Mod Rewrite and rewriteCond

jperezmt · 05-16-2008, 03:28 PM

I'm trying to make friendly urls for my site but I'm having some issues. I looked at a bunch of tutorials for mod rewrite and .htaccess and I got far enough where it works but I'm having trouble getting rid of the old links.

The address is www.thesite.com/blog.php?id=34

I got the mod rewrite to display it as

www.thesite.com/blog34/PHP/TITLEOFBLOG.htm

Code:

Options +FollowSymLinks
RewriteEngine On
RewriteRule ^blog([0-9A-Za-z]+)/([0-9A-Za-z]+)/([0-9A-Za-z]+).htm$  blog.php?id=$1&category=$2&title=$3 [L]

But I'm trying to eleminate duplicate content and get redirect the blog.php?id=34 to the new URL

Here is my code

Code:

RewriteCond %{QUERY_STRING} ^id=([0-9]+)
RewriteRule ^blog\.php /blog%1/%2/%3.htm? [R=301,L]

So the %2 and %3 don't exist in the redirect so I'm getting
www.thesite.com/blog34//.htm

How can I redirect the old URLS with only the ID to the new ones that list the category and title?

Also, is it possible to just get rid of the ID number so I can have the same content display with just text?

Thanks!!!!

well. You can't do it using mod_rewrite, because you do not have page titles in it.

the simplest way - do redirect directly from php. Like such one

Code:

$page = mysql_fetch_assoc(mysql_query("SELECT * FROM pages WHERE id=".$_GET["id]);
$new_location = $page["title"]."/".$page["category"].".html";
header ('HTTP/1.1 301 Moved Permanently');
header("Location: ".$new_location);
die();

I just tried that and I keep getting this error:

Warning: Cannot modify header information - headers already sent by (...) in ...on line 11
