问题描述：

I have a functionality on first page it lists all states on click of any states in next page it lists cities related to that state and on click f city it shows city page.

originally url for city listing page was

I have added url rewrites successfully for this page using this code

function rewrite_state_url(){
add_rewrite_rule(\'^get-help/([^/]*)/([^/]*)/?\',\'index.php?
page_id=2931&lp=$matches[1]&state=$matches[2]\',\'top\');
}
function register_custom_query_vars($vars){
array_push($vars, \'lp\');
array_push($vars, \'state\');
return $vars;
}
add_action(\'init\',\'rewrite_state_url\',1);
add_filter(\'query_vars\', \'register_custom_query_vars\',1);

So its showing url like i wanted

But i am trying now same for city page which will take parameter lastpage, state and city.

so i have added code like

function rewrite_city_url(){
add_rewrite_rule(\'^get-help/([^/]*)/([^/]*)/([^/]*)/?\',\'index.php?page_id=2944&lp=$matches[1]&state=$matches[2]&city=$matches[3]\',\'top\');
}
function register_custom_query_vars1($vars){
array_push($vars, \'lp\');
array_push($vars, \'state\');
array_push($vars, \'city\');
return $vars;
}
add_action(\'init\',\'rewrite_city_url\',2);
add_filter(\'query_vars\', \'register_custom_query_vars1\',2);

now its showing url https://benefitsexplorer.com/get-help/unclaimed-money/North%20Carolina/Locust/

but its showing same page which is showing at state list url https://benefitsexplorer.com/cities/?lp=unclaimed-money$state=North%20Carolina/
