passing var

[toryadams]

Ok quick run down... I need to pass a variable from one page[form] to another while skipping a page that is in the middle.

 

The middle page is paypal... after they pay, they are being redirected to a thank you for registering with a email also being sent.

But I need their email from the first page[form].

 

so what i need to figure out or help is:

 

1. First page is a form, they enter name, last name, address, email and so on

2. They are redirected to paypal to pay for a service.

3. Are directed back to my site for a email to be sent to them, but I need their email from the first page.

So just an update, I am going to attempt to pass a variable through the url to the paypal screen to the page it is needed on.

 

so the form will become self processing for the most part other than the email being sent out.

[toryadams]

passing the variable through paypal... did not work. Just had to try

[toryadams]

would a session be my best bet?

[MasterACE14]

you add the 'custom' field to the paypal button/form:

<input type='hidden' name='custom' value='yourvar' />

Then using their Instant Payment Notification (IPN) script that can be generated for PHP on their website you can get the variable on the other end.

[toryadams]

so just cause my mind is drawing a blank at this point been trying different things all day. In the text field for the value I want them to enter their email again or use a php tag there

 

<?php echo $_POST['email']; ?>

 

style?

[toryadams]

if anyone has used ipn on paypal help would be great...

 

Here is the code...

<?php
$connection = mysql_connect('testingblock.db.6607699.hostedresource.com', 'testingblock', 'KN1ght12') or die(mysql_error());
  	mysql_select_db("testingblock", $connection)or die(mysql_error());

$req = 'cmd=_notify-validate';

// go through each of the POSTed vars and add them to the variable
foreach ($_POST as $key => $value) {
$value = urlencode(stripslashes($value));
$req .= "&$key=$value";
}

// post back to PayPal system to validate
$header .= "POST /cgi-bin/webscr HTTP/1.0\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Content-Length: " . strlen($req) . "\r\n\r\n";

// In a live application send it back to www.paypal.com
// but during development you will want to uswe the paypal sandbox

// comment out one of the following lines

$fp = fsockopen ('www.sandbox.paypal.com', 80, $errno, $errstr, 30);
//$fp = fsockopen ('www.paypal.com', 80, $errno, $errstr, 30);

// or use port 443 for an SSL connection
//$fp = fsockopen ('ssl://www.paypal.com', 443, $errno, $errstr, 30);


if (!$fp) {

//email
$mail_From = "From: [email protected]";
$mail_To = $email;
$mail_Subject = "HTTP ERROR";
$mail_Body = $errstr;//error string from fsockopen

mail($mail_To, $mail_Subject, $mail_Body, $mail_From); 

// $fh = fopen("logipn.txt", 'a');//open file and create if does not exist
// fwrite($fh, "\r\n/////////////////////////////////////////\r\n HTTP ERROR \r\n");//Just for spacing in log file
//

here is the email i am getting

 

We have had an INVALID response.

 

The transaction ID number is:

 

username =

 

and i am using sandbox... so i did something wrong.

[toryadams]

so now the IPN is working fine, but I am needing to now pass my custom email input through paypal... problem is when using a buy now button it is like clicking a link so my email input the user is using does not pass through

[toryadams]

ok so my IPN script works now... I still am not able to recieve the email var i need on my generation page.

[Pikachu2000]

And you've opened another thread for that problem, correct?

[toryadams]

that was by accident. I am sorry about that... I was not paying attention when i hit new topic.

[Pikachu2000]

I'll go ahead and merge them to one thread then to keep the problem all together.

 

EDIT: Merge done . . .
