[system]

I am lost. I found some php that i integrated to a wordpress template page and can not get it to submit to the ConstantContact DB. Would someone be willing to help?

[php]<?php get_header(); ?>

		<article class="entry clearfix">
		<?php
			the_content();

			wp_link_pages( array( 'before' => '<div class="page-links">' . __( 'Pages:', 'Vertex' ), 'after' => '</div>' ) );
		?>

			<div id="et-contact" class="responsive">

<?php if ( ! isset( $_SESSION ) ) session_start(); /* Template Name: Constant Contact */ ?> <?php // require the autoloader require_once('../html/wp-content/themes/Vertex/Ctct/autoload.php'); //verified files are all there use Ctct\ConstantContact; use Ctct\Components\Contacts\Contact; use Ctct\Components\Contacts\ContactList; use Ctct\Components\Contacts\EmailAddress; use Ctct\Exceptions\CtctException; // Enter your Constant Contact APIKEY and ACCESS_TOKEN define("APIKEY", "KEY ID"); //verified both key and token define("ACCESS_TOKEN", "TOKEN ID"); $cc = new ConstantContact(APIKEY); // attempt to fetch lists in the account, catching any exceptions and printing the errors to screen - works try { $lists = $cc->getLists(ACCESS_TOKEN); } catch (CtctException $ex) { foreach ($ex->getErrors() as $error) { print_r($error); } } // check if the form was submitted if (isset($_POST['email']) && strlen($_POST['email']) > 1) { $action = "Getting Contact By Email Address"; try { // check to see if a contact with the email addess already exists in the account $response = $cc->getContactByEmail(ACCESS_TOKEN, $_POST['email']); // create a new contact if one does not exist if (empty($response->results)) { $action = "Creating Contact"; $contact = new Contact(); $contact->addEmail($_POST['email']); $contact->addList($_POST['list']); $contact->first_name = $_POST['first_name']; $contact->last_name = $_POST['last_name']; /* * The third parameter of addContact defaults to false, but if this were set to true it would tell Constant * Contact that this action is being performed by the contact themselves, and gives the ability to * opt contacts back in and trigger Welcome/Change-of-interest emails. * * See: http://developer.constantcontact.com/docs/contacts-api/contacts-index.html#opt_in */ $returnContact = $cc->addContact(ACCESS_TOKEN, $contact, true); // update the existing contact if address already existed } else { $action = "Updating Contact"; $contact = $response->results[0]; $contact->addList($_POST['list']); $contact->first_name = $_POST['first_name']; $contact->last_name = $_POST['last_name']; /* * The third parameter of updateContact defaults to false, but if this were set to true it would tell * Constant Contact that this action is being performed by the contact themselves, and gives the ability to * opt contacts back in and trigger Welcome/Change-of-interest emails. * * See: http://developer.constantcontact.com/docs/contacts-api/contacts-index.html#opt_in */ $returnContact = $cc->updateContact(ACCESS_TOKEN, $contact, true); } // catch any exceptions thrown during the process and print the errors to screen } catch (CtctException $ex) { echo 'Error ' . $action .

After hitting submit I get a screen that says no page exists… which I understand as that page does not exist…
This is where I got the code to use.

constantcontact/php-sdk/blob/development/examples/addOrUpdateContact.php

should I call the same page that users entered their data on? How do I make this work?
