Question

This is driving me nuts because I’m being sent a form post that includes a name-value pair that looks like this:

&transaction[0].id=5TH49195SG993903B

In my php receiver file I’m trying to get the value thusly:

$txnid =  $_POST["transaction[0].id"];

Yet it comes in blank every time. This is from a paypal IPN transmission. I’m not tagging this question for paypal because I don’t think it’s related to paypal. I can log into paypal and see what they say is the form post, so evidently they are sending that (along with lots of other values).

Am I making some kind of stupid mistake? I’m thinking this has something to do with the [0] indexer because I can successfully get other form values in this same POST, when they don’t have an indexer on them. Such as:

$buyer_email =  $_POST["sender_email"];

What am I doing wrong?

Answer 1

if you try var_dump($_POST) you will get output like this:

array(1) { ["transaction"]=> array(1) { [0]=> string(17) "5TH49195SG993903B" } } 

Therefore in order to catch that param you need to use $_POST['transaction'][0];
