How to Adjust the Auto-Save Interval in WordPress

Have you ever been in the flow, crafting a masterpiece on your WordPress website—a captivating blog post, a compelling article, or a persuasive product description—only to be interrupted by an unexpected event like a browser crash or a computer restart? The fear of losing all your hard work can be daunting. Fortunately, WordPress includes an auto-save feature that periodically saves your content. By default, WordPress auto-saves your work every 60 seconds, which is quite handy. But what if you have specific preferences or needs? Perhaps you want to reduce the auto-save interval for enhanced performance or increase it to minimize server load. In this tutorial, we’ll guide you through adjusting the auto-save interval in WordPress, tailoring it precisely to your requirements.

Before proceeding with any customizations in WordPress, it’s essential to set up a child theme. A child theme acts as a safe and efficient way to make modifications without affecting the parent theme. If you haven’t set up a child theme yet, follow this tutorial on How to Create a Child Theme for Customization. It will guide you through the process and ensure that your customizations remain intact even after theme updates.

Add to Functions.php File

We’ll adjust the auto-save interval using a code snippet in your functions.php file. You can change the interval for various reasons, such as improving performance or customizing the experience to your liking. In this example, we’ll set the interval to every 3 minutes (180 seconds) for a balance between frequent saves and server load considerations.

if ( ! defined( 'AUTOSAVE_INTERVAL' ) ) {
    // Change 180 to the number of seconds you prefer (3 minutes in this example).
    define( 'AUTOSAVE_INTERVAL', 180 );
Code language: PHP (php)

Code Explanation:

  • The code checks if the AUTOSAVE_INTERVAL constant is defined. If not, it sets it to the specified interval in seconds.
  • define( 'AUTOSAVE_INTERVAL', 180 ); is where the magic happens. Here, we’re defining the AUTOSAVE_INTERVAL constant, which WordPress uses to determine how frequently it auto-saves your work.
  • The value 180 represents the auto-save interval in seconds. In this example, we’ve set it to 180 seconds, which is equivalent to 3 minutes (1 minute = 60 seconds).

So, why might you want to change this interval?

Performance Optimization: A shorter auto-save interval can help protect your work by saving it more frequently. However, it may also result in more database writes, which could affect server performance. A longer interval can reduce server load and improve performance but might risk losing more unsaved work in case of an unexpected event. It’s about finding the right balance for your needs.

Customization: Tailoring the auto-save interval allows you to match your workflow. If you’re frequently making small edits and want to minimize data loss, a shorter interval may be suitable. Conversely, for larger projects, a longer interval can prevent distractions caused by frequent auto-saves.

Ultimately, the choice of interval depends on your specific requirements and preferences. This code snippet gives you the flexibility to set it to the desired interval, optimizing your WordPress editing experience.

Save Changes and Verify

After adding the code snippet, click the “Update File” button to save your changes. WordPress will now use the new auto-save interval you’ve defined. To confirm that your changes have taken effect, create or edit a post or page. You’ll notice the auto-save message appears according to the interval you set before.

That’s it! You’ve successfully adjusted the auto-save interval in WordPress, giving you more control over your editing experience. Whether it’s for performance optimization or customizing your workflow, this simple customization can make a significant difference.
