Blade (PHP)

This guide explains how to generate an HTML string using PHP's Blade template engine and convert it to PDF by sending it to pdfg's API.

Technical Overview

Create a Blade template
Pass data to the template to generate an HTML string
Send the generated HTML string to pdfg's API to convert it to PDF

Sample

Defining the Template

{{-- templates/invoice.blade.php --}}
<!DOCTYPE html>
<html>
  <head></head>
  <body>
    <div class="invoice">
      <h1>Invoice</h1>
      <table>
        <thead>
          <tr>
            <th>Item</th>
            <th>Amount</th>
          </tr>
        </thead>
        <tbody>
          @foreach ($items as $item)
            <tr>
              <td>{{ $item['name'] }}</td>
              <td>{{ $item['price'] }} USD</td>
            </tr>
          @endforeach
        </tbody>
      </table>
      <p class="total">Total: {{ $total }} USD</p>
    </div>
  </body>
</html>

Using the Template and Generating PDF

<?php
// generate_pdf.php
require 'vendor/autoload.php';
use Illuminate\View\Factory;
use Illuminate\View\FileViewFinder;
use Illuminate\View\Engines\CompilerEngine;
use Illuminate\View\Engines\EngineResolver;
use Illuminate\View\Compilers\BladeCompiler;
use Illuminate\Filesystem\Filesystem;

// Configure Blade engine
$files = new Filesystem;
$compiler = new BladeCompiler($files, 'cache');
$resolver = new EngineResolver;
$resolver->register('blade', function () use ($compiler) {
    return new CompilerEngine($compiler);
});
$finder = new FileViewFinder($files, ['templates']);
$factory = new Factory($resolver, $finder, new Illuminate\Events\Dispatcher);

// Prepare data
$items = [
    ['name' => '商品A', 'price' => 1000],
    ['name' => '商品B', 'price' => 2000],
];
$total = 3000;

// Generate HTML string
$html = $factory->make('invoice', [
    'items' => $items,
    'total' => $total,
])->render();

// Request to pdfg's API
$ch = curl_init('https://api.pdfg.net/v1');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, [
    'Content-Type: application/json',
    'Authorization: Bearer YOUR_API_KEY'
]);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode([
    'html' => $html,
    'pdfOptions' => [
        'format' => 'A4'
    ]
]));

$response = curl_exec($ch);
$httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);

// Save PDF
if ($httpCode === 200) {
    file_put_contents('invoice.pdf', $response);
}
