可以使用the_permalink 使用筛选和添加重写规则add_rewrite_rule 将新的永久链接重定向到标准post链接。

function mysite_modify_permalink($url) {

  //if taxonomy archive for Series get term
  $term = is_tax(\'Series\')?get_query_var(\'term\'):\'\';
  if(empty($term)) { //if no term was found
    //get all Series terms for current post
    $terms = get_the_terms($post, \'Series\');
    //if terms were found, take first term found
    if(!empty($terms) && is_array($terms)) $term = $terms[0]->slug;
  }
  //if term was found return a modified permalink url
  //(replace last url segment starting from \'/\' with \'/<term slug><last segment>\')
  if(!empty($term)) return preg_replace(\'#/blog(/[^/]+/?)$#\', \'/blog/\'.$term.\'$1\', $url);
  //else return original url
  else return $url;
}
add_filter(\'the_permalink\', \'mysite_modify_permalink\');

function mysite_add_rewrule() {
  //get all Series terms
