Hooking existing module to more different hooks

[CrossY]

Hi there,

 

I would like for the existing module "blockcmsinfo" to show on more pages, so I figured i'd update the hooks for the module.

 

I've edited the file "blockcmsinfo.php" in the module, to include 2 new texts:

$this->registerHook('productfooter'); &&

and 

	public function hookProductFooter($params)
	{
		$this->context->controller->addCSS($this->_path.'style.css', 'all');
		if (!$this->isCached('blockcmsinfo.tpl', $this->getCacheId()))
		{
			$infos = $this->getInfos($this->context->language->id, $this->context->shop->id);
			$this->context->smarty->assign(array('infos' => $infos, 'nbblocks' => count($infos)));
		}

		return $this->display(__FILE__, 'blockcmsinfo.tpl', $this->getCacheId());
	}

However, it gives me an white page as result, or a BOOLEAN error.

 

I'm not a programmer, but I can't see what else i'm missing here..

 

Any suggestions? Thanks in advance!
