Link rewriting

Do either of those URLs work directly? I mean when you type them into your browser.

Try moving this line

RewriteRule ^tag/(.*)$ ?tdo_tag=$1 [L]

To be above this line

# BEGIN WordPress

Not sure if that will, could, or should do what you think it will though. Also you may want to remove the [L] from that line.

After I read what I’d written, I realized that what I meant to say was add these lines above your # BEGIN WordPress like so

# Tag rewrite
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^category/(.*)/\?tdo_tag=(.*) http://site-name/tag/$2 [L]
</IfModule>

# BEGIN WordPress

Don’t bother copying those lines, it won’t work. 🙂

There may be a way to do it with mod_rewrite but it’s really search and replace on the URL that you want. My mod_rewrite is good, but not that good.

So use a plugin instead. I got the idea and code from this web site.

In wp-content/plugins create a file called tdo-tag-replace.php and paste in these lines.

<?php
/*
Plugin Name: TDO tag rewrite
*/

add_action( 'template_redirect', 'tdo_tag_rewrite' );
function tdo_tag_rewrite() {
   if ( strpos( $_SERVER['REQUEST_URI'], '?tdo_tag=' ) ) {
      wp_redirect( str_replace( '?tdo_tag=' , '/tag/' , $_SERVER['REQUEST_URI'] ) );
      exit();
   }
}

That should do it. It’s quick and dirty but it works. I have a feeling that $_SERVER['REQUEST_URI'] needs to be sanitized, and using $_SERVER['REQUEST_URI'] makes me itch, but that worked for me.
