Simple e-mail confirmation plugin for WordPress.

Email Confirmation for WordPress

Send an email to the user with confirmation code and store form data in database until user confirms.

Requires: PHP 5.3+

How To


Drop the plugin in /wp-content/plugins/email-confirmation and activate in WordPress.


Make sure to validate all your data before using Email Confirmation, then you can call the plugin anywhere in your templates:

$headers = 'From: admin <noreply@admin>';
$to = $_POST['email'];
$subject = 'Confirm';
// The unique token can be inserted in the message with %s
$message = 'Thank you. Please <a href="<?= home_url('confirm') ?>?token=%s">confirm</a> to continue';

if ($isAllValid) {
  EmailConfirmation::send($to, $subject, $message, $headers);

The above will send an email with a unique token for confirmation and store the $_POST array in the DB.

The confirmation link can be any page or template you want. For a minimal setup all you need is to pass the token in $_GET. The check method will retrieve the data for a specific token and return it, then remove it from the DB. If the token doesn't exist it will return null.

$data = EmailConfirmation::check($_GET['token')); // $_POST saved for this token
