Their API takes a PHP array that looks something like this:</p> <pre><code>$d = new NgpDonation(&#39;your-credentials&#39;, true, array( &#39;FirstName&#39; =&gt; &#39;John&#39;, &#39;LastName&#39; =&gt; &#39;Doe&#39;, &#39;Address1&#39; =&gt; &#39;100 Elm Street&#39;, &#39;Zip&#39; =&gt; &#39;12345&#39;, &#39;Cycle&#39; =&gt; &#39;2012&#39;, &#39;Amount&#39; =&gt; &#39;50.00&#39;, &#39;CreditCardNumber&#39; =&gt; &#39;4111111111111111&#39;, &#39;ExpYear&#39; =&gt; &#39;13&#39;, &#39;ExpMonth&#39; =&gt; &#39;05&#39; ));</code></pre> <p>with many other possible fields. My code for validation is:</p> <pre><code>add_action(&quot;gform_validation&quot;, &quot;process_credit_card_data&quot;); /* * Courtsey of * <a href="http://www.newmediacampaigns.com/blog/accept-campaign-donations-with-the-ngp-contribution-api" rel="nofollow">http://www.newmediacampaigns.com/blog/accept-campaign-donations-with-the-ngp-contribution-api</a> * <a href="http://www.gravityhelp.com/documentation/page/Gform_validation" rel="nofollow">http://www.gravityhelp.com/documentation/page/Gform_validation</a> */ function process_credit_card_data($validation_result) { // print_r($form); // for debugging // print_r($validation_result); // print_r($_POST); if ($validation_result[&#39;is_valid&#39;]) { // cycle information $cycle = &#39;2012&#39;; /* ******************** General Web Contribute Form ******************** */ if (($validation_result[&#39;form&#39;][&#39;id&#39;] == 4)) { $source = &#39;ccOnline&#39;; // attempt payment -- being ready to reject if needed. // name information $firstName = rgpost(&quot;input_{$field[&#39;16&#39;]}&quot;); $lastName = rgpost(&quot;input_{$field[&#39;17&#39;]}&quot;); $email = rgpost(&quot;input_{$field[&#39;3&#39;]}&quot;); $phone = rgpost(&quot;input_{$field[&#39;4&#39;]}&quot;); // address information $address1 = rgpost(&quot;input_{$field[&#39;18&#39;]}&quot;); $address2 = rgpost(&quot;input_{$field[&#39;19&#39;]}&quot;); $city = rgpost(&quot;input_{$field[&#39;20&#39;]}&quot;); $state = rgpost(&quot;input_{$field[&#39;21&#39;]}&quot;); $zip = rgpost(&quot;input_{$field[&#39;22&#39;]}&quot;); // amount information $amountradio = rgpost(&quot;input_{$field[&#39;6&#39;]}&quot;); $amount = &#39;5&#39;; // credit card information $ccnum = rgpost(&quot;input_{$field[&#39;8&#39;]}&quot;); $exmonth = rgpost(&quot;input_{$field[&#39;9&#39;]}&quot;); $exyear = rgpost(&quot;input_{$field[&#39;10&#39;]}&quot;); // recurring information // $recurring = rgpost(&quot;input_11&#39;); // $recurringfreq = rgpost(&quot;input_12&#39;); // $recurringtotal = rgpost(&quot;input_13&#39;); // employment information $employer = rgpost(&quot;input_{$field[&#39;14&#39;]}&quot;); $occupation = rgpost(&quot;input_{$field[&#39;15&#39;]}&quot;); $result = do_transaction($lastName, $firstName, $email, $phone, $address1, $address2, $city, $state, $zip, $amount, $ccnum, $expMonth, $expYear, $employer, $occupation, $cycle, $source); if ($result !== true) { $validation_result[&#39;is_valid&#39;] = false; foreach($validation_result[&quot;form&quot;][&quot;fields&quot;] as &amp;$field){ if ($field[&quot;id&quot;] == &quot;8&quot;){ $field[&quot;failed_validation&quot;] = true; $field[&quot;validation_message&quot;] = $result; break; } } } else { // I like to blank credit card data so it&#39;s not stored locally. $_POST[&#39;input_8&#39;] = &#39;*****&#39;; } return $validation_result; /* ******************** End General Web Contribute Form ******************** */ } else { return $validation_result; } } else { return $validation_result; } } // This is the function that is called above function do_transaction($lastName, $firstName, $email, $phone, $address1, $address2, $city, $state, $zip, $amount, $ccnum, $exmonth, $exyear, $employer, $occupation, $cycle, $source) { require &#39;NgpDonation.php&#39;; // Your string goes below.

Am I pulling the variables incorrectly? Any help would be greatly appreciated. </p>
