Htaccess redirect seems not working with php file extension to seo friendly (no extension) url-CodePudding

One of my website's old URL structures is like this:

    https://example.com/login.php
    or, 
    https://example.com/login.php?redirect=https://example.com
    or,
    https://example.com/register.php

after rebuilding the URLs, the URLs look like this:

    https://example.com/login
    or, 
    https://example.com/login?redirect=https://example.com
    or,
    https://example.com/register

Now when the user/visitor uses the old URL https://example.com/login.php, I want to redirect to the https://example.com/login page. How can I do it?

FYI, currently, my .htaccess file has the following content:

AddDefaultCharset UTF-8

ErrorDocument 404 /error-404/

##
Options  FollowSymlinks -MultiViews
RewriteEngine on
RewriteBase /

## Allow a few SEO Files direct access.
RewriteRule ^robots.txt?$ robots.txt [L]
RewriteRule ^ads.txt?$ ads.txt [L]
RewriteRule ^sellers.json?$ sellers.json [L]


## Avoid rewriting rules for the admin section
RewriteRule ^(admin|resources)($|/) - [L]

## Set Ajax Request File
RewriteRule ^kahuk-ajax.php?$ kahuk-ajax.php? [L,QSA]

## Set controller with id
RewriteRule ^([^/] )/([0-9] )/?$ index.php?con=$1&id=$2 [L,QSA]

## Set controller with slug
RewriteRule ^([^/] )/([^/] )/?$ index.php?con=$1&slug=$2 [L,QSA]

## For paging
RewriteRule ^([^/] )/page/([0-9] )/?$ index.php?con=$1&page=$2 [L,QSA]
RewriteRule ^([^/] )/([^/] )/page/([0-9] )/?$ index.php?con=$1&slug=$2&page=$3 [L,QSA]

## Set controller for only one parameter
RewriteRule ^page/([^/] )/?$ index.php?con=page&slug=$1 [L,QSA]
RewriteRule ^([^/] )/?$ index.php?con=$1 [L,QSA]

## Set home page
RewriteRule ^/?$ index.php?con=home [L]

CodePudding user response：

You can insert this rule just below RewriteBase / line to remove .php extension:

# To externally redirect /afile.php to /afile
RewriteCond %{THE_REQUEST} \s/ (. ?)\.php[\s?] [NC]
RewriteRule !^admin/ /%1 [R=301,NE,L,NC]
