Invoice4U Library

Include the class in your PHP project, and instance and new Invoice object. Use the various methods to define the invoice properties:

$invoice=new Invoice();
$invoice->setUsername("Test@Username");
$invoice->setType(Invoice::INVOICE);
$invoice->addProduct( array("id"=>"00000001",
                                              "desc"=>"Product 1 bla",
                                              "count"=>"5",
                                              "price"=>"1000") );
$invoice->setEmail("test@mail.com");
$invoice->setSubject("Test - Invoice");
$invoice->setCompanyInfo("Test Company");
$invoic->send();

Please note: You need an email to send invoices to clients.

Running the send() method returns a response / error code, as detailed below.
