Description

What we are needing is an experienced PHP programmer with osCommerce and CRE Loaded knowledge. We have a site that is up and running, but we are now receiving the following error message after we process our credit cards.

Warning: Cannot modify header information - headers already sent by (output started at /html/catalog/includes/modules/payment/innovative.php:460) in html/catalog/includes/functions/general.php on line 47

The credit cards are processed at the merchant just fine, but we are getting the error when redirecting to a page (We believe). We started getting this after we added the following code to the innovative.php file mentioned in the error.

exec($cmd, $return_string);

if ( empty($return_string) && $this->logfile) { // using exec no curl errors can be retrieved
error_log("Error from cURL using exec() since there is no $return_stringn", 3, $this->logfile);
}
if ($this->logfile) {
error_log("IGS RESPONSE using exec(): " . $return_string[0] . "n", 3, $this->logfile);
}
elseif ($this->use_exec == '1') { // if NOT (function_exists('exec') && $this->use_exec == '1'
if ($this->logfile) {
error_log("Sorry, exec() cannot be calledn", 3, $this->logfile);
}
} else{ // default behavior: cURL is assumed to be compiled in PHP

// echo "curl command<br>" . $cmd . "<br>";

$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, MODULE_PAYMENT_INNOVATIVE_URL);
curl_setopt ($ch, CURLOPT_HTTPPROXYTUNNEL, 1);
curl_setopt ($ch, CURLOPT_POST, 1);
curl_setopt ($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt ($ch, CURLOPT_PROXYTYPE, CURLPROXY_HTTP);
curl_setopt ($ch, CURLOPT_PROXY, "https://proxy.shr.secureserver.net:3128");
curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, 0);

if ($this->logfile) {
error_log("IGS REQUEST: " . $return_string . "n", 3, $this->logfile);
}
$return_string = curl_exec ($ch);
if (curl_errno($ch) && $this->logfile) {
$error_from_curl = sprintf('Error [%d]: %s', curl_errno($ch), curl_error($ch));
error_log("Error from cURL: " . $error_from_curl . "n", 3, $this->logfile);
}
if ($this->logfile) {
error_log("RESPONSE: " . $return_string . "n", 3, $this->logfile);
}
curl_close ($ch);
}

Line 47 from the general.php file is:

header('Location: ' . $url);

We need a developer to modify this code to ensure it will work. We do not believe it is due to a space issue of any file as this error usually appears.
