Library: Campaign Monitor API

[eluser]Tobz[/eluser]
I ended up writing my own CM library. Here it is in case anyone wants to use it.

usage:

Code:

$this->load->library('campaignmonitor', array($api_key));
$respsonse = $this->campignmonitor->call('Client.GetDetail', array('ClientID'=>'xxxxxxxxxxx'));

The Class:

Code:

<?php
/**
* Campaign Monitor API Class

* usage:
* $cm = new Campaignmonitor($api_key);
* $response = $cm->call('Client.GetDetail', array('ClientID'=>'xxxxxx', ));
*/

class Campaignmonitor {

  private $api_url = 'http://api.createsend.com/api/api.asmx/';
  private $api_key = '';
  private $call_url = '';
  private $error = false;
  private $error_message = '';

  function Campaignmonitor($api_key = false) {
    // set API Key if present
    if (is_array($api_key)) {
      $this->api_key = $api_key[0];

    else {
      $this->api_key = $api_key;
    }
  }

  }

            return $this->error = $error;

    function get_error() {
