语法错误

Question

我正在尝试自定义magento的价格分层导航这个线程： http://www.magentocommerce.com/boards/viewthread/65135/P15/#t278667

但是当我复制并粘贴他的代码时，我遇到了错误，请参阅下面的代码。 有什么想法吗？

protected function _getItemsData()
{
    $key = $this->_getCacheKey();

    $data = $this->getLayer()->getAggregator()->getCacheData($key);
    if ($data === null) {
        $range      = 100;// $this->getPriceRange();
        $minEntries = 30;
        $minPercentage = 12; //overrides the previous line if set, sets minEntries to $minPercentage of total items
        $lastRange  = 5000; //collects everything over this value into one range, must be a multiple of $range. Set to 0 for no last range.
        $lastRangeIndex = $lastRange == 0 ? 0 : intval($lastRange / $range);

        if ( ($minPercentage > 0) && ($minPercentage < 100) ) {
            $itemCount = array_sum($dbRanges);
            $minEntriesByPercentage = intval( $itemCount * ($minPercentage / 100) );
            $minEntries = $minEntriesByPercentage;

目前

if ( ( ( $collect + $count ) >= $minEntries ) && ( ($index <= $lastRangeIndex) || ($lastRangeIndex == 0) ) {

对于if语法，

缺少“）”：

if ( ( ( $collect + $count ) >= $minEntries ) && ( ($index <= $lastRangeIndex) || ($lastRangeIndex == 0) )) {
