Non-Object Error

[ShoeLace1291]

I am trying to modify a class that I found that is a Steam API class.  I want it to work with codeigniter.  I keep getting call to a member function on a non-object error when I call the getProfileData function.  Not sure why it's happening.  Here is the code:

 

The library:

<?php

// Disable XML warnings to avoid problems when SteamCommunity is down

libxml_use_internal_errors(true);

// Use SteamUtility to fetch URLs and other stuff

require_once 'SteamUtility.php';

*/

class SteamUser {

 

private $userID;

private $vanityURL;

private $apiKey;

public $info;

 

/**

function __construct($params){

 

$userId = $params['userId'];

 

$this->CI =& get_instance();

 

$this->CI->load->config('steam');

 

if(empty($userId)) {

echo "Error: No Steam ID or URL given!", PHP_EOL;

return NULL;

}

if(is_numeric($userId)) {

$this->userID = $userId;

}

else {

$this->vanityURL = strtolower($userId);

$this->apiKey = $this->CI->config->item('api_key');

$i++;

}

 

}

}

 

return $info;

 

}

 

The model where I call the library:

function retrieve($member_id = 0, $page = 1, $limit = 10){

 

$info = array();

 

$this->db->select('memberId AS id, facebookId, steamId, userName, emailAddress, dateJoined, dateBorn')

->from('members')

->where('memberId', $member_id)

->limit(1);

 

if($query = $this->db->get()){

 

if($query->num_rows() > 0){

 

$member = $query->row_array();

var_dump($member);

$info = $member;

 

if($member['steamId'] != ''){

 

$this->load->library('SteamUser', array('userId' => $member['steamId']));

$steam = $this->SteamUser->getProfileData();

 

$info['steam'] = array(

'id' => $member['steamId'],

'avatar' => $steam['avatarIcon']

);

 

}

 

 

}

 

}

 

$this->info = $info;

 

}

It doesn't appear the class is being loaded and an object generated.

Is the SteamUser class file named according to the frameworks' guidelines. 

Is it located in the main libraries folder or the application/libraries folder.

If it is located in a sub-directory folder you'll need to add that path to the class loader.

$this->load->library('subdirectory/SteamUser', array('userId' => $member['steamId']));
