Hey all,

I cant find any info on how to get use the paypal ipn to create a webuser account.

I have set up a button for a subscription and it returns to a php file the code looks like this (I found it in a tute)

<?php
/*
Simple IPN processing script
based on code from the "PHP Toolkit" provided by PayPal
*/

$url = 'https://www.paypal.com/cgi-bin/webscr';
$postdata = '';
foreach($_POST as $i => $v) {
	$postdata .= $i.'='.urlencode($v).'&';
}
$postdata .= 'cmd=_notify-validate';

$web = parse_url($url);
if ($web['scheme'] == 'https') { 
	$web['port'] = 443;  
	$ssl = 'ssl://'; 
} else { 
	$web['port'] = 80;
	$ssl = ''; 
}
$fp = @fsockopen($ssl.$web['host'], $web['port'], $errnum, $errstr, 30);

if (!$fp) { 
	echo $errnum.': '.$errstr;
} else {
	fputs($fp, "POST ".$web['path']." HTTP/1.1\r\n");
	fputs($fp, "Host: ".$web['host']."\r\n");
	fputs($fp, "Content-type: application/x-www-form-urlencoded\r\n");
	fputs($fp, "Content-length: ".strlen($postdata)."\r\n");
	fputs($fp, "Connection: close\r\n\r\n");
	fputs($fp, $postdata . "\r\n\r\n");

	while(!feof($fp)) { 
		$info[] = @fgets($fp, 1024); 
	}
	fclose($fp);
	$info = implode(',', $info);
	if (eregi('VERIFIED', $info)) { 
		// yes valid, f.e. change payment status  
		
	}
	} else {
		// invalid, log error or something
	}
}
?>

I am looking to put some code into the "// yes valid, f.e. change payment status" that pulls in the paypal data like payer_email password and username, as well as set the new user to a specific document group.

Anyone done this before?

Thanks!

So for the connect to modx database part I found this:

http://www.flashgoddess.com/forum/viewtopic.php?t=1419

But it wont connect?

I double checked my logins as well.

Does a modx database need some other type of connect?

If you convert this script to a snippet in a page within MODx, you will have access to the MODx db connection and the MODx object.

Thanks,

If I do this will paypal still be able to use the page as a IPN?

Yes, there’s really no difference between this as a standalone script or as a snippet in MODx, other than you should return the output rather than echo()’ing it.

Thanks Okay I have got it working except I am not sure on how to set this new user to a web user group?

Here is my code so far (I havent put in the paypal place holders yet, still testing).

<?php
$web_users = $modx->getFullTableName('web_users');
$web_user_attributes = $modx->getFullTableName('web_user_attributes');
$web_groups = $modx->getFullTableName('web_groups');

$username = "mat1";
$password = "guest";
$cachepwd = time();

$newUser = "INSERT INTO ".$web_users." (`username`, `password`, `cachepwd`) VALUES ('".$username."', '".md5($password)."', '".$cachepwd."')";
$createNewUser = $modx->db->query($newUser);

$key = $modx->db->getInsertId();
$NewUser['internalKey'] = $key;

$newUserAttr = "INSERT INTO ".$web_user_attributes.
" (internalKey, fullname, email, phone, mobilephone, dob, gender, country, state, zip, fax, photo, comment) VALUES".
" ('".$key."', '".$fullname."', '".$email."', '".$phone."', '".$mobilephone."', '".$dob."', '".$gender."', '".$country."', '".$state."', '".$zip."', '".$fax."', '".$photo."', '".$comment."')";
$insertUserAttr = $modx->db->query($newUserAttr);
?>

Its basically a cut and past from webloginPE.

So the question is how do I set this new user to a group called ’web users’?

Maybe something like this?

$webGroupId = "web users";
$modx->db->query("REPLACE INTO ".$web_groups." (`webgroup`, `webuser`) VALUES ('".$webGroupId."', '".$key."')");

Hey I figured out the above.

But now when I test it through paypal it doesnt look as if it is going to this page with the ipn code?

Hi,
I have a similar issue. I can use Paypal IPN script if it refers to a php script posted on the web server but when I include the same script in a snippet and I use the notify_url to point to a MODx document including this snippet I get a 503 error and paypal tries to resent it.
OpenGeek seems to mention that it should work. Has any tried to invoke a modx document using paypal ipn?
Thanks in advance for your help.

<input type="hidden" name="notify_url" value="http://test.com/notify_ipn">

Hey Guys,

Almost there.

I need my ipn to delete a user.

Here is what the webloginPE has to delete accounts:

function RemoveProfile($internalKey)
{
global $modx;
$deletedUser = $modx->getWebUserInfo($internalKey);
$web_users = $modx->getFullTableName(’web_users’);
$web_user_attributes = $modx->getFullTableName(’web_user_attributes’);
$web_groups = $modx->getFullTableName(’web_groups’);
$active_users = $modx->getFullTableName(’active_users’);

$deleteUser = $modx->db->query("DELETE FROM ".$web_users." WHERE `id`=’".$internalKey."’");
$deleteAttributes = $modx->db->query("DELETE FROM ".$web_user_attributes." WHERE `internalKey`=’".$internalKey."’");
$deleteFromGroups = $modx->db->query("DELETE FROM ".$web_groups." WHERE `webuser`=’".$internalKey."’");
$deleteFromActiveUsers = $modx->db->query("DELETE FROM ".$active_users." WHERE `internalKey`=’-".$internalKey."’");

if (!$deleteUser || !$deleteAttributes || !$deleteFromGroups || !$deleteFromActiveUsers)
{
return $this->FormatMessage($this->LanguageArray[13]);
}
$this->OnWebDeleteUser($internalKey, $deleteUser[’username’]);
return;
}

How could I modify this to delete a user based on the paypal email?

Thanks

So I need to get the ’internalKey’ value from the users table, I figure I need to loop through the $web_user_attributes table then when the paypal email matches a stored email then set $internalKey to that users ’internalKey’.

This is what I have so far.
It works if I put in the ’internalKey’ manually.

<?php
//delete user

$web_users = $modx->getFullTableName(’web_users’);
$web_user_attributes = $modx->getFullTableName(’web_user_attributes’);
$web_groups = $modx->getFullTableName(’web_groups’);
$active_users = $modx->getFullTableName(’active_users’);

$email = "[email protected]"; //this will be a paypal email

$checkEmail = $modx->db->query("SELECT * FROM ".$web_user_attributes." WHERE `email`=’".$email."’");
$limit = $modx->recordCount($checkEmail);
if ($limit > 0)
{
$internalKey = $checkEmail[’internalKey’];
}

echo "<script>alert(’$internalKey’);</script>";

$deleteUser = $modx->db->query("DELETE FROM ".$web_users." WHERE `id`=’".$internalKey."’");
$deleteAttributes = $modx->db->query("DELETE FROM ".$web_user_attributes." WHERE `internalKey`=’".$internalKey."’");
$deleteFromGroups = $modx->db->query("DELETE FROM ".$web_groups." WHERE `webuser`=’".$internalKey."’");
$deleteFromActiveUsers = $modx->db->query("DELETE FROM ".$active_users." WHERE `internalKey`=’-".$internalKey."’");
?>
