htaccess doesn't work as expected - php

Question

I have an htaccess rewrite URL as below:
RewriteEngine On
RewriteCond %{HTTP_HOST} ^www.mywebsite.com$ [NC]
RewriteRule ^(.*)$ http://mywebsite.com/$1 [R=301,L]
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^my-page\.html$ /my-page.php [L]
RewriteRule ^my-page/([^/]*)\.html$ /level1.php?num=$1 [L]
RewriteRule ^my-page/([^/]*)/([^/]*)\.html$ /level2.php?level1=$1&level2=$2 [L]
RewriteRule ^([^/]*)\.html$ /level3.php?level3=$1 [L]
These rules above rewrite URLs from mywebsite.com/my-page.php to mywebsite.com/my-page.html.
Now, what I want to achieve is mywebsite.com/my-page/ to be redirected to mywebsite.com/my-page.php (which in turn rewrites to mywebsite.com/my-page.html).
What I have tried, I created a directory "my-page" and tried to redirect requests from mywebsite.com/my-page/ to /my-page.html.
I don't know what went wrong. I can see in the network tab that a request is made to /my-page/ and gets rewritten to mywebsite.com/my-page.htmlmy-page/, which gives a 302 Status ☹
Please help! Thank you.

Answer 1

You can try use RedirectMatch to achieve this.
Redirect to my-page.php:
RedirectMatch 301 ^/my-page/ http://mywebsite.com/my-page.php
or straight away to my-page.html if this is your goal:
RedirectMatch 301 ^/my-page/ http://mywebsite.com/my-page.html
or, what will be best - change the code responsible for mywebsite.com/my-page.htmlmy-page/, but I can't see it in question you have asked :)

Answer 2

Please give the following a try. Brief descriptions are found in the comments for each section.
RewriteEngine On
# Trim www.
RewriteCond %{HTTP_HOST} ^www\.mywebsite\.com$ [NC]
RewriteRule ^(.*)$ http://mywebsite.com/$1 [R=301,L]
RewriteBase /
# Redirect /my-page[/] to /my-page.html
# >> Note: change 302 to 301 to make permanent
RewriteRule ^my-page/?$ my-page.html [R=302,L]
# Allow existing files and directories
# Recommended to comment out the first line
RewriteCond %{REQUEST_FILENAME} -d
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule ^ - [L]
# Rewrite *.html to respective page
RewriteRule ^my-page.html$ my-page.php [L]
RewriteRule ^my-page/([^/]*).html$ level1.php?num=$1 [L]
RewriteRule ^my-page/([^/]*)/([^/]*).html$ level2.php?level1=$1&level2=$2 [L]
RewriteRule ^([^/]*).html$ level3.php?level3=$1 [L]
The important part here is that you do the required redirect before any other rewrites (except the www. removal).
Also, you previously had the two conditions which stated that if the request was not for a file or directory, then proceed with the next rule, but that wouldn't have accounted for the last two rules. As such, this version tells Apache to stop everything if the request is for an existing file or directory. I would recommend, for security purposes, that you comment out the line that checks for existing directories.
