So this code works with dollars and the mtgox api:
public function runUpdate() {
// print "update running\n";
$path = "1/BTCUSD/ticker";
$req = array();
// API settings
$key = '';
$secret = '';
// generate a nonce as microtime, with as-string handling to avoid problems with 32bits systems
$mt = explode(' ', microtime());
$req['nonce'] = $mt[1].substr($mt[0], 2, 6);
// generate the POST data string
$post_data = http_build_query($req, '', '&');
// generate the extra headers
$headers = array(
'Rest-Key: '.$key,
'Rest-Sign: '.base64_encode(hash_hmac('sha512', $post_data, base64_decode($secret), true)),
);
// our curl handle (initialize if required)
static $ch = null;
if (is_null($ch)) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; MtGox PHP client; '.php_uname('s').'; PHP/'.phpversion().')');
}
curl_setopt($ch, CURLOPT_URL, 'http://data.mtgox.com/api/'.$path);
// run the query
$res = curl_exec($ch);
if ($res === false) throw new Exception('Could not get reply: '.curl_error($ch));
$dec = json_decode($res, true);
if (!$dec) throw new Exception('Invalid data received, please make sure connection is working and requested API exists');
$btcdata = $dec;
$currency = "BTC";
$value = $btcdata['return']['avg']['value'];
if ((float)$value) {
$value = 1/$value;
$this->db->query("UPDATE " . DB_PREFIX . "currency SET value = '" . (float)$value . "', date_modified = '" . $this->db->escape(date('Y-m-d H:i:s')) . "' WHERE code = '" . $this->db->escape($currency) . "'");
}
$this->db->query("UPDATE " . DB_PREFIX . "currency SET value = '1.00000', date_modified = '" . $this->db->escape(date('Y-m-d H:i:s')) . "' WHERE code = '" . $this->db->escape($this->config->get('config_currency')) . "'");
$this->cache->delete('currency');
}
}
?>
I want to change it so it works with euro's and the
bitcoincharts api. could somebody please tell me how?
