请问有什么解决方案吗？

Answer 1

请检查您的文件可能是您离开

回声， Zend_Debug :: dump（），的print_r（）

如果您对这些进行评论，那么您可以;面对“无法发送标题;标题已发送”问题

如果问题仍未解决，则将文件顶部的空格留下

所以请两个选项，你将解决你自己的问题

感谢您的回答！

echo中没有Zend_Debug::dump()，print_r()，observer.php。

这是内容：

class BTS_Checkout_Model_Observer {

    private $_shippingCode = 'royalmail';
    private $_country = 'DE';

    public function addShipping($params = null) {
        if (Mage::registry('checkout_addShipping')) {
            Mage::unregister('checkout_addShipping');
            return;
        }
        Mage::register('checkout_addShipping',true);

        $cart = Mage::getSingleton('checkout/cart');
        $quote = $cart->getQuote();

        if ($quote->getCouponCode() != '') {
            $c = Mage::getResourceModel('salesrule/rule_collection');
            $c->getSelect()->where("code=?", $quote->getCouponCode());
            foreach ($c->getItems() as $item) { $coupon = $item; }

            if ($coupon->getSimpleFreeShipping() > 0) {
                $quote->getShippingAddress()->setShippingMethod($this->_shippingCode)->save();
                return true;
            }
        }

        try {
            $method = $quote->getShippingAddress()->getShippingMethod();
            if ($method) return; // don't overwrite what's already there if we have one set already

            if ($quote->getShippingAddress()->getCountryId() == '') {
                $quote->getShippingAddress()->setCountryId($this->_country);
            }

            $quote->getShippingAddress()->setCollectShippingRates(true);
            $quote->getShippingAddress()->collectShippingRates();

            $rates = $quote->getShippingAddress()->getAllShippingRates();
            $allowed_rates = array();
            foreach ($rates as $rate) {
                array_push($allowed_rates,$rate->getCode());
            }

            if (!in_array($this->_shippingCode,$allowed_rates) && count($allowed_rates) > 0) {
                $shippingCode = $allowed_rates[0];
            }

            if (!empty($shippingCode)) {
                $address = Mage::getSingleton('checkout/session')->getQuote()->getShippingAddress();
                if ($address->getCountryId() == '') $address->setCountryId($this->_country);
                if ($address->getCity() == '') $address->setCity('');
                if ($address->getPostcode() == '') $address->setPostcode('');
                if ($address->getRegionId() == '') $address->setRegionId('');
                if ($address->getRegion() == '') $address->setRegion('');
                $address->setShippingMethod($this->_shippingCode)->setCollectShippingRates(true);
                Mage::getSingleton('checkout/session')->getQuote()->save();
            } else {
                $address = Mage::getSingleton('checkout/session')->getQuote()->getShippingAddress();
                if ($address->getCountryId() == '') $address->setCountryId($this->_country);
                if ($address->getCity() == '') $address->setCity('');
                if ($address->getPostcode() == '') $address->setPostcode('');
                if ($address->getRegionId() == '') $address->setRegionId('');
                if ($address->getRegion() == '') $address->setRegion('');
                $address->setShippingMethod($this->_shippingCode)->setCollectShippingRates(true);
                Mage::getSingleton('checkout/session')->getQuote()->save();
            }

            Mage::getSingleton('checkout/session')->resetCheckout();

        }
        catch (Mage_Core_Exception $e) {
            Mage::getSingleton('checkout/session')->addError($e->getMessage());
        }
        catch (Exception $e) {
            Mage::getSingleton('checkout/session')->addException($e, Mage::helper('checkout')->__('Load customer quote error'));
        }


    }

    public function getQuote() {
        if (empty($this->_quote)) {
            $this->_quote = Mage::getSingleton('checkout/session')->getQuote();
        }
        return $this->_quote;
    } 
}
