Overview

With horstoeko/zugferd you can read and write xml files containing electronic invoice data in the Minimum-, Basic-, EN16931-, Extended- and XRechnung Profile. In addition, it is possible to attach the XML data to an existing PDF file, which was created from an ERP system, for example. If both an XML file (or XML string) and a PDF file (or a PDF in the form of a string) exist, then a compliant PDF file with attachment can be created using the ZugferdDocumentPdfMerger class.

The advantage of this library is that you don't have to worry about whether a particular XML element exists in a desired profile - you can use the same program code for all supported profiles.

Supported profiles

  • EN16931 Minimum
  • EN16931 Basic
  • EN16931 Basic WL
  • EN16931 Comfort
  • EN16931 Extended
  • EN16931 XRechnung 1.x
  • EN16931 XRechnung 2.x
  • EN16931 XRechnung 3.x

Note: This package provides only support for CII - not UBL

Reading a xml file

The central entry point to read XML data is the class ZugferdDocumentReader. Among other things, this provides methods for reading header and line information, as can be seen in the following example:

use horstoeko\zugferd\ZugferdDocumentReader;

$document = ZugferdDocumentReader::readAndGuessFromFile(dirname(__FILE__) . "/xml/factur-x.xml");

$document->getDocumentInformation($documentno, $documenttypecode, $documentdate, $invoiceCurrency, $taxCurrency, $documentname, $documentlanguage, $effectiveSpecifiedPeriod);

echo "\r\nGeneral document information\r\n";
echo "----------------------------------------------------------------------\r\n";
echo "Profile:               {$document->getProfileDefinitionParameter("name")}\r\n";
echo "Profile:               {$document->getProfileDefinitionParameter("altname")}\r\n";
echo "Document No:           {$documentno}\r\n";
echo "Document Type:         {$documenttypecode}\r\n";
echo "Document Date:         {$documentdate->format("Y-m-d")}\r\n";
echo "Invoice currency:      {$invoiceCurrency}\r\n";
echo "Tax currency:          {$taxCurrency}\r\n";

if ($document->firstDocumentPosition()) {
    echo "\r\nDocument positions\r\n";
    echo "----------------------------------------------------------------------\r\n";
    do {
        $document->getDocumentPositionGenerals($lineid, $linestatuscode, $linestatusreasoncode);
        $document->getDocumentPositionProductDetails($prodname, $proddesc, $prodsellerid, $prodbuyerid, $prodglobalidtype, $prodglobalid);
        $document->getDocumentPositionGrossPrice($grosspriceamount, $grosspricebasisquantity, $grosspricebasisquantityunitcode);
        $document->getDocumentPositionNetPrice($netpriceamount, $netpricebasisquantity, $netpricebasisquantityunitcode);
        $document->getDocumentPositionLineSummation($lineTotalAmount, $totalAllowanceChargeAmount);
        $document->getDocumentPositionQuantity($billedquantity, $billedquantityunitcode, $chargeFreeQuantity, $chargeFreeQuantityunitcode, $packageQuantity, $packageQuantityunitcode);

        }

        }

Reading a pdf file with xml attachment

Reading invoice data from a PDF is similar: you just need to use the ZugferdDocumentPdfReader class instead of ZugferdDocumentReader:

  use horstoeko\zugferd\ZugferdDocumentPdfReader;

  $document = ZugferdDocumentPdfReader::readAndGuessFromFile(dirname(__FILE__) . "/xml/factur-x.pdf");

The further reading of the invoice data is then identical with Reading a xml file

Writing a xml file

The ZugferdDocumentBuilder class is again the central entry point to generate compliant XML data:

  use horstoeko\zugferd\ZugferdDocumentBuilder;
  use horstoeko\zugferd\ZugferdProfiles;

  // Create an empty invoice document in the EN16931 profile
  $document = ZugferdDocumentBuilder::CreateNew(ZugferdProfiles::PROFILE_EN16931);

  // Add invoice and position information
  $document
    ->setDocumentInformation("471102", "380", \DateTime::createFromFormat("Ymd", "20180305"), "EUR")
    ->addDocumentNote('Rechnung gemäß Bestellung vom 01.03.2018.')
    ->setDocumentSupplyChainEvent(\DateTime::createFromFormat('Ymd', '20180305'))
    ->setDocumentSeller("Lieferant GmbH", "549910")
    ->addDocumentSellerGlobalId("4000001123452", "0088")
    ->addDocumentSellerTaxRegistration("FC", "201/113/40209")
    ->addDocumentSellerTaxRegistration("VA", "DE123456789")
    ->setDocumentSellerAddress("Lieferantenstraße 20", "", "", "80333", "München", "DE")
    ->setDocumentBuyer("Kunden AG Mitte", "GE2020211")
    ->setDocumentBuyerAddress("Kundenstraße 15", "", "", "69876", "Frankfurt", "DE")
    ->addDocumentTax("S", "VAT", 275.0, 19.25, 7.0)
    ->addDocumentTax("S", "VAT", 198.0, 37.02, 19.0)
    ->setDocumentSummation(529.87, 529.87, 473.00, 0.0, 0.0, 473.00, 56.27, null, 0.0)
    ->addDocumentPaymentTerm("Zahlbar innerhalb 30 Tagen netto bis 04.04.2018, 3% Skonto innerhalb 10 Tagen bis 15.03.2018")
    ->addNewPosition("1")
    ->setDocumentPositionProductDetails("Trennblätter A4", "", "TB100A4", null, "0160", "4012345001235")
    ->setDocumentPositionGrossPrice(9.9000)
    ->setDocumentPositionNetPrice(9.9000)
    ->setDocumentPositionQuantity(20, "H87")
    ->addDocumentPositionTax('S', 'VAT', 19)
    ->setDocumentPositionLineSummation(198.0)
    ->addNewPosition("2")
    ->setDocumentPositionProductDetails("Joghurt Banane", "", "ARNR2", null, "0160", "4000050986428")
    ->SetDocumentPositionGrossPrice(5.5000)
    ->SetDocumentPositionNetPrice(5.5000)
    ->SetDocumentPositionQuantity(50, "H87")
    ->AddDocumentPositionTax('S', 'VAT', 7)
    ->SetDocumentPositionLineSummation(275.0)
    ->writeFile("/tmp/factur-x.xml");

Writing a pdf file with attached xml file

Use the class ZugferdDocumentPdfBuilder if you already have an existing print output of the invoice (for example from an ERP system) and want to add an XML data stream to the existing PDF:

  use horstoeko\zugferd\ZugferdDocumentBuilder;
  use horstoeko\zugferd\ZugferdDocumentPdfBuilder;
  use horstoeko\zugferd\ZugferdProfiles;

  // Create an empty invoice document in the EN16931 profile
  $document = ZugferdDocumentBuilder::CreateNew(ZugferdProfiles::PROFILE_EN16931);

  // Add invoice and position information
  $document
    ->setDocumentInformation("471102", "380", \DateTime::createFromFormat("Ymd", "20180305"), "EUR")
    ->addDocumentNote('Rechnung gemäß Bestellung vom 01.03.2018.')
    ->setDocumentSupplyChainEvent(\DateTime::createFromFormat('Ymd', '20180305'))
    ->setDocumentSeller("Lieferant GmbH", "549910")
    ->addDocumentSellerGlobalId("4000001123452", "0088")
    ->addDocumentSellerTaxRegistration("FC", "201/113/40209")
    ->addDocumentSellerTaxRegistration("VA", "DE123456789")
    ->setDocumentSellerAddress("Lieferantenstraße 20", "", "", "80333", "München", "DE")
    ->setDocumentBuyer("Kunden AG Mitte", "GE2020211")
    ->setDocumentBuyerAddress("Kundenstraße 15", "", "", "69876", "Frankfurt", "DE")
    ->addDocumentTax("S", "VAT", 275.0, 19.25, 7.0)
    ->addDocumentTax("S", "VAT", 198.0, 37.02, 19.0)
    ->setDocumentSummation(529.87, 529.87, 473.00, 0.0, 0.0, 473.00, 56.27, null, 0.0)
    ->addDocumentPaymentTerm("Zahlbar innerhalb 30 Tagen netto bis 04.04.2018, 3% Skonto innerhalb 10 Tagen bis 15.03.2018")
    ->addNewPosition("1")
    ->setDocumentPositionProductDetails("Trennblätter A4", "", "TB100A4", null, "0160", "4012345001235")
    ->setDocumentPositionGrossPrice(9.9000)
    ->setDocumentPositionNetPrice(9.9000)
    ->setDocumentPositionQuantity(20, "H87")
    ->addDocumentPositionTax('S', 'VAT', 19)
    ->setDocumentPositionLineSummation(198.0)
    ->addNewPosition("2")
    ->setDocumentPositionProductDetails("Joghurt Banane", "", "ARNR2", null, "0160", "4000050986428")
    ->SetDocumentPositionGrossPrice(5.5000)
    ->SetDocumentPositionNetPrice(5.5000)
    ->SetDocumentPositionQuantity(50, "H87")
    ->AddDocumentPositionTax('S', 'VAT', 7)
    ->SetDocumentPositionLineSummation(275.0);

  // Save merged PDF (existing original and XML) to a file
  $pdfBuilder = new ZugferdDocumentPdfBuilder($document, "/tmp/existingprintlayout.pdf");
  $pdfBuilder->generateDocument()->saveDocument("/tmp/merged.pdf");

  // Alternatively, you can also return the merged output (existing original and XML) as a binary string
  $pdfBuilder = new ZugferdDocumentPdfBuilder($document, "/tmp/existingprintlayout.pdf");
  $pdfBinaryString = $pdfBuilder->generateDocument()->downloadString("merged.pdf");

Merge existing PDF and XML

Let's assume we already have a compliant XML (for example in the Comfort profile) and a PDF that already contains the print layout. Then it is possible to merge these two files into a compliant PDF (with XML attachment) using the class ZugferdDocumentPdfMerger.

use horstoeko\zugferd\ZugferdDocumentPdfMerger;

require dirname(__FILE__) . "/../vendor/autoload.php";

$existingXml = dirname(__FILE__) . "/invoice_1.xml";
$existingPdf = dirname(__FILE__) . "/emptypdf.pdf";
$mergeToPdf = dirname(__FILE__) . "/fullpdf.pdf";

if (!file_exists($existingXml) || !file_exists($existingPdf)) {
    throw new \Exception("XML and/or PDF does not exist");
}

(new ZugferdDocumentPdfMerger($existingXml, $existingPdf))->generateDocument()->saveDocument($mergeToPdf);

XML and/or PDF do not have to be available as a file. Strings containing the corresponding data can also be passed to the ZugferdDocumentPdfMerger class.

use horstoeko\zugferd\ZugferdDocumentPdfMerger;

require dirname(__FILE__) . "/../vendor/autoload.php";

$existingXml = "<xml>,,,,,</xml>";
$existingPdf = "%PDF-1.5...........";
$mergeToPdf = dirname(__FILE__) . "/fullpdf.pdf";

(new ZugferdDocumentPdfMerger($existingXml, $existingPdf))->generateDocument()->saveDocument($mergeToPdf);
