Return Value of load_plugin_textdomain

Question

Good Day,

I'm trying to translate my plugin but it doesn't seems to work.

I read that I should check the return value of "load_plugin_textdomain" to see if it's false (meaning it doesn't find my translation file), but I cannot find how to find this value.

Can someone point me in the right direction?

Thanks

EDIT As requested here is the lines to load it

function ap_action_init() {
    load_plugin_textdomain('my_plugin', false, WP_PLUGIN_DIR . '/languages' );
}

// Localization

// Add Actions
add_action('init', 'ap_action_init');

Answer 1

global $langOK;
add_action( 'plugins_loaded', 'myplugin_load_textdomain' );
function myplugin_load_textdomain() {
    global $langOK;
    $langOK = load_plugin_textdomain( 'my-plugin', false, dirname( plugin_basename( __FILE__ ) ) . '/languages' );
}

Later you can check the value of $langOK ( TRUE = success, FALSE = failure ).
