XeroPHP

A client implementation of the Xero API, with a cleaner OAuth interface and ORM-like abstraction.

Background

I hate reinventing the wheel, but this was written out of desperation. I wasn't comfortable putting the implementation that's recommended by Xero in to production, even after persisting with extending it.

This is loosely based on the functional flow of XeroAPI/XeroOAuth-PHP, but is split logically into more of an OO design.

Main changes

• Variables are named clearly and only defined if actually used
• Methods are only defined in one place
• Project is split into useful components rather than one massive class
• Organised methods so it's more clear what's going on and how to debug
• More robust implementation of signing methods
• Removal of countless semantic issues

This library has been tested with Private, Public and Partner apps but is still a WIP, I'd love contributions/fixes from anyone that is keen to join the cause!

Model Generation

Any files in the XeroPHP/Models directory are system generated. Ideally, these shouldn't be modified directly, as it will be difficult to track/update. Instead, if you notice something wrong with them, have a look at the generate/ folder. This contains the generation code, which actually just scrapes http://developer.xero.com/documentation/ and parses out model/property/relation information.

Requirements

• PHP 5.5+
• php_curl extension - ensure a recent version (7.30+)
• php_openssl extension

Setup

Using composer:

  "require": {
    "calcinai/xero-php": "1.4.*"
  }

Otherwise just download the package and add it to your autoloader. Namespaces are PSR-4 compliant.

Usage

Create a XeroPHP instance (sample config included):

$xero = new \XeroPHP\Application\PrivateApplication($config);

Load a collection of objects and loop through them

$contacts = $xero->load('Accounting\\Contact')->execute();
foreach ($contacts as $contact) {
    print_r($contact);
}

Load collection of objects, for a single page, and loop through them (Why?)

$contacts = $xero->load('Accounting\\Contact')->page(1)->execute();
foreach ($contacts as $contact) {
    print_r($contact);
}

Search for objects meeting certain criteria

$xero->load('Accounting\\Invoice')
    ->where('Status', \XeroPHP\Models\Accounting\Invoice::INVOICE_STATUS_AUTHORISED)
    ->where('Type', \XeroPHP\Models\Accounting\Invoice::INVOICE_TYPE_ACCREC)
    ->execute();

or

$xero->load('Accounting\\Invoice')->where('
    Status=="' . \XeroPHP\Models\Accounting\Invoice::INVOICE_STATUS_AUTHORISED . '" AND
    Type=="' . \XeroPHP\Models\Accounting\Invoice::INVOICE_TYPE_ACCREC . '"
')->execute();

Load something by its GUID

$contact = $xero->loadByGUID('Accounting\\Contact', [GUID]);

Or create & populate it

$contact = new \XeroPHP\Models\Accounting\Contact($xero);
$contact->setName('Test Contact')
    ->setFirstName('Test')
    ->setLastName('Contact')
    ->setEmailAddress('[email protected]');

Save it

$contact->save();

If you have created a number of objects of the same type, you can save them all in a batch by passing an array to $xero->saveAll().

From v1.2.0+, Xero context can be injected directly when creating the objects themselves, which then exposes the ->save() method. This is necessary for the objects to maintain state with their relations.

Nested objects

$invoice = $xero->loadByGUID('Accounting\\Invoice', '[GUID]');
$invoice->setContact($contact);

Attachments

$attachments = $invoice->getAttachments();
foreach ($attachment as $attachment) {
    //Do something with them
    file_put_contents($attachment->getFileName(), $attachment->getContent());
}

//You can also upload attachemnts
$attachment = \XeroPHP\Models\Accounting\Attachment::createFromLocalFile('/path/to/image.jpg');
$invoice->addAttachment($attachment);

To set the IncludeOnline flag on the attachment, pass true as the second parameter for ->addAttachment().

PDF - Models that support PDF export will inherit a ->getPDF() method, which returns the raw content of the PDF. Currently this is limited to Invoices and CreditNotes.

Refer to the examples for more complex usage and nested/related objects.
