Generate PDFs in Laravel with Mpdf.

Languages: PHP

Laravel Mpdf: Generate PDF Files with ease.

Easily generate PDF files using Laravel's Blade templates and the MPDF library. This package has been tested since Laravel 5.4.

Installation

Run this composer command in your laravel application:

composer require carlos-meneses/laravel-mpdf

Important Notes:


To start using Laravel, add the Service Provider and the Facade to your config/app.php:

Note: This package supports auto-discovery features of Laravel 5.5+, You only need to manually add the service provider and alias if working on Laravel version lower then 5.5.

'providers' => [
    // ...
    Mccarlosen\LaravelMpdf\LaravelMpdfServiceProvider::class
]
'aliases' => [
    // ...
    'PDF' => Mccarlosen\LaravelMpdf\Facades\LaravelMpdf::class
]

Basic Usage

To use Laravel Mpdf add something like this to one of your controllers. You can pass data to a view in /resources/views.

//....

use PDF;

class ReportController extends Controller 
{
    public function viewPdf()
    {
        $data = [
            'foo' => 'bar'
        ];

        $pdf = PDF::loadView('pdf.document', $data);

        return $pdf->stream('document.pdf');
    }

}

Config

You can use a custom file to overwrite the default configuration. Just execute php artisan vendor:publish --tag=mpdf-config or create config/pdf.php and add this:

return [
    'mode'                       => '',
    'format'                     => 'A4',
    'default_font_size'          => '12',
    'default_font'               => 'sans-serif',
    'margin_left'                => 10,
    'margin_right'               => 10,
    'margin_top'                 => 10,
    'margin_bottom'              => 10,
    'margin_header'              => 0,
    'margin_footer'              => 0,
    'orientation'                => 'P',
    'title'                      => 'Laravel mPDF',
    'author'                     => '',
    'watermark'                  => '',
    'show_watermark'             => false,
    'show_watermark_image'       => false,
    'watermark_font'             => 'sans-serif',
    'display_mode'               => 'fullpage',
    'watermark_text_alpha'       => 0.1,
    'watermark_image_path'       => '',
    'watermark_image_alpha'      => 0.2,
    'watermark_image_size'       => 'D',
    'watermark_image_position'   => 'P',
    'custom_font_dir'            => '',
    'custom_font_data'           => [],
    'auto_language_detection'    => false,
    'temp_dir'                   => storage_path('app'),
    'pdfa'                       => false,
    'pdfaauto'                   => false,
    'use_active_forms'           => false,
];

To override this configuration on a per-file basis use the fourth parameter of the initializing call like this:

// ...

PDF::loadView('pdf', $data, [], [
    'title' => 'Another Title',
    'margin_top' => 0
])->save($pdfFilePath);

Get instance your Mpdf

You can access all mpdf methods through the mpdf instance with getMpdf method.

use PDF;

$pdf = PDF::loadView('pdf.document', $data);
$pdf->getMpdf()->AddPage(/*...*/);

Headers and Footers

If you want to have headers and footers that appear on every page, add them to your <body> tag like this:

<htmlpageheader name="page-header">
    Your Header Content
</htmlpageheader>

<htmlpagefooter name="page-footer">
    Your Footer Content
</htmlpagefooter>

Now you just need to define them with the name attribute in your CSS:

@page {
  header: page-header;
  footer: page-footer;
}

Inside of headers and footers {PAGENO} can be used to display the page number.

Included Fonts

By default you can use all the fonts shipped with Mpdf.

Custom Fonts

You can use your own fonts in the generated PDFs. The TTF files have to be located in one folder, e.g. resources/fonts/. Add this to your configuration file (/config/pdf.php):

return [
    'custom_font_dir'  => base_path('resources/fonts/'), // don't forget the trailing slash!
    'custom_font_data' => [
        'examplefont' => [ // must be lowercase and snake_case
            'R'  => 'ExampleFont-Regular.ttf',    // regular font
            'B'  => 'ExampleFont-Bold.ttf',       // optional: bold font
            'I'  => 'ExampleFont-Italic.ttf',     // optional: italic font
            'BI' => 'ExampleFont-Bold-Italic.ttf' // optional: bold-italic font
        ]
      // ...add as many as you want.
    ]
];

Now you can use the font in CSS:

body {
  font-family: 'examplefont', sans-serif;
}

Chunk HTML

For big HTML you might get Uncaught Mpdf\MpdfException: The HTML code size is larger than pcre.backtrack_limit xxx error, or you might just get empty or blank result. In these situations you can use chunk methods while you added a separator to your HTML:

//....
use PDF;
class ReportController extends Controller 
{
    public function generate_pdf()
    {
        $data = [
            'foo' => 'hello 1',
            'bar' => 'hello 2'
        ];
        $pdf = PDF::chunkLoadView('<html-separator/>', 'pdf.document', $data);
        return $pdf->stream('document.pdf');
    }
}
<div>
    <h1>Hello World</h1>

    <table>
        <tr><td>{{ $foo }}</td></tr>
    </table>
    
    <html-separator/>

    <table>
        <tr><td>{{ $bar }}</td></tr>
    </table>

    <html-separator/>
</div>

Added Support for the Macroable Trait

You can configure the macro in the AppServiceProvider provider file.

//...
use Mccarlosen\LaravelMpdf\LaravelMpdf;

class AppServiceProvider extends ServiceProvider
{
  //...

    public function boot()
    {
        LaravelMpdf::macro('hello', function () {
            return "Hello, World!";
        });
    }

  //...
}

Now

PDF::loadView(/* ... */)->hello();
