If you are wondering how to display your page's modified/updated date along with or instead of the page published date in the Oxygen Templating, then in this post I will teach you how to do that within a few minutes.
You only need to know how to copy and paste the provided code snippet to your WordPress site using the Code Snippets, Advanced Scripts, or any other similar plugin.
Also, I assume that you are already comfortable with Oxygen Dynamic Data options as we are going to use that extraordinary feature to display the last modified date of the page to the Oxygen template.

Even if you don't know how to use them properly still no worries, just follow the post carefully and I will teach you everything step by step.
Register a PHP Function To Display Last Modified Date in Oxygen Templates
The very first step is to install and activate the Code Snippets plugin, then add a new code snippet after that just copy the provided PHP code snippet you can find below and paste that to register a function to call the last modified date.
/* Display Last Modified Date in Oxygen Templates */ function syncwin_display_last_modified_date( ) { return get_the_modified_time('F j, Y'); }
Special thanks to Matt Hias for helping me to improve the old bloated code snippet with a new optimized version.
Add The Page Modified Date Using Oxygen Dynamic Data Feature
The final step is to add a text element to your template and then select the texts and you will find an Insert Data button on top of the Oxygen editor.
Once you click that button you will see a pop-up window called Insert Dynamic Data, now just click over to the PHP Function Return Value button under the Advanced section.

Once you click on that option you will see two fields, the first one is a Function Name and the second one is the Function Arguments field.
In the Function Name field, you need to insert "syncwin_display_last_modified_date" which is our function name that you also can see in the first line of the code snippet I provided, now leave the second Function Argument field blank as we don't need that in this case.
Next just hit the Insert button on the same window and click the Save button from the top right corner of the Oxygen editor.
Now you can see the page Updated/Modified Date on the front-end of your Oxygen page once you reload the page.

The Navigation Should Look Like This:
> Open the Oxygen Editor
> Click the +Add Button
> Add a text element
> Double click on that particular element to select the texts
> Hit the Insert data button from the top of the page
> Select the PHP Function Return Value button under the Advanced section
> Insert "syncwin_display_last_modified_date" in the Function Name field
> Leave the PHP Argument field blank
> Hit the Insert button
> Save the Oxygen Template using the Save button from the top right corner

Thanks for visiting Toolonomy.com!
Thanks for this snippet! It really helped me a lot. Could you please provide me with a small addition? I want the date shown in the german form, e.g. 30. März 2021 (month written the german word of the month and the year with 4 nummers). If I write d.m.y I only get 30.03.21
Thanks for your help 🙂
Hi Catharina,
you can use 'd. F Y' as the format string in the function.
d = 2 digit day
F = full month name in your WordPress language (hopefully German?)
Y = 4 digit year.
See the PHP doc for details:
https://www.php.net/manual/de/datetime.format.php
If you Google "PHP date format" or "PHP date German" I am sure you will be able to figure it out. It uses universal PHP date format so you can just change it.
A simple article but really helpful, thanks Mohammed. I am trying to get this to help with Google.
You're most welcome Colin 😊
Hi Mohammed, I'm not sure if my problem is relevant to this snippet, Oxygen or Polylang.
I use two languages – English and Czech. In English, I need to use this date format: 'F j, Y' – it works fine. In Czech, I need to use 'j. F Y'.
I tried translating F j, Y to j. F Y in Languages > Strings Translations but that didn't help. Any idea how to fix this?
I'm attaching some screenshots:


Code Snippet:
English frontend (works fine):
Czech frontend (missing the dot after day + extra comma after month):
Hey Slavek, I only tested this snippet with English therefore I'm not sure if it will properly function with other languages or not.
Consider sharing the post with someone from the Oxygen community who knows Czech they might help you achieve what you want.
Hi Mohammed,
Simple enough, it seems, but all I see is the first creation date of the template, not the date of the latest update.
What am I doing wrong?
If you properly follow and implement the steps from this tutorial, it should display the page's last modified date without any issues. I have been using it for all my websites in fact on this very article the last updated date is visible.
Hi Mohammed,
You're absolutely right. I started all over again and it works.
Haven't the faintest clue what went wrong the first time.
ThnX a lot!
Kind regards,
Ton
Sounds great! I am glad that it worked for you.
When implementing the snippet do you "Run snippet everywhere" or "Only run on site front-end". Thanks
front-end would be just fine.
