Multiple items

Register fields that only display when multiple items are being edited. Each field returns only its type. Fields are registered in PHP and sanitization is handled by Index.

Registering a multiple item edit field

Each edit field is tied to a specific post type:

// replace {$type} with the post type name
add_filter("index_{$type}_edit_fields", function($fields) {
	return $fields;

See the Creating fields [LINK] document for more information on how to format fields.


add_filter("index_post_edit_fields", function($fields, $post_id) {
	$fields[] = [
		'id' => 'custom_field_id',
		'label' => 'Custom field name',
		'type' => 'meta',
		'component' => 'text',

	return $fields;
