[Please preview] generate custom PDF in module

[ps8modules.com]

Hi to all.
I need to add my own html template to the module and generate a PDF.

I made HTMLTemplateCustomPdf.php

<?php

class HTMLTemplateCustomPdf extends HTMLTemplate
{
	public $custom_model;

	public function __construct($custom_object, $smarty)
	{
		$this->custom_model = $custom_object;
		$this->smarty = $smarty;

		$id_lang = Context::getContext()->language->id;
		$this->title = HTMLTemplateCustomPdf::l('Custom Title');
		$this->shop = new Shop(Context::getContext()->shop->id);
	}

	public function getContent()
	{
		$this->smarty->assign(array(
			'custom_model' => $this->custom_model,
		));

		return $this->smarty->fetch(_PS_MODULE_DIR_.'my_module/pdf/template.tpl');
	}

	
	public function getFilename()
	{
		return 'custom_pdf.pdf';
	}


	public function getBulkFilename()
	{
		return 'custom_pdf.pdf';
	}
}

 

In the module I call the function for generating PDF:

$custom_object = array('data' => 'test data');
require_once (_PS_MODULE_DIR_ . 'my_module/pdf/HTMLTemplateCustomPdf.php');
$pdf = new PDF($custom_object, 'CustomPdf', Context::getContext()->smarty);
$pdf->render();

 

I get an error:

Can anyone help me with this?

Thank you

No help?

I need to create my own tpl template.
I need to send data to a tpl template.
I need to create a PDF from both FO and BO.

Is it really that complicated?

What is your PrestaShop version?

I see the error: get_class() expects parameter 1 to be object, string given.
