Welcome to the block editor!

To leave here with a clear understanding of how to extend the block editor for a better WordPress experience.

Today's goal:

Learn Javascript

Learn UX

Widgets

[shortcodes]

Admin Pages

Customizer

Third party apps

User experience in WordPress has never been as important as it is today

Learn design & UX, the anatomy of the editor and  core UX patterns

The Anatomy of the Block Editor

We must grasp the block editor design patterns...

...to build remarkable blocks experiences. 

Block Content

Block Settings Sidebar

Block Toolbar

Primary interface for adding & manipulating content

Two main patterns: Placeholders & Contextual Controls

Most intuitive

Block

Content Area:

Block-level controls consisting of 100% necessary commonly-used actions

Block Toolbar

Must be:

1. Contextual

2. Fitting within the current UI

3. Necessary for managing a block

Shows advanced settings and controls for the currently selected block.

Settings Sidebar

Must be:

1. Contextual

2. Not necessary for the basic block operation

Extending blocks with Style Variations

Register Block Styles (Server)

Function: register_block_style()

1. Receives the name of the block as the first argument and an array describing properties of the style as the second argument

2. Include inline_style or style_handle (inline styles or stylesheet of styles) 

<?php 

register_block_style(
    'core/button',
    array(
        'name'         => '3d',
        'label'        => __( '3D' ),
        'inline_style' => '.wp-block-button.is-style-3d .wp-block-button__link { box-shadow: inset 0 -3px 0 0 rgba(0,0,0,0.25); }',
    )
);

Adding block styles (PHP)

Yes, it's that simple

/**
 * WordPress dependencies
 */
import { __ } from '@wordpress/i18n';
import { registerBlockStyle } from '@wordpress/blocks';

wp.blocks.registerBlockStyle( 'core/button', {
    name: '3d',
    label: __( '3D', 'textdomain' ),
    isDefault: false,
} );

Adding block styles (ESNext)

Not too shabby :) 

function blocktalk_enqueue() {
    wp_enqueue_script(
        'blocktalk-script',
        plugins_url( 'blocktalk.js', __FILE__ ),
        array( 'wp-blocks', 'wp-dom-ready', 'wp-edit-post' ),
        filemtime( plugin_dir_path( __FILE__ ) . '/blocktalk.js' )
    );
}
add_action( 'enqueue_block_editor_assets', 'blocktalk_enqueue' );

Adding block styles (JS)

wp.domReady( function() {
	wp.blocks.registerBlockStyle( 'core/button', [
		{
			name: '3d',
			label: '3D',
			isDefault: true,
		}
	]);
} );

Altered Reality

20+ image filters for the Image block

WordPress Plugin

CoBlocks

Checkbox style applied to the core List block

WordPress Plugin

Function: unregister_block_style()

Unregister Block Styles

2. Registered name of the block, and the name of the style.

1. Allows unregistering a block style previously registered on the server using register_block_style()

3. Only works for styles registered server-side

function blocktalk_enqueue() {
    wp_enqueue_script(
        'blocktalk-script',
        plugins_url( 'blocktalk.js', __FILE__ ),
        array( 'wp-blocks', 'wp-dom-ready', 'wp-edit-post' ),
        filemtime( plugin_dir_path( __FILE__ ) . '/blocktalk.js' )
    );
}
add_action( 'enqueue_block_editor_assets', 'blocktalk_enqueue' );

Unregister block styles (JS)

wp.domReady( function() {
    wp.blocks.unregisterBlockStyle( 'core/quote', 'large' );
} );

Extending blocks with Block Variations

Register Block Variations

Javascript: registerBlockVariation()

Receives the name of the block, title of the variant, description, icon, attributes, innerBlocks and example (basically the same as registering a block)

import { Path, SVG } from '@wordpress/components';
import { __ } from '@wordpress/i18n';
import { registerBlockVariation } from '@wordpress/blocks';

registerBlockVariation( 'coblocks/form', {
	name: 'event-registration',
	label: __( 'Event registration', 'coblocks' ),
	icon: '',
	innerBlocks: [
		[ 'coblocks/field-name', { label: __( 'Full name', 'textdomain' ), hasLastName: true } ],
		[ 'coblocks/field-email', { required: false } ],
		[ 'coblocks/field-textarea', { label: __( 'Dietary needs?', 'textdomain' ), required: true } ],
		[ 'coblocks/field-checkbox', { label: __( 'I will follow the Code of Conduct', 'textdomain' ), options: [ __( 'Yes', 'textdomain' ) ] } ],
	],
	submitButtonText: __( 'Register', 'textdomain' ),
	scope: [ 'block' ],
} );

Adding block variations (ESNext)

Similar to registering blocks

wp.domReady( function() {

	wp.blocks.registerBlockVariation( 'coblocks/form', {
		name: 'event-registration',
		label: 'Event registration',
		icon: '',
		innerBlocks: [
			[ 'coblocks/field-name', { label: 'Full name', hasLastName: true } ],
			[ 'coblocks/field-email', { required: false } ],
			[ 'coblocks/field-textarea', { label: 'Dietary needs?', required: true } ],
			[ 'coblocks/field-checkbox', { label: 'I will follow the Code of Conduct', options: [ 'Yes' ] } ],
		],
		submitButtonText: 'Register',
		scope: [ 'block' ],
	} );
} );

Adding block variations (JS)

Don't forget to enqueue the script

Extending blocks with Block Patterns

Block Patterns

Combinations of blocks you can create, and share, to help folks make rich, unique site layouts quicker

Registering Block Patterns

Receives two arguments: A title to name the pattern, and raw HTML content. 

function blocktalk_register_block_patterns() {
	if ( function_exists( 'register_pattern' ) ) {
		register_pattern(
			'blocktalk/highlight-feature',
			array(
				'title'   => __( 'Highlight feature', 'textdomain' ),
				'content' => "<!-- wp:group {\"backgroundColor\":\"primary\",\"align\":\"full\"} -->\n<div class=\"wp-block-group alignfull has-primary-background-color has-background\"><div class=\"wp-block-group__inner-container\"><!-- wp:paragraph {\"customFontSize\":45,\"lineHeight\":1.56} -->\n<p style=\"font-size:45px;line-height:1.56\" class=\"has-custom-lineheight\">Curabitur blandit tempus port titor um sociis lorem.</p>\n<!-- /wp:paragraph -->\n\n<!-- wp:columns -->\n<div class=\"wp-block-columns\"><!-- wp:column -->\n<div class=\"wp-block-column\"><!-- wp:paragraph -->\n<p>Morbi leo risus, porta ac consectetur ac, vestibulum at eros.

Nullam quis risus eget urna mollis ornare vel eu leo.</p>\n<!-- /wp:paragraph --></div>\n<!-- /wp:column --></div>\n<!-- /wp:columns --></div></div>\n<!-- /wp:group -->",
			)
		);
	}
}
add_action( 'init', 'blocktalk_register_block_patterns' );

}

.has-large-font-size {
	font-size: 36px;
}

Adding Font Size Classes

In the theme's stylesheet

Editor Gradient Presets

1. Themes can register their own gradients to be used throughout the editor, for blocks that support gradeints

2. Themes must provide relevant gradient classes

<?php 
function blocktalk_setup_theme() {
    add_theme_support( 'editor-gradient-presets',
    array(
        array(
            'name'     => __( 'Vivid cyan blue to vivid purple', 'textdomain' ),
            'gradient' => 'linear-gradient(135deg,rgba(6,147,227,1) 0%,rgb(155,81,224) 100%)',

In the theme's functions.php file

.has-vivid-cyan-blue-to-vivid-purple-gradient-background {
    background: linear-gradient(135deg,rgba(6,147,227,1) 0%,rgb(155,81,224) 100%);
}

Adding Gradient Classes

In the theme's stylesheet

Wide and Full Alignments

1. Themes can opt into supporting the editor's new wide and fullwidth alignment options

2. add_theme_support( 'align-wide' );

Dark mode

1. Themes can opt into a suite of dark-first editor styling
