PDF Generator with Dompdf

This project is a simple PHP application that generates a PDF file based on user input using the Dompdf library. The PDF output includes dynamic content populated from a form submission, such as the user's name and quantity input.

Features

• Dynamic PDF generation: User input is passed from an HTML form, and the values are injected into a template for PDF generation.
• Security enhancements: User input is sanitized using htmlspecialchars to prevent injection attacks.
• Landscape paper orientation: The generated PDF is in A4 size and landscape orientation.
• Template-based rendering: An external HTML template (template.html) is used for flexible content generation.

Example Form

Generated PDF

CSS:

• Water.css
• Gutenberg CSS

Requirements

• PHP 7.4 or higher

• Composer for managing dependencies

• Acknowledgements

Example Code

<?php 

// This is magic constant
require __DIR__ . "/vendor/autoload.php";

use Dompdf\Dompdf;
use Dompdf\Options;

$name = htmlspecialchars($_POST["name"]);
$quantity = htmlspecialchars($_POST["quantity"]);

$options = new Options;
$options->setChroot(__DIR__);

$dompdf = new Dompdf($options);

$dompdf->setPaper("A4", "Landscape");

$html = file_get_contents("template.html");

$html = str_replace(["{{ name }}", "{{ quantity }}"], [$name, $quantity], $html);

$dompdf->loadHtml($html);
$dompdf->render();

$dompdf->addInfo("Title", "An Example PDF");

$dompdf->stream("example.pdf", ["Attachment" => 0]);
