Trying to remove path, file extension and, if present, a certain query parameter

I'm fairly new to .htaccess, but have gotten close to what I need, but am now stuck.

Input: https://www.example.com/p/mypage.html

Output: https://www.example.com/mypage

This is achieved with the following:

# Static pages: Remove /p from path and remove .html
RewriteRule ^p(/.*?)(?:\.html)?$ $1 [R=301,L]
# All other posts just remove .html
RewriteCond %{REQUEST_URI} ^/(.+)\.html?$ [NC]
RewriteRule ^ /%1 [L,R=301]

However, very often there is a query parameter m=1 that needs removed IF IT IS PRESENT

I need that query parameter removed for both static pages AND other posts in the above RewriteRules. Note that there very often may be other query parameters also present but that I do not want those to be removed.

Example 1:

Input: https://www.example.com/p/mypage.html?param1=a&m=1&param2=b

DESIRED output: https://www.example.com/mypage?param1=a&param2=b

Example 2:

Input: https://www.example.com/2019/12/mypage.html?param1=a&m=1&param2=b

DESIRED output: https://www.example.com/2019/12/mypage?param1=a&param2=b

In both of the above examples, all of the following are removed:

  • /p if present

  • .html if present

  • m=1 if present (sometimes it may be the only query parameter so that also needs taken into account)

(By the way, the above three bullets will be useful for anyone moving a site over from Blogger / Blogspot to Wordpress, as they represent the differences in how the paths and pages are handled)

Very much appreciate any help with the m=1 being removed if present.

Could you please try following, written as per shown samples. Also please make sure you clear your browser cache before testing your URLs.

RewriteEngine ON
# Static pages: Remove /p from path and remove .html
RewriteCond %{QUERY_STRING} ^$
RewriteRule ^p(/.*?)(?:\.html)?$ $1 [R=301,L]

# All other posts just remove .html
RewriteCond %{QUERY_STRING} ^$
RewriteCond %{REQUEST_URI} ^/(.+)\.html?$ [NC]
RewriteRule ^ %1 [L,R=301]

#Check if URI has .html with query string present in it.
RewriteCond %{THE_REQUEST} \s(?:/p)?/(.*)\.html\?(.*)(?:[&?])m=1(.*)\s [NC]
RewriteRule ^ %1?%2%3 [R=301,L]

2nd solution: In case you are looking for specifically only param1 and param2 parameters then try following.

RewriteEngine ON
# Static pages: Remove /p from path and remove .html
RewriteCond %{QUERY_STRING} ^$
RewriteRule ^p(/.*?)(?:\.html)?$ $1 [R=301,L]

# All other posts just remove .html
RewriteCond %{QUERY_STRING} ^$
RewriteCond %{REQUEST_URI} ^/(.+)\.html?$ [NC]
RewriteRule ^ %1 [L,R=301]

#Check if URI has .html with query string present in it.
RewriteCond %{THE_REQUEST} \s(?:/p)?/(.*)\.html\?(param1=[^&]*)(?:[?&])m=1(param2=[^\s]*)\s [NC]
RewriteRule ^ %1?%2%3 [R=301,L]

You may use this rule to remove a query parameter if present and remove /p or .html as well.

Here is your complete .htaccess:

RewriteEngine On

RewriteCond %{THE_REQUEST} \?(.*&)?m=1&?(\S*)\sHTTP [NC]
RewriteRule ^(?:p/)?(.+)(?:\.html)?$ /$1?%1%2 [R=301,NE,NC,L]

# Static pages: Remove /p from path and remove .html
RewriteRule ^p(/.*?)(?:\.html)?$ $1 [R=301,L,NC,NE]

# All other posts just remove .html
RewriteRule ^(.+)\.html$ /$1 [L,R=301,NC,NE]

You can use the following rule to remove m=1 query perameter from your URLs.

RewriteEngine on
RewriteCond %{QUERY_STRING} (.*?)&?(?:\bm=1)(.*)$
RewriteRule ^ %{REQUEST_URI}?%1%2 [R,L]
