Answer a question

I would like to get all slugs and names of all the WooCommerce order statuses. I tried the answers from the following thread: Woocommerce get list of order statuses list but with no success.

I use latest woocommerce version. Any help is appreciated.

You will use the dedicated function wc_get_order_statuses(), from WC_Order functions, which give you by default the following array:

$order_statuses = array(
    'wc-pending'    => _x( 'Pending payment', 'Order status', 'woocommerce' ),
    'wc-processing' => _x( 'Processing', 'Order status', 'woocommerce' ),
    'wc-on-hold'    => _x( 'On hold', 'Order status', 'woocommerce' ),
    'wc-completed'  => _x( 'Completed', 'Order status', 'woocommerce' ),
    'wc-cancelled'  => _x( 'Cancelled', 'Order status', 'woocommerce' ),
    'wc-refunded'   => _x( 'Refunded', 'Order status', 'woocommerce' ),
    'wc-failed'     => _x( 'Failed', 'Order status', 'woocommerce' ),
);

All custom additional order statuses will be included too as the filter hook wc_order_statuses is applied inside this function.
