How to sync a WordPress user account to an Event Espresso Contact. This is useful if you've installed the WP User Integration after registrations have already been recorded.

how-to.md

Step 1 -- Gather the user and Event Espresso Contact IDs

You can get the user ID from the WP Users page. You can get the Event Espresso Contact ID from the Event Espresso > Registrations > Contact list admin page.

In this example, the user ID is 18 and the Event Espresso Attendee ID is 862.

Step 2 -- Install the Debug Bar and Debug Bar console plugins

Available here: Debug Bar Debug Bar Console

Step 3 -- PHP code

You click on the Debug Bar link, then Console add add the following code, replacing the User ID and Meta Value.

<?php
global $wpdb;
$user_id = 18;
$meta_key = $wpdb->prefix . 'EE_Attendee_ID';
$meta_value = 862;
add_user_meta( $user_id, $meta_key, $meta_value, true );
?>

Then you click Run.

The Debug Bar Console plugin should be fine if you're using WP 4.9.4 or greater.

If anybody out there is still needing to use this code, like me, I have used it with the Code Snippets plugin rather than using Debug Console, since I already have that plugin installed for other reasons. I made a new snippet that is set to only run once. Worked like a charm. Thank you Josh for keeping this post here!
