Mastering Gutenberg Forms: DataViews and DataForm

I had a client a few months back with a custom CRM built right into WordPress. Massive headache. Their team was constantly complaining about the clunky admin interface for managing client data – slow, buggy, validation failing on submission. Every field was a bespoke nightmare, and adding new features was, well, let’s just say a total nightmare.

Honestly, it reminded me of the old days, pre-Gutenberg, when building complex data entry screens meant wrestling with meta boxes and custom JavaScript. A developer on the team initially tried to patch things up with a bunch of jQuery and PHP hooks, slapping on fixes wherever validation broke. And yeah, it kind of worked for a bit, but it was like building a house with duct tape. Every WordPress update was a gamble, and the UI felt sluggish and inconsistent.

The problem? They were fighting WordPress, not working with it. Custom data management in Gutenberg used to be a real pain point, but with WordPress 6.9 and the continued evolution of the “dataviews space” – specifically the Field API, DataViews, and DataForm – things have changed dramatically. These aren’t just minor tweaks; they’re foundational shifts that streamline how you build powerful, dynamic, and reliable admin UIs. This is the good stuff, trust me on this.

Gutenberg DataViews: Building Better Admin UIs

The core of this revolution is the Field API and DataViews. Think of the Field API as your toolbox for defining how data behaves: what type it is, how it’s validated, and how it’s rendered and edited. In WordPress 6.9, they’ve expanded the field types from a paltry 3 to a robust 13, including everything from datetime and integer to email and url. This means less custom code for basic field handling. Plus, the Edit property now offers 16 bundled controls, like checkbox, toggle, and textarea, many with configurable options. This gives you consistent UI out of the box.

Take validation, for instance. Before, you were rolling your own logic, which led to inconsistencies. Now, the isValid property is completely overhauled, leveraging a rule-based system. You get built-in required and elements rules, and you can define custom sync or async validation functions. This is a game-changer for data integrity, reducing the amount of error-prone boilerplate you need to write. Here’s a quick look at how you’d define a required text field with a custom validation rule:

<?php
add_action( 'bbioon_register_custom_fields', 'bbioon_setup_my_fields' );

function bbioon_setup_my_fields() {
    bbioon_register_field_type( 'my_custom_text', array(
        'label' => esc_html__( 'My Custom Text', 'bbioontheme' ),
        'type'  => 'text',
        'edit'  => 'text',
        'isValid' => array(
            'required' => true,
            'custom'   => new JS_Callback( 'function( item, field ) {
                if ( item[ field.id ].length < 5 ) {
                    return \'Must be at least 5 characters.\';
                }
                return null;
            }' ),
        ),
    ) );
}
?>

Beyond validation, the introduction of setValue alongside getValue makes working with nested and derived data a breeze. No more complex manual parsing or updates for interconnected fields. You can use dot notation in your field.id (e.g., user.profile.name) and the API handles the heavy lifting. You can even define custom setValue logic to update multiple dependent fields, like calculating a total from price and quantity, right when a related field changes.

DataViews, then, takes these fields and lets you build powerful displays like tables, grids, and lists. WordPress 6.9 adds features like groupByField for easy data grouping, “locked filters” that users can’t remove, and infinite scroll via paginationInfo. For building highly customized UIs, you can even leverage DataViews’ internal state management and data handling while using its subcomponents as children. It’s truly flexible. If you’re building a content picker, say for posts or media, the new DataViewsPicker component is tailor-made for that, providing selection management and action buttons with minimal fuss. For more details, refer to the official dev notes posted on the WordPress Core blog, which this post builds upon for a practical developer perspective.

Why This Matters to Your WordPress Projects

Look, the old way of building custom admin UIs was a hack-fest. We’ve all been there, pushing out something that “works” but is a pain to maintain and scale. These updates in WordPress 6.9, especially around Gutenberg DataViews, are about developer experience and long-term stability. They provide a standardized, robust, and performant way to handle complex data and interfaces within the block editor. This means less time debugging bespoke solutions, faster development cycles, and happier clients because their admin areas actually work the way they expect.

If you’re still rolling your own custom data management solutions with old-school meta boxes or overly complex custom fields, you’re doing it wrong. The future is in embracing these new APIs. They simplify everything from basic form fields to complex data tables with filtering and pagination. This isn’t just about making things pretty; it’s about building scalable, maintainable WordPress applications that stand the test of time and future core updates.

Look, this stuff gets complicated fast. If you’re tired of debugging someone else’s mess and just want your site to work, drop my team a line. We’ve probably seen it before.
