Question

I want to rewrite some URL’s based only on the last parameter. For example:

http://www.site.com/some-param/some-param/THIS-param

I want to grab THIS-param and use that for the rewrite. It always be the last parameter, but not necessarily the 3rd. Could be 2nd, 3rd, 4th, or 5th.

Im getting close with this:

RewriteRule ([^/]+)$ index.php?url_title=$1 [NC,L,QSA]

using this as the url (for example).

http://www.test.com/param1

The problem is, once I add ‘param2’ the site stops working. I think it’s cause param1 appear to be a directory.

http://www.test.com/param1/param2

Any idea why? Here’s my full set of rules:

Options +FollowSymlinks -MultiViews

RewriteEngine on

RewriteCond %{REQUEST_FILENAME} -f [NC,OR] 
RewriteCond %{REQUEST_FILENAME} -d [NC] 
RewriteRule .* - [L]

RewriteRule ([^/]+)$ index.php?url_title=$1 [NC,L,QSA]
RewriteRule .* index.php [L]

Answer 1

You nearly had it. You need to capture everything that comes after the last /, and optionally capture what comes before it if needed. You said it coudld be 2nd through 5th, but didn’t mention 1st, so that assumes something comes before it with a /, as in ^.+/.

This also allows for a trailing /

Edited to incorporate existing rules:

RewriteEngine On

# Real existing files not rewritten
RewriteCond %{REQUEST_FILENAME} -f [NC,OR] 
RewriteCond %{REQUEST_FILENAME} -d [NC] 
RewriteRule .* - [L]

#Inelegant hack to permit one param only
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)/?$ index.php?url_title=$1 [L,QSA]
RewriteRule ^.+/([^/]+)/?$ index.php?url_title=$1 [L,QSA]
# Anything not matching above goes to index.php
RewriteRule .* index.php [L]
