Hallo Forengemeinde,

ich versuche gerade die Daten aus dem Checkout (am Beispiel des Paypal Gateways) als JSON zu bekommen aber sobald ich den Array in ein json_encode() packe kommt an der Ziel URL nichts an.

Hier (exemplarisch) Auszug aus dem class-wc-gateway-paypal-request.php (ab Zeile 64):

return apply_filters( 'woocommerce_paypal_args', array_merge(
			array(
				'cmd'           => '_cart',
				'business'      => $this->gateway->get_option( 'email' ),
				'no_note'       => 1,
				'currency_code' => get_woocommerce_currency(),
				'charset'       => 'utf-8',
				'rm'            => is_ssl() ? 2 : 1,
				'upload'        => 1,
				'return'        => esc_url( add_query_arg( 'utm_nooverride', '1', $this->gateway->get_return_url( $order ) ) ),
				'cancel_return' => esc_url( $order->get_cancel_order_url() ),
				'page_style'    => $this->gateway->get_option( 'page_style' ),
				'paymentaction' => $this->gateway->get_option( 'paymentaction' ),
				'bn'            => 'WooThemes_Cart',
				'invoice'       => $this->gateway->get_option( 'invoice_prefix' ) . $order->get_order_number(),
				'custom'        => json_encode( array( 'order_id' => $order->id, 'order_key' => $order->order_key ) ),
				'notify_url'    => $this->notify_url,
				'first_name'    => $order->billing_first_name,
				'last_name'     => $order->billing_last_name,
				'company'       => $order->billing_company,
				'address1'      => $order->billing_address_1,
				'address2'      => $order->billing_address_2,
				'city'          => $order->billing_city,
				'state'         => $this->get_paypal_state( $order->billing_country, $order->billing_state ),
				'zip'           => $order->billing_postcode,
				'country'       => $order->billing_country,
				'email'         => $order->billing_email
			),
			$this->get_phone_number_args( $order ),
			$this->get_shipping_args( $order ),
			$this->get_line_item_args( $order )
		), $order );

Will ich dann ersetzen durch etwa so (nur mehr Felder am Ende):

return apply_filters( 'woocommerce_paypal_args',json_encode( array( 'feld1' => $feld1, 'feld2' => $feld2 )))

Nun ja, bislang kommt da am Ende nichts an. Was ist falsch?
