我希望我的帖子链接看起来像/%post\\u id62%\\u%postname%/其中%post\\u id62%是base62编码中的帖子ID（例如。http://example.com/y9Rlf_test/) 我的短链接由/%post\\u id62%组成（例如。http://example.com/y9Rlf). 这是我到目前为止（在我的functions.php) 这显然不起作用：

add_action( \'init\', \'yoyo_init\' );
function yoyo_init() {
  add_rewrite_tag( \'%post_id62%\', \'([A-Za-z0-9]+)\' );
}

add_action(\'generate_rewrite_rules\',\'yoyo_generate_rewrite_rules\');
function yoyo_generate_rewrite_rules($yoyo_rewrite) {
  global $wp_rewrite;
  $new_rules[\'/([0-9A-Za-z]+)/?$\'] = \'index.php?p=\' .
    base622dec($wp_rewrite->preg_index(1));  // DOESNT WORK OF COURSE (executed only once when rewrite_rules are generated)
  $wp_rewrite->rules = array_merge($new_rules, $wp_rewrite->rules);
}

add_filter( \'post_link\', \'yoyo_post_link\', 10, 2 );
function yoyo_post_link( $permalink, $post ) {
  if ( false !== strpos( $permalink, \'%post_id62%\' ) ) {
    $post_id62 = dec2base62( $post->ID );
    $permalink = str_replace( \'%post_id62%\', $post_id62, $permalink );
  }
  return $permalink;
}

add_filter(\'pre_get_shortlink\', \'yoyo_custom_shortlink\', 10, 4);
function yoyo_custom_shortlink($false, $post_id, $context, $allow_slugs) {
  global $wp_query;
  if($post_id or ($context == \'query\' and $post_id = $wp_query->get_queried_object_id())) {
    return home_url(\'/\' . dec2base62($post_id));
  }
  return false;
}

function dec2base62($number) {
  $digits = \'0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz\';  $string = \'\';  while($number > 0) { $string = $digits[$number % 62] . $string;  $number = floor($number / 62); }
  return $string;
}
function base622dec($string) {
  $digits = \'0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz\';  $number = 0;  while(strlen($string) and ($number *= 62 or strlen($string))) { $number += strpos($digits, $string[0]);  $string  = substr($string, 1); }
  return $number;
}

你知道怎么解决这个问题吗？当创建了另一篇具有相同标题的文章时，避免使用-N slug后缀的额外点数（在将链接结构设置为“/%post\\u id62%\\u%postname%/”时，实际上可以避免使用该后缀，但为了具有短链接功能，我想应该是“/%post\\u id62%”；cf。Turn off %postname% auto-incrementing?)!谢谢
