Question

htaccess redirects for seo friendly urls (infinite loop problem)

Asked by: marklye

Hi there

Im trying to redirect my current URL structure to friendly URLs.  I want to redirect the following scenarios:

example.com/test.php >> example.com/testing
example.com/test.php?id=1 >> example.com/testing/1
example.com/test.php?id=sometext >> example.com/testing/sometext
example.com/test.php?id=sometext&id2=moretext >> example.com/testing/sometext/moretext

I can get it to work to use example.com/test.php if a user enters example.com/testing, however I get inifite loop problems to redirect the old url to the new friendly url.

Thanks a million.  If you can supply htaccess code for above examples I'll be up and running

Cheers
Mark

HI

For starters:

RewriteEngine on
#For: example.com/test.php >> example.com/testing
RewriteCond %{REQUEST_URI} ^/test.php$
RewriteCond %{QUERY_STRING} !^id=
RewriteRule .* /testing [R=301,L]
# For: example.com/test.php?id=sometext >> example.com/testing/sometext
RewriteCond %{REQUEST_URI} ^/test.php$
RewriteCond %{QUERY_STRING} ^id=([a-zA-Z0-9_-]+)$
RewriteRule .* /testing/%1  [R=301,L]
# For: example.com/test.php?id=sometext&id2=moretext >> example.com/testing/sometext/moretext
RewriteCond %{REQUEST_URI} ^/test.php$
RewriteCond %{QUERY_STRING} ^id=([a-zA-Z0-9_-]+)\&id2=([a-zA-Z0-9_-]+)$
RewriteRule .* /testing/%1/%2  [R=301,L]

Hi arober11,

Thanks for your reply.  I have tried your example and cant get it to work.  For eg

For example.com/test.php?id=sometext

RewriteCond %{REQUEST_URI} ^/test.php$
RewriteCond %{QUERY_STRING} !^a=sometext
RewriteRule .* /sometext [R=301,L]

If I type example.com/test.php?id=sometext in to the browser it does not redirect to /sometext.  And if I type example.com/sometext I get a 404

I am probably doing something wrong here.   Thanks again for your help!

Cheers
Mark

Hi

In you example http://example.com/test.php?id=sometext

change your:

RewriteCond %{QUERY_STRING} !^a=sometext
To:
RewriteCond %{QUERY_STRING} !^id=sometext

as the variable in your example url is "id="  not "a="

 

by: marklyePosted on 2009-08-02 at 05:57:44ID: 24998687

Hi there

Apologies, my fault.  The variable is actually a, not id for the site.  I am actually entering:

http://example.com/test.php?a=sometext

Sorry about the mistake.  Any ideas?   Just to add, I am running this from a subdirectory which is a test area for the site.  Would this cause any problems?

Thanks
Mark

Are the re-write rules in the httpd.conf or an .htaccess files?

If it's a .htaccess file then they need to be in the root file, the one in the DocumentRroot directory else you need to change them e.g. for URL:  http://example.com/your-sub-directory/test.php?a=sometext
You'll want:
RewriteCond %{REQUEST_URI} ^/sour-sub-directory/test.php$
RewriteCond %{QUERY_STRING} !^a=sometext
RewriteRule .* /sometext [R=301,L]

 

by: marklyePosted on 2009-08-02 at 08:06:46ID: 24999039

Hi there

Im using a htaccess file saved in the directory root of my test structure (example.com/your-sub-directory/).  I have added the full structure to the paths like:

RewriteEngine On
RewriteCond %{REQUEST_URI} ^/your-sub-directory/test.php$
RewriteCond %{QUERY_STRING} !^a=sometext
RewriteRule .* /your-sub-directory/sometext [R=301,L]

Replacing your-sub-directory with my correct test site directory name.  If I browse to:

example.com/your-sub-directory/test.php

It redirects to:

example.com/your-sub-directory/sometext

However 404s.   If i browse:

example.com/your-sub-directory/test.php?a=buy

It does not redirect, but the page displays, and finally if I browse to:

example.com/your-sub-directory/sometext

It 404s.   My htaccess only has the code in above, and none of your other examples at the moment

Thanks
Mark

Expected, you need to include / adapt the all 3 re-write rules from my original post, in you .htaccess file, before all variants of your URL work.

Your rule above only covers part of your:
example.com/test.php >> example.com/testing
requiremet,

The following tweak would complete that one requirement (post your specification change).
...
RewriteCond %{QUERY_STRING} !^a=
RewriteRule .* /your-sub-directory/sometext.html [R=301,L]

Also assuming  you have a  /your-sub-directory/sometext.html  file, if not create one
<HTML>
<H2>This is a test<H2>
Testing 123....
</HTML>

Are just realized you are after the reverse of that you arrows indicated e.g.

So rather than entering: "example.com/test.php"  and being redirected (>>) to "example.com/testing"

You want to enter "example.com/testing" and being redirected (>>) to"example.com/test.php"

in which case the following may do the trick:

RewriteEngine on
RewriteBase /
RewriteRule testing$                  /test.php              [L]
RewriteRule testing/([^/]+)$          /test.php?id=$1        [L]
RewriteRule testing/([^/]+)/([^/]+)$  /test.php?id=$1&id2=$2 [L]
