网址重写的新手问题

Question

I have few questions and I need your advice. So I'm building mini CMS system where users submit content and I construct an url from their content's headline and id eg "74/my-name-is-john-stewart" and insert it to DB besides original context. When I retrieve data with GET method deal?url=74/my-name-is-john-stewart I wonder how to convert that link to deal/74/my-name-is-john-stewart format like in Stackoverflow. And I have doubts if it's a proper way, cause when user deletes id number part, different content is loaded, but url's title part stays the same. I'm afraid , maybe it might cause some SEO problems in the future?

Answer 1

You can use these rules in /deal/.htaccess :

RewriteEngine On
RewriteBase /deal/

RewriteCond %{THE_REQUEST} \s/+(deal)\?url=([^\s&]+) [NC]
RewriteRule ^ /%1/%2? [R=302,L]

# internal forward from pretty URL to actual one
RewriteRule ^([^/.]+)/?$ ?q=$2 [L,QSA,NC]
