README

A reusable Table of Contents package for Statamic that extracts headings from HTML, Markdown, and Bard content, generates stable anchors, and optionally injects heading IDs into rendered HTML.

Requirements

• PHP 8.3+
• Laravel 12
• Statamic 6

Installation

composer require bit-mx/statamic-toc

Publish Configuration

php artisan vendor:publish --tag=statamic-toc-config

This publishes config/statamic-toc.php.

Configuration

return [
    'min_level' => 1,
    'max_level' => 6,
    'preserve_existing_ids' => true,
    'default_source' => 'html',
    'default_tree' => true,

    'cache' => [
        'enabled' => false,
        'ttl' => 600,
        'store' => null,
        'prefix' => 'statamic_toc',
    ],
];

Key Options

• min_level, max_level: Heading level range included in TOC.
• preserve_existing_ids: Keep existing heading IDs when injecting anchors.
• cache.enabled: Enable caching for tag output.
• cache.ttl: Cache lifetime in seconds.

Usage

Blade Tag Compatibility (<s:toc>)

This package is compatible with Statamic Blade tag usage like:

<s:toc :content="$content" :is_flat="false" depth="3" from="h1">
    @isset($toc_id)
        <a href="#{{ $toc_id }}">{{ $toc_title }}</a>

        @if($has_children)
            @foreach($children as $child)
                <a href="#{{ $child['toc_id'] }}">{{ $child['toc_title'] }}</a>
            @endforeach
        @endif
    @endisset
</s:toc>

Supported legacy params:

• content
• field (default: article)
• depth (default: 3)
• from (default: h1)
• is_flat (default: false)

Legacy output keys are provided for drop-in compatibility:

• toc_title
• toc_id
• toc_level
• children
• has_children
• total_children
• total_results
• no_results

Tag Usage (Antlers / Blade context)

Use the toc tag to extract TOC items.

{{ toc:items source="html" :content="content" min_level="2" max_level="4" }}
  <li><a href="#{{ id }}">{{ text }}</a></li>
{{ /toc:items }}

Parameters:

• source: html, markdown, or bard.
• content: The input payload to parse.
• min_level / max_level: Optional level limits.
• tree: true/false to return hierarchical or flat output.

Modifier Usage

Inject heading IDs into rendered HTML:

{{ content | toc }}

Optional params:

{{ content | toc:2:4:true }}

Meaning:

1. min level
2. max level
3. preserve existing IDs

Service / Facade Usage (PHP)

use BitMx\StatamicToc\Facades\Toc;

$items = Toc::extractAsArray('markdown', $markdown, 1, 6, true);

Or via DI:

use BitMx\StatamicToc\Toc\TocService;

public function show(TocService $tocService): array
{
    return $tocService->extractAsArray('html', $html, 2, 4, true);
}

Output Shape

Each item includes:

• text
• level
• id
• url (for example, #installation)
• children (when tree=true)

Bard Integration Notes

The Bard extractor walks nested node structures and set values, so headings inside nested/complex Bard content are included.

Caching

When cache.enabled=true, tag results are cached using a key that includes source, content, level range, and tree mode.

Migration from In-App TOC Logic

If you already have custom parser/tag/modifier classes in your project:

1. Install this package.
2. Replace custom TOC tag calls with package tag usage.
3. Replace custom heading-id injection with | toc modifier.
4. Keep your front-end template markup, only swap data source.
5. Remove legacy TOC classes after parity verification.

Troubleshooting

IDs are not added to headings

• Ensure content passed to modifier is rendered HTML.
• Confirm heading levels are within configured min/max.

Duplicate anchors

• Duplicate heading text is expected to produce suffixes (-2, -3, ...).

Missing Bard headings

• Verify the field content passed to source bard is raw Bard data (array structure).

Cache not updating

• Disable cache during development.
• Check cache store and TTL settings.

Testing

composer test
