OpenCart搜索引擎增强小程序（1.46通过）

sunboy

假如一个产品的标题是 AA BB CC，那么正常情况下需要搜索AA, AA BB 或者BB CC（从左到右的顺序）如果顺序不对则搜索不出来

不过稍作改动我们就可以无视顺序的使用搜索了

使用DREAMWEAVER新建文件，写入以下代码后保存为"product.php"，将该文件上传至catalog/model/catalog/替换源文件就OK，这时你搜索CC AA一样也可以得出想要的结果了

1.4.9适用吗？？

yixuehanfeng

$keywords = preg_split("/[\s,]*\\"([^\\"]+)\\"[\s,]*|" . "[\s,]*'([^']+)[\s,]*|" . "[\s,]+/", $keyword, 0, PREG_SPLIT_NO_EMPTY);这句出现错误
错误代码是
Parse error:syntax error, unexpected '(' in D:\www\opencart\upload\catalog\model\catalog\product.php on line 88
请问怎么解决啊
