Clear Cache Everywhere

FAQ

How does this plugin clear cache?

It flushes WordPress object cache, transients, sessions, rewrite rules, and any configured third-party caches. If a hosting cache purge URL is set, it will be called as well. Additionally, it forces browsers to reload fresh content.

Does this work with all hosting providers?

This depends on your hosting provider. If they offer a cache purge URL, you can configure it in the plugin settings. For example, if you have GoDaddy’s Website Security and Backups, you can navigate to Firewall > Settings > Performance > Clear Cache, then grab the Clear Cache API link.

Will this force browsers to load fresh content?

Yes! The plugin sends cache-control headers to prompt browsers to reload updated content.

Can I add custom cache clearing actions?

Yes! Developers can hook into cceverywhere_after_clear_cache and cceverywhere_custom_settings:

<?php
// Action to purge a custom cache directory after clearing cache
add_action( 'cceverywhere_after_clear_cache', function() {
    // Check if the custom cache purge option is enabled
    $prefix = 'clear_cache_everywhere_';
    if ( get_option( $prefix . 'purge_custom_cache_directory', false ) ) {
        // Purge a custom cache directory
        $cache_dir = WP_CONTENT_DIR . '/cache/myplugin/';
        if ( file_exists( $cache_dir ) ) {
            array_map( 'unlink', glob( $cache_dir . '*' ) );
        }
    }
} );

// Filter to add custom settings field for the action above
add_filter( 'cceverywhere_custom_settings', function( $fields ) {
    // Define a custom checkbox field
    $fields[] = [
        'key'       => 'purge_custom_cache_directory',
        'title'     => __( 'Purge Custom Cache Directory', 'clear-cache-everywhere' ),
        'type'      => 'checkbox',
        'sanitize'  => 'sanitize_checkbox',
        'section'   => 'custom',
        'default'   => FALSE,
        'comments'  => __( 'Enable this option to automatically purge a custom cache directory (e.g., for your plugin\'s cache). The cache will be cleared after the global cache is cleared.', 'clear-cache-everywhere' ),
    ];
    return $fields;
} );
?>

Is there a function to trigger clearing cache everywhere?

Yes! A helper function is available for you to use: cceverywhere_clear_all( $log_results = false ).

The function returns the results of the cache clearing processing. Optionally, you can log the results by setting the $log_results parameter to true. This will log the results to the debug log.
