.htaccess RewriteCond %{REQUEST_FILENAME} !-d not working - php

Question

.htaccess code is,
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^p/([A-Za-z0-9-_]+)/?$ redirect.php?url=$1 [NC,L] #
RewriteRule ^[A-Za-z0-9-_]+/([A-Za-z0-9-_]+)/?$ product.php?seo_id=$1 [NC,L] #
RewriteRule ^([A-Za-z0-9-_]+)/?$ catalog.php?seo_id=$1 [NC,L] #
I'm trying to access http://example.com/directory/ which is already exist in server but i can't access it. There is no any error occuring but, if there is a request for already existant directory, rules after RewriteCond %{REQUEST_FILENAME} !-d should not be applied.
But in this case one of the 3 rules are applying.
RewriteCond %{REQUEST_FILENAME} !-d is seems not working.

Answer 1

RewriteCond only applies to the next RewriteRule, not to all of them. You should then duplicate them like so :
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^p/([A-Za-z0-9-_]+)/?$ redirect.php?url=$1 [NC,L] #
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^[A-Za-z0-9-_]+/([A-Za-z0-9-_]+)/?$ product.php?seo_id=$1 [NC,L] #
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([A-Za-z0-9-_]+)/?$ catalog.php?seo_id=$1 [NC,L] #
An alternative solution consists in using the S flag (skip) and invert the RewriteCond : Apache doc for S flag or examples (article in French, but the htaccess snippet don't need translation :) )
EDIT with another solution (not tested) :
# if it's a file or a folder
RewriteCond %{REQUEST_FILENAME} -d [OR]
RewriteCond %{REQUEST_FILENAME} -f
RewriteRule .* - [S=3] # then skip the next 3 rules
RewriteRule ^p/([A-Za-z0-9-_]+)/?$ redirect.php?url=$1 [NC,L]
RewriteRule ^[A-Za-z0-9-_]+/([A-Za-z0-9-_]+)/?$ product.php?seo_id=$1 [NC,L]
RewriteRule ^([A-Za-z0-9-_]+)/?$ catalog.php?seo_id=$1 [NC,L]
