php - Mailchimp double_optin option not working -

-

i've followed this tutorial implement mailchimp api v2.0 on website. works great, double_optin option wanted add , set false (so users don't need validate registration via e-mail) doesn't seem working. it's if not taken consideration @ all, users still need validate registration via e-mail.

is 'double_optin' => false placed @ wrong place? had @ mailchimp documentation level in programmation not enough identify wrong. help

<?php $api_key = "12345486-us8";  $list_id = "123";  require('mailchimp.php'); $mailchimp = new mailchimp( $api_key ); $mailchimp_lists = new mailchimp_lists( $mailchimp ); $subscriber = $mailchimp_lists->subscribe( $list_id, array( 'email' => htmlentities($_post['email']),'double_optin' => false ) );  if ( ! empty( $subscriber['leid'] ) ) {    echo "success"; } else {     echo "fail"; }  ?>

according (admittedly unofficial-looking) mailchip_lists documentation, you'll want pass false 5th parameter subscribe().

example:

$double_optin = false;  $subscriber = $mailchimp_lists->subscribe(     $list_id,     array('email' => htmlentities($_post['email'])),     null, // merge_vars     'html', // email_type     $double_optin );
