如何从过滤器结果的 URL 获取 UTM 到页面上的文本？

Question

I am using a plugin (directories). If I filter directories I get something like this

/?filter_field_age%5B%5D=35&filter_field_regions%5B%5D=America

I want to get "35" and "America" to appear on page as text.

I used

function UTMParam( $atts ) {  
    extract( shortcode_atts( array(
        'param' => 'param',
    ), $atts ) );
    return $_GET[$param];  
}
add_shortcode('UTMParam', 'UTMParam'); 

and

[UTMParam param='filter_field_age'] [UTMParam param='filter_field_regions']

But its not working....any idea????

You can use parse_str , but you'll have to strip the /? first :

$str = '/?filter_field_age%5B%5D=35&filter_field_regions%5B%5D=America';
$query = parse_url($str, PHP_URL_QUERY);
parse_str($query, $output);
print_r($output);

Result :

[
  'filter_field_age' => [
      0 => '35',
  ],
  'filter_field_regions' => [
      0 => 'America',
  ],
]
