ARB PHP sample code gives me a blank page

[parabellum]

Hello,

using the simple code from the README file of the PHP SDK I've setup 2 pages.

one using ARB the other using AIM, both located in the same folder using the same sdk files.

the AIM works fine and creates a charge on my test account, the ARB gives me a blank page and doesn't create any subscription in my test account.

What I m missing?

<?php

require_once 'anet_php_sdk/AuthorizeNet.php'; 

    define("AUTHORIZENET_API_LOGIN_ID", "my ID");

    define("AUTHORIZENET_TRANSACTION_KEY", "my key");

    $subscription                          = new AuthorizeNet_Subscription;

    $subscription->name                    = "PHP Monthly Magazine";

    $subscription->intervalLength          = "1";

    $subscription->intervalUnit            = "months";

    $subscription->startDate               = "2011-03-12";

    $subscription->totalOccurrences        = "12";

    $subscription->amount                  = "12.99";

    $subscription->creditCardCardNumber    = "6011000000000012";

    $subscription->creditCardExpirationDate= "2018-10";

    $subscription->creditCardCardCode      = "123";

    $subscription->billToFirstName         = "Rasmus";

    $subscription->billToLastName          = "Doe";

    // Create the subscription.

    $request = new AuthorizeNetARB;

    $response = $request->createSubscription($subscription);

    $subscription_id = $response->getSubscriptionId();

    echo($subscription_id);

?>

<?php

    require_once 'anet_php_sdk/AuthorizeNet.php'; 

    define("AUTHORIZENET_API_LOGIN_ID", "my ID");

    define("AUTHORIZENET_TRANSACTION_KEY", "My key");

    define("AUTHORIZENET_SANDBOX", true);

    $sale = new AuthorizeNetAIM;

    $sale->amount = "5.99";

    $sale->card_num = '6011000000000012';

    $sale->exp_date = '04/15';

    $response = $sale->authorizeAndCapture();

    if ($response->approved) {

        $transaction_id = $response->transaction_id;

        echo($transaction_id);

    }

    ?>

I tried adding the line  

define("AUTHORIZENET_SANDBOX", true);

to the ARB code but same result 

thank you for any help

Well, you might try printing something else at the end to find out if it's getting all the way through and just not passing back a subscription ID. If that fails, then you need to check your error logs to find out what's going on.

Thanks you for the feedback ;-)

What else could I print  ?

I'm learning as I go and was trying to find out how to get a response code but didn't find out how to get that value back yet.

Would that be a good direction for me to pursue?

Thanks

If you're getting a blank page that usually means you have a syntax error and error reporting has been turned off so you can't see the actual error. Place the following code on the line after your opening PHP tag:

error_reporting(E_ALL);

That should allow your code to display any errors your have so you can better troubleshoot it.

If that doesn't work follow TJPride's advice and use echo statements throughout the code to see where it fails. This should give you a point in the right direction:

<?php
    require_once 'anet_php_sdk/AuthorizeNet.php'; 

    define("AUTHORIZENET_API_LOGIN_ID", "my ID");
    define("AUTHORIZENET_TRANSACTION_KEY", "my key");

    echo "Made it to 1\n"; 

    $subscription                          = new AuthorizeNet_Subscription;
    $subscription->name                    = "PHP Monthly Magazine";
    $subscription->intervalLength          = "1";
    $subscription->intervalUnit            = "months";
    $subscription->startDate               = "2011-03-12";
    $subscription->totalOccurrences        = "12";
    $subscription->amount                  = "12.99";
    $subscription->creditCardCardNumber    = "6011000000000012";
    $subscription->creditCardExpirationDate= "2018-10";
    $subscription->creditCardCardCode      = "123";
    $subscription->billToFirstName         = "Rasmus";
    $subscription->billToLastName          = "Doe";

    echo "Made it to 2\n"; 

    // Create the subscription.
    $request = new AuthorizeNetARB;

    echo "Made it to 3\n"; 

    $response = $request->createSubscription($subscription);

    echo "Made it to 4\n"; 

    $subscription_id = $response->getSubscriptionId();

    echo "Made it to 5\n"; 
    
    echo($subscription_id);

    echo "Made it to 6\n"; 
?>

Was really stupid, as often is ;-)

I found out how to print the $response and found out I was using a start date that was in the past, whooops !

All good now

Thanks for the help
