   add_filter('query_vars', 'recent_queryvars' );
   function recent_queryvars( $qvars ) {
       $qvars[] = 'month';
       return $qvars;
   }

   I have been trying to add the query variable of month with no success. The above code is inside functions.php of my theme; and I try to access the variable using get_query_vars( 'month' ); inside ../theme_dir/includes/recent.php. It returns nothing.

   Also I am using post name as my urls (http://domain.com/sample-post/).

   Please don't tell me how to just access the variable, the issue is with add_filter, it doesn't seem to work on query_vars but I know add_filter works because I use it to add a shortcode right above it in my functions file (see below).

   Hopefully someone can tell me what's wrong.

   You don't say what sort of form or url is being submitted, so I'm totally guessing. If the form has no field named month with a value or the url has no parameter named month with a value, there will be no query var for month.

   What you are providing in the filter is a name to look for. If the name does not show up in the request, no query var will be created for it.

   Here is a regular request: http://domain.com/sample-post/
   Here is a request with pagination: http://domain.com/sample-post/3/
   Here is a request with month: http://domain.com/sample-post/?month=4
   Here is a request with both: http://domain.com/sample-post/3/?month=4

   The variable month is never collected from the query string, with my OP code inside functions.php

   Thank you for the extra information. I agree everything seems to be in order. Though you admonished us not to tell you how to access query vars, I strongly suggest trying this:
   get_query_var( 'month' );
   No 's' in 'get_query_var'
