Can you paste the code you’re using?

The function below is inside a class and is called by the class constructor. I get a valid return code but the page cache isn’t empty as far as I can tell.
function tw_flush_cache(){
if ($_POST['tw_flush_cache']=='1'){
if (function_exists('w3tc_pgcache_flush')) {
w3tc_pgcache_flush();
return 'w3';
} else if (function_exists('wp_cache_clear_cache')) {
wp_cache_clear_cache();
return 'sc';
}
}
return false;
}
When/where is that called? It’s important to make W3TC is initialized.

The following is a rudimentary representation of where the function lives:
(..in the main php file of a WordPress plugin…)
class WpPluginClass{
function WpPluginClass(){
$this->tw_flush_cache();
}
function tw_flush_cache(){
if ($_POST['tw_flush_cache']=='1'){
if (function_exists('w3tc_pgcache_flush')) {
w3tc_pgcache_flush();
return 'w3';
} else if (function_exists('wp_cache_clear_cache')) {
wp_cache_clear_cache();
return 'sc';
}
}
return false;
}
}
$nInst = new WpPluginClass();
The cache should be cleared when the configuration page of the plugin is saved and thus $_POST[‘tw_flush_cache’] is 1. The function returns ‘w3’ but the cache does not seem to be cleared.
So, how do I check W3TC’s initialization status?
I take it that logic working for WP Super Cache?
