Survival Guide for a PHP Developer

- Matt Mullenweg, State of the Word 2015

Damn,
that's HARD...

How to survive in Gutenberg world
as a PHP developer

Option 1. Give Up

Just learn the damn JavaScript

It's not that hard...

 

create-guten-block by Ahmad Awais

 

a zero configuration dev-toolkit (#0CJS) to develop WordPress Gutenberg blocks in a matter of minutes without configuring React, webpack, ES6/7/8/Next, ESLint, Babel, etc.

 

npx create-guten-block my-block
cd my-block
npm start

Option 2. Collect

Use block collection plugins

There is a collection of them out there, already:

And many many more...

Option 3. Use ACF, Luke

No, really.

Well, a block builder plugin. There is a bunch of those as well.

ACF

Pros

- Big user base

- Most field types

 

Cons
- Most code involved

- Only in PRO version

Block Lab

Pros

- Gutenberg - specific


Cons

- Least block options

- No way to use purely via code

Lazy Blocks

Pros

- Gutenberg - specific

- Full control via UI
- Full control via code

 

Cons
- Missing field types

- Limited conditional controls

Option 4. PHP!

Yes, we can!

Not an option directly in WordPress Core, but we can use some tools:

GutenFactory

A piece of history.

 

Built during Contributors Day at WordCamp Norrköping 2018

 

An early attempt on purely PHP-based Gutenberg block creator

Sample

add_filter( 'gutenfactory_blocks', 'my_awesome_block' );
function my_awesome_block( $blocks ) {
  $blocks['arunas/my_awesome_block'] = [
    'name'          => 'My Awesome Block',
    'category'      => 'common',
    'style'         => plugins_url( 'my-awesome-block.css', __FILE__ ),
    'editor_style'  => plugins_url( 'my-awesome-block-editor.css', __FILE__ ),
    'callback'      => 'my_awesome_block_render',
    'fields'        => [
     // define the fields here.
    ]
  ];
  return $blocks;
}

Advanced Custom Fields

PRO version, 5.8 or higher

 

acf_register_block_type()

 

Fields have to be built via UI, but can then be loaded via JSON files

Sample

add_action('acf/init', 'my_register_blocks');
function my_register_blocks() {
    // check function exists.
    if( function_exists('acf_register_block_type') ) {
        // Register a testimonial block.
        acf_register_block_type(array(
            'name'              => 'testimonial',
            'title'             => __('Testimonial'),
            'description'       => __('A custom testimonial block.'),
            'render_template'   => 'template-parts/blocks/testimonial/testimonial.php',
            'category'          => 'formatting',
        ));
    }
}

ACF Builder

A PHP Library to easily build ACF fields via code

 

https://github.com/StoutLogic/acf-builder

Sample

$banner = new StoutLogic\AcfBuilder\FieldsBuilder('banner');
$banner
    ->addText('title')
    ->addWysiwyg('content')
    ->addImage('background_image')
    ->setLocation('block', '==', 'acf/testimonial')
        ->or('block', '==', 'acf/anotherone');

add_action('acf/init', function() use ($banner) {
   acf_add_local_field_group($banner->build());
});

Lazy Blocks

a Gutenberg blocks visual constructor

 

The ACF of Gutenberg age

 

UI based, but has an option to export a PHP snippet

 

 

Sample

if ( function_exists( 'lazyblocks' ) ) :
    lazyblocks()->add_block( array(
        'title' => 'Custom block',
        'slug' => 'lazyblock/custom-block',
        'supports' => array(
            'html' => false,
            'multiple' => true,
        ),
        'controls' => array(
        	// define fields
        ),
        'code' => array(
        	// editor/frontend templates or callbacks, assets
        ),
    ) );
endif;

Lazy Blocks Builder

PHP library to simplify block declarations

 

https://github.com/ideag/lazy-blocks-builder

 

Sample

if ( function_exists( 'lazyblocks' ) ) :

    $block = new Lazy_Blocks_Builder( 'Custom Block' );
    $block
      ->setOption( 'description', 'A sample block for WordSesh' );
    $block
      ->addText( 'heading' )
        ->setDefault( 'Big heading here' )
        ->setRequired()
      ->addRichTextEditor( 'copy' )
      	->setDefault( 'Some lorem ipsum here as a placeholder')
    ;
    $block->setSingleCallback( function( $data ) { /* ... */ } );
    $block->build();

endif;

Missing Pieces

A utility-first CSS framework

 

Define everything via CSS classes

 

Works well without any build process

 

Works amazingly if you do add a build step

A tiny JS declarative and reactive JS framework

 

You get to keep your DOM, and sprinkle in behaviour as you see fit.

 

Can be loaded from CDN, without building or bundling.

<div x-data="{ open: false }">
    <button @click="open = true">
    	Open Dropdown
    </button>
    <ul
        x-show="open"
        @click.away="open = false"
    >
        Dropdown Body
    </ul>
</div>
