.htaccess Won't Work Correctly

Question

So I have a Rewrite in my .htaccess that works correctly with what I originally planned.

RewriteEngine on
RewriteRule ^([^/]+)/?$ index.php?id=$1 [QSA]

I have index.php?id=4 going to /4/.

The Problem

If I try to go to another page though, it always brings me back to index.php. For example, I have a page called "Update.php". If I go to update.php, I'm redirected to index.php

Any suggestions?

Thanks in advance,

Answer 1

RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f #check if requested file not found
RewriteCond %{REQUEST_FILENAME} !-d #check if requested directory not found
RewriteRule ^([^/]+)/?$ index.php?id=$1 [QSA] #then apply the rule

The above rule first checks if requested URI not a real file and folder, then applying the rule, this prevents to redirect when opening existing file and folder.

Answer 2

Add this line

RewriteCond %{REQUEST_FILENAME} !-f

Above your rule

This only rewrites when the file doesn't exist
