URL Rewrite wordpress -

i want rewrite posts url in wordpress using add_rewrite_rule. if query_var action set. example: example.com/my-post-name-slug/?action=query_action to: example.com/my-post-name-slug/query_action

is possible?

htaccess

# begin wordpress <ifmodule mod_rewrite.c> rewriteengine on  rewritebase /hot/ rewriterule ^ajax/([^/]*)/([^/]*).html$ /hot/wp-admin/admin-ajax.php?action=$1&movie_id=$2 [l]  rewritecond %{request_filename} ^\?action\=$  rewritecond ^\?action\= ^/?$  rewriterule ^index\.php$ - [l] rewritecond %{request_filename} !-f rewritecond %{request_filename} !-d rewriterule . /hot/index.php [l]   </ifmodule>  # end wordpress 

update: solve

add_rewrite_rule('^slug/([^/]*)/([^/]*)/?','index.php?post_type=tpp&name=$matches[1]&action-query=$matches[2]','top'); 

you do

rewriteengine on
rewritecond %{request_filename} ^\?action\=$
rewritecond ^\?action\= ^/?$

should work
