【问题描述】:
我想从我的 opencart 网上商店重写我的产品 url。 Opencart 本身有一个非常糟糕的 seo 实现。我已经更新了 seo 实现,以便能够对多个类别使用相同的关键字,请参阅:Opencart duplicate URL keywords 但这仅适用于类别。对于我认为的产品,我只需要一个 htaccess 重写规则。
原来的网址是这样的:
http://domain.com/index.php?route=product/product&path=25_28_93&product_id=1759
我的网址现在是这样的:
http://domain.com/In-Stock/Retreaded-Tires/Agricultural?product_id=1759
如您所见,类别确实发生了变化。
我希望它是这样的:
http://domain.com/In-Stock/Retreaded-Tires/Agricultural/1759/1050-50R32-Mega-X-Bib
然后对于分页(在一个类别内)我有这个网址:
http://domain.com/index.php?route=product/category&path=36_70_67&page=2
我已经把它做成了:
http://domain.com/Tire-Retreading/Equalizing/&page=2
但我希望是这样的
http://domain.com/Tire-Retreading/Equalizing/2
我的 htaccess 文件如下所示:
Options +FollowSymlinks
Options -Indexes
<FilesMatch "(?i)((\.tpl|\.ini|\.log|(?<!robots)\.txt))">
Order deny,allow
Deny from all
</FilesMatch>
RewriteEngine On
RewriteBase /
RewriteRule ^sitemap.xml$ index.php?route=feed/google_sitemap [L]
RewriteRule ^googlebase.xml$ index.php?route=feed/google_base [L]
RewriteRule ^download/(.*) /index.php?route=error/not_found [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !.*\.(ico|gif|jpg|jpeg|png|js|css)
RewriteRule ^([^?]*) index.php?_route_=$1 [L,QSA]
我的 seo_url.php 文件稍作改动,如下所示:
public function index() {
$this->load->model('catalog/category');
// Add rewrite to url class
if ($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);
}
$categories = array();
for ($i = 0; $i < count($parts); $i++) {
$query = $this->db->query("SELECT * FROM " . DB_PREFIX . "url_alias WHERE keyword = '" . $this->db->escape($parts[$i]) . "'");
if ($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') {
$categories[$i] = $this->model_catalog_category->getCategory($url[1]);
if (!isset($this->request->get['path'])) {
$this->request->get['path'] = $categories[$i]['category_id'];
} else {
foreach ($query->rows as $row) {
$url = explode('=', $row['query']);
$category_id = $url[1];
$category = $this->model_catalog_category->getCategory($category_id);
if ($category['parent_id'] == $categories[$i - 1]['category_id']) {
$this->request->get['path'] .= '_' . $category['category_id'];
}
}
}
}
if ($url[0] == 'manufacturer_id') {
$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'];
}
} else {
$this->request->get['route'] = 'error/not_found';
break;
}
}
if (!isset($this->request->get['route'])) {
if (isset($this->request->get['product_id'])) {
$this->request->get['route'] = 'product/product';
} elseif (isset($this->request->get['path'])) {
$this->request->get['route'] = 'product/category';
} elseif (isset($this->request->get['manufacturer_id'])) {
$this->request->get['route'] = 'product/manufacturer/info';
} elseif (isset($this->request->get['information_id'])) {
$this->request->get['route'] = 'information/information';
}
}
if (isset($this->request->get['route'])) {
return new Action($this->request->get['route']);
}
}
}
public function rewrite($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 && $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]);
} else {
$query = $this->db->query("SELECT * FROM " . DB_PREFIX . "url_alias WHERE `query` = '" .$data['route'] . "'");
if ($query->num_rows && $query->row['keyword']) {
$url .= '/' . $query->row['keyword'];
unset($data[$key]);
}
}
}
}
if ($url) {
unset($data['route']);
$query = '';
if ($data) {
foreach ($data as $key => $value) {
$query .= '&' . rawurlencode((string)$key) . '=' . rawurlencode((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;
}
}
分页代码是这样的:
class Pagination {
public $total = 0;
public $page = 1;
public $limit = 20;
public $num_links = 8;
public $url = '';
public $text_first = '|<';
public $text_last = '>|';
public $text_next = '>';
public $text_prev = '<';
public function render() {
$total = $this->total;
if ($this->page < 1) {
$page = 1;
} else {
$page = $this->page;
}
if (!(int)$this->limit) {
$limit = 10;
} else {
$limit = $this->limit;
}
$num_links = $this->num_links;
$num_pages = ceil($total / $limit);
$this->url = str_replace('%7Bpage%7D', '{page}', $this->url);
$output = '<ul class="pagination">';
if ($page > 1) {
$output .= '<li><a href="' . str_replace('{page}', 1, $this->url) . '">' . $this->text_first . '</a></li>';
$output .= '<li><a href="' . str_replace('{page}', $page - 1, $this->url) . '">' . $this->text_prev . '</a></li>';
}
if ($num_pages > 1) {
if ($num_pages <= $num_links) {
$start = 1;
$end = $num_pages;
} else {
$start = $page - floor($num_links / 2);
$end = $page + floor($num_links / 2);
if ($start < 1) {
$end += abs($start) + 1;
$start = 1;
}
if ($end > $num_pages) {
$start -= ($end - $num_pages);
$end = $num_pages;
}
}
for ($i = $start; $i <= $end; $i++) {
if ($page == $i) {
$output .= '<li class="active"><span>' . $i . '</span></li>';
} else {
$output .= '<li><a href="' . str_replace('{page}', $i, $this->url) . '">' . $i . '</a></li>';
}
}
}
if ($page < $num_pages) {
$output .= '<li><a href="' . str_replace('{page}', $page + 1, $this->url) . '">' . $this->text_next . '</a></li>';
$output .= '<li><a href="' . str_replace('{page}', $num_pages, $this->url) . '">' . $this->text_last . '</a></li>';
}
$output .= '</ul>';
if ($num_pages > 1) {
return $output;
} else {
return '';
}
}
}
编辑:
我的所有页面都重定向到http://domain.com/index.php
从那里它决定从路由参数使用哪个目录/文件。
所以route=product/product 告诉您转到目录产品中的product.php。目录产品还包含categories.php,它指向一条路线:route=product/category
字符串中的 Path 变量表示类别的 ID。在我的示例中,25 代表 In-Stock。而25_28 代表In-Stock/Retreaded-Tires 等。
product_id 变量代表产品对应的 id。
page 变量表示分页,用于类别内的产品列表。该列表可以具有可变长度,因为它计算一个类别中有多少产品以及他应该在一个页面上显示多少。
因此,如果原始 url 有 &page=2 和路由 route=product/category 它应该创建一个这样的 url:http://domain.com/Tire-Retreading/Equalizing/2
【问题讨论】:
-
rewrite方法在哪里,必须在这个controller里面。
-
添加了rewrite方法是我的错误,我把那个方法漏掉了。
-
您能否澄清一下您所说的“更经常使用什么,我应该使用什么”? – 似乎句子末尾缺少一个单词,并且不清楚您要在哪些选项之间做出决定。我对 Opencart 不熟悉,但对 .htaccess 很熟悉。但是,从您提供的 URL 中很难分辨出哪些部分是哪些部分(无需查看所有代码)。您想要的 URL 如何分解成不同的元素? (即原始“丑陋”URL 中的路由、产品、路径、类别等如何转换为所需的“干净”URL?)谢谢。

我已经添加了一些关于变量的细节
