问题描述：

I have a page called used-cars and I\'m trying filter its title and display it as an H1 header. I have rewrite the permalink structure to pass double terms e.g example.com/used-cars/term1/term2 and it works like a charm

So at this point. I\'m trying to filter the page title to match the URLs, but I just can\'t get it to work with this code

`add_filter( \'wp_title\', \'new_listing_title\', 10, 1 );

      function new_listing_title($title)
{
if ( is_page(\'used-cars\') && $id = get_queried_object_id() )
{
$locations = get_query_var(\'area\');
$location = get_term_by(\'slug\', $locations, \'area\');
$models = get_query_var(\'serie\');
$model = get_term_by(\'slug\', $models, \'serie\');
$title = \'\';
if($model && $model) $title .= $model->name . \' Used\';
else $title .= \'Used\';
$title .= \' Cars For Sale\';
if($location && $location) $title .= \' In \' . $location->name;
return $title;
}
return $title;
}`

However when I use this. it works

global $wp_query;

echo \'Car : \' . $wp_query->query_vars[\'serie\'];

echo \'<br />\';

So how can I Incorporate these two solutions to filter the title of this page\'s title?
