Sorry, I am not on this forum often, but here are my changes:

2 files:

• libraries/src/Document/PdfDocument.php, adapted from libraries/joomla/document/pdf/pdf.php
  administrator/components/com_phocapdf/helpers/phocapdfrender.php, for the fix for custom pdf plugins

Code: Select all

<?php

namespace Joomla\CMS\Document;

defined('JPATH_PLATFORM') or die;

use Joomla\Filesystem\File;
use Joomla\CMS\Factory;

class PdfDocument extends Document
{ 
	// Document
	public $_generator	= 'Phoca PDF';
	public $_charset 	= 'utf-8';
	public $_mime 		= 'application/pdf';

	// PDF (Html)
	public $_links 		= array();

	// PDF
	public $_header			= null;

		return $this->_header;
	}

	function setName($name = 'Phoca') {

	}

	function getName() {
		return $this->_name;
	}
	
	function setArticleText($text) {
		$this->_article_text = $text;
	}

	function getArticleText() {

	}
	
	function setArticleTitle($text) {

	}

	function getArticleTitle() {
		return $this->_article_title;
	}

	function render( $caching = false, $params = array()) {
		
		$app = \JFactory::getApplication();
		
		//$this->_caching = $caching;
		//Call static function because of using on different places by different extensions
		if (\JFile::exists(JPATH_ADMINISTRATOR.'/components/com_phocapdf/helpers/phocapdfrender.php')) {

		}

		parent::render();
		
		$data = \PhocaPdfRender::renderPDF($this);

		return $data;
	}
	
	function addCustomTag() {	
		return true;
	}

	public function setHeadData($data)
	{

		$this->_custom		= array();//(isset($data['custom']) && !empty($data['custom'])) ? $data['custom'] : $this->_custom;	
	}
}

and in the phocapdfrender.php starting at line 154:

Code: Select all

			default:
			   $dispatcher   = JDispatcher::getInstance();
			   if (JPluginhelper::isEnabled('phocapdf',strtolower($t))){
				  JPluginHelper::importPlugin( 'phocapdf' );
				  $results = $dispatcher->trigger('onBeforeCreatePDF'.$t, array(&$content));
				  require_once(JPATH_ADMINISTRATOR.DS.'components'.DS.'com_phocapdf'.DS.'helpers'.DS.'phocapdfcontenttcpdf.php');
				  $pdf = new PhocaPDFContentTCPDF($content->page_orientation, 'mm', $content->page_format, true, 'UTF-8', $content->use_cache);
				  $results = $dispatcher->trigger('onBeforeDisplayPDF'.$t, array (&$pdf, &$content, &$document));
			   } else {
				  return JError::raiseError('PDF ERROR', 'Phoca PDF - '.$t.' plugin is disabled or not installed');
			   }
			break;

Wow, that works - thanks a lot! Let me get you a coffee :)

Hi, thank you for the info, I hope I will release the next version today.

In this code some obsolete methods were removed too:

- DS
- JDispatcher
- JError

In render function these methods are missing:

\JFactory::getApplication()->setHeader('Content-type', 'application/pdf', true);// Because of cache
\JFactory::getApplication()->setHeader('Content-disposition', 'inline; filename="'.$this->getName().'.pdf"', true);
