How to get users list in codeigniter? - php

Question

I am trying to get list of users from Users table in codeigniter. My problem is that if am using following code than try to print out the result, it's giving me blank array while printing query using last_query() function and running this query in phpmyadmin is giving correct result.
My code in model
$data = $this->db->select('u.*')
->from('users u')
->join('users_groups ug','ug.user_id = u.id')
->join('groups g','g.id = ug.group_id')
->where('g.id',7)
->get()
->result();
this code is giving me blank array then what i did is print the query using following code
echo $this->db->last_query();
and this is what query was
SELECT `u`.* FROM `users` `u` JOIN `users_groups` `ug` ON `ug`.`user_id` = `u`.`id` JOIN `groups` `g` ON `g`.`id` = `ug`.`group_id` WHERE `g`.`id` = 7
which is working fine. but i am trying to print the data using print_r($data)
is giving me blank array.
Can anyone tell me what can be the issue ?

You may try this simple way to join table. you may try this and can
change fields name table name and method according to your
require.
public function getUser() {
$this->db->select('users');
$this->db->from('Users');
$this->db->where('users_groups.user_id',1);
$this->db->join('users_groups', 'users.id = users_groups.user_id');
$query = $this->db->get();
$result = $query->result_array();
var_dump($result); // display data in array();
return $result;
}

Actually, at the end of 2 hrs of the journey, I found that I forgot to configure new database.
All the answers were correct in this case.
