How can I create dynamic pdf files from a page

@dean_007, Yes, it may have solved the error, but it is a bit crude…

I would do the following to better align with PHP PSR-1 codestyle, Composer autoloading and Grav itself:

  • Create a plugin using $ bin/plugin devtools newplugin and name it ProductPDF
    Judging from your code, it seems you’ve used this utility.
  • $ cd user/plugins/product-pdf
  • $ composer require tecnickcom/tcpdf
    Note require instead of required
  • Create file /user/plugins/product-pdf/classes/MyPDF.pdf, with the following content:
    <?php
namespace Grav\Plugin\ProductPDF;

use TCPDF;

class MyPDF extends TCPDF {
    public $logoPath;
    public $product;
    public $dxfIconPath;
    public $dxfFilePath;

    public function Header() {
        // Code
    }

    public function Footer() {
        // Code
     }
}
    Note the CamelCase naming convention for both the file and class.
  • Make the following changes in file /user/plugins/product-pdf/product-pdf.php:
    • Add use Grav\Plugin\ProductPDF\MyPDF;
    • Don’t use require __DIR__ . '/vendor/autoload.php';
      public function autoload() will be called by Grav when plugin is initialized.
    • Remove use TCPDF;
    • Remove entire class MYPDF
    • Replace $pdf = new MYPDF(...) with $pdf = new MyPDF(...)
