PayPal helper libraries for PHP

PayPal Library

This is a PHP library for building applications that use PayPal. It contains classes to help deal with IPN requests, PDT requests and generating PayPal buttons.

IPN Requests

PayPal IPN and PDT Variables Reference.

<?php
$ipn = new PayPal\IpnRequest;
$ipn->set_timeout(5);
$ipn->allow_test_ipns(true);

$ipn->process(function($post_data) {
  // Save it to the database or something
});

PDT Requests

PayPal IPN and PDT Variables Reference.

<?php
$pdt = new PayPal\PdtRequest($paypal_pdt_token);
$pdt->set_timeout(5);
$pdt->allow_sandbox(true);

$pdt->process(function($transaction_data) {
  // Show the user a receipt
}, function() {
  // Validation failed, show the user an error message or pull their receipt
  // from your database. Validation will fail after 3-5 successful verification
  // attempts.
})

PayPal Buttons

<?php
$button = new PayPal\EncryptedButton;
$button->set_certificate($your_public_cert, $your_private_key);
$button->set_certificate_id($paypal_cert_id);
$button->set_paypal_cert($paypal_public_cert);
$encrypted_text = $button->encrypt([
  'cmd'           => '_xclick',
  'business'      => '[e-mail]',
  'lc'            => 'CA',
  'currency_code' => 'CAD',
  'no_shipping'   => '1',
  'no_note'       => '1',
  'custom'        => 'some_custom_data',
  'item_name'     => 'An Awesome Item',
  'amount'        => '123.45',
  'quantity'      => '1',
  'item_number'   => 'AWESOME-ITM-01',
  'tax'           => '0.00'
]);
?>
<form method="post" action="https://www.paypal.com/cgi-bin/webscr">
  <input type="hidden" name="cmd" value="<?= $button->get_cmd() ?>">
  <input type="hidden" name="encrypted" value="<?= $encrypted_text ?>">
  <input type="submit" value="Checkout">
</form>
