I am trying to integrate some code from my idevaffiliate software into my friendadder script site to track sales.

 

I need the following inserted into my paypal button code to do the tracking:

 

<input type="hidden" name="notify_url" value="http://www.friendspimp.com/idevaffiliate/paypal_ipn_buynow.php">
<input type="hidden" name="custom" value="<?PHP echo $_SERVER['REMOTE_ADDR']; ?>">

 

Also, I can leave the notify_url alone and just add the custom field to the paypal button, then use curl to post the ipn results to a second ipn script... that might be easier....

 

This is the script(3 pages control the process):

 

First page ppbuynow.php (I think this may be the only page that needs adjustment to get the echo of the IP address inserted into the button correctly. Line 71 looks to be my nemesis... and maybe my syntax is off in the other hacks I made.)

 

<?php
class PayPalBuyNow
{
    var $successUrl;
    var $notifyUrl;
    var $cancelUrl; 
    var $autoReturn;
    var $price;
    var $currency;
    var $email;
    var $item; 
    var $undefined_quantity;
    var $item_number;
    var $sandbox;
    var $no_note;
    var $no_shipping;
    var $charset;
    var $lc;
    #hack start
    var $custom;
    #hack end
    function PayPalBuyNow($item, $price, $success_url, $cancel_url, $email = false, $currency = false, $item_number = false, $undefined_quantity = false, $sandbox = null)
    {
        $app = getApp();
        $this->item = $item;
        $this->item_number = $item_number; 
        $this->undefined_quantity = $undefined_quantity; 
        $this->price = $price;
        $this->successUrl = $success_url;
        $this->cancelUrl = $cancel_url;
        $this->email = ($email === false) ? $app->getIni('Payments', 'paypal_email') : $email;
        $this->currency = ($currency === false) ? $app->getIni('Payments', 'paypal_currency') : $currency;
        $this->sandbox = ($sandbox === null) ? $app->getIni('Payments', 'paypal_sandbox') : $sandbox;
        #hack start
        #$this->notifyUrl = null;
        $this->notifyUrl = 'http://www.friendspimp.com/idevaffiliate.com/paypal_ipn_buynow.php';
        #hack end
        $this->no_note = false;
        $this->no_shipping = true;
        $this->charset = 'UTF-8'; 
        $this->lc = 'US';
        #hack start 
        $this->custom = 'IP_ADDRESS';
        #input type="hidden" name="custom" value="IP_ADDRESS"
        #hack end
    }
    function setLocation($location)
    {
        $this->lc = $location;
    }
    function setCharset($charset)
    {
        $this->lc = $charset;
    }
    function setNotifyUrl($url)
    {
        $this->notifyUrl = $url;
    }
    function setNoNote($value)
    {
        $this->no_note = $value;
    }
    function setNoShipping($value)
    {
        $this->$no_shipping = $value;
    }
    function getCode()
    {
        $return = urlencode($this->successUrl);
        $cancel = urlencode($this->cancelUrl); 
        return "https://www.".($this->sandbox ? 'sandbox.' : '')."paypal.com/cgi-bin/webscr?cmd=_xclick&business=".urlencode($this->email)."&item_name=".urlencode($this->item).(($this->item_number === false) ?

    }
}  
?>

I have made some changes indicated in the comments... I just don't seem to be getting this coding correct. I am a newbie in php so any help would be greatly appreciated and I will use this as a tutorial for making changes like this in the future. Also, I have some custom functions that I would like to add to this script in the future and will be looking for a 'go to' php/html/javascript guy to get this work done at a reasonable price in the future...

whoops I do see the error in the first file posted with the incorrect directory... /idevaffiliate.com/ should be /idevaffiliat/

 

I still can't seem to get this code to work, I also changed:

 

$this->custom = 'IP_ADDRESS';

 

To:

 

$this->custom = $_SERVER['REMOTE_ADDR'];

 

As this seems to make more sense as I just need to echo the IP of the user making purchase.

 

The problem I think lies in this section:

 

        return "https://www.".($this->sandbox ? 'sandbox.' : '')."paypal.com/cgi-bin/webscr?cmd=_xclick&business=".urlencode($this->email)."&item_name=".urlencode($this->item).(($this->item_number === false) ? '': "&item_number=".urlencode($this->item_number))."&amount=".urlencode($this->price)."&undefined_quantity=".($this->undefined_quantity ? '1' : '0')."&bn=".urlencode("VASoftOnline BuyNow PHP generator")."&return=$return".(($this->notifyUrl !== null) ? "&notify_url=".urlencode($this->notifyUrl) : '' )."&cancel_return=$cancel&currency_code=".urlencode($this->currency)."&no_shipping=".($this->no_shipping ? '1' : '0')."&no_note=".($this->no_note ? '1' : '0')."&charset=".urlencode($this->charset)."custom=".urlencode($this->custom);

 

I added the 'custom=' to the string, but I don't think that it is entirely correct nor incorrect either... lol.

 

Anyway, I would really love some help getting this to work!
