Fast Blocks


Use the function add_fast_block to add a block to your theme in PHP. The Plugin automatically creates a interface for your block inside the editor.
Unlike the default block behaviour all blocks are rendered dynamically. This means changes inside the template are shown immediately without resaving the post or page.

Example Usage

Register your block:

$options = [
  'name'      => 'some-slug/block-name',
  // template from theme-directory
  'template'  => '/blocks/test.php',
  'settings'  => [
    // same settings as the original "wp.registerBlockType" without attributes.
    'title'   => 'Plugin Block',
  'fields'    => [
    // define attributes and inputs/labels etc. that are needed.
    'headline'  => [
      'label'    => 'My Label',
      'type'     => 'string',
      'input'      => 'text',
      'default'  => 'default string',
      'width' => 0.5, // optional for all fields except repeater
      // optional selector: useful fallback if dynamic rendering does not work. Also good for WP SEO PLugins.
      'selector' => 'h2',
    'text'  => [
      'label'    => 'Some Text',
      'type'     => 'string',
      'input'      => 'richText',
      'default'  => 'default string',
    'image'   => [
      'label'   => 'Label for the Upload Button',
      'type'    => 'object',
      'input'   => 'image',
      'default' => [
        'url'   => 'image.jpeg',
        'alt'   => 'Alternative Text',
        'sizes' => []
    'bgColor' => [
      'label'   => 'Background',
      'type'    => 'string',
      'default' => 'light',
      'input'     => 'select',
      'options' => [
        ['label' => 'light', 'value' => 'light'],
        ['label' => 'dark', 'value' => 'dark'],
    'someBool' => [
      // ...
      'type'    => 'boolean',
      'input'   => 'checkbox',
    'someArray' => [
      // ...
      'type' => 'array',
      'default' => [],
      'input' => 'repeater',
      'query' => [
        'subField1' => [
          'type' => 'string',
          'input' => 'text',
          'default' => 'default list item',
        'subField2' => [
          'type' => 'boolean',
          'input' => 'checkbox',
          'default' => true,

add_fast_block( $options );

Available inputs: text, richText, checkbox, toggle, select, image, url, email, date.
At the moment default values are mandatory.

Example usage inside template:

  <h2><?php $block->field('headline'); ?></h2>
  <img src="<?php echo $block->field_value('image')['url']; ?>">

For $block->field function sanitizing is done with wp_kses_post. If you need more complex sanitizing, use $block->field_value, sanitize on your own and echo the value afterwards.

Does it work with SEO Plugins?

To avoid problems with dynamic blocks and SEO analyzing Plugins, most fields are stored inside the block content the traditional way additionally. But this doesn’t mean it is 100% reliable.
