trying to figure out how to rewrite this url clientside
blog.com/post/how-to-get-the-ladies
to point serverside to
blog.com/post.php?id=123
i know how to do this:
blog.com/post/123
RewriteRule ^([^/]+)/?$ post.php?id=$1 [NC,L]
but how do you replace the id string with the post title slug?
回答1:
The webserver itself doesn't make this distinction and cannot translate from your "unique text identifier" to the database id. Therefore a .htaccess rule alone evaluated by the webserver will not help you. But how is it done on all those web-applications? Normally this translation is done by Joomla/Wordpress itself and it only works as long the "how_to_get_the_ladies" text is known and unique throughout the system/database.

you can add rule that go to index file like :
RewriteRule ^(.*)$ index.php?url=$1
and in this file according to the title you can show the post that request

I solved a similar problem recently. I would suggest looking into the RewriteMap directive and using an 'External Rewriting Program'.
There are some big limitations with RewriteRule in terms of maintainability and robustness. If you haven't gotten there yet you may eventually. Only simple rewriting rules can be written safely.
With a rewriteMap you can create a php or perl script, take advantage of your existing code base, and perform all the rewriting rules from a localized place in your code which easily sits in version control.
I believe you need access to the httpd.conf (or vhost) configuration file though, RewriteMaps (or some related directive) cannot be put in .htaccess files.
