Set a member's role in Restrict Content Pro anytime their status changes

gistfile1.php

<?php

function pw_rcp_update_role_status_change( $new_status, $user_id ) {
	
	$role = false;

	switch( $new_status ) {

		case 'expired'   :
		case 'pending'   :
		case 'free'      :
		case 'cancelled' :

			$role = 'subscriber';

			break;

		case 'active'    :

			// if you want, set a role here

			break;

	}

	if( ! empty( $role ) ) {

		$user = new WP_User( $user_id );
		$user->set_role( $role );

	}

}
add_action( 'rcp_set_status', 'pw_rcp_update_role_status_change', 10, 2 );

Shouldn't that switch statement be on the var $new_status instead of $status?

Yep, good catch.
