Remove or add trailing slash from CakePHP 2.x on Apache using .htaccess - apache

Question

I am trying to enforce the removal or add of trailing slashes to my CakePHP 2.x app using the following inside the .htaccess located at /app/webroot.
#<IfModule mod_rewrite.c>
# RewriteEngine On
# RewriteCond %{REQUEST_FILENAME} !-d
# RewriteCond %{REQUEST_FILENAME} !-f
# RewriteRule ^ index.php [L]
#</IfModule>
<IfModule mod_rewrite.c>
# Add trailing slash
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} !(\.[a-zA-Z0-9]{1,5}|)$
RewriteRule ^(.*)$ http://www.domain.com/$1 [L,R=301]
</IfModule>
or the following for add the trailing slash.
RewriteCond %{REQUEST_URI} !(/$|\.)
RewriteRule (.*) %{REQUEST_URI}/ [R=301,L]
But I don't want to enforce the domain as it could be running locally or inside a subfolder. How do I fix this? All the docs I've read online seem to enforce the FULL url of the app.
In fact even if I use the FULL url it still doesn't work. Has anyone managed to get this working with CakePHP? Seems you MUST run it through the index.php file
To clarify I'm looking for a solution for ADDING and REMOVING trailing slashes in CakePHP without having to hardcode the url into the .htaccess file.

Answer 1

This is usually not a complicated thing.
What about this ?
<IfModule mod_rewrite.c>
RewriteEngine On
# if this is an existing folder/file then leave
RewriteCond %{REQUEST_FILENAME} -d [OR]
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule . - [L]
# if trailing slash then redirect to url without trailing slash
RewriteRule ^/?(.+)/$ /$1 [R=301,L]
# internal rewrite to controller/dispatcher index.php
RewriteRule ^.*$ /index.php [L,QSA]
</IfModule>
If this one is not working, well this could be a problem on your side.
Did you already use mod_rewrite before ? Is it enabled ?
EDIT: if your website is not in root folder (DOCUMENT_ROOT) you have 2 options. You could put your htaccess in application folder or in root folder.
I suggest you to put your htaccess in your application folder (dedicated for your website only). Otherwise, the code would not be exactly the same. Here's the code in this case:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /application/
# if this is an existing folder/file then leave
RewriteCond %{REQUEST_FILENAME} -d [OR]
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule . - [L]
# if trailing slash then redirect to url without trailing slash
RewriteRule ^/?(.+)/$ $1 [R=301,L]
# internal rewrite to controller/dispatcher index.php
RewriteRule ^.*$ index.php [L,QSA]
</IfModule>
Your second question:
Also what would be the code for ENFORCING a trailing slash?
You could handle that with this code (only one line changed)
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /application/
# if this is an existing folder/file then leave
RewriteCond %{REQUEST_FILENAME} -d [OR]
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule . - [L]
# if no trailing slash then redirect to url with trailing slash
RewriteRule ^/?(.+)([^/])$ $1$2/ [R=301,L]
# internal rewrite to controller/dispatcher index.php
RewriteRule ^.*$ index.php [L,QSA]
</IfModule>

Answer 2

Try this :
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} !(\.[a-zA-Z0-9]{1,5}|)$
RewriteRule ^(.*)$ http://%{HTTP_HOST}/$1 [L,R=301]
</IfModule>

Answer 3

Try this (bakery):
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !(\.[a-zA-Z0-9]{1,5}|/)$
#RewriteRule ^(.*)$ http://%{HTTP_HOST}/$1/ [L,R=301]
RewriteRule ^(.*)$ http://%{HTTP_HOST}/$1/ [L,R=301]
If you want to do it for SEO you always have an option to use canonical links and stop bother about redirects:
<link rel="canonical" href="/your_controller/action/"/>
