Htaccess to rewrite URL with two parameters

I want to rewrite this type of URL

https://mywebsite.com/content/page.html?id=12&title=my-page-title

to

https://mywebsite.com/12/my-page-title.html

Using generateit.net/mod-rewrite/ I got the following rule:

RewriteEngine On
RewriteRule ^([^/]*)/([^/]*)\.html$ /content/page.html?id=$1&title=$2 [L]

But when tested on htaccess.madewithlove.com/ I get this:

The new url is https://mywebsite.com/content/page.html?id=content&title=page

The term "rewrite" refers to a process which has as its input the URL requested by your website visitor, and as its output the URL passed to your CMS to produce the requested page.

The service at https://www.generateit.net/mod-rewrite/ generates a rewrite rule allowing your pages to be reached through URLs of the form

https://mywebsite.com/12/my-page-title.html

even though the underlying system expects URLs of the form

https://mywebsite.com/content/page.html?id=12&title=my-page-title

It does that by rewriting the former to the latter, which is exactly what the rewrite rule quoted in your question does.

To test that with the service at https://htaccess.madewithlove.com/, you have to enter

https://mywebsite.com/12/my-page-title.html

in the field labeled "Fill in the url that you're applying the rules to". It would seem that you entered the rewrite result there instead.

Thank you RavinderSingh13, from StackOverflow, for helping me with the code.

To turn

https://mywebsite.com/pages/article.html?id=1&title=Title-Goes-Here

into

https://mywebsite.com/pages/article/1/Title-Goes-Here

Use

RewriteEngine ON
##External redirect in browser rules here....
RewriteCond %{ENV:REDIRECT_STATUS} ^$
RewriteCond %{THE_REQUEST} \s/([^/]*)/([^.]*)\.html\?id=([^&]*)&title=(\S+)\s [NC]
RewriteRule ^ /%1/%2/%3/%4? [R=301,L]

##Internal rewrite to html file rules here....
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]*)/([^/]*)/([^/]*)/([^/]*)/?$  $1/$2.html?id=$3&title=$4 [QSA,NC,L]

Also, after head element, I had to put:

<base href="/" />

If you have atricle.html in the main folder, with htaccess you can also use:

RewriteEngine on
RewriteRule ^article/([0-9]+)/([0-9a-zA-Z_-]+)$ article.html?id=$1&title=$2 [NC,L]
