Displaying a warning for outdated posts in WordPress is crucial to inform readers that the content may no longer be relevant. By adding custom PHP code to the functions.php file, users can display a warning message for posts that have not been updated in a specified timeframe, such as 2 years. This warning message can be customized and styled using CSS to attract immediate attention. By implementing this feature, users can prevent misinformation and inaccuracies from spreading, encouraging them to seek out more current information. This can ultimately help improve the overall quality and accuracy of content on WordPress websites.
Have you ever wondered how to display a warning for outdated posts in WordPress? It’s a great way to let readers know that the content they’re about to read might be outdated. This warning can help prevent the spread of misinformation and inaccurate data.
Adding a post warning for articles that haven’t been updated in a while is essential. It reminds readers to approach the content with caution and seek out more recent information. In this article, Voc Trinh will walk you through the process of adding this warning without the need for additional plugins.
Step 1: Add custom PHP code
Before you proceed, make sure to create a backup of your WordPress files. You can use backup plugins or the built-in feature provided by your hosting service.
To get started, go to Appearance > Theme File Editor of the Theme you’re using (create a Theme Child first) in the WordPress dashboard. Then, select the file functions.php. Scroll down and paste the provided code.
The above code will display a warning message for articles that have not been updated in over 2 years. You can customize the warning message and adjust the threshold for outdated articles by changing the values of $warning_message and $outdated_threshold respectively.
Now click on the Update File button to save and apply the changes. Your outdated articles will now display a warning before the content.
Step 2: Enhance the notification
To increase the visibility of the warning message, you can add custom CSS to make it stand out and attract user attention. Customize the CSS class wpp-outdated-warning assigned to the warning message in the Appearance > Customization > CSS section.
After adding the custom CSS code, click on Publish to see the results.
