Awarding Commission via HTTP GET or POST – Problems to make it work

[mreddie]

Hi,

I have problems to make WP Affiliate Platform work on my blog. My wordpress version is 3.0.5 and the WP Affiliate Platform is 4.7.1. My shoping cart system is WP Shop Germany (a popular German WP shopping system) written in PHP. Her’s an example product page of my blog: http://www.driediger.de/menowin-froehlich-biografie-ich-musste-verlieren-um-zu-gewinnen/

I’ve followed your instructions from this documentation page:

http://www.tipsandtricks-hq.com/wordpress-affiliate/awarding-commission-via-http-get-or-post-189

I’ve integrated the mentioned PHP-example code as instructed on the thank you page of the shopping cart and performed some tests. The affiliate platform just counts the clicks, but there is no commission awarding and the sales count is always “0”.

I’m really frustrated especially because I don’t know what I’m doing wrong. It would be nice if you could give me some additional instructions to make it work.

To make it clearer what I’ve done here’s the exact code of my “Thank You page”. The “Thank You Page” (do.phtml) appears when the costumer clicks the order (bestellen) button on the checkout overview. The costumer makes the payment manually after recieving the product invoice. So here’s the code:

<?php

/*

Dieses Template wird nach Abschluss einer Bestellung angezeigt. Es können folgende Platzhalter verwendet werden.

<?php echo $this->order_id; ?> Returns the orderID

<?php echo $this->k_id; ?> Returns the costumerID

<?php echo $this->order_data; ?> Returns the sale amount

Auf die bestellten Produkte können sie mittels $this->basket zugreifen.

<?php echo sizeof($this->basket); ?> Returns the number of ordered products

<?php echo $this->basket[1]; ?> Returns 1st productID

<?php echo $this->basket[1]; ?> Returns the ordered amount of 1st product

<?php echo $this->basket[1]; ?> Price of 1st product

*/

?>

<div class=”wpshopgermany”>

<h2><?php echo __(“Schritt 5 von 5: Abschluss der Bestellung”, “wpsg”); ?></h2>

<?php if ($this->failed) { ?>

<h2><?php echo __(“Die Bestellung konnte nicht durchgeführt werden.”, “wpsg”); ?></h2>

<?php } else { ?>

<h2><?php echo __(“Vielen Dank für Ihre Bestellung”, “wpsg”); ?></h2>

<p><?php echo __(“Ihre Bestellung ist erfolgreich in unserem System eingegangen und wird bearbeitet. Vielen Dank für Ihr Vertrauen.”, “wpsg”); ?></p>

<?php

// The sale amount. You get this value from your payment gateway or the shopping cart

$sale_amt = $this->order_data;

echo $sale_amt;

// The Post URL (Get this value from the settings menu of this plugin)

$postURL = “http://www.driediger.de/wp-content/plugins/wp-affiliate-platform/api/post.php&#8221;;

echo $postURL;

// The Secret key (Get this value from the settings menu of this plugin)

$secretKey = “4e09fc1de376d”;

echo $secretKey;

// Retrieve the value from the browser’s cookie to find out who the referrer was

$affiliate_id = $_COOKIE;

echo $affiliate_id;

// Prepare the data

$data = array ();

$data = $secretKey;

$data = $affiliate_id;

$data = $sale_amt;

// send data to post URL to award the commission

$ch = curl_init ($postURL);

curl_setopt ($ch, CURLOPT_POST, true);

curl_setopt ($ch, CURLOPT_POSTFIELDS, $data);

curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);

$returnValue = curl_exec ($ch);

curl_close($ch);

?>

<?php } ?>

<?php foreach ($this->modText as $t) { echo $t; } ?>

</div>

Any ideas to solve this problem?

Thx in advance for your support.

We just need to debug it a little and find out what is missing.

Can you please tell me the the output that you get from the lines of code where you added an “echo” statement?

$sale_amt = $this->order_data['price_gesamt'];

echo $sale_amt;

// The Secret key (Get this value from the settings menu of this plugin)

$secretKey = "4e09fc1de376d";

echo $secretKey;

// Retrieve the value from the browser's cookie to find out who the referrer was

$affiliate_id = $_COOKIE['ap_id'];

echo $affiliate_id;

Also, pease add the following line immediately after the $returnValue = curl_exec ($ch); line which should print out some more details:

print_r($returnValue);

After the above modification please do a test and let me know what output you get from it.

Also, if you enable the debug by checking the “Enable Debug” checkbox from the settings menu of the affiliate plugin it will write a log file (aff_commission_post_debug.log) that will have more info for as to what it did when it received the request from your thank you page.

Thx for your quick reply.

I’ve performed the above instructions. Here’s the “new” code of the “Thank You Page” after modification:

<?php

/*

Dieses Template wird nach Abschluss einer Bestellung angezeigt. Es können folgende Platzhalter verwendet werden.

<?php echo $this->order_id; ?> Returns the orderID

<?php echo $this->k_id; ?> Returns the costumerID

<?php echo $this->order_data; ?> Returns the sale amount

Auf die bestellten Produkte können sie mittels $this->basket zugreifen.

<?php echo sizeof($this->basket); ?> Returns the number of ordered products

<?php echo $this->basket[1]; ?> Returns 1st productID

<?php echo $this->basket[1]; ?> Returns the ordered amount of 1st product

<?php echo $this->basket[1]; ?> Price of 1st product

*/

?>

<div class=”wpshopgermany”>

<h2><?php echo __(“Schritt 5 von 5: Abschluss der Bestellung”, “wpsg”); ?></h2>

<?php if ($this->failed) { ?>

<h2><?php echo __(“Die Bestellung konnte nicht durchgeführt werden.”, “wpsg”); ?></h2>

<?php } else { ?>

<h2><?php echo __(“Vielen Dank für Ihre Bestellung”, “wpsg”); ?></h2>

<p><?php echo __(“Ihre Bestellung ist erfolgreich in unserem System eingegangen und wird bearbeitet. Vielen Dank für Ihr Vertrauen.”, “wpsg”); ?></p>

<?php

// The sale amount. You get this value from your payment gateway or the shopping cart

$sale_amt = $this->order_data;

echo $sale_amt;

// The Post URL (Get this value from the settings menu of this plugin)

$postURL = “http://www.driediger.de/wp-content/plugins/wp-affiliate-platform/api/post.php&#8221;;

echo $postURL;

// The Secret key (Get this value from the settings menu of this plugin)

$secretKey = “4e09fc1de376d”;

echo $secretKey;

// Retrieve the value from the browser’s cookie to find out who the referrer was

$affiliate_id = $_COOKIE;

echo $affiliate_id;

// Prepare the data

$data = array ();

$data = $secretKey;

$data = $affiliate_id;

$data = $sale_amt;

// send data to post URL to award the commission

$ch = curl_init ($postURL);

curl_setopt ($ch, CURLOPT_POST, true);

curl_setopt ($ch, CURLOPT_POSTFIELDS, $data);

curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true);

$returnValue = curl_exec ($ch);

print_r($returnValue);

curl_close($ch);

?>

<?php } ?>

<?php foreach ($this->modText as $t) { echo $t; } ?>

</div>

After a test-order (the sale amount was €12,90, the test-affiliateID is “mreddie”, the secretKey is “4e09fc1de376d”) I got this results:

A screenshot of the “Thank You Page” after the test:

This is the output of the “aff_commission_post_debug.log”-file after the test:

Thank you for the debug info. I can see the issue now. The mistake is in the following line:

$data['secret_key'] = $secretKey;

Please change it to the following and that should do it:

$data['secret'] = $secretKey;

[mreddie]

Thank you for your quick support. You saved my day!!!

Everything’s fine now!!!

Regards,

Eddie
