pdf_using_mpdf

Introduction

• Use this module to convert HTML to PDF using the mPDF PHP Library
• Use this module to create editable PDF files

Requirements

• If the mPDF library is not installed automatically: Use below composer command to install the library from the directory where your composer.json is!

 composer require 'mpdf/mpdf:^8.2'

Configuration

• Go to this URL and set your PDF preferences : /admin/config/user-interface/mpdf
• Set permissions for which roles can generate a PDF document : /admin/people/permissions

Usage

• This module provides PDF generation for nodes out-of-the-box >> full view mode, by default.
• After permissions have been set for node types, use Generate PDF URL on node view to generate a valid PDF
• For any other entity, or an HTML, refer below the developer guide.

For Developers

• Use a custom Drupal service pdf_using_mpdf.conversion for PDF generation
• This service primarily needs HTML output.
• To generate a PDF programmatically from anywhere in your project, use the following:

  /** @var \Drupal\pdf_using_mpdf\ConvertToPdfInterface $pdf */
  $pdfService = \Drupal::service('pdf_using_mpdf.conversion');
  $pdfService->convert($html, $settings, $context);

Parameters used above :
-----------------------
$html                 > Rendered HTML of an entity or HTML tags in string format.
$settings (optional)  > Use this parameter to overwrite settings from the configuration page.
$context  (optional)  > Useful to replace tokens set in the mPDF configuration.

• For even better control, checkout pdf_using_mpdf.api.php file to look at the hooks provided by this module.
• With these hooks, you can use a separate set of mPDF settings for every use case.
