How to Make Custom Rewrite Rules in WordPress

You may notice that any custom rewrite rules you make for specific folder paths under your site’s domain will simply produce 404 errors on your WordPress blog.

To fix this, try the following:

1. Open your .htaccess file. The code for WordPress will look like this:

   # BEGIN WordPress
   <IfModule mod_rewrite.c>
   RewriteEngine On
   RewriteBase /
   RewriteCond %{REQUEST_FILENAME} !-f
   RewriteCond %{REQUEST_FILENAME} !-d
   RewriteRule . /index.php [L]
   </IfModule>
   # END WordPress

2. List paths which should not obey WordPress rewrites in the RewriteCond %{REQUEST_URI} !^/(path1|path2|path3) [NC]. Here is the fix in action:

   # BEGIN WordPress
   <IfModule mod_rewrite.c>
   RewriteEngine On
   RewriteBase /
   RewriteCond %{REQUEST_FILENAME} !-f
   RewriteCond %{REQUEST_FILENAME} !-d
   
   RewriteCond %{REQUEST_URI} !^/(abc|xxx|events/go-to-town) [NC]
   
   RewriteRule . /index.php [L]
   
   RewriteRule ^abc/$ "http://wordpress.com/" [R=301,L]
   RewriteRule ^xxx/$ "http://support.hostgator.com/" [R=301,L]
   RewriteRule ^events/go-to-town/$ "http://secure.hostgator.com/~affiliat/cgi-bin/affiliates/clickthru.cgi?id=whatever" [R=301,L]
   
   </IfModule>
   # END WordPress

   Note: This code works for WordPress blogs hosted on their own domain (primary, addon, subdomain); however, the code must be changed to work with a blog installed in a subfolder without its own domain.
   
   To make this work with a www.mydomain.com/blog type address, you just need to tweak one line:
   
   RewriteCond %{REQUEST_URI} !^/(blog/abc|blog/xxx|blog/events/go-to-town) [NC]
   
   The rewrite rules remain the same.

3. Then you can add your custom rewrite rules above the </IfModule>.

Warning! Each line of code in the .htaccess file must have its own new line in the file. Do not allow a long line to break and continue on a new line or your code will have unexpected behavior. For example:

RewriteRule ^events/go-to-town$ "http://secure.hostgator.com/~affiliat/cgi-bin/affiliates/clickthru.cgi?id=whatever" [R=301,L]

This should all be one line.
