#Installation

#Laravel

Require this package in your composer.json and update composer. This will download the package and the dompdf + fontlib libraries also.

composer require barryvdh/laravel-dompdf

#Lumen

After updating composer add the following lines to register provider in bootstrap/app.php

$app->register(\Barryvdh\DomPDF\ServiceProvider::class);

To change the configuration, copy the config file to your config folder and enable it in bootstrap/app.php:

$app->configure('dompdf');

#Using

You can create a new DOMPDF instance and load a HTML string, file or view name. You can save it to a file, or stream (show in browser) or download.

    use Barryvdh\DomPDF\Facade\Pdf;

    $pdf = Pdf::loadView('pdf.invoice', $data);
    return $pdf->download('invoice.pdf');

or use the App container:

    $pdf = App::make('dompdf.wrapper');
    $pdf->loadHTML('<h1>Test</h1>');
    return $pdf->stream();

Or use the facade:

You can chain the methods:

    return Pdf::loadFile(public_path().'/myfile.html')->save('/path-to/my_stored_file.pdf')->stream('download.pdf');

You can change the orientation and paper size, and hide or show errors (by default, errors are shown when debug is on)

    Pdf::loadHTML($html)->setPaper('a4', 'landscape')->setWarnings(false)->save('myfile.pdf')

If you need the output as a string, you can get the rendered PDF with the output() function, so you can save/output it yourself.

Use php artisan vendor:publish to create a config file located at config/dompdf.php which will allow you to define local configurations to change some settings (default paper etc). You can also use your ConfigProvider to set certain keys.

#Configuration

The defaults configuration settings are set in config/dompdf.php. Copy this file to your own config directory to modify the values. You can publish the config using this command:

    php artisan vendor:publish --provider="Barryvdh\DomPDF\ServiceProvider"

You can still alter the dompdf options in your code before generating the pdf using this command:

    Pdf::setOption(['dpi' => 150, 'defaultFont' => 'sans-serif']);

Available options and their defaults:

  • rootDir: "{app_directory}/vendor/dompdf/dompdf"

#PDF/A-3b Support

Requires dompdf >= 3.1.0 and the CPDF backend (default).

You can generate PDF/A-3b compliant PDFs for archival purposes. Enable it globally via config or per-PDF at runtime.

Global (config/dompdf.php):

    'pdfa' => [
        'enabled' => true,
    ],

Per-PDF at runtime:

    $pdf = Pdf::loadView('invoice', $data)
        ->setPdfA()
        ->download('invoice.pdf');

Important: PDF/A requires all fonts to be embedded. Core PDF fonts (Helvetica, Courier, Times) are not embedded and will cause validation failures. Use fonts like DejaVu Sans or DejaVu Serif instead.

#Zugferd / Factur-X (embedded XML invoices)

For PDF/A-3b with embedded XML attachments (e.g. Zugferd/Factur-X electronic invoicing), you can use addEmbeddedFile() and setAdditionalXmpRdf():

    $pdf = Pdf::loadView('invoice', $data)->setPdfA();

    // Add XMP metadata for Factur-X
    $pdf->setAdditionalXmpRdf(
        '<rdf:Description rdf:about=""
            xmlns:fx="urn:factur-x:pdfa:CrossIndustryDocument:invoice:1p0#">
            <fx:DocumentType>INVOICE</fx:DocumentType>
            <fx:DocumentFileName>factur-x.xml</fx:DocumentFileName>
            <fx:Version>1.0</fx:Version>
            <fx:ConformanceLevel>BASIC</fx:ConformanceLevel>
        </rdf:Description>'
    );

    // Embed the XML invoice
    $pdf->addEmbeddedFile(
        storage_path('invoices/factur-x.xml'),
        'factur-x.xml',
        'Factur-X Invoice',
        'text/xml'
    );

    return $pdf->download('invoice.pdf');

#Tip: UTF-8 support

In your templates, set the UTF-8 Metatag:

<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>

#Tip: Page breaks

You can use the CSS page-break-before/page-break-after properties to create a new page.

<style>
.page-break {
    page-break-after: always;
}
</style>
<h1>Page 1</h1>
<div class="page-break"></div>
<h1>Page 2</h1>
