Title: FYI: Flush button script breaks update Last modified: July 14, 2020 --- # FYI: Flush button script breaks update * Resolved [Jagster_](https://wordpress.org/support/users/jagster_/) * (@jagster_) * [5 years, 11 months ago](https://wordpress.org/support/topic/fyi-flush-button-script-breaks-update/) * I know this is not your issue, but it is UX-way 😉 * Quite widely used script that shows flush-button at admin-bar will break updates beginning v2. * Have you considered to do something similar? Every now and then must flush the cache and route cia settings isn’t… stylish * And I ment this one: * ``` # Check: https://onexa.nl/wordpress/toolbar-link-redis-object-cache/ /** * Add a link to the Admin Toolbar to easily flush the Redis cache (Redis Object Cache plugin) * * @author Hiranthi Herlaar, onexa.nl * * @var $wp_admin_bar > https://codex.wordpress.org/Class_Reference/WP_Admin_Bar **/ function redis_add_toolbar_link( $wp_admin_bar ) { if ( current_user_can( 'manage_options' ) && is_plugin_active( 'redis-cache/redis-cache.php' ) ) { $RedisObjectCache = new RedisObjectCache; if ( $RedisObjectCache->get_redis_status() ) { $RedisPage = is_multisite() ? 'settings.php?page=redis-cache' : 'options-general.php?page=redis-cache'; // Flush Redis Cache trough WP Rocket Admin Bar Menu $args = array( 'id' => 'flush-redis-cache', 'title' => __( 'Flush Redis Cache' ) . '', 'parent' => false, 'href' => wp_nonce_url( network_admin_url( add_query_arg( 'action', 'flush-cache', $RedisPage ) ), 'flush-cache' ) ); $wp_admin_bar->add_node( $args ); } // end REDIS } } // end add_toolbar_link add_action( 'admin_bar_menu', 'redis_add_toolbar_link', 999 ); ``` - This topic was modified 5 years, 11 months ago by [Jagster_](https://wordpress.org/support/users/jagster_/). - This topic was modified 5 years, 11 months ago by [Jagster_](https://wordpress.org/support/users/jagster_/). - This topic was modified 5 years, 11 months ago by [Jan Dembowski](https://wordpress.org/support/users/jdembowski/).

Change the line `$RedisObjectCache = new RedisObjectCache;` … to … `$RedisObjectCache = Rhubarb\RedisCache::instance();` * And `'href' => wp_nonce_url( network_admin_url( add_query_arg( 'action', 'flush- cache', $RedisPage ) ), 'flush-cache' )` … to … `'href' => $RedisObjectCache- >action_link( 'flush-cache' )` * Sadly I am unable to test it a but there is a good chance that this might just work. * Plugin Author [Till Krüss](https://wordpress.org/support/users/tillkruess/) * (@tillkruess) * [5 years, 11 months ago](https://wordpress.org/support/topic/fyi-flush-button-script-breaks-update/#post-13122118) * Hi [@jagster_](https://wordpress.org/support/users/jagster_/), * is this causing your site to crash, or is the button just not working. * Feel free to submit a pull request: [https://github.com/rhubarbgroup/redis-cache/issues/224](https://github.com/rhubarbgroup/redis-cache/issues/224) * Plugin Author [Till Krüss](https://wordpress.org/support/users/tillkruess/) * (@tillkruess) * [5 years, 11 months ago](https://wordpress.org/support/topic/fyi-flush-button-script-breaks-update/#post-13122264) * [@jagster_](https://wordpress.org/support/users/jagster_/): * Could you try adding this snippet above your `redis_add_toolbar_link()` function and see if it works again? * ``` if ( ! isset( $GLOBALS[ 'redisObjectCache' ] ) ) { $GLOBALS[ 'redisObjectCache' ] = Rhubarb\RedisCache\Plugin::instance(); } if ( ! class_exists( 'RedisObjectCache' ) ) : class RedisObjectCache { public function get_redis_status() { return Rhubarb\RedisCache\Plugin::instance()->get_redis_status(); } } endif; ``` * Thread Starter [Jagster_](https://wordpress.org/support/users/jagster_/) * (@jagster_) * [5 years, 11 months ago](https://wordpress.org/support/topic/fyi-flush-button-script-breaks-update/#post-13122559) * I had this script in use in 14 slightly different WordPress installs and all of them crashed. * Sure, I’ll give a try. * Thread Starter [Jagster_](https://wordpress.org/support/users/jagster_/) * (@jagster_) * [5 years, 11 months ago](https://wordpress.org/support/topic/fyi-flush-button-script-breaks-update/#post-13122590) * It worked. Well, I don’t know what will happend with that if trying do update from 1.6.x because all of my sites use already 2.0.2. * BTW, metrics works just fine. Did you fix that or am I just lucky 😉 - This reply was modified 5 years, 11 months ago by [Jagster_](https://wordpress.org/support/users/jagster_/). * Plugin Author [Till Krüss](https://wordpress.org/support/users/tillkruess/) * (@tillkruess) * [5 years, 11 months ago](https://wordpress.org/support/topic/fyi-flush-button-script-breaks-update/#post-13122782) * The metrics worked, just some weird corner cases failed. That’s fixed in v2.0.3, which was just released. * I’ll include an Adminbar node with the next version, you can use the snippet above until then to fix your existing code. * Feel free to chime in here: [https://github.com/rhubarbgroup/redis-cache/issues/224](https://github.com/rhubarbgroup/redis-cache/issues/224) * Thread Starter [Jagster_](https://wordpress.org/support/users/jagster_/) * (@jagster_) * [5 years, 11 months ago](https://wordpress.org/support/topic/fyi-flush-button-script-breaks-update/#post-13122800) * Thanks! * I’m really bad at git and Github.
