Custom fields are a powerful feature of WordPress that allows users to add additional data to their posts, pages, and custom post types. They provide a way to store and display information beyond the standard fields provided by WordPress.


Custom fields are also known as post meta fields, and they allow users to add custom metadata or additional information about their post or page. This can include anything from text or images to more complex data like dates, prices, or locations.

Custom fields were first introduced in WordPress 1.5 as a way for developers to extend the functionality of WordPress without having to modify the core code. Since then, custom fields have become an essential tool for many WordPress users who want to create more dynamic and customized content.

How Custom Fields Work

Custom fields are created using key-value pairs. The key is the name of the custom field, while the value is the data that will be stored in it. For example, if you wanted to add a custom field for an event date on your post or page, you would create a key called event_date and assign it a value such as November 15th.

Once you have created your custom field, you can then use it in your theme files or plugins by calling the specific key name. This allows you to display the custom data in any way you choose—whether that’s through a simple text output or something more complex like a map or image gallery.

Creating Custom Fields in WordPress

Creating custom fields in WordPress is relatively easy, but it’s important to note that the custom fields panel may not be visible by default in the post or page editor. Here are the steps to show the custom fields panel:

  1. Open a post or page for editing.
  2. Click on the three dots located in the top-right corner of your screen to open the editor options.
  3. Click “Preferences” at the bottom of the list.
  4. Select the “Panels” tab, and toggle the “Custom fields” option.
  5. Click “Enable and Reload.”
  6. The Custom Fields panel should now appear below your content editor.

Once you’ve made sure that your Custom Fields panel is visible, you can start creating new custom fields by following these steps:

  1. Scroll down until you see the “Custom Fields” section below your content editor.
  2. Click on “Enter New” to create a new custom field.
  3. In the “Name” field, enter a unique name for your custom field key (e.g., “event_date”).
  4. In the “Value” field, enter the value you want associated with this key (e.g., “November 15th”).
  5. Click on “Add Custom Field”.

You can also use plugins like Advanced Custom Fields and Pods Framework which offer more advanced features for creating and managing custom fields.

Best Practices for Using Custom Fields

While custom fields can be incredibly useful for adding extra information to your content, there are some best practices you should follow when using them:

  • Use unique keys: Make sure each of your keys is unique so they don’t conflict with other keys used elsewhere on your website.
  • Keep things organized: Use descriptive names when creating keys so that others working on your site can quickly understand what each one does.
  • Don’t overuse them: While it’s tempting to add lots of extra data using custom fields, try not to go overboard as this can make it difficult for users to navigate and understand your content.


Custom fields are an essential part of extending the functionality of WordPress beyond its basic features. With just a few keystrokes, users can create highly customized content that meets their specific needs while keeping their website organized and easy-to-use. Whether you’re an experienced developer looking for more control over how your website works or simply someone looking for ways to improve their content creation process—custom fields are definitely worth exploring!
