Combining two cart overrides

[sickz]

Hello,

im trying to combine two diferent cart overrides because i need them both so all my modules work how they should.

 

But it seems like it does not work. I always just get a blank page. If someone could help me it would be appreaciated. I tryed diferent methods but got no result.

 

<?php
/**
* Cart class override for additional payment fees module
* Upload this to the override/clases directory
*
* @author Burhan
* www.bvkyazilim.com
*/
class Cart extends CartCore{	   

public function getOrderTotal($withTaxes = true, $type = Cart::BOTH)
{
	    if($withTaxes && ($type == Cart::BOTH || $type == Cart::ONLY_DISCOUNTS)){
		    $backtrace=debug_backtrace(false);
		    $name=false;
		    if(isset($backtrace[0]) && stristr($backtrace[0]['file'], 'modules')){
			    $name=explode(DIRECTORY_SEPARATOR, $backtrace[0]['file']);
		    }elseif(isset($backtrace[1]) && stristr($backtrace[1]['file'], 'modules')){
			    $name=explode(DIRECTORY_SEPARATOR, $backtrace[1]['file']);
		    }
		    if($name)
			    $name=$name[array_search('modules', $name)+1];
		    if($name){
			    if($fee=Db::getInstance()->getValue('SELECT `fee` FROM `'._DB_PREFIX_.'bvk_paymentfees` WHERE `name`="'.pSQL($name).'"')){
				    if($type == Cart::ONLY_DISCOUNTS){
					    $result=parent::getOrderTotal($withTaxes, $type);
					    if(!$result){
						    $result='a';
					    }
					    return $result;
				    }
				    $fee='$total='.str_replace('total', '$total', $fee);
				    $total=parent::getOrderTotal($withTaxes, $type);
				    $tmp=$total;
				    eval($fee.';');
				    $total=Tools::ps_round($total, 2);
				    $feeamount=$total-$tmp;
				    Db::getInstance()->Execute('REPLACE INTO `'._DB_PREFIX_.'bvk_paymentfees_cart`(`id_cart`, `name`, `fee`) VALUES('.intval($this->id).', "'.pSQL($name).'", '.floatval($feeamount).')');
				    return $total;
			    }
		    }
	    }
	    return parent::getOrderTotal($withTaxes, $type);
}
}

turn on errors in config/config.inc.php to see if you get an error message
