Permalinks Migration Plugin for wordpress

2 10 2008

With this plugin, you can safely change your permalink structure without breaking the old links to your website,and even doesn’t affect your search engine rankings.


Many people want to change their permalink structure,for example, from /%year%/%monthnum%/%day%/%postname%/ to /%category%/%postname%/

But doing so will make all pages indexed by search engines become invalid,moreover, losing visitors from other sites or bookmarks that links to you.

There is a way to tell the search engines (and browsers) that the page has permenantly moved, and that the old address should be replaced by the new one . It’s called a “301 Redirect”, also known as a Permanent Redirect.When you do this, Search engines will update their indexes quickly and you won’t lose your will continue to receive traffic as though nothing had changed. This works for search engines, bookmarks, and links from other sites.

By now, you know how can you change your permalinks without losing the traffic you’re already getting. You can download this Permalink Migration Plugin to achieve this for you.

This plugin will generates a “301 Redirect” when user or spider visit your site through old permalinks,and redirect them to the new permalinks of the same post.

Do not fear to change your permalink structure now, you would never lose any visitors due to changed addresses.



  1. unzip and upload the file into your wp-content/plugins/ directory.
  2. Activate it on your Admin Panel->Plugin Management page.


  1. goto admin panel->options->PermalinksMigration.set the old permanlink structure of your site.
  2. goto admin panel->options->Permalinks.change the new permalink structure to what you want. (personally I recommend /%category%/%postname%/)
  3. Done,enjoy it.


Many thanks to all of you, who have encouraged me to update my articles  and code, and who sent in bug reports and fixes.


Sitemap Generator Plugin for Wordpress

2 10 2008

This plugin creates a sitemap for your WordPress powered site. This is not just another XML sitemap plugin, but rather a true sitemap generator which is highly customizable from its own options page in the WordPress admin panel. Some of its features include: support for multi-level categories and pages, category/page exclusion, multiple-page generation with navigation, permalink support, choose what to display, what order to list items in, show comment counts and/or post dates, and much more. To see this plugin in action, visit my sitemap page.

I am currently experimenting with the WordPress Extend database to manage the downloading of plugins. Because of this, the folder name for the plugin is currently ’sitemap-generator’ instead of ‘dd-sitemapgen’.

If you are upgrading, please delete the ‘dd-sitemapgen’ folder before uploading the new version.



The latest version of this plugin includes complete support for language files. If you would like to submit a translation, please contact me. You can choose the language from the options page.

Current languages: English, Albanian, Brazilian-Portuguese, Bulgarian, Czech, Dutch, French, German, Italian, Japanese, Lithuanian, Polish, Romanian, Russian, Simplified Chinese, Slovene, Spanish, Swedish, Turkish, Ukrainian

The language file contains not only the text shown on the sitemap page, but all of the text in the options page as well.

  • Download and uncompress
  • Upload the entire sitemap-generator folder (not just the files inside) to your plugins directory
  • Activate the plugin in your administration panel
  • Configure the plugin in the options panel (under DDSitemapGen)
  • If using permalinks, read the permalink section below
  • Simply add the following line to a WordPress page (where you would like the sitemap to display):
    <!-- ddsitemapgen -->

    Note: For those of you using the new rich-text editor – be sure to click the ‘html’ button to edit the page source directly. Otherwise WordPress will wrap code tags around the line which generates the sitemap and it will not work properly.


To upgrade, disable and then delete the existing plugin. Then install the new version as explained above.

After you install, be sure to click the ‘Load Default Options’ button, as some of the settings have changed.

Version 3.0 of this plugin is a big jump from the previous versions. Most of the code has been rewritten from scratch, and a few things are different. One of the best improvements is the speed and stability. The sitemap generation is much faster now, which should especially help people with larger sites. Be sure to read the updated information below.

Want to run the plugin from a template file?

To use the sitemap generator function directly from a template file, just insert the following line where you would like the sitemap to be generated:

<?php echo ddsg_create_sitemap(); ?>

Permalinks for sitemap navigation

Depending on your settings, the sitemap may be spread across multiple pages. If you are using permalinks, be sure to enter the page slug of your sitemap page in the plugin options. That way it will use permalinks for the sitemap navigation as well. If you are not using permalinks, simply leave this option blank.

CSS declarations

This plugin has a couple of CSS classes built in to easily change the look of your sitemap. Just add the new declarations to your themes CSS file, and customize it however you like.

  • .ddsg-wrapper – Div around the entire sitemap.
  • .ddsg-pagenav – Div around the page navigation.

Available Options

These options can be configured from the options page in the WordPress admin panel. Most of these are fairly self-explanatory.
