Simple management of PDF generation in Nette app using mPDF
- Copy source codes from Github or using Composer:
$ composer require dotblue/nette-pdf@~2.0
- Register as Configurator's extension:
extensions: mpdf: DotBlue\Mpdf\DI\Extension
First you need to tell the addon where you store PDF documents' templates.
mpdf: templatesDir: %appDir%/templates/pdf
In the app, you usually have several types of PDF documents that you wish to generate. Such type is called theme. Each theme should have its own directory located in
templatesDir. You can configure theme via many directives which mPDF supports.
mpdf: themes: invoice: margin: left: 20 right: 20 top: 20 bottom: 20
Default settings are following:
encoding: utf-8 img_dpi: 120 size: A4 margin: left: 0 right: 0 top: 0 bottom: 0
Each theme has built-in support for external stylesheet. If you put
style.css file into theme's directory, it will be automatically bundled into PDF document.
Custom fonts can be configured in following way:
fonts: roboto: R: %appDir%/fonts/Roboto.ttf
Supported types are R (regular), B (bold), I (italic) and BI (bold & italic).
There is only one service:
DotBlue\Mpdf\DocumentFactory. Granted that you have
default.latte file in our
invoice theme directory, you can create new PDF document like this:
$invoiceDocument = $documentFactory->createPdf('invoice');
$invoiceDocument is instance of
DotBlue\Mpdf\Document, which provides simple API for printing or saving, and for linking images. If you would like to save the invoice somewhere on hard drive, you can call
$invoiceDocument->saveTo(__DIR__ . '/invoice.pdf');
Or you can show document to user in browser:
Theme can support more variants. Actually method
createPdf() has second optional argument, and its default value is
default.latte. By changing this, your theme can support many variants either of type or for example of localization.
As third argument you can pass array of directives right for mPDF, which will override your theme default settings.
