Add Trailing Slash .htaccess

Question

I'm trying to get the following effect (using this local file http://localhost/[company_name]/[project_name]/.htaccess):

http://localhost/[company_name]/[project_name]/page-1 (adds slash)
http://localhost/[company_name]/[project_name]/page-1/ (does nothing)
http://localhost/[company_name]/[project_name]/page-1/subpage-1 (adds slash)
http://www.example.com/page-1 (adds slash)<br />
http://www.example.com/page-1/ (does nothing)
etc.

The thing I want to accomplish is that this .htaccess doesn't need the path http://localhost/[company_name]/[project_name]/ anymore so that I don't have to edit this each time it's been uploaded.

RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*[^/])$ /$1/ [L,R=301]

I found the code above here: Add Trailing Slash to URLs, but it only makes it possible to use the HOST dynamically and discards the path. Does someone a solution to accomplish this effect?

Answer 1

RewriteCond %{REQUEST_URI} !(/$|\.) 
RewriteRule (.*) %{REQUEST_URI}/ [R=301,L] 

Answer 2

Please add below lines top of .htaccess file

RewriteEngine on
#Add Trailing slash for end of the URL
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*[^/])$ /$1/ [L,R]
