From 6d2c70aa0da161b5f4a4a9c198bc13c0a1f1fa65 Mon Sep 17 00:00:00 2001 From: Dominik Schilling Date: Mon, 6 Apr 2015 15:10:27 +0000 Subject: [PATCH] Customizer: Refresh nonces when a session expires and the user logs in again. This was broken since 4.0 and the introduction of user session tokens. The nonces are now tied to session tokens as opposed to user IDs, and thus they change with each re-login. Custom nonces can be added through the `customize_refresh_nonces` filter. On a successful refresh request the JavaScript API will trigger a `nonce-refresh` event. See widget's update nonce as an example. props westonruter for initial patch. fixes #31294.
