Show modified Date in admin lists


This plugin shows a new, sortable, column with the modified date in the lists of pages and posts in the WordPress admin panel. It also shows the username that did the last update.

We needed this functionality for one of our websites and didn’t find a suitable plugin for it. The idea of our plugin is based on the plugin Sort by modified which has some problems displaying the information correctly in latest WordPress versiones. We love Admin Columns, but the free version doesn’t allow sorting the columns.

We also have included translations which are important for us as we are based in Valencia (Spain).


This first release is avaliable in English and Spanish. In the languages folder we have included the necessary files to translate this plugin.

If you would like the plugin in your language and you’re good at translating, please drop us a line at Contact us.

Translating WordPress Plugins

The steps involved in translating a plugin are:

  1. Run a tool over the code to produce a POT file (Portable Object Template), simply a list of all localizable text. Our plugins allready havae this POT file in the /languages/ folder.
  2. Use a plain text editor or a special localization tool to generate a translation for each piece of text. This produces a PO file (Portable Object). The only difference between a POT and PO file is that the PO file contains translations.
  3. Compile the PO file to produce a MO file (Machine Object), which can then be used in the theme or plugin.

In order to translate a plugin you will need a special software tool like poEdit, which is a cross-platform graphical tool that is available for Windows, Linux, and Mac OS X.

The naming of your PO and MO files is very important and must match the desired locale. The naming convention is: language_COUNTRY.po and plugins have an additional naming convention whereby the plugin name is added to the filename: pluginname-fr_FR.po

That is, the plugin name name must be the language code followed by an underscore, followed by a code for the country (in uppercase). If the encoding of the file is not UTF-8 then the encoding must be specified.

For example:

  • en_US – US English
  • en_UK – UK English
  • es_ES – Spanish from Spain
  • fr_FR – French from France
  • zh_CN – Simplified Chinese

A list of language codes can be found here, and country codes can be found here. A full list of encoding names can also be found at IANA.

Please use with WordPress MultiSite at your own risk, as it has not been tested.



This plugin shows a new, sortable, column with the modified date in the lists of pages and posts in the WordPress admin panel. It also shows the username that did the last update.

Does SHOW MODIFIED DATE IN ADMIN LISTS make changes to the database?


How can I check out if the plugin works for me?

Install and activate. Go to the pages or post list in the administration of WordPress. There you should see a new column with the modified date.


You can simply activate, deactivate or delete it in your plugin management section.

Are there any known incompatibilities?

Please don’t use it with WordPress MultiSite, as it has not been tested.

Do you make use of SHOW MODIFIED DATE IN ADMIN LISTS yourself?

Of course we do. 😉

Por fin un simple plugin (quiero decir sin un montón de opciones) para una funcionalidad indispensable. Sería aún mejor si se pudiera añadir la fecha de actualización en la lista de plugins y también la fecha de modificación en la lista de usuarios.

the_modified_time('F j, Y') in the code where is normally says .get_the_modified_time() That change showed me day, month and year just fine, not just time.

The default WordPress sorting function does not work as expected. I didn't noticed that earlier but i needed to check the difference of Staging and Live site and i was surprised to see only one page was modified in a month (which was not true in my case i did a lot of modifications), That brought me to search this plugin, Works Perfect! Thanks

This is what we needed. It just works and no config required. Admin columns is also great, but much more than we required and the freee version does not have a column sort feature.

In the process of making updates to my pages, this makes my job so much easier as I can see when they were last modified. Simple and useful.
