完美解决zencart SEO模块存在重复网址的问题

encart老鸟们都知道, 当你修改zencart 分类名称或者商品名称后,修改后的URL和修改前的不同的,而且修改前的URL还是可以打开. 这样就会出现完全相同的两个页面, 这样的页面对搜索引擎来说是很不友好的. 这个就是seo模板存在的网址重复问题,下面是解决方案:
第一步: 商店设置－搜索引擎优化－打开自动跳转吗?，设置为 true (这一步非常重要)

第二步: 打开文件/includes/classes/seo.url.php 找到如下代码
$this->attributes['SEO_REDIRECT']['NEED_REDIRECT'] = $this->need_redirect ? 'true' : 'false';
在它前面加上如下代码:
// check product name from URL and redirect if not equal to real product name to avoid duplicates

if ( preg_match(‘/-p-[0-9]/i’, $this->uri) && preg_match(‘/main_page=product_info/i’, $this->real_uri) ) {

$productname_from_url = preg_replace(‘/-p-[0-9].*/i’,”,$this->uri);

$productid_from_url= preg_replace(‘/.*-p-([0-9]+).html/i’,'$1′,$this->uri);

if ( $this->get_product_name($productid_from_url) != $productname_from_url ) {

$this->need_redirect = true;

// repeating procedure from function check_redirect() but for real_uri

if ($this->is_attribute_string($this->real_uri)) {

$parsed_url = parse_url($this->real_uri);

$this->uri_parsed = parse_url($parsed_url['scheme']);

$this->uri_parsed['query'] = preg_replace(‘/products_id=([0-9]+)/’, ‘products_id=$1:’ . $parsed_url['path'], $this->uri_parsed['query']);

} else {

$this->uri_parsed = parse_url($this->real_uri);

}

}

} // end of product_info URL redirect
// check category name from URL and redirect if not equal to real category name to avoid duplicates

if ( preg_match(‘/-c-[0-9]/i’, $this->uri) && preg_match(‘/main_page=index/i’, $this->real_uri) ) {

$categoryname_from_url = preg_replace(‘/-c-[0-9].*/i’,”,$this->uri);

$categoryid_from_url= preg_replace(‘/.*-c-([0-9]+).html/i’,'$1′,$this->uri);

if ( $this->get_category_name($categoryid_from_url) != $categoryname_from_url ) {

$this->need_redirect = true;

// repeating procedure from function check_redirect() but for real_uri

if ($this->is_attribute_string($this->real_uri)) {

$parsed_url = parse_url($this->real_uri);

$this->uri_parsed = parse_url($parsed_url['scheme']);

$this->uri_parsed['query'] = preg_replace(‘/cPath=([0-9]+)/’, ‘cPath=$1:’ . $parsed_url['path'], $this->uri_parsed['query']);

} else {

$this->uri_parsed = parse_url($this->real_uri);

}

}

} // end of category URL redirect
