Help With gform_after_submission

I was wondering if someone can help me to understand how the gform_after_submission works.

I created a sample Gravity Form with the id gform_1
I added one Text Field <input name="input_1" id="input_1_1" type="text" value="" class="medium" tabindex="1">

To have that text fields info passed to a php scrict called dataprocess.php I added this to my functions.php file:

<?php
add_action('gform_after_submission_1', 'post_to_third_party', 10, 2);
function post_to_third_party($entry, $form) {

    $post_url = 'dataprocess.php';
    $body = array(
        'bname' => $entry['input_1_1'],
        );

    $request = new WP_Http();
    $response = $request->post($post_url, array('body' => $body));

}
?>

In my dataprocess.php I added:

<?php
$bname = $_POST['bname'];
echo "Hello " . $bname . "";
?>

Should the form automatically redirect me to the dataprocess.php or do I need to setup the redirect and are the variables correct the way I am using them. I don't seem to get the php file to echo anything back to me.

Thanks for any help

Hi David,

Thank you for your reply. What I am trying to do is pass information from a gravity form to the First Data Payment Gateway.

The Payment Gateway requires certain field names to be passed like bname, baddr1, bcity, etc..

My thoughts were to use the gform_after_submission to pass the info to a php script and make the required changes and submit the data from there to the payment gateway.

I was not really sure of the actual process and whether I could accomplish this with the hook or not.

I think adding it to the functions.php makes good sense if I can get some assistance in understanding the correct way to use the hook to change the field names I may be able to make it work.

Thanks again for your assistance.

So the field name I need to pass is bname I would use:

'bname' => $entry[1] . ' ' . $entry[2] );

the $post_url = 'http://yourthirdparty.com/path/to/api/' would be the url to the paypent gateway

Do the numbers for the $entry change to $entry[input_1_1] ? I am not sure where the 1 and 2 are coming from.

After some more testing I am getting closer put things still don't seem to be working right.

I am able to get the correct data from the fields and place them in the array with the key being the field name required by the payment gateway.

~add_action('gform_after_submission_4', 'post_to_third_party', 10, 2);
function post_to_third_party($entry, $form) {

$post_url = 'https://www.linkpointcentral.com/lpc/servlet/lppay';

$body = array(
'bname' => $entry['10'], 'baddr1' => $entry['2.1'] );

$request = new WP_Http();
$response = $request->post($post_url, array('body' => $body));
}~

How can I pass these variables and redirect the way a form would redirect to the payment gateway.

Thanks again for your assistance.

I do know if I echo $response it just says Array

Okay, I've figured out why #gf_2 was appended to the URL -- it's because I was testing from the Form Preview instead of from the page that the form is on. Duh.

But testing from the form on the published page still results in no post variables being passed, as far as I can tell.

Here's the problem as I see it: I need to submit the main registration form to a redirect page which then sends the form to either a financial aid form or the payment gateway. I can't use GET variables because I need to specify the URLs on the redirect page. So I need to pass POST variables. That seems to mean that I need to use the gform_after_submission post_to_third_party function in the Documentation here:
http://www.gravityhelp.com/documentation/page/Gform_after_submission
But I can't get the $body array variables to pass.

On my test site, I've tried ditching the redirect page and submitting the form to a page on my own test site where I can ask for variables and check whether they're coming through. But they're not. Adding
print_r ($result['response']);
to the function results in nothing.

A GET variable comes through okay, but that doesn't work for a redirect page, as detailed above.

Sometimes I can catch this:
Array ( [chargetotal] => 32 [mode] => Fullpay [storename] => 1001294132 [txntype] => sale )
but I don't know what to do with it :)
