篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了如何在OpenCart中创建自定义SEO友好的URL？相关的知识，希望对你有一定的参考价值。
如何在OpenCart中自定义系统URL？例如，我希望http://example.com/index.php?route=checkout/cart显示为http://example.com/cart
我知道OpenCart为产品，类别，制造商和信息页面提供了SEO URL，但看起来并没有内置任何内容（至少在1.5.0版之前）。
答案
事实证明，这可以通过对单个文件进行相对简单的更改来完成。没有.htaccess重写规则，只需修补catalog / controller / common / seo_url.php文件，并将漂亮的URL添加到现有的数据库表中。
seo_url.php的补丁：
Index: catalog/controller/common/seo_url.php

需要进行两次编辑。第一个扩展index()函数，在url_alias表中查找与$this->request->get['_route_']匹配的任何关键字。
第二个扩展了rewrite()函数，在url_alias表中查找所有路径，而不仅仅是产品，制造商和信息页面。
向数据库添加条目：
INSERT INTO `url_alias` (`url_alias_id`, `query`, `keyword`) VALUES
(NULL, 'checkout/cart', 'cart');
而已。 http://example.com/cart应该返回与http://example.com/index.php?route=checkout/cart相同的东西，OpenCart应该识别$this->url->link('checkout/cart');并返回漂亮的URL http://example.com/cart的链接
另一答案
我正在使用Opencart版本1.5.5.1，这是对我有用的确切代码：
<?php
class ControllerCommonSeoUrl extends Controller {
/* SEO Custom URL */
private $url_list = array (
'common/home' => '',
'checkout/cart' => 'cart',
'account/register' => 'register',
'account/wishlist' => 'wishlist',
'checkout/checkout' => 'checkout',
'account/login' => 'login',
'product/special' => 'special',
'affiliate/account' => 'affiliate',
'checkout/voucher' => 'voucher',
'product/manufacturer' => 'brand',
'account/newsletter' => 'newsletter',
'account/order' => 'order',
'account/account' => 'account',
'information/contact' => 'contact',
'account/return/insert' => 'return',
'information/sitemap' => 'sitemap',
);
/* SEO Custom URL */
public function index() {
// Add rewrite to url class
if ($this->config->get('config_seo_url')) {
$this->url->addRewrite($this);
}
// Decode URL
if (isset($this->request->get['_route_'])) {
$parts = explode('/', $this->request->get['_route_']);
foreach ($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];
} else {
$this->request->get['path'] .= '_' . $url[1];
}
}
if ($url[0] == 'manufacturer_id') {
$this->request->get['manufacturer_id'] = $url[1];
}
if ($url[0] == 'information_id') {
$this->request->get['information_id'] = $url[1];
}
} else {
$this->request->get['route'] = 'error/not_found';
}
}
/* SEO Custom URL */
if ( $_s = $this->setURL($this->request->get['_route_']) ) {
$this->request->get['route'] = $_s;
}/* SEO Custom URL */
if (isset($this->request->get['product_id'])) {
$this->request->get['route'] = 'product/product';

$this->request->get['route'] = 'information/information';
}
if (isset($this->request->get['route'])) {
return $this->forward($this->request->get['route']);
}
}
}
public function rewrite($link) {
$url_info = parse_url(str_replace('&', '&', $link));
$url = '';
$data = array();
parse_str($url_info['query'], $data);
foreach ($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) {

}

}
unset($data[$key]);
}
/* SEO Custom URL */
if( $_u = $this->getURL($data['route']) ){

}
}
if ($url) {
unset($data['route']);
$query = '';
