htaccess - Need help writing the correct rule - php

Question

I'm using SimpleMVCFramework
All my routes are working fine, based on the default htaccess file:
Options -Indexes
<IfModule mod_rewrite.c>
Options -Indexes
RewriteEngine On
RewriteBase /mpl/servicos/smvcf/
# Force to exclude the trailing slash
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} (.*)/$
RewriteRule ^(.+)/$ $1 [R=307,L]
# Allow any files or directories that exist to be displayed directly
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?$1 [QSA,L]
</IfModule>
I have a route that expects an id:
http://localhost/mpl/servicos/smvcf/detalhe/37343
But I need the URL the user sees to be friendly as:
http://localhost/mpl/servicos/smvcf/mercedes_benz-a-a_220_cdi_auto-37343.html
I thought something like this would work, but I get a 404:
RewriteRule ([^/]+)-([^/]+)-([^/]+)-([^/]+).html detalhe/$4
Please help.

Answer 1

The user sees the pretty url, but you are not interested in what the seo-title is. What you are interested in is the number that is hidden in it. As the number is in the very back of the pretty url, let's just match on that:
RewriteRule ^[^/]+-([0-9]+)\.html detalhe/$1 [L]

If you are trying to use another rewrite that will not be routed through the default MVC route index.php then you need to make sure you place your new rewrite before those rules. Also that folder you are redirecting to will need to have a index PHP file to do something as well.
Options -Indexes
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /mpl/servicos/smvcf/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.+)-([0-9]+)\.html detalhe/$2 [L]
# Force to exclude the trailing slash
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} (.*)/$
RewriteRule ^(.+)/$ $1 [R=307,L]
# Allow any files or directories that exist to be displayed directly
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?$1 [QSA,L]
</IfModule>
