Dementor Blocks

Audit and convert Elementor-built pages into native WordPress blocks. Works without Elementor active — Dementor Blocks reads stored Elementor data straight from post meta, scores each page's migration readiness, and converts supported Elementor structures into portable core blocks.

Status: v0.1 · early development · targets the upcoming WordPress 7.0 release and PHP 8.4.

What it does

• Scans standard WordPress pages for stored Elementor data (_elementor_data post meta).
• Audits each page with a 0–100 readiness score and a Ready / Review Needed / Manual Rebuild level, plus warnings for unsupported widgets and CSS dependencies.
• Converts sections, containers, columns, headings, text, images, buttons, spacers, separators, lists, embeds, and shortcodes into native blocks (core/group, core/columns, core/heading, core/paragraph, core/image, core/buttons, core/embed, etc.).
• Preserves layout nesting correctly, including Elementor flex containers and inner sections.
• Falls back gracefully for unsupported widgets — they become core/html blocks tagged with the original widget name, with nested children preserved instead of dropped.
• Style modes: none (structure only), inline (block-level style attrs), or css (per-page stylesheet stored in post meta and enqueued on the front end).
• Two destinations: duplicate to a new draft, or replace the original (with a WP revision + meta backup taken automatically before the overwrite).

Requirements

• WordPress 7.0 or later
• PHP 8.4 or later
• Administrator capability (manage_options) to access the audit/convert UI

Elementor does not need to be active — Dementor Blocks reads Elementor's stored post meta directly.

Installation

1. Clone or download this repository into wp-content/plugins/dementor-blocks/.
2. Run the build step (see Development below) so the React admin bundle is available in build/.
3. Activate Dementor Blocks from the Plugins screen.
4. Open Tools → Dementor Blocks to start auditing.

Usage

1. Audit. From the admin screen, run an audit on one or many pages. Each row reports a readiness score, level, widget breakdown, and warnings.
2. Choose a style mode. none strips visual styling, inline writes per-block style attrs, css emits a scoped stylesheet stored per-page.
3. Convert. Pick either:
   • Duplicate — a new draft page is created with the converted block content (and excerpt, parent, menu order, featured image, page template all copied over).
   • Replace — the original page's content is overwritten. A WordPress revision is taken first, and the prior content is stashed to _dementor_blocks_pre_replace_backup for one-click recovery.
4. Review. Open the resulting page in Gutenberg, check the conversion warnings, and clean up any unsupported widgets flagged with core/html fallbacks.

REST API

All routes are gated by manage_options and live under the dementor-blocks/v1 namespace:

/pages accepts page and per_page (max 200) and returns X-WP-Total / X-WP-TotalPages headers, matching core REST conventions.

Extensibility

Hooks are provided so extensions can plug in without forking:

// Register additional widget types as natively supported.
add_filter( 'dementor_blocks/supported_widgets', function ( $widgets ) {
    $widgets[] = 'accordion';
    return $widgets;
} );

// Convert a custom widget yourself by returning a block array (serialize_blocks() shape).
add_filter( 'dementor_blocks/convert_widget', function ( $block, $widget, $settings, $children, $ctx ) {
    if ( $widget !== 'accordion' ) {
        return $block;
    }
    return [
        'blockName'    => 'core/details',
        'attrs'        => [],
        'innerBlocks'  => [],
        'innerHTML'    => '<details>…</details>',
        'innerContent' => [ '<details>…</details>' ],
    ];
}, 10, 5 );

// Map additional Elementor settings onto block attrs.
add_filter( 'dementor_blocks/block_attrs', function ( $attrs, $settings, $ctx ) {
    if ( ! empty( $settings['border_radius']['size'] ) ) {
        $attrs['style']['border']['radius'] = $settings['border_radius']['size'] . 'px';
    }
    return $attrs;
}, 10, 3 );

// Route conversion failures to your logger of choice.
add_action( 'dementor_blocks/conversion_failed', function ( $post_id, $warnings, $result ) {
    error_log( "Dementor Blocks: conversion failed for {$post_id} — " . implode( '; ', $warnings ) );
}, 10, 3 );

Development

# install PHP + JS deps
composer install
npm install

# build the React admin bundle
npm run build

# watch mode
npm run start

Tests

The PHP test suite needs WordPress core checked out and a test database. One-time setup on macOS (with Homebrew installed):

brew install mariadb subversion
brew services start mariadb
mariadb -u "$USER" -e "CREATE DATABASE IF NOT EXISTS wordpress_test;"
bash bin/install-wp-tests.sh wordpress_test "$USER" '' localhost latest true

After that, composer test will run the suite. Subsequent runs are fast — only the first invocation downloads WordPress and the test files.
