You likely already know how crucial performance is to a successful website if you work as a WordPress developer. However, it can be difficult to comprehend WordPress transients and how they’ll assist you in optimizing your projects.

Fortunately, transients aren’t that hard to grasp once you break them down. You should have no trouble adding them to your next WordPress plugin if you remember a few important guidelines.

In this post, we’ll walk you through transients in WordPress and how and when to use them. Let’s get right to it, as there are a lot of points to cover!

1 What Are WordPress Transients?

Transients are a standardized way of temporarily storing cached data in the database by giving it a custom name and timeframe, after which it will expire and be deleted. Transients have the advantage of self-expiring over other caching techniques. It is also storage-efficient because, with each transient record, there is also a record of when the transient should expire.

Transients are more secure, store many data types, and are easily programmable. This allows for faster page load times, as the browser doesn’t have to go back to the server whenever you want to display something on the page.

A transient consists of three parts:

  • $transient. This is the string used to identify your transient. It’s also known as the transient’s ‘key’ or ‘name.’
  • $value. This data is being retrieved using an API. The value of a transient can be a text, a number, an object, or an array.
  • $expiration. This is the time that a transient is stored in your database before it is deleted, and you have to use the API to obtain the information once again.

Most of the time, transients are invisible to your visitors; however, when you want to customize a part of your site’s design or add functionality to parts of your site that are not visible to the visitor, transients can be used to store and restore data on the fly. The only downside is that transients require extra work when building a site or a theme.

Now let’s take a look at when you can use transients in WordPress.

2 When to Use WordPress Transients?

Transients are removed from your database after their expiration term is completed. Because of this, you should only use them for continuously re-created information.

Additionally, transients are best suited for large queries and remote calls and can boost your project’s performance.

The most common use case for WordPress transients is resource-intensive queries. For example, multiple users asking the same database-intensive query simultaneously can seriously impact the website’s performance. But with a transient, the needed information can be temporarily cached, and the whole expensive process can only be instigated if someone tries to retrieve data from a transient that expired.

You’re better off not using a transient if doing so requires more code than it will just to make a new request for the resource each time it is needed.

3 Basic Operations Using Transients

There are three basic operations you’ll most likely utilize while creating your own transients. Let’s have a look at the basic operations.

3.1 Save the Transient

To save the transient, use the below syntax.

set_transient( $transient, $value, $expiration );

Do not forget to replace the appropriate values with real ones. For example, here’s how the code will look using set_transient() function.

set_transient('Website', $result, 3600);

Here we are storing a key named ‘Website’ with the value ‘result’ for 1 hour. After 1 hour, the key will not be accessible anymore.

3.2 Retrieve the Transient

You can fetch a transient you’ve saved using the below syntax. The get_transient() will return false if the transient is expired or is not present. Otherwise, it returns the value of the transient.

get_transient( $transient );

3.3 Delete the Transient

To delete the transient use the below syntax. It takes only one parameter i.e. the transient’s name.

delete_transient( $transient );

In our example it would be:

delete_transient( $result );

WordPress infrequently removes transients that have expired. Always remove your transient once you no longer need it to avoid expired transients piling up in the database.

4 How to Manage WordPress Transients?

The Transients Manager plugin is the most effective way to manage and remove WordPress transients. The plugin makes it simple to edit, delete, and manage your WordPress transients.

You need to install and activate the plugin by navigating to Plugins → Add New section from your WordPress dashboard. Search for the Transients Manager plugin and install and activate the plugin, as shown below.

You can select the transient and perform the bulk actions by selecting from the Bulk actions drop-down list. It allows you to perform the following bulk actions:

  • Delete selected transients
  • Delete expired transients
  • Delete all transients with an expiry date
  • Delete all transients without an expiry date
  • Delete all transients

To edit specific transients, click the Edit link in the Actions column. This opens up a panel that lets you set the value, expiration time, and even rename the transient.

Once you’ve edited the transient, click on the Save Changes button to save your changes.

If you’re using Rank Math plugin, you can use the Remove transients option to clear all the transients created by Rank Math. To do so, navigate to Rank Math → Status & Tools → Database Tools from your WordPress dashboard. Click the Remove transients button, and all the transients will be cleared.
