在wordpress中音译现有的西里尔语slug（postu name）

Posted 2021-02-25

While working on the iteration of a blog with russian contents we had to change the slugs from cyrillic to transliterated russian.

[RusToLat](http://mywordpress.ru/plugins/rustolat/) is a great plugin that does just that, but unfortunately it only does the transliteration for new or "edited" posts (i.e. you have to open the post at least once and "edit" the permalink, then it will be transliterated).

Since this blog more than 500 posts this manual updating wasn't an option so we wrote this simple script. Maybe it will save somebody some time.

You'd probably better back-up your database before updating it (google for mysqldump syntax).

<?php
define('BASEPATH','');
 
// just a helper func to see how long it took to process slugs
function microtime_float(){
    list($usec, $sec) = explode(" ", microtime());
    return ((float)$usec + (float)$sec);
}
$time_start = microtime_float();
 
// replace %root% and %secret% with your database credentials
$db = mysql_connect('localhost', 'root', 'secret');
// replace %wordpress_db% with your database
mysql_select_db('wordpress_db', $db);
 
$sql="";
 
// this dictionary is copied from the source of http://mywordpress.ru/plugins/rustolat/ 
// which is great, but only works for new posts
// in the situtation when I had > 500 posts it was easier to write this script
// than to go one by one updating slugs
