I need to add custom args to PayPal paying link.
The PHP function looks like this:
$paypal_args = apply_filters( 'woocommerce_paypal_args', $paypal_args );
add_filter( 'woocommerce_paypal_args' , 'change_paypal_args' );
function change_paypal_args( $paypal_args ) {
global $wp;
global $woocommerce;
$order = wc_get_order( $order_id );
$paypal_args['invoice'] = 'spi432';
$paypal_args['txn_type'] = 'cart';
$paypal_args['payment_date'] = $order->order_date;
return $paypal_args;
}
I added txn_type
and invoice
as arguments to the link. But payment_date
is not shown.
What may be the problem? Also, how can I display email of the customer?
If you enabled WP_DEBUG
you would probably see that $order_id
is undefined, and therefore $order
is not an order object, so $order->order_date
is likely a fatal error. Try passing the order as the second parameter instead.
add_filter( 'woocommerce_paypal_args' , 'so_42424283_change_paypal_args', 10, 2 );
function so_42424283_change_paypal_args( $paypal_args, $order ) {
$paypal_args['invoice'] = 'spi432';
$paypal_args['txn_type'] = 'cart';
// WC 2.6+
$paypal_args['payment_date'] = $order->order_date;
// WC 2.7
//$paypal_args['payment_date'] = $order->get_date_created();
return $paypal_args;
}
