我一直在研究opencart的SEO URL。我使用扩展程序（SEO Keyword Lite）在opencart 2.3.0.2中管理SEO URL。问题是，当我将任何产品或类别的SEO URL添加到不超过1个细分，即http://baseurl/product-name时，它工作正常，但是当我将SEO URL最多添加2个细分，即http://baseurl/product/product-name时，它显示错误“找不到所请求的页面！”
我的Seo网址文件：
class ControllerStartupSeoUrl extends Controller {
public function index() {
// Add rewrite to url class
if ($this->config->get('config_seo_url')) {
$this->url->addRewrite($this);
}
// Decode URL
if (isset($this->request->get['_route_'])) {
$parts = explode('/', $this->request->get['_route_']);
// remove any empty arrays from trailing
if (utf8_strlen(end($parts)) == 0) {
array_pop($parts);
}
foreach ($parts as $part) {
$query = $this->db->query("SELECT * FROM " . DB_PREFIX . "url_alias WHERE keyword = '" . $this->db->escape($part) . "'");
if ($query->num_rows) {
$url = explode('=', $query->row['query']);
if ($url[0] == 'product_id') {
$this->request->get['product_id'] = $url[1];
}
if ($url[0] == 'category_id') {
if (!isset($this->request->get['path'])) {
$this->request->get['path'] = $url[1];

$this->request->get['path'] .= '_' . $url[1];
}

$this->request->get['manufacturer_id'] = $url[1];

if ($url[0] == 'information_id') {
$this->request->get['information_id'] = $url[1];

if ($query->row['query'] && $url[0] != 'information_id' && $url[0] != 'manufacturer_id' && $url[0] != 'category_id' && $url[0] != 'product_id') {
$this->request->get['route'] = $query->row['query'];
}

}
public function rewrite($link) {
$url_info = parse_url(str_replace('&', '&', $link));
$url = '';
$data = array();
parse_str($url_info['query'], $data);

我在每个步骤上都尝试过print_r（）并尝试了我的解决方案，但它显示未找到相同的请求。我了解的是seo url相应地命中了，但是它找不到与该url相关的资源，并且显示“找不到请求”。我是新来的要打开购物车的人，如果有人在此指导我，我将不胜感激。谢谢。
我找到了设置SEO URL的答案，只需在重写功能中放入几行代码：
public function rewrite($link) {
$url_info = parse_url(str_replace('&', '&', $link));
$url = '';
$data = array();
parse_str($url_info['query'], $data);
if ($data['route'] == 'common/home'){
$url .= '/';
}
if ($data['route'] == 'information/contact'){
$url .= '/contact';
}
if ($data['route'] == 'account/return/add'){
$url .= '/returnadd';
}
if ($data['route'] == 'information/sitemap'){
$url .= '/sitemap';
}
if ($data['route'] == 'product/manufacturer'){
$url .= '/manufacturer';
}
if ($data['route'] == 'account/voucher'){
$url .= '/voucher';
}
if ($data['route'] == 'affiliate/login'){
$url .= '/affiliatelogin';
}
if ($data['route'] == 'product/special'){
$url .= '/special';
}
if ($data['route'] == 'product/product'){
$url .= '/product';
}
if ($data['route'] == 'product/category'){
$url .= '/category';
}
if ($data['route'] == 'account/login'){
$url .= '/login';
}
if ($data['route'] == 'checkout/cart'){
$url .= '/cart';
}
foreach ($data as $key => $value) {
if (isset($data['route'])) {
if (($data['route'] == 'product/product' && $key == 'product_id') || (($data['route'] == 'product/manufacturer/info' || $data['route'] == 'product/product') && $key == 'manufacturer_id') || ($data['route'] == 'information/information' && $key == 'information_id')) {
$query = $this->db->query("SELECT * FROM " . DB_PREFIX . "url_alias WHERE `query` = '" . $this->db->escape($key . '=' . (int)$value) . "'");
if ($query->num_rows && $query->row['keyword']) {
$url .= '/' . $query->row['keyword'];
unset($data[$key]);
}
} elseif ($key == 'path') {
$categories = explode('_', $value);
foreach ($categories as $category) {
$query = $this->db->query("SELECT * FROM " . DB_PREFIX . "url_alias WHERE `query` = 'category_id=" . (int)$category . "'");
if ($query->num_rows && $query->row['keyword']) {
$url .= '/' . $query->row['keyword'];
} else {
$url = '';
break;
}
}
unset($data[$key]);
}
}
}
if ($url) {
unset($data['route']);
$query = '';
if ($data) {
foreach ($data as $key => $value) {
$query .= '&' . rawurlencode((string)$key) . '=' . rawurlencode((is_array($value) ? http_build_query($value) : (string)$value));
}
if ($query) {
$query = '?' . str_replace('&', '&', trim($query, '&'));
}
}
return $url_info['scheme'] . '://' . $url_info['host'] . (isset($url_info['port']) ? ':' . $url_info['port'] : '') . str_replace('/index.php', '', $url_info['path']) . $url . $query;
} else {
return $link;
}
}
最重要的是，在oc_url_alias中提及这些关键字，例如：
query= product/category keyword=category
我希望这将对许多面临seo url问题的人有所帮助。
谢谢。
