Add trailing slash after removing .html extention

[Uber_]

My website is non www ,it has wordpress in subdirectory and some static webpages in the root and other subdirectory

1. i want to remove .html extention from the webpages in the root and
the others static webpages in subdirectory.
2. add slash at the end.
3. 301 redirect from non slash to url with slash.

so it should be

http://ghadaalsaman.com/articles.html to http://ghadaalsaman.com/articles/

and

http://ghadaalsaman.com/en/poem-list.html to http://ghadaalsaman.com/en/poem-list/

the below code

1. working with non slash at the end

**2. **redirect 301 url with slash to non

here's my .htaccess

<ifmodule mod_rewrite.c="">Options +FollowSymLinks -MultiViews

RewriteEngine On
RewriteBase /</ifmodule>

#removing trailing slash
RewriteCond %{REQUEST_FILENAME} !-d     
RewriteRule ^(.*)/$ $1 [R=301,L]

#www to non
RewriteCond %{HTTP_HOST} ^www.(([a-z0-9_]+.)?domain.com)$ [NC]
RewriteRule .? http://%1%{REQUEST_URI} [R=301,L]

#html
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^.]+)$ $1.html [NC,L]

#index redirect
RewriteCond %{THE_REQUEST} ^[A-Z]{3,9}\ /index.html\ HTTP/
RewriteRule ^index.html$ http://ghadaalsaman.com/ [R=301,L]
RewriteCond %{THE_REQUEST} .html
RewriteRule ^(.*).html$ /$1 [R=301,L]

PS everything is ok with the wordpress , the problems with static pages only.

Thanks in advanced

Can you please try the above but delete:

#removing trailing slash
RewriteCond %{REQUEST_FILENAME} !-d     
RewriteRule ^(.*)/$ $1 [R=301,L]

Let me know if that works.

Hi Uber_,

Typically this is handled is by adding the following to your .htaccess file:

RewriteCond %{REQUEST_FILENAME} !-f              <--looks like your version of this would also work fine.

RewriteCond %{REQUEST_URI} !index.php             <---This is very optional. If there are any .php files you don't want to be rewritten add their .endpath here.

RewriteCond %{REQUEST_URI} !(.*)/$                   <----Looks like you have this, which determines which url doesn't have a trailing slash.

RewriteRule ^(.*)$ http://ghadaalsaman.com.com/$1/ [L,R=301]    <----This would add a trailing slash and then redirect to the new URL.

Highly recommend you add the last line because both of your / and non / ending urls are populating (which could cause duplicate content issues). This will also help with allocating proper page authority.

Hope this helps,
B
