Investigating the presence of a file within the superior directory with RewriteCond

I am attempting to enhance this .htaccess file in order to redirect all requests to a script when the requested file or directory is non-existent. However, I want to refactor it so that it checks for the existence of the file in the parent folder.
Currently, my .htaccess looks like this:

RewriteEngine on

# check if requested file or directory exists
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

# map requests to contentpage.php and append it as a query string
RewriteRule ^(.*)/(.*)$ contentpage.php?url=$2&lang=$1

At present, this .htaccess successfully redirects
en/products.php -> contentpage.php?url=products.php&lang=en only if there is no products.php file within the child directory /en/ (and since the physical directory /en/ does not exist, the RewriteCond fails to filter cases where I have a file named products.php in the parent directory).

I need to modify it so that it checks for the file's existence in the top-level directory where my files are located. The redirection should only occur for language directories such as /en, /es, /de, /pt, etc.

Does anyone have any ideas on how to solve this issue? Thank you.

Answer №1

If you want to apply specific rules for your website, you can create an htaccess file in the root directory. This allows you to customize the behavior of your URLs.

 /parent
     /en
     /es 
     /de

Whether you access the parent path or any of the child paths:

  • /parent/products.php
  • /parent/en/products.php

The directives written in the /parent/.htaccess file will be applied.
So, you have the freedom to define your own set of rules:

# Check if the requested file does not exist in the child directory.
# If it doesn't, then check if it also does not exist in the parent directory.
RewriteCond /parent/$1/$2 !-f
RewriteCond /parent/$2 !-f
RewriteRule ^/parent/(es|en|fr|de)/(.*)$ contentpage.php?url=$2&lang=$1

# Check if the requested file does not exist in the parent directory.
RewriteCond /parent/$1 !-f
RewriteRule ^/parent/(.*)$ contentpage.php?url=$2&lang=$1
