Ignore a particular folder in htaccess - php

Question

I am facing issues regarding my .htaccess. The .htaccess works, but it causes a problem with the admin folder. Would it be possible to exclude that specific folder from this .htaccess? Here is my .htaccess. It is outside the admin folder.
Options -MultiViews
ErrorDocument 404 http://localhost/blo-prt/err.php
RewriteEngine On
RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s([^.]+)\.php [NC]
RewriteRule ^ %1 [R=301,L]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^(.*?)/?$ $1.php [L,QSA]
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^blo/([^/\.]+)?$ blo-det.php?postlist=$1 [L,QSA]
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^category/blo/([^/\.]+)?$ blo-prior.php?bloglist=$1 [L,QSA]
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^tep/([^/\.]+)?$ temp-det.php?telist=$1 [L,QSA]
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^category/tep/([^/\.]+)?$ temp-of-prior.php?tlist=$1 [L,QSA]

Answer 1

You should add this to your RewriteConds:
# if request is not for the /admin/
RewriteCond %{REQUEST_URI} !^/admin/ [NC]
Personally, I use this code to remove the .php extension:
# enable url rewriting
RewriteEngine On
# remove .php
RewriteCond %{THE_REQUEST} /([^.]+)\.php [NC]
RewriteRule ^ /%1 [NC,L,R]
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^ %{REQUEST_URI}.php [NC,L]
Also, you should only type RewriteEngineOn just once at the top of the file.
