# Add a Custom Field to a Post in WordPress

Once a field group has location rules that match, its fields appear on the editing screen and anyone who can edit the post can fill them in.

## What It Does

This page is about entering values, not defining fields. Editors and authors can fill fields; only administrators can change what the fields are.

## Before You Start

- A field group exists and has a location rule matching this content.- You can edit the post.

## Fill In a Field

- Open the post for editing.

- In the block editor, open the **Meta Boxes** drawer at the bottom of the screen if it is collapsed — WordPress ships it closed.

- Find the field group by its title.

- Enter the values.

- Click **Save** or **Update**. Field values are stored with the post, not saved separately.

## When to Use It

- Entering a price and availability date on a listing.- Attaching a brochure to a product.- Choosing a listing agent from a user field.

## Limitations

- Values save with the post. Adding a repeater row or picking an image does not save anything until you update the post.- A field added to the group today is empty on every existing post until someone fills it in.

## Troubleshooting

### I cannot see the fields on the editing screen

In the block editor the meta box area is collapsed by default — open the **Meta Boxes** drawer. If it is still missing, the group’s location rules do not match this post.

### My changes disappeared

The post was not saved. Field values are part of the post, so they need an Update like any other change.
