I’m trying to add a simple radio button to the signup form, and I’ve got as far as adding that to the signup form. On bp_core_activate_account the data goes into the meta of the wp_signups table. Then on activation that data is transferred into the wp_usermeta table – except the value of notification_newsletter.

In the newslettersignup_bp_activate function I realise in the example below that I’m trying to pass in the POST data (which has long gone), but the data that is passed into that function only contains the user_id. Other examples of this process suggest that this is an array with all the registration meta in it – print_r returns nothing more than user_id.

Why aren’t all the values in wp_signups -> meta transfered to wp_usermeta in the activation process? And what can I put into update_user_meta to get that value?

My mind boggles, help gratefully accepted. Code snippet below: 

/**
* Add custom userdata from register.php
*/
function newslettersignup_bp_signup_field( $usermeta ) {
	$usermeta['notification_newsletter'] = $_POST['notification_newsletter'];

	return $usermeta;
}
add_filter( 'bp_signup_usermeta', 'newslettersignup_bp_signup_field' );

/**
* Update usermeta with custom registration data
*/
function newslettersignup_bp_activate( $user ) {

//print_r($user);

	update_user_meta( $user, 'notification_newsletter', $_POST['notification_newsletter'] );	

	return $user;
}
add_filter( 'bp_core_activate_account', 'newslettersignup_bp_activate' );
