Wordpress Contact Form 7 manually add Aweber subscribers in PHP

Add this function to the Contact Form 7 functions.php file in the /wp-content/plugins/contact-form-7/includes folder.

Works with Contact Form 7 v3.9 upwards

Change the details to your Aweber list name, meta ad tracking, form id etc. The redirect and redirect_onlist doesn't actually go the page specified (can be removed if you like)

Note: the user still has to confirm the subscription via email to be successfully added to the Aweber list

function process_aweber($cf7) {

$submission = WPCF7_Submission::get_instance();

if ( $submission ) {
$name = $_POST['your-name'];
$email = $_POST['your-email'];

$str=
'meta_web_form_id='.urlencode('000000000').
