block cart module

[isaac.dvory]

Hello, 

I'm trying to edit blockcart module because I want to only display link to the cart in the site Nav bar. 

There was already a hook for displaynav but it still loaded the full blockcart file which isn't what I wanted, I just want a link to the cart with a little image of a cart. 

What I did is edit blockcart.php to call nav.tpl (which I added to my theme folder only) :

public function hookRightColumn($params)
	{
		if (Configuration::get('PS_CATALOG_MODE'))
			return;

		// @todo this variable seems not used
		$this->smarty->assign(array(
			'order_page' => (strpos($_SERVER['PHP_SELF'], 'order') !== false),
			'blockcart_top' => (isset($params['blockcart_top']) && $params['blockcart_top']) ? true : false,
		));
		$this->assignContentVars($params);
		if (isset($params['blockcart_tpl']) && $params['blockcart_tpl']) {
			return $this->display(__FILE__, 'nav.tpl');
		}
		return $this->display(__FILE__, 'blockcart.tpl');
	}

It works but the problem I'm having is that the CSS file for blockcart does not load. it seems to only load when header hook is active, which I don't want. I checked that hook and it does have : 

$this->context->controller->addCSS(($this->_path).'blockcart.css', 'all');

but when I try to add the same to my IF , it still does not load that module css. 

 

Please help : ) 

 

Thanks
