Dynamic port number for Memchaced – Azure Web App -> Redis Cahe via Memcached

Update: I have already build a PHP script to make all changes that I need at “master.php” file. Now, I need to run it every time that W3TC saves a new configuration.

https://hookr.io/plugins/w3-total-cache/0.9.3/actions/w3tc_saving_options/

// define the w3tc_saving_options callback
function action_w3tc_saving_options( $config, $this__config, $config_admin ) {
    // make action magic happen here...
}; 

// add the action
add_action( 'w3tc_saving_options', 'action_w3tc_saving_options', 10, 3 );

Thanks Nigro,

Your link are very helpful, however, I need to execute my function after W3TC save the configuration on “master.php” file.

I tried ‘w3tc_saved_options’ action, but isn’t working. W3TC is saving the “master.php” after this action (overwriting my modified file).

I had to create a new hook to enable my plugin. I hacked admin.php (\wp-content\plugins\w3-total-cache\inc\functions) and have added a “w3tc_after_save_options”. However, when I save configuration using “General Settings” page, It is not working. It appears that this page saves a new configuration after the admin.php finishing save process.

(new) admin.php:

(...)
/**
     * Update CloudFront CNAMEs
     */
    if ($update_cf_cnames) {
        $error = null;
        $w3_plugin_cdn->update_cnames($error);
    }

    /**
     * Rebuild master.php config file
     * */
//    w3tc_azure_memcached();

    do_action('w3tc_after_save_options',$new_config);

    return true;
}

/**
 * Uploads minify files to CDN
 *
 * @return void
 */
