Hi Guys,
I usually try to dig in and fix my own problems but this one has me scratching my head (perhaps I'm just doing this WRONG.)
So, I have used Phil Sturgeon's popular REST client/server library. I needed to modify the class slightly for a specific API. Since I wanted to keep his code intact for future updates, I extended his Rest and Curl classes to suit my needs (I did have to change visibility scope from private to protected but that's it.)
I'm having an issue with loading my extended library (the details are not really important, skip down):
Code:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
/**
* @author REST Philip Sturgeon
* @author CB_REST Brett Millett
*/
require_once 'Rest.php';
class CB_REST extends REST {
private $developer_key;
private $clerk_key;
function __construct($config = array())
{
$this->CI =& get_instance();
log_message('debug', 'CB REST Class Initialized');
// in order to get HEAD functionality, call clickbank extended curl instead.
$this->CI->load->library('cb_curl', NULL, 'curl');
// If a URL was passed to the library
if(!empty($config))
{
$this->initialize($config);
}
}
function initialize($config) {
$this->rest_server = @$config['server'];
if(substr($this->rest_server, -1, 1) != '/')
{
$this->rest_server .= '/';
}
$this->http_auth = isset($config['http_auth']) ? $config['http_auth'] : '';
$this->http_user = isset($config['http_user']) ? $config['http_user'] : '';
$this->http_pass = isset($config['http_pass']) ? $config['http_pass'] : '';
$this->developer_key = isset($config['developer_key']) ? $config['developer_key'] : '';
$this->clerk_key = isset($config['clerk_key']) ? $config['clerk_key'] : '';
}
// clickbank does not accept data in message body so we will send the post verb but add params to URI (just like GET.)
public function post($uri, $params = array(), $format = NULL)
{
if(!empty($params))
{
$uri .= '?'.http_build_query($params);
}
return $this->_call('post', $uri, NULL, $format);
}
protected function _set_headers() {
$this->CI->curl->http_header("Authorization: {$this->developer_key}:{$this->clerk_key}");
$this->CI->curl->http_header('Accept: '.$this->mime_type);
}
protected function _call($method = 'get', $uri, $params = array(), $format = NULL) {
if($format !== NULL) {
$this->format($format);
}
$this->_set_headers();
// Initialize cURL session
$this->CI->curl->create($this->rest_server.$uri);
// If authentication is enabled use it
if($this->http_auth != '' && $this->http_user != '') {
$this->CI->curl->http_login($this->http_user, $this->http_pass, $this->http_auth);
}
// We still want the response even if there is an error code over 400
$this->CI->curl->option('failonerror', FALSE);
// turn off verify peer since this fails for clickbank certificate (SSL is good enough)
$this->CI->curl->option('ssl_verifypeer', FALSE);
// Call the correct method with parameters
$this->CI->curl->{$method}($params);
// Execute and return the response from the REST server
$response = $this->CI->curl->execute();
if ( $response !== FALSE ) {
// Format and return
return $this->_format_response($response);
}
// return false on protocol error or connection timeout
return FALSE;
}
public function listorder($reciept)
{
return $this->get('rest/1.2/orders/' . $reciept, array(), 'json');
}
public function is_order_active($receipt)
{
// timeout quicker for this call.
$this->CI->curl->option('timeout', 5);
if ( ! $this->is_valid_receipt($receipt) )
return FALSE;
$response = $this->head('rest/1.2/orders/' . $receipt);
if ( $response === FALSE ) //network error, just return true.
return TRUE;
// reset timeout.
$this->CI->curl->option('timeout', 30);
switch( (int) $this->CI->curl->info['http_code'] ) {
case 204:
return TRUE;
break;
default:
return FALSE;
}
}
// head function
public function head($uri, $params = array(), $format = NULL)
{
return $this->_call('head', $uri, $params, $format);
}
private function is_valid_receipt($receipt)
{
//... truncated
}
}

I an getting the infamous error:
Quote:An Error Was Encountered
Unable to load the requested class: cb_rest
Strange thing is that I get no error on my development machine (OSX via MAMP.) This lib is being loaded for a login routine and the really strange thing is that for most users, I do not get this error. When I try the same user login on my development machine, it loads fine. I know that you (and I myself) suspect that this has something to do with code before this, but there are no variables that are affected from my debugging (I'm using subversion to push changes to production so I know they are exactly the same.) I've checked permissions. Not sure what is going on. I can run a debugger on development but not on production. I don't want to stick debugging code in core files either if possible (I suppose I could make a MY_Loader class and copy code and put in debugging code.) Anyways, if anyone sees some bad practices, please call me out!
Thanks!
