如何用 - 替换％20

How to replace %20 with -. (Wordpress)

So what i need: link like ://www.yyy.xx/tag/55 5/

should change in ://www.yyy.xx/tag/55-5/

instead of: http://www.yyy.xx/tag/55%205/

Try using str_replace for that.

like for example.

$url = "http://www.yyy.xx/tag/55%205/";
$url = str_replace('%20', '-', $url);

You can try something like this. That filter changes your URL. I wrote it here so I don't test it if doesn't work try to experiment to fetch tag.

    function custom_link($link, $term, $taxonomy) {
       if ( is_tag() ) {
         return $link;
       }
       return str_replace('%20', '-', $link);
    }
    add_filter('tag_link', 'custom_link', 10, 3);

or

    $url = 'http://' . $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI'];
    function custom_link() {
      if (strpos($url,'%20') == true) {
        return str_replace('%20', '-', $url);
      } 
    add_filter('tag_link', 'custom_link', 10, 3);
