Freshbooks API show details - php

Question

I am using the php library from here and I have a small problem.
To get some info for a invoice 118868, I can do this
<?php
$invoice_id=118868;
$invoice=$freshbooks->invoiceGet($invoice_id);
print_r($invoice);
?>
This is the output for print_r
Class Object ( [#attributes] => stdClass Object ( [status] => ok ) [invoice] => stdClass Object ( [invoice_id] => 00000219023 [estimate_id] => stdClass Object ( ) [number] => 8822 [client_id] => 83 [contacts] => stdClass Object ( [contact] => stdClass Object ( [contact_id] => 0 ) ) [recurring_id] => stdClass Object ( ) [organization] => Jimmy Thwart [first_name] => stdClass Object ( ) [last_name] => stdClass Object ( ) [p_street1] => stdClass Object ( ) [p_street2] => stdClass Object ( ) [p_city] => stdClass Object ( ) [p_state] => stdClass Object ( ) [p_country] => stdClass Object ( ) [p_code] => stdClass Object ( ) [po_number] => 10002 [status] => sent [amount] => 16.90 [amount_outstanding] => 16.90 [paid] => 0.00 [date] => 2013-01-31 00:00:00 [notes] => stdClass Object ( ) [terms] => Your slot can only be secured upon payment.

I hope the output can only be the URL and not this whole chunk of code.
Output wanted:
https://example.freshbooks.com/view/vgPb2TNGCR7n8JV
However, it lists all information of the invoice. How do I get only the invoice URL?

Answer 1

Well, using the output of your code, you can see what the elements of $invoice are. Use the one that you need.

Answer 2

Invoice is an instane of a class. You should treat it like all instances.
To get URL value you can do the next:
<?php
$invoice_id=118868;
$invoice=$freshbooks->invoiceGet($invoice_id);
print $invoice->url;
?>
or there's another possible value you're looking for:
<?php
$invoice_id=118868;
$invoice=$freshbooks->invoiceGet($invoice_id);
print $invoice->links->client_view;
?>
According to official API doc <url> is not supporting any more, so you should use <links> "element to provide your customers with direct links to the invoice for editing, viewing by the client and viewing by an administrator."
