按以上逻辑，应该获取的是下面的模板
app\design\frontend\default\theme508\template\checkout\cart\sidebar\default.phtml

但是在less var/log/system.log 中找到如下错误

CRIT (2): Not valid template file:frontend/base/default/template/ajax/checkout/cart/sidebar/default.phtml

可见是去取了其他地方的模板

app\code\local\Excellence\Ajax\Block\Cart\Sidebar.php

<?phpclass Excellence_Ajax_Block_Cart_Sidebar extends Mage_Checkout_Block_Cart_Sidebar{public function getItemRenderer($type){if (!isset($this->_itemRenders[$type])) {$type = 'default';}if (is_null($this->_itemRenders[$type]['blockInstance'])) {$this->_itemRenders[$type]['blockInstance'] = $this->getLayout()->createBlock($this->_itemRenders[$type]['block'])->setTemplate('ajax/checkout/cart/sidebar/default.phtml')->setRenderedBlock($this);}if (is_null($this->_itemRenders[$type]['blockInstance'])) {$this->_itemRenders[$type]['blockInstance'] = $this->getLayout()->createBlock($this->_itemRenders[$type]['block'])->setTemplate('ajax/checkout/cart/sidebar_header.phtml')->setRenderedBlock($this);}return $this->_itemRenders[$type]['blockInstance'];}}

注释了还是没解决问题

故将 cp /home/promlove/public_html/app/design/frontend/default/theme508/template/checkout/cart/sidebar/default.phtml 复制到

/home/promlove/public_html/app/design/frontend/base/default/template/ajax/checkout/cart/sidebar/default.phtml 

done!
