rewrite redirect help needed

[dethfire]

Trying to redirect this format

archive/topic/t-59411_Nastase_RHIC_produces_black_holes.html

to this:

archive/index.php/t-59411.html

I can only find examples of what to do if they were querystrings.

thanks!!

The number is dynamic though and the keywords are too, I'm going to try this:

RewriteRule ^archive/topic/t-([0-9]+)([[a-zA-Z0-9_]+).html$ archive/index.php/t-$1.html [R=301,L]

Looks good! I would add one slash just to be sure

RewriteRule ^archive/topic/t-([0-9]+)([[a-zA-Z0-9_]+).html$ /archive/index.php/t-$1.html [R=301,L]

Just to be clear, but it might work fine without (my .htaccess is getting a bit rusty)

I got what I wanted mostly from this:

RewriteRule ^archive/topic/t-([0-9-]+)([[a-zA-Z0-9_]*).html$ archive/index.php/t-$1.html [R=301,L]
RewriteRule ^archive/topic/t-([0-9-]+)$ archive/index.php/t-$1.html [R=301,L]

RewriteRule ^archive/topic/([0-9-]+).html$ archive/index.php/t-$1.html [R=301,L]

RewriteRule ^archive/t-([0-9-]+)([[a-zA-Z0-9_]+).html$ archive/index.php/t-$1.html [R=301,L]
RewriteRule ^archive/t-([0-9]+)$ archive/index.php/t-$1.html [R=301,L]


I assume it's not very efficent. Is there a more compact way to do this?

There is, but it's highly unreadable and not any more efficient in terms of speed. I'd just stick with what you have now

I'll give it a go for funsies.

RewriteRule ^archive/(?:topic/)?(?:t-)?(\d+)[^/]*\.html$ /archive/index.php/t-$1.html [R=301,L]

RewriteRule ^archive/(?:topic/)?(?:t-)?(\d+)[^/]*\.html$ /archive/index.php/t-$1.html [R=301,L]

That misses two of the rules

RewriteRule ^archive/topic/t-([0-9-]+)([[a-zA-Z0-9_]*).html$ archive/index.php/t-$1.html [R=301,L]
RewriteRule ^archive/topic/t-([0-9-]+)$ archive/index.php/t-$1.html [R=301,L]

RewriteRule ^archive/topic/([0-9-]+).html$ archive/index.php/t-$1.html [R=301,L]

RewriteRule ^archive/t-([0-9-]+)([[a-zA-Z0-9_]+).html$ archive/index.php/t-$1.html [R=301,L]
RewriteRule ^archive/t-([0-9]+)$ archive/index.php/t-$1.html [R=301,L]

because they don't end in .html, so that should be an optional group as well.

Off Topic:

I never knew Apache 2 supported non-matching groups, good to know!

[Jeff Mott]

Oops. You're right.

If the extension is optional, then we may be able to get away with leaving off the end of the pattern altogether.

RewriteRule ^archive/(?:topic/)?(?:t-)?(\d+) /archive/index.php/t-$1.html [R=301,L]
