Thank you a lot

Hi, could you elaborate on the problem that you are experiencing? Can you tell us what you were trying to achieve and how did it go wrong? Perhaps provide us with the code that you are using.

 

This would be useful to us and anyone that wish to help you.

 There is an example list of buyers, where the IPN always sent empty post data, i have daily over 50 successfuly IPN proccesses, so the problem can't be in my script.

So please can you look at this emails to confirm, there aren't any problems?

 Thank you

Hello,

The reason you receive empty data is that some of your customer have special characters in their name or address (ex: Š, á, etc...) and the IPN gets cut off.

We recently found out about this issue and are currently working on fixing it. We will be sending url encoded IPNs to avoid this and it is scheduled to be released sometime next week.

We will keep you posted about it.

 HI

We as well experience this issue (www.buxout.com)

I hope this gets fixed very soon :)

Hello, My clients have also been experiencing this problem, though it didn't seem to happen before the 16th of November If the problem is special characters in names/addresses) -- and it certainly sounds plausible to me given the fact that your software also doesn't like characters such as apostrophes and ampersands in item descriptions -- I do hope it can be resolved quickly. Having to look up every relevant transaction that has been effected is very cumbersome. Please keep us informed about the progress towards a solution to this problem. Thank you.

 Hi,

Have you guys made any changes today?  I've been receiving *alot* more empty IPN postings.  As a matter of fact, all the transactions after 3:35pm EST have been empty. They can't all have special characters in them as many of these are returning customers that did not cause problems before.

What's going on?

Yup same here ever since this afternoon when they went down for maintenance Alertpays IPN has sent nothing. Not impressed. We now have to pull an all nighter manually crediting orders and hope Alertpay fixes this in the morning.

It looks like they did not test their recent update, cause IPN has not worked since then.

 Hello,

 We have recently changed the IPN to post URL encrypted data, this may have caused some of the scripts that do not URL decode the data to think the data is "empty".

 

we have now reverted back to the old code. Please start decodeing the URL post as we will start enforcing the URL encoding after the new year.

 

If you have lost any post data between November 27th 6:00pm and November 28th 10:30am. please let us know and we will resend the data again.

 

Thank you for your understanding.

 Hi,

 

Thanks for getting IPN working again.  That will make my workday *alot* easier.

I'm not sure I understand what you mean by "URL encrypted data"  This sites I administer send me error messages when my IPN URL receives no POST data.  These messages include GET and SERVER data as well and I didn't see any data sent by AlertPay to these either.

Could you provide an example of how to decode the URL post using PHP?  Apparently the script I've been using for that past 5 months isn't able to do it.

Thank you.

If your going to render all IPN scripts effectively obsolete maybe a little notification and information ahead of time would be helpful?

 Before we URL Encode the IPN, we will give you a notification and update the sample scripts to show you how you can decode the IPN.

 

In order to decode a string in PHP use the following:

 

urldecode ( string $str )

 

Thank you,

Thanks.  I did know about PHP's urldecode() function, but am still confused as to how we were supposed to use it for POST values.

Are you saying that you're going to start passing all data through a query string appended to the IPN URL?  That would make input available through GET, not POST.  I'm not sure why GET would be preferrable to POST.  The latter is more secure and doesn't have the same character count restrictions.

I look forward to seeing the new IPN sample scripts so I can get a better understanding of exactly what you are proposing.

Just do this in PHP

$alertpay_raw_arr = $_POST;

$alertpay_arr = array_map("urldecode", $alertpay_raw_arr);

 

Any examples for decoding in a PERL script?
