osCommerce integration
A free online shop program featuring order history, shopping carts, full search capability, product reviews, secure transactions, bestseller lists, and related items.
Integration with osCommerce is made by placing sale tracking script into the confirmation page. To obtain the values of OrderID and TotalSale, snippet connects to osCommerce database and retrieves the values from there.
Find file checkout_success.php
Find and open file checkout_success.php in osCommerce source files.
Locate right place for integration
Inside the file find this line:
if ($global['global\_product\_notifications'] != '1') {...
it should be somewhere after this line:
<! DOCTYPE ........>Add integration code
Insert the following code just above that line:
//--------------------------------------------------------------------------
// integration code
//--------------------------------------------------------------------------
// get order id
$sql = "select orders_id from ".TABLE_ORDERS.
" where customers_id='".(int)$customer_id.
"' order by date_purchased desc limit 1";
$pap_orders_query = tep_db_query($sql);
$pap_orders = tep_db_fetch_array($pap_orders_query);
$pap_order_id = $pap_orders['orders_id'];
// get total amount of order
$sql = "select value from ".TABLE_ORDERS_TOTAL.
" where orders_id='".(int)$pap_order_id.
"' and class='ot_subtotal'";
$pap_orders_total_query = tep_db_query($sql);
$pap_orders_total = tep_db_fetch_array($pap_orders_total_query);
$pap_total_value = $pap_orders_total['value'];
//get product ids
$sql = "select products_id from " .TABLE_ORDERS_PRODUCTS.
" where orders_id=".(int)$pap_order_id;
$pap_orders_products_query = tep_db_query($sql);
$pap_orders_products = '';
while ($row = tep_db_fetch_array($pap_orders_products_query)) {
$pap_orders_products .= $row['products_id'] . ',';
}
$pap_orders_products = substr($pap_orders_products, 0, -1);
// draw invisible image to register sale
if($pap_total_value != "" && $pap_order_id != "")
{
print '<script id="pap_x2s6df8d" src="https://URL_TO_PostAffiliatePro/scripts/trackjs.js" type="text/javascript"></script>
'."<script type=\"text/javascript\">PostAffTracker.setAccountId('Account_ID');
var sale = PostAffTracker.createSale();
sale.setTotalCost('$pap_total_value');
sale.setOrderID('$pap_order_id');
sale.setProductID('$pap_orders_products');
PostAffTracker.register();
</script>";
}
//--------------------------------------------------------------------------
// END of integration code
//--------------------------------------------------------------------------
Integration is finished
It is now integrated. Every time customer enters the order confirmation page the tracking code is called and it will register a sale for referring affiliate.
Another integration
If you plan to divide products into more campaigns, you will probably need another integration, that will divide the whole sale into single product sales.
//--------------------------------------------------------------------------
// integration code
//--------------------------------------------------------------------------
// get order id
$sql = "select orders_id from ".TABLE_ORDERS.
" where customers_id='".(int)$customer_id.
"' order by date_purchased desc limit 1";
$pap_orders_query = tep_db_query($sql);
$pap_orders = tep_db_fetch_array($pap_orders_query);
$pap_order_id = $pap_orders['orders_id'];
//get variables for script
$sql = "select products_id,products_price,products_quantity from " .TABLE_ORDERS_PRODUCTS.
" where orders_id=".(int)$pap_order_id;
$pap_products_total_query = tep_db_query($sql);
$k = 0;
while ($row = tep_db_fetch_array($pap_products_total_query)) {
$pap_products_total[$k+1] = $row['products_price'] * $row['products_quantity'];
$pap_products[$k+1] = $row['products_id'];
$k++;
}
// draw invisible image to register sale
if($pap_order_id != "")
{
?>
<script id="pap_x2s6df8d" src="https://URL_TO_PostAffiliatePro/scripts/trackjs.js" type="text/javascript"></script>
<script type="text/javascript">
PostAffTracker.setAccountId('Account_ID'); <?php
for ($j=1; $j<=$k; $j++){
echo "var sale".$j." = PostAffTracker.createSale();\n".
"sale".$j.".setTotalCost('". $pap_products_total[$j]."');\n".
"sale".$j.".setOrderID('".$pap_order_id."');\n".
"sale".$j.".setProductID('".$pap_products[$j]."');\n\n";
}

PostAffTracker.register();
</script>;

Direct PayPal integration with osCommerce
If you want to rely on PayPal IPN (as this is secure and 100% sure that the transaction will be recorded), you can directly edit the PayPal button template in osCommerce. Login to your FTP and navigate to catalog/includes/modules/payment/ and edit file paypal_standard.php.
Find function process_button and scroll down to end of it. You should find this block of code:
} else {
reset($parameters);
while (list($key, $value) = each($parameters)) {
$process_button_string .= tep_draw_hidden_field($key, $value);
}
}
return $process_button_string;
// --------------------------------------------
// change this whole block of code to this block:
} else {
reset($parameters);
while (list($key, $value) = each($parameters)) {
if ($key == "custom") {
$tofix = tep_draw_hidden_field($key, $value);
$process_button_string .= substr($tofix,0,-1) .' id="pap_ab78y5t4a" >';
}
else {
$process_button_string .= tep_draw_hidden_field($key, $value);
}
}
}
$process_button_string .= '<script type="text/javascript">';
$process_button_string .= 'document.write(unescape("%3Cscript id=%27pap_x2s6df8d%27 src=%27" + (("https:" == document.location.protocol) ? "https://" : "http://") + "URL_TO_PostAffiliatePro/scripts/trackjs.js%27 type=%27text/javascript%27%3E%3C/script%3E"));';
$process_button_string .= '</script><script type="text/javascript">PostAffTracker.setAccountId(\'default1\');';
$process_button_string .= 'PostAffTracker.setAppendValuesToField(\'||\');';
$process_button_string .= 'PostAffTracker.writeCookieToCustomField(\'pap_ab78y5t4a\');</script>';
return $process_button_string;
This will add tracking script directly to the paypal button and insert proper value into custom parameter.
Now, you have to resend the IPN from osCommerce to PAP too. See the next step.
PayPal redirect to PAP
When there is a sale, PayPal sends IPN to your osCommerce. You have to resend it to PAP to save the transaction. Navigate to catalog/ext/modules/payment/paypal/ in your FTP and modify file standard_ipn.php . Insert the following code to the beginning of the file:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://URL_TO_PostAffiliatePro/plugins/PayPal/paypal.php");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $_POST);
curl_exec($ch);
The last step is to modify customer ID saved in custom field, to the the value without PAP visitor ID. Find line:
if ($result == 'VERIFIED') {
and add the following code above the line:
$separator = '||';
if ($_POST['custom'] != '') {
$explodedCustomValue = explode($separator, $_POST['custom'], 2);
if (count($explodedCustomValue) == 2) {
$_REQUEST['custom'] = $_POST['custom'] = $explodedCustomValue[0];
$HTTP_POST_VARS['custom'] = $explodedCustomValue[0];
}
}
Do not forget to integrate your website with the click tracking code.
