[wp-hackers] Use a period in permalinks

[Ryan Bilesky]

If all you need is to allow periods, you can use this bit of code. I took
it from the advanced-permalinks plugin, this is how it does that, just add
it to your theme's functions.php

function sanitize_title_allow_period($title) {
 $title = strip_tags($title);
 // Preserve escaped octets.
 $title = preg_replace('|%([a-fA-F0-9][a-fA-F0-9])|', '---$1---', $title);
 // Remove percent signs that are not part of an octet.
 $title = str_replace('%', '', $title);
 // Restore octets.
 $title = preg_replace('|---([a-fA-F0-9][a-fA-F0-9])---|', '%$1', $title);
 $title = remove_accents($title);
 if (seems_utf8($title)) {
  if (function_exists('mb_strtolower')) {
   $title = mb_strtolower($title, 'UTF-8');
  }
  $title = utf8_uri_encode($title);
 }
 $title = strtolower($title);
 $title = preg_replace('/&.+?;/', '', $title); // kill entities
 $title = preg_replace('/[^%a-z0-9\. _-]/', '', $title);
 $title = preg_replace('/\s+/', '-', $title);
 $title = preg_replace('|-+|', '-', $title);
 $title = trim($title, '-');
 return $title;
}

remove_filter ('sanitize_title', 'sanitize_title_with_dashes');
add_filter ('sanitize_title', 'sanitize_title_allow_period', 10, 1);
