foreach ($_POST as $key=>$value)

Hello,

 

Below is a php code i am writing on an ubuntu server using VNC.

 

as shown in the attached when i run the php code, its saying that newcontent is undefined. We figured out that the problem is related to the fact that the code is not entering the loop foreach ($_POST as $key=>$value).

 

I would really appreciate your help.

 

please note that the below code is used to validate apple IAP receipt through a dedicated server.

 

 

<?php

function getReceiptData($receipt)

{

$fh = fopen('showme.txt',w);

fwrite($fh,$receipt);

fclose($fh);

$endpoint = 'https://sandbox.itunes.apple.com/verifyReceipt';

 

$ch = curl_init($endpoint);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

curl_setopt($ch, CURLOPT_POST, true);

curl_setopt($ch, CURLOPT_POSTFIELDS, $receipt);

$response = curl_exec($ch);

$errno = curl_errno($ch);

$errmsg = curl_error($ch);

curl_close($ch);

$msg = $response.' - '.$errno.' - '.$errmsg;

echo $response;

}

 

foreach ($_POST as $key=>$value){

$newcontent .= $key.' '.$value;

}

 

$new = trim($newcontent);

$new = trim($newcontent);

$new = str_replace('_','+',$new);

$new = str_replace(' =','==',$new);

 

if (substr_count($new,'=') == 0){

if (strpos('=',$new) === false){

$new .= '=';

}

}

 

$new = '{"receipt-data":" '. $new ' "}';

$info = getReceiptData($new);

?>

If it's not entering the loop then $_POST must be empty. Either the request to your script is not a POST request or no data was submitted.

 

You can fix your undefined error by initializing $newcontent above the loop, but if you're expecting data you'll have to look into why you're not getting it.

$newcontent = '';
foreach ($_POST as $key=>$value){
   $newcontent .= $key.' '.$value;
}

side note: In the future, surround your code with

tags when posting, it makes it easier to read and preserves spacing.

Also - you should always show the EXACT error message and the line number and POINT out to us where that line is.  That could help in solving this very problem.
