The PHPAudit Instant Order Notification or ION Technology is our latest feature. If configured, PHPAudit ION will send a form post containing the client data, license data (if any), order data, invoice data and register data to a specified URL(s) for every new order. The ION handler then verifies the form post with the PHPAudit ION server, returning a simple "PASSED" or "FAILED" response. If the PHPAudit ION server returns "PASSED" you know the form post is legitimate. The possibilities of this new technology are endless, as you can imagine.


Once again, PHPAudit continues to lead the industry with new and innovative features. We are dedicated to total customer satisfaction and quality through technology. We prove this via innovations such as Instant Order Notification (ION).


Consider the diagram below as it illustrates how the ION Technology works.




Quick summary of the process:

- If configured, your order form sends out a detailed post to your ION handler

- This form post contains a unique verify sign

- The ION handler posts the verify sign back to PHPAudit

- PHPAudit returns a simple "PASSED" or "FAILED" response

- If "FAILED", the post was not legitimate

- If "PASSED", the post was legitimate - it is safe to "do something"



Example of an ION handler:


<?PHP
function validte_ion($verify_sign) 
    { 
    $request = "verify_sign={$verify_sign}"; 

    $header  = "POST /ion/validate_ion.php HTTP/1.0\r\n"; 
    $header .= "Content-Type: application/x-www-form-urlencoded\r\n"; 
    $header .= "Content-Length: " . strlen($request) . "rnrn"; 

    $fp=@fsockopen("example.com", 80, $errno, $errstr, 30); 

    if (!$fp) { return false; } 
    else 
        { 
        fputs($fp, $header, $request); 
        while(!feof($fp)) 
            { 
            $data = fgets($fp, 1024); 

            if (strcasecmp($data, 'PASSED') == 0) 
                { 
                return true; 
                } 
            else 
                { 
                return false; 
                } 
            } 

        fclose($fp); 
        } 

    return false; 
    } 

if ((!isset($_POST['verify_sign']))||($_POST['verify_sign']=='')) 
    { 
    // nothing to do 
    exit; 
    } 

if (!validate_ion($_POST['verify_sign'])) 
    { 
    // nothing to do 
    exit; 
    } 

// do something! it's a valid ION POST!!
