just:
<?php foreach ($this_user_groups as $group):?>
<?php echo $group->description;?>,
<?php endforeach?>
