如何使用品牌名称插入元数据和网址

actually i want to add metadata for my sitemap page in opencart, so how i can add title description and keywords in sitemap page, is there any code to add in that page please?

My site title tag look like this <title></title> when I see my sitemap page and see in view source then i see this tag without any word so i want to add some title between that tag

2nd question about

I need to change url from

Mysite.com/productname

To

Mysite.com/category/brand/productname

Exactly. You need to re-word the question and bother searching this site.

OpenCart Admin -> Catalog -> Categories -> Name -> Data Tab -> SEO Keyword:

brand/category (example) oasis/shoes

OpenCart Admin -> Catalog -> Products -> Name -> Data Tab -> SEO Keyword:

??-the-product-name (product ID)

56-red-trainers

Nginx: (.htaccess for Apache similar, also with Apache .htaccess this is already standard after enabling Opencart SEO Urls, nginx requires manual work)

server {
    listen  80;
    server_name site.com www.site.com;
    root /var/www/www.site.com/web;
    index index.php index.html index.htm;
    location /admin {
        index index.php;
    }
    location / {
        try_files $uri @opencart;
        # cat
        rewrite ^/oasis/shoes?$ /index.php?route=product/category&path=1 last;

        # product
        rewrite ^/oasis/shoes/(.*)$ /index.php?route=product/product&path=2&product_id=$1 last;
    }
    location @opencart {
        rewrite ^/(.+)$ /index.php?route=$1 last;
    }
    location = /favicon.ico {
        log_not_found off;
        access_log off;
    }
    location = /robots.txt {
        allow all;
        log_not_found off;
        access_log off;
    }         
    location ~* \.(engine|inc|info|ini|install|make|module|profile|test|po|sh|.*sql|theme|tpl(\.php)?|xtmpl)$|^(\..*|Entries.*|Repository|Root|Tag|Template)$|\.php_ {
        deny all;
    }
    location ~ /\. {
        deny all;
        access_log off;
        log_not_found off;
    }
    location ~*  \.(jpg|jpeg|png|gif|css|js|ico)$ {
        expires max;
        log_not_found off;
    }
    location ~ \.php$ {
        include /etc/nginx/fastcgi_params;
        fastcgi_pass    127.0.0.1:9000;
        fastcgi_param   SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }
}

Makes URLS

site.com/oasis/shoes
site.com/oasis/shoes/56-red-trainers
