Htaccess URL rewrite question - .htaccess

Question

I have a challenge using Apache.
In my .htaccess file I'd like to convert requests like this:
url/portfolio/filename.htm
to:
url?filename
Any takers? Thanks for your time

Answer 1

You have a couple of choices, depending on how you want the URL to appear to visitors (and search engines).
If you want the externally visible URL to remain url/portfolio/filename.htm, Alec's solution worked after I removed the two RewriteCond lines.
RewriteEngine On
RewriteRule ^(.*)/portfolio/(.*)\.htm$ $1?$2 [PT,L]
If other parameters could be in the query string and you want to preserve those, add QSA to the options in brackets at the end of the rule.
If you want people outside to see url?filename instead, change the rule to:
RewriteRule ^(.*)/portfolio/(.*)\.htm$ $1?$2 [L,R]
Same qualification about other query parameters applies.
If this still doesn't help, I suggest you turn on rewrite logging and look in that log for more clues. Post them here and someone will help. You might have to put this part in httpd.conf. My Apache didn't like it in .htaccess.
RewriteLog ...path...
RewriteLogLevel 3 # you'll regret anything higher

Answer 2

Something like this should work, although I have not tested it.
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# Rewrite all other URLs to index.php/URL
RewriteRule ^(.*)/portfolio/(.*)\.htm$ $1?$2 [PT,L]
</IfModule>
<IfModule !mod_rewrite.c>
ErrorDocument 404 index.php
</IfModule>

Answer 3

This should work:
Options +FollowSymlinks
RewriteEngine on
RewriteRule ^portfolio/(.+)\.htm$ index.php?$1 [NC,L]
or if you want to visibly change it:
Options +FollowSymlinks
RewriteEngine on
RewriteRule ^portfolio/(.+)\.htm$ /?$1 [R,NC,L]
The second one would look like example.com/?filename to the user, whereas the first one would look like example.com/portfolio/filename.htm.
Hope that helps.
