Title: Does not update `false` values Last modified: August 6, 2020 --- # Does not update `false` values * Resolved [Matthias Günter](https://wordpress.org/support/users/mguenter/) * (@mguenter) * [5 years, 10 months ago](https://wordpress.org/support/topic/does-not-update-false-values/) * Hi! * We have noticed some strange behavior with Redis Object Cache. If the cache ** is enabled** we can not update checkboxes to a `false` state in our `wp_options` database table. You can run into the issue with the following example: * ``` add_action('customize_register', function ($wp_customize) { add_option('testc_checkbox_setting_id', true); $wp_customize->add_setting('testc_checkbox_setting_id', [ 'type' => 'option', 'sanitize_callback' => function ($checked) { return isset($checked) && true == $checked ? true : false; } ]); $wp_customize->add_control('testc_checkbox_setting_id', [ 'type' => 'checkbox', 'section' => 'static_front_page', 'label' => __('Custom Checkbox'), 'description' => __('This is a custom checkbox input.'), 'settings' => 'testc_checkbox_setting_id' ]); }); ``` * This code simply registers a new checkbox in **Design > Customizer > Homepage Settings > “CUSTOM CHECKBOX”**. If you try now to deactivate the checkbox (state: not checked), the value never gets updated in the database. * If we deactivate the Redis object cache, all is working fine. * ``` Status: Connected Client: PhpRedis (v5.2.2) Drop-in: Valid Disabled: No Filesystem: Working Ping: 1 Errors: [] PhpRedis: 5.2.2 Predis: Not loaded Credis: Not loaded PHP Version: 7.4.6 Plugin Version: 2.0.8 Redis Version: 6.0.3 Multisite: No Global Prefix: "wp_" Blog Prefix: "wp_" WP_REDIS_HOST: "redis" WP_REDIS_MAXTTL: "14400" WP_REDIS_PREFIX: "wp.io_obj:" WP_CACHE_KEY_SALT: "wp.io_obj:" Global Groups: [ "blog-details", "blog-id-cache", "blog-lookup", "global-posts", "networks", "rss", "sites", "site-details", "site-lookup", "site-options", "site-transient", "users", "useremail", "userlogins", "usermeta", "user_meta", "userslugs", "blog_meta" ] Ignored Groups: [ "counts", "plugins", "themes", "mailster", "WPML_ST_Package_Factory" ] Unflushable Groups: [] Drop-ins: [ "maintenance.php v by ", "Redis Object Cache Drop-In v2.0.8 by Till Krüss" ] ``` * Regards, Matthew 🙂 Viewing 8 replies - 1 through 8 (of 8 total) * Plugin Author [Till Krüss](https://wordpress.org/support/users/tillkruess/) * (@tillkruess) * [5 years, 10 months ago](https://wordpress.org/support/topic/does-not-update-false-values/#post-13244124) * I never got an email notification for this. * This is weird, have you tried to re-product this on a clean WP installation? * Thread Starter [Matthias Günter](https://wordpress.org/support/users/mguenter/) * (@mguenter) * [5 years, 9 months ago](https://wordpress.org/support/topic/does-not-update-false-values/#post-13248584) * Hi [@tillkruess](https://wordpress.org/support/users/tillkruess/) ! * Yeah, I tried this on a clean installation. * Just give the example code above a chance and you will encounter this issue. * Regards, Matthew 🙂 * Plugin Author [Till Krüss](https://wordpress.org/support/users/tillkruess/) * (@tillkruess) * [5 years, 9 months ago](https://wordpress.org/support/topic/does-not-update-false-values/#post-13251357) * If you remove `add_option('testc_checkbox_setting_id', true);` that code snippet works fine for me on 2.0.10. Saves the state of the checkbox 👍🏻 * Thread Starter [Matthias Günter](https://wordpress.org/support/users/mguenter/) * (@mguenter) * [5 years, 9 months ago](https://wordpress.org/support/topic/does-not-update-false-values/#post-13321098) * Hi again! * Unfortunately I can not remove the `add_option` as it is neede for `autoload` functionality of `wp_options` table itself. Can you still save the state “unchecked” without `add_option` functionality? * Regards, Matthew 🙂 * Plugin Author [Till Krüss](https://wordpress.org/support/users/tillkruess/) * (@tillkruess) * [5 years, 9 months ago](https://wordpress.org/support/topic/does-not-update-false-values/#post-13323716) * In that case, it’s not working because your code is broken 👍🏻 * Thread Starter [Matthias Günter](https://wordpress.org/support/users/mguenter/) * (@mguenter) * [5 years, 9 months ago](https://wordpress.org/support/topic/does-not-update-false-values/#post-13323779) * Hi again! * How can the code be broken? `add_option` only adds the option to database when it is not already written. * Regards, Matthew 🙂 * Plugin Author [Till Krüss](https://wordpress.org/support/users/tillkruess/) * (@tillkruess) * [5 years, 9 months ago](https://wordpress.org/support/topic/does-not-update-false-values/#post-13323897) * You should not set options in your `customize_register` action. * If you want to debug why it’s not working with Redis, try using `redis-cli monitor` and see what happens when `add_option()` is called. * Thread Starter [Matthias Günter](https://wordpress.org/support/users/mguenter/) * (@mguenter) * [5 years, 9 months ago](https://wordpress.org/support/topic/does-not-update-false-values/#post-13326341) * Hi again! * I really thought I was technically good at WordPress, but you never stop learning. This really solves the problem.
