Access Woocommerce Session data

Question

I'm trying to access a value in the Woocommerce Session Object , without any result.

Having this session in WC:

WC_Session_Handler Object
(
    [_cookie:protected] => wp_woocommerce_session_b520c2589cabce0f648a4494ecfed80e

            [chosen_shipping_methods] => 
        )

    [_dirty:protected] => 1
)

I need to get this value:

is_vat_exempt

Consulting the documentation I've found the function:

get( $key, $default = null ) 

What I'm doing wrong? I will appreciate any help.

Thank you

Answer 1

There is 2 ways:

1) From your WC_Session_Handler Object, you will use get_session_data() method on it:

$session = new WC_Session_Handler();

$session_data = $session->get_session_data();

$customer = maybe_unserialize( $session_data['customer'] );

$is_vat_exempt = $customer['$is_vat_exempt'];

if( $is_vat_exempt ) {
    // Do something
} else {
    // Do something else
}

2) Or you can use directly the WC_Session live object with the get() method this way:

$customer = WC()->session->get('customer');

$is_vat_exempt = $customer['$is_vat_exempt'];

if( $is_vat_exempt ) {
    // Do something
} else {
    // Do something else
}

Both ways works…

Answer 2

I think you are looking for this...

// Set the customer ID to the current session
$customer = new WC_Customer( 0, true );

// Use the class method to determine vat status
$vat_exempt = $customer->is_vat_exempt();
