Make post title as a slug in url by mod rewrite

I have a url:

http://www.example.com/details.php?var=100&p=99

I want to rewrite it as using mod rewrite

http://www.example.com/100/99

I am using following rewite_rule:

RewriteRule ^([0-9]+)/([0-9]+) $  http://www.example.com/details.php?var=$1&p=$2   [L]

but it is not working. If I type http://www.example.com/100/99 it redirects to http://www.example.com/details.php?var=100&p=99 url. Please help me in this issue. Thanks

Answer 1

The prblem in your approach is

1. ^([1-9]+) the URI starts with / - your telling the rule to check for some digits without /
2. There could be zeros in your URL so having 1-9 will not allow you to have zero.

Try this:

RewriteRule ^/([0-9]*)/([0-9]*) http://www.example.com/details.php?var=$1&p=$2   [L]

Answer 2

If it's about the _redirect_, then remove the http://... prefix from the target part.

RewriteRule ^(\d+)/(\d+)$  details.php?var=$1&p=$2   [L]

Make this the first rule.

Also keep in mind that you have to adapt your application to actually generate /123/456 urls. The rewriterule only works on incoming requests, it does not alter pages.

Answer 3

Include 0 in the regular expression:

RewriteRule ^/([0-9]+)/([0-9]+)/?$  http://www.example.com/details.php?var=$1&p=$2   [L]

The reverse would be:

RewriteCond %{QUERY_STRING} ^var=([0-9]+)\&p=([0-9]+)$ 
RewriteRule ^details\.php$ http://www.example.com/%1/%2 [R=301,L]
