PayPal donations tracking

Very, very basic donations tracking for the Defitech website:

• PayPal IPN listener page (source/paypal_notify) logging notifications and adding donations per campaign (i.e. PayPal API's item_number)
• Totals per campaign are stored in simple text files

Example usage

In PayPal (e.g. 'Donate' button setup), configure the desired campaign id and set the IPN listener URL to where you published paypal_notify.php. On your webpage, require donations.php and retrieve the current donations total with Donations::getTotal.

E.g. this displays the total for campaign {campaign id} and displays a basic progress bar:

<div id="fundraising-status">
  <?php
require("{path to donations.php}");
$total = Donations::getTotal("{campaign id}");
$goal = 10000;
$percentage = min(round($total / $goal * 100, 2), 100);
  ?>
  <div id="fundraising-progress">
    <div id="fundraising-progress-percentage" style="width: <?php echo $percentage . "%"; ?>;">
    </div>
    <div id="fundraising-progress-text">
      <?php echo round($total, 2); ?> contributed
    </div>
  </div>
</div>

Testing

php test/donations.test.php

Deploying
