3) PHP Array Schema

Here is an example of how to use the number control in a post meta configuration:

[
    'fieldType' => 'number',
    'name' => 'post_number',
    'fieldLabel' => 'Post Number',
    'required' => false,
    'disabled' => false,
    'hideLabelFromVision' => false,
    'fieldHelpText' => 'Enter a numeric value.',
    'className' => 'custom-class',
    'fieldLabelPosition' => 'top',
    'fieldLabelTextTransform' => 'uppercase',
    'min' => 0,
    'max' => 100,
    'step' => 1,
    'spinControls' => 'native',
    'isShiftStepEnabled' => true,
    'isDragEnabled' => false,
]

3) Hook-Based Example (Post Meta Config)

It is available to use this control in post meta fields, term meta fields and user settings page and options page fields.

Available hooks:

• native_custom_fields_post_meta_fields
• native_custom_fields_term_meta_fields
• native_custom_fields_user_meta_fields
• native_custom_fields_options_page_fields

add_filter( 'native_custom_fields_post_meta_fields', function( array $configs ): array {
    $post_type = 'book';

    if ( ! isset( $configs[ $post_type ] ) || ! is_array( $configs[ $post_type ] ) ) {
        $configs[ $post_type ] = [
            'post_type' => $post_type,
            'sections'  => [],
        ];
    }

    $configs[ $post_type ]['sections'][] = [
        'meta_box_id'       => 'post_options',
        'meta_box_title'    => 'Post Options',
        'meta_box_context'  => 'side',
        'meta_box_priority' => 'default',
        'fields'            => [
            [
            'fieldType' => 'number',
            'name' => 'post_number',
            'fieldLabel' => 'Post Number',
            'required' => false,
            'disabled' => false,
            'hideLabelFromVision' => false,
            'fieldHelpText' => 'Enter a numeric value.',
            'className' => 'custom-class',
            'fieldLabelPosition' => 'top',
            'fieldLabelTextTransform' => 'uppercase',
            'min' => 0,
            'max' => 100,
            'step' => 1,
            'spinControls' => 'native',
            'isShiftStepEnabled' => true,
            'isDragEnabled' => false,
            ],
        ],
    ];

    return $configs;
} );
