40Q Block handler

Handle custom Gutenberg blocks in a Roots/Radicle project

Installation

1. Install package with composer:

composer require 40q/block-handler

2. Find the providers array in config/app.php, and add the service provider class to the end of it.

'providers' => [
    // Other Service Providers...

    BlockHandler\Providers\BlockHandlerServiceProvider::class,
],

3. Use the package in BlocksServiceProvider.php

add_filter('render_block', function ($block_content, $block) {
    try {
        $factory = app(BlockHandler::class);
        $handlerClass = $factory->getHandler($block['blockName']);

        if ($handlerClass) {
            $handlerInstance = new $handlerClass();
            return $handlerInstance($block_content, $block);
        }
    } catch (\Exception $e) {
        error_log($e->getMessage());
    }

    return $block_content;
}, 10, 2);

4. Create a Blocks folder inside app and put your handlers inside.

Block handlers

The package will try to use each file inside app\Blocks as a block handler. In order for this to work as expected, make sure all classes follow the BlockHandler contract.

Blocks with their block handlers can be generated with the 40q cli tool:

40q codegen block

Example:

<?php

namespace App\Blocks;
use BlockHandler\Contracts\BlockHandler;

class Modal implements BlockHandler {
    public function __invoke($block_content, $block) {
        return view('blocks.modal', [
            'block' => $block,
            'blockContent' => $block_content,
            'buttonText' => $block['attrs']['buttonText'] ?? null,
            'heading' => $block['attrs']['heading'] ?? null,
        ]);
    }
}
