We need to upgrade client’s file upload limit based on subscription each he paid/upgrade.

We have setup

• IPN URL = http://copyrightwebstamp.com/?s2member_paypal_notify=1
• IPN Notification is enabled
• We are testing in Sandbox mode
• IPN log file updated on each transaction

IPN log (letest 2 entries) from paypal-ipn.log:

API/Notifications Settings

Under Payment Notifications we have set following URL
http://copyrightwebstamp.com/upgrade-subscription.php?var=%%first_name%%

Script under upgrade-subscription.php file is:

<?php
mail('ceo@najeebmedia.com', 'Hello man','Hellow man '.$_REQUEST['var']);
?>

Problem

Our script is not running whenever payment is made. You are requested to help us out to fix this issue.

Hi Gaba.

The log says your custom attribute is wrong, it has to start with your domain name. [hilite path]Dashboard -› s2Member® -› PayPal® Buttons -› Shortcode Attributes (Explained)[/hilite]

The button generator will populate that attribute correctly for you. [hilite path]Dashboard -› s2Member® -› PayPal® Buttons -› Membership Level # Buttons[/hilite]

‘custom’ => ‘xyz123’,

2 => ‘Unable to verify `$_SERVER[“HTTP_HOST”]`. Please check the `custom` value in your Button Code. It MUST start with your domain name.’,

Fix that first and see if then notifications happen, please. If they still don’t, then try the suggestions in this article: Knowledge Base » Common Troubleshooting Tips.

If you’re using the post-registration auto-login hack, remove it for your tests, since it’s known to cause the notifications API to not work.

I hope that helps.

Thanks for reply, well IPN Log I pasted was wrong, as it was showing IPN txn being tested from Sandbox Tool, here is IPN log:

  's2member_log' => 
  array (
    0 => 'Unable to verify $_POST vars. This is most likely related to an invalid configuration of s2Member, or a problem with server compatibility.',
    1 => 'If you\'re absolutely SURE that your configuration is valid, you may want to run some tests on your server, just to be sure $_POST variables are populated, and that your server is able to connect/communicate with your Payment Gateway over an HTTPS connection.',
    2 => 's2Member uses the `WP_Http` class for remote connections; which will try to use `cURL` first, and then fall back on the `FOPEN` method when `cURL` is not available. On a Windows® server, you may have to disable your `cURL` extension; and instead, set `allow_url_fopen = yes` in your php.ini file. The `cURL` extension (usually) does NOT support SSL connections on a Windows® server.',
    3 => 'Please see this thread: `http://www.s2member.com/forums/topic/ideal-server-configuration-for-s2member/` for details regarding the ideal server configuration for s2Member.',
    4 => 'array (
  \'s2member_paypal_notify\' => \'1\',
)',
  ),
)

And I checked custom variable, it is started with domain name.

Could you try the server check tool? http://www.s2member.com/kb/common-troubleshooting-tips/#server

Also when I try to checkout to buy subscription (in sandbox mode) I got this error:

https://docs.google.com/a/najeebmedia.com/file/d/0B2u2KiDYT-rnYVp0dW80RXBWNmM/edit

any idea?

Well, it says there that it’s a temporary error they were having, apparently something on their side, not your fault.

Still, what I’d recommend is to not use the Sandbox at all, instead do live transactions, 1 cent is fine. Once you have those working without problems in your tests, if you can, do a final test for the actual amount you’ll charge your customers to make sure it works fine.
