Manual Installation

1. Download the plugin
2. Upload to your /wp-content/plugins/ directory
3. Activate the plugin through the 'Plugins' menu in WordPress

Usage

Once activated, you'll have a new "EditorJS" field type available in ACF field groups.

Field Settings

• Default Value: Set the default content for new posts
• Placeholder Text: Placeholder shown in empty editor
• Available Tools: Choose which Editor.js tools to enable
• Minimum Height: Set the minimum height of the editor

Retrieving Data

The field returns Editor.js data as an array:

$content = get_field('editorjs_field');

// Returns array like:
// [
//     'time' => 1234567890,
//     'blocks' => [
//         [
//             'type' => 'paragraph',
//             'data' => [
//                 'text' => 'Hello world!'
//             ]
//         ]
//     ],
//     'version' => '2.22.0'
// ]

Rendering Content

You'll need to create your own renderer for the Editor.js data. Example:

function render_editorjs_content($data) {
    if (empty($data['blocks'])) {
        return '';
    }
    
    $html = '';
    foreach ($data['blocks'] as $block) {
        switch ($block['type']) {
            case 'paragraph':
                $html .= '<p>' . esc_html($block['data']['text']) . '</p>';
                break;
            case 'header':
                $level = $block['data']['level'];
                $html .= '<h' . $level . '>' . esc_html($block['data']['text']) . '</h' . $level . '>';
                break;
            // Add more block types as needed
        }
    }
    
    return $html;
}

Development

Building Assets

The plugin includes EditorJS and its tools locally for better control and performance:

1. Install dependencies: npm install
2. Build all assets: npm run build
3. For development with watch mode: npm run dev

Build Process

• npm run build - Builds the complete bundle
• npm run dev - Builds and watches for changes
• npm run clean - Removes the dist directory

The build process creates:

• dist/acf-editorjs.iife.js - Complete bundle with EditorJS core, tools, and field initialization (~357KB)
