在会话数组HMVC Codeigniter中的数组内签入值

Question

i am making this one where i want to pass the user data on my sessions as you can see on my codes

controller

public function loginValidate(){

    $this->load->library('form_validation');


    $this->form_validation->set_rules('USERNAME','Username','required|trim|callback_validateCreds');
    $this->form_validation->set_rules('PASSWORD','Password','required|trim');

    if($this->form_validation->run($this) == FALSE){

        $this->index();

    }else{
        $data = array(
            'USERNAME' => $this->input->post('USERNAME'),
            'is_logged_in' => true,
--------->>'user_data' => $this->Login_Model->userinfo()
        );

        $this->session->set_userdata($data);
        $this->dashboard();
    }
}

models

public function userinfo(){

    $sql = "SELECT
                tbl_users.ID_NUM,
                tbl_users.USERNAME,
                user_group.GROUP_NAME,
                user_rights.RIGHTS,
                usertypes.USERTYPE,
                department.DEPARTMENT
            FROM tbl_users
                INNER JOIN user_group
                ON tbl_users.GROUP_ID = user_group.GROUP_ID
                INNER JOIN user_rights
                ON user_group.GROUP_ID = user_rights.GROUP_ID
                INNER JOIN usertypes
                ON user_rights.RIGHTS = usertypes.USERCODE
                INNER JOIN department
                ON usertypes.DEP_ID = department.DEP_ID
            WHERE tbl_users.USERNAME = ?
            AND tbl_users.PASSWORD = ? ";

    $data = array(
                    'USERNAME' => $this->input->post('USERNAME'),
                    'PASSWORD' => $this->input->post('PASSWORD')
                );

    $query = $this->db->query($sql, $data);
    return $query;
}   

what i wanted to do is when i log-in to check the values inside my user_data array. for example

if (userdata array in my sessions array have the value admin){

show this}

i cannot or atleast i dont think that i can break down that array because my query output will be for example.

---------------------------------------------
username   |  group_name     |  rights     |
---------------------------------------------
abc        |  group_1        |  admin1     |
---------------------------------------------
abc        |  group_1        |  admin2     |
---------------------------------------------
abc        |  group_1        |  admin3     |
---------------------------------------------

how will i be able to check that array inside the sessions array if some specific value is inside that array. for example if the array has admin1 i'll do this and etc..

Answer 1

use this code

$sessionarray = $this->session->userdata();

$sessionarray['USERNAME'] ;

or your condition

if($sessionarray['USERNAME']=='admin')
