mod_rewrite faq

Hi

I need to use mod_rewrite to change my links from
http://www.aophotography.com/photo_g...lbum=11&pos=15
to something a little more Google friendly.

Does a step by step guide exist anywhere on how to use mod_rewrite for
a case like this? I found
http://httpd.apache.org/docs/mod/mod_rewrite.html but it does seems to
tell you how the thing works rather than just how to use it.

Regards

Anthony

On the bottom of that page there is a link to the Rewriting Guide:
http://httpd.apache.org/docs/misc/rewriteguide.html

You can also find a variety of guides via google:

First figure out what you want the virtual URI (the one people see) to
look like. How about this:

http://www.aophotography.com/photo_g...11_pos_15.html

To map this add two lines to your .htaccess file in photo_gallery/ :

RewriteEngine on
RewriteRule ^album_(.*)_pos_(.*)\.html /photo_gallery/displayimage.php?album=$1&pos=$2 [T=application/x-httpd-php,L]

Presumably you have no other real pages in photo_gallery that start
with "album" - then you should be fine.

Thanks for taking the time to reply. I will try that out.

Thank you. Your post gave me a good starting point. The only problem
is it does not quite work. I get a "The selected album/picture does
not exist !" which you will see if you follow the link
http://www.aophotography.com/photo_g...11_pos_15.html

After a little reading i realized that the php photo gallery is still
going to show dynamic links from it's pages. I some how need a system
that goes through a page before it is displayed and changes the links
to static ones. It is beginning to sound very complicated! Any help
much appreciated.

I typed this from my own .htaccess file for something very similar and
mine does work. I did forget one thing (doh regular expressions!) that
might break it. Add a "$" after the ".html" - so it's this:

RewriteRule ^album_(.*)_pos_(.*)\.html$ /photo_gallery/displayimage.php?album=$1&pos=$2 [T=application/x-httpd-php,L]

All you really need is a php script to generate every instance of your
photo gallery and then spit out the links HTML-style. A couple of
foreach-loops perhaps? Then put those links into a file Google will
crawl, to point it to each instance of the photo album.

One quick solution to this would be to use auto_prepend_file and
auto_append_file along with regex and output buffering.

in .htaccess (put in the photo gallery directory):
--------------------------------------------------
php_value auto_prepend_file /path/to/my/prependfile.php
php_value auto_append_file /path/to/my/appendfile.php

prependfile.php:
----------------
<?php ob_start() ?>

appendfile.php:
---------------
<?php
$contents=ob_get_contents();
ob_end_clean();

// here we have the contents of the output. Now, let's rewrite
// our URLS using regex.
echo preg_replace(
'/displayimage.php\?album=([0-9]*)&pos=([0-9]*)/i',
"album_$1_pos_$2.html",$content
);
?>

This is just off the top of my head, so there may be a couple bugs since
I didn't test it, but it should steer you in the right direction. Hope
it helps!

Could some one please tell me why this does not work?

I followed Mr. no_one's instructions exactly.

Thanks

Please post your .htaccess file so we can review it.
