Translate custom order status through a filter?

Question

I'm using this plugin to customize order statuses in Woocommerce: Woocommerce Order Status Manager

In documentation it says I translate order status name using the following filter:

wc_order_status_manager_order_status_name

Indeed, in plugin source there are these lines:

public function get_name() {

    /**
     * Filter the name
     *
     * @since 1.3.0
     * @param string $name The order status name
     * @param string $slug The order status slug
     */
    return apply_filters( 'wc_order_status_manager_order_status_name', $this->name, $this->slug );
}

In my theme's functions.php I added the following code:

function af_change_shipped_status_name($name, $slug){
if ('shipped' == $slug){
    $name = __('Shipped', 'mythemetextdomain');
}   
return $name;
}

add_filter( 'wc_order_status_manager_order_status_name', 'af_change_shipped_status_name', 10, 2 );

But it's not working.

Were am I wrong?

Answer 1

Recheck your filter code closely. You are modifying $name but returning $status_name which is undefined. If you had debugging enabled, you should have seen the debug message telling you that $status_name is an undefined variable

Simply change

return $status_name;

to

return $name;
