-Note: LiteSpeed WordPress Cache plugin needs to be v1.3+. +~~REDIRECT>https://docs.litespeedtech.com/lscache/lscwp/cache/~~
- +
-Let's take ** WPBakery Page Builder Version 5.3 ** as an example. It used WordPress nonce in frontend. So once it got cached, the nonce will fail to pass validation once expired. With ESI, it can be made to a private/​public cache separate from full page. +
- +
-This is how to do it manually: +
- +
-In <code>js_composer/​include/​helpers/​helpers_factory.php</​code>​ line 486, +
-<code php> +
-function vc_generate_nonce( $data ) { +
- return wp_create_nonce( is_array( $data ) ? ( '​vc-nonce-'​ . implode( '​|',​ $data ) ) ( '​vc-nonce-'​ . $data ) ); +
-+
-</​code>​ +
- +
-change it to  +
-<code php> +
-function vc_generate_nonce( $data, $from_esi = false ) { +
- if ( ! $from_esi && ! vc_is_frontend_editor() ​ ) { +
- if ( method_exists( '​LiteSpeed_Cache_API',​ '​esi_enabled'​ ) && LiteSpeed_Cache_API::​esi_enabled() ) { +
- if ( method_exists( '​LiteSpeed_Cache_API',​ '​v'​ ) && LiteSpeed_Cache_API::​v( '​1.3'​ ) ) { +
- $params = array( '​data'​ => $data ) ; +
- return LiteSpeed_Cache_API::​esi_url( '​js_composer',​ '​WPBakery Page Builder',​ $params, '​default',​ true ) ;// The last parameter is to remove ESI comment wrapper +
-+
-+
-+
- return wp_create_nonce( is_array( $data ) ? ( '​vc-nonce-' ​implode( '​|',​ $data ) ) : ( '​vc-nonce-' ​$data ) ); +
-+
- +
- +
-/** +
- * @param $params +
- * +
- * @return string +
- */ +
-function hook_esi( $params ) { +
- $data = $params[ '​data'​ ] ; +
- echo vc_generate_nonce( $data, true ) ; +
- exit ; +
-+
-</code> +
- +
- +
-Then, in <​code>​js_composer/js_composer.php</​code>​ line 244, +
-<code php> +
- public function init() { +
-</​code>​ +
- +
-Change it to  +
-<code php> +
- public function init() { +
- if ( method_exists( '​LiteSpeed_Cache_API',​ '​esi_enabled'​ ) && LiteSpeed_Cache_API::​esi_enabled() ) { +
- LiteSpeed_Cache_API::​hook_tpl_esi( '​js_composer',​ '​hook_esi'​ ) ; +
-+
-</​code>​ +
- +
-Now you can see WordPress nonce can be cached correctly.+
