Introduction
In this article, we will show you how to implement custom fields in the Gutenberg editor. Custom fields are a great way to add extra data to your posts and pages. They can be used to store any kind of data, including text, numbers, dates, images, and more. By default, the Gutenberg editor does not include any custom fields. However, there are a few plugins that you can use to add custom fields to Gutenberg. In this article, we will show you how to use the Advanced Custom Fields plugin to add custom fields to Gutenberg.
Installing the Advanced Custom Fields Plugin
First, you need to install and activate the Advanced Custom Fields plugin. For more details, see our article on how to install a WordPress plugin. Upon activation, you need to visit Custom Fields » Add New page to create your first custom field group. Give your field group a name, and then click on the Add Field button to add your first custom field.
Creating Custom Fields in ACF
On the next screen, you need to provide a label for your custom field and choose a field type. ACF comes with a bunch of pre-built field types such as text, text area, number, email, url, image, file, select, checkbox, radio button, and more.
For our example, we will create a text field type for the “Job Title” field. You can provide a default value, placeholder text, and a few other options. Once you are satisfied with your settings, click on the Publish button to save your changes.
You can now add more fields or click on the Publish button to save your field group. Now that you have created your custom field group, it is time to add it to the Gutenberg editor.
Adding Custom Fields to Gutenberg
In order to add custom fields to Gutenberg, you need to edit the post or page where you want to add the custom fields. On the post edit screen, you will see the new “Custom Fields” sidebar. By default, it is collapsed. You need to click on the “Screen Options” tab in the top-right corner of the screen and then check the box next to “Custom Fields”.
This will display the custom fields sidebar. You can now click on the “Add Custom Field” button to add your custom fields. On the next screen, you need to select the field group you created earlier. After that, select the field you want to add, and then click on the “Add Field” button. Once done, you will see your custom field added to the post edit screen.
You can now add a value for your custom field and update the post. That’s all, you have successfully added custom fields to the Gutenberg editor.
In the early days of WordPress, custom fields were added to a post by opening the Custom Fields meta box and adding a new custom field. The custom field name and value were then added.
With the introduction of the Gutenberg editor in WordPress 5.0, the process for adding custom fields has changed. In this article, we’ll show you how to add custom fields to your Gutenberg blocks.
Gutenberg uses a concept called “meta-fields” to store data. Meta-fields are similar to custom fields, but they’re stored in a different location in the database. Gutenberg comes with a built-in meta-field for the Featured Image, but you can also add your own custom meta-fields.
To add a custom meta-field to a Gutenberg block, you first need to create a new block. In your block’s PHP file, you’ll need to add a few lines of code to register the meta-field.
/**
* Register a meta-field for a Gutenberg block.
*
* @param string $name The meta-field name.
* @param array $settings The meta-field settings.
* @return void
*/
function my_block_register_meta_field( $name, $settings = array() ) {
// Make sure the name is prefixed with ‘my_’.
$name = ‘my_’ . $name;
// Set the default settings.
$defaults = array(
‘type’ => ‘string’,
‘default’ => ”,
‘show_in_rest’ => true,
);
$settings = wp_parse_args( $settings, $defaults );
// Register the meta-field.
register_meta( ‘post’, $name, $settings );
}
Once you’ve registered the meta-field, you can add it to your block using the “register_meta_fields” filter.
/**
* Add a meta-field to a Gutenberg block.
*
* @param array $fields The existing meta-fields.
* @return array $fields The modified meta-fields.
*/
function my_block_add_meta_field( $fields ) {
// Add a new meta-field.
$fields[] = array(
‘name’ => ‘my_field_name’,
‘label’ => __( ‘My Field Label’, ‘my-text-domain’ ),
‘type’ => ‘text’,
‘default’ => ”,
);
return $fields;
}
add_filter( ‘register_meta_fields’, ‘my_block_add_meta_field’ );
Now that you’ve added the meta-field to your block, you can access the value in the PHP code for your block. To do this, you’ll need to use the “get_post_meta” function.
/**
* Get the value of a meta-field.
*
* @param int $post_id The post ID.
* @param string $field The field name.
* @param mixed $default The default value.
* @return mixed
*/
function my_block_get_meta_field_value( $post_id, $field, $default = ” ) {
$value = get_post_meta( $post_id, $field, true );
if ( $value === ” ) {
$value = $default;
}
return $value;
}
You can also update the value of a meta-field using the “update_post_meta” function.
/**
* Update the value of a meta-field.
*
* @param int $post_id The post ID.
* @param string $field The field name.
* @param mixed $value The new value.
* @return void
*/
function my_block_update_meta_field( $post_id, $field, $value ) {
update_post_meta( $post_id, $field, $value );
}
And that’s all there is to adding custom fields to Gutenberg blocks. By following the steps in this article, you can add as many custom fields as you need to your blocks.
Gutenberg provides a number of ways to add custom fields to your posts and pages. In this article, we’ll cover how to add custom fields to Gutenberg blocks.
Adding custom fields to blocks is a two-step process. First, you’ll need to register the custom field with Gutenberg. Second, you’ll need to add the custom field to the appropriate block.
To register a custom field with Gutenberg, you’ll need to add some code to your theme or plugin. The code will look something like this:
add_action( ‘init’, ‘my_register_custom_fields’ ); function my_register_custom_fields() { register_rest_field( ‘post’, ‘my_custom_field’, array( ‘get_callback’ => ‘my_get_custom_field’, ‘update_callback’ => ‘my_update_custom_field’, ‘schema’ => null, ) ); }
This code registers a custom field called “my_custom_field” with the “post” post type. The “get_callback” function specifies what should happen when the custom field is retrieved. The “update_callback” function specifies what should happen when the custom field is updated. The “schema” parameter is optional and can be used to specify the data type of the custom field.
Once you’ve registered the custom field, you can add it to any block that supports custom fields. To do so, edit the block and look for the “Custom Fields” panel. Click the “Add Custom Field” button and select the custom field you want to add.
Custom fields can be used to store any kind of data, including text, numbers, dates, and file attachments. They’re a great way to add extra data to your posts and pages without having to edit the code.
