.htaccess rules being overriden - php

Question

I am currently having an issue with a website I am working on. I am forwarding one URL to another URL.
In my root folder, I have the following code:
RewriteEngine On
RewriteCond %{HTTP_HOST} ^www.domaina.com
RewriteRule ^(.*) http://www.domainb.com/$1 [R=301,L]
It's redirecting traffic as it is supposed to, except in one directory on the website > /shop
In the /shop directory, there is also an .htaccess file and it seems to be cancelling out what I have set in the root. Here are the contents of the .htaccess in the /shop directory:
RewriteEngine On
RewriteBase /shop/
RewriteRule ^enclosures-enclosure-guidelines-c-229_675.html$
/resources#nema-guidelines [L,R=301,NE]
#RewriteRule ^category/(.*)$ index.php?$cPath=$2
RewriteRule ^mc/(.*)$ mc.php?keywords=$1
RewriteRule ^(.*)-c-(.*)-p-(.*)$ product_info.php?cPath=$2&products_id=$3&%{QUERY_STRING}
RewriteRule ^(.*)-p-(.*)$ product_info.php?products_id=$2&%{QUERY_STRING}
RewriteRule ^(.*)-c-(.*)$ index.php?cPath=$2&%{QUERY_STRING}
RewriteRule ^(.*)-c2-(.*)$ index2.php?cPath=$2&%{QUERY_STRING}
RewriteRule ^(.*)-c-(.*)-p-(.*).html$ product_info.php?cPath=$2&products_id=$3&%{QUERY_STRING}
RewriteRule ^(.*)-p-(.*).html$ product_info.php?products_id=$2&%{QUERY_STRING}
RewriteRule ^(.*)-c-(.*).html$ index.php?cPath=$2&%{QUERY_STRING}
RewriteRule ^(.*)-m-(.*).html$ index.php?manufacturers_id=$2&%{QUERY_STRING}
RewriteRule ^(.*)-pi-(.*).html$ popup_image.php?pID=$2&%{QUERY_STRING}
RewriteRule ^(.*)-t-(.*).html$ articles.php?tPath=$2&%{QUERY_STRING}
RewriteRule ^(.*)-a-(.*).html$ article_info.php?articles_id=$2&%{QUERY_STRING}
RewriteRule ^(.*)-pr-(.*).html$ product_reviews.php?products_id=$2&%{QUERY_STRING}
RewriteRule ^(.*)-pri-(.*).html$ product_reviews_info.php?products_id=$2&%{QUERY_STRING}
RewriteRule ^(.*)-i-(.*).html$ information.php?info_id=$2&%{QUERY_STRING}
RewriteRule ^(.*)-links-(.*).html$ links.php?lPath=$2&%{QUERY_STRING}
Any help would be appreciated.

Answer 1

it seems to be cancelling out what I have set in the root"
That's how .htaccess files work. From the docs:
The configuration directives found in a .htaccess file are applied to
the directory in which the .htaccess file is found, and to all
subdirectories thereof. However, it is important to also remember that
there may have been .htaccess files in directories higher up.
Directives are applied in the order that they are found. Therefore, a
.htaccess file in a particular directory may override directives found
in .htaccess files found higher up in the directory tree. And those,
in turn, may have overridden directives found yet higher up, or in the
main server configuration file itself.

Inside shop/.htaccess you can use this directive at the top:
RewriteOptions InheritBefore
This forces the current configuration to inherit the configuration of the parent and applies parent rules before current .htaccess rules.
If you are on older Apache i.e. < 2.4 then use:
RewriteOptions Inherit
though remember that parent config will be applied after current set.
