Flinkform is a form builder that lives entirely inside the WordPress Block Editor. Forms are composed from native blocks (<code>block.json</code> v3), styled through <code>theme.json</code> design tokens, and powered by the Interactivity API — no separate admin UI, no shortcodes, no jQuery.
<h4>How it works</h4>
<ul>
<li>Block Editor native — forms are built with <code>block.json</code> and the Interactivity API, directly inside the editor</li>
<li>theme.json styling — forms inherit your theme’s typography, colours and spacing automatically</li>
<li>Modern stack — WordPress 6.5+, PHP 8.1+, no jQuery, frontend JS under 15 KB gzipped</li>
<li>Multi-step forms — split long forms into steps with a Page Break block, included in the free core</li>
<li>Conditional logic — show/hide fields based on user input, included in the free core</li>
<li>WCAG 2.1 AA — full keyboard navigation, screen-reader compatible, aria-live announcements</li>
<li>Privacy by design — no external services, no tracking cookies, no IP tracking — everything stays on your server</li>
</ul>
<h4>Features (free core)</h4>
Form building 
* 13 field types: Text, Email, Textarea, Number, Date, URL, Phone, Select, Radio, Checkbox, Toggle, Hidden, Section Heading 
* Dedicated Consent field for privacy-policy agreement 
* Multi-step forms with Page Break block, per-step validation and progress indicator (bar, dots or numbers) 
* Conditional logic — show/hide fields, skip steps, gate the submit button 
* Two-column layout with per-field full-width override
Styling 
* Automatic theme.json inheritance (colours, typography, spacing, border radius) 
* Style panel: primary colour, field style (bordered/soft/underline/minimal), label position (above/beside/floating/placeholder), submit button style (fill/outline/ghost)
Notifications 
* Admin notification email on every submission (configurable recipient, merge tags) 
* Optional confirmation email to the submitter 
* Sends through your site’s standard WordPress mail (<code>wp_mail</code>)
Spam protection 
* Always-on honeypot + signed time-based check (zero configuration) 
* Built-in proof-of-work challenge with accessible math fallback for visitors without JavaScript 
* No external service, no API keys, no tracking cookies, 100% GDPR-friendly
After submission 
* Success message or redirect to a custom thank-you URL (with open-redirect protection) 
* Optional submission ID and form ID query parameters for conversion tracking (GA4, Meta Pixel, Plausible, etc.)
Admin 
* Submissions list with search, filter by form, sort, bulk actions 
* Single-submission detail view with all field labels and values 
* Mark as read/unread 
* Per-form data retention with automatic daily purge
<h3>Privacy</h3>
Flinkform is built with privacy by default. Here is what the free core does and does not do:
What the free core stores: 
* Form submissions (the field values visitors enter) in a dedicated database table (<code>{prefix}flinkform_submissions</code>)
What the free core does NOT do: 
* It stores no IP addresses and no browser user-agent strings 
* It sets no tracking, analytics or marketing cookies. Flinkform sets exactly one strictly-necessary cookie — <code>flinkform_flash</code> (lifetime ~60 seconds, httpOnly) — and only when a form submission fails validation, to carry the error message and the visitor’s input across the page reload. Successful submissions set no cookie at all 
* It contacts no external service
Data retention: 
* By default, submissions are retained until you delete them. To comply with the storage-limitation principle (GDPR Art. 5), set a per-form retention period (Form block → Data Retention) and Flinkform deletes older submissions automatically each day 
* Individual submissions can be deleted from the admin submissions screen at any time
Data deletion: 
* All free-core data (the submissions table) is permanently removed when the plugin is uninstalled through the WordPress admin 
* Flinkform integrates with WordPress’s privacy tools (Tools > Export Personal Data / Erase Personal Data) to support data-subject access and erasure requests
<h3>Source Code</h3>
The complete, uncompiled source code (including the <code>src/</code> directory with the 
unminified JavaScript/CSS that compiles into <code>build/</code>) is publicly available at: 
https://github.com/dennisbuchwald/Flinkform
Build instructions (Node.js 18+ and npm required): 
1. Clone the repository: <code>git clone https://github.com/dennisbuchwald/Flinkform.git</code> 
2. Install dependencies: <code>npm install</code> 
3. Build the compiled assets into <code>build/</code>: <code>npm run build</code>
The build is powered by <code>@wordpress/scripts</code> (webpack). The <code>src/</code> sources are 
excluded from the distributed plugin zip to keep it small; this repository is 
the canonical, reviewable source.

Flinkform – Forms for the Block Editor

Block-native form builder for the WordPress Block Editor — theme.json styling, multi-step forms, conditional logic, Interactivity API.

Block Logic adds a “Block Logic” field to the “Advanced” section of the block editor (i.e Gutenberg), that lets you show or hide any block based on conditions. You can use WordPress’ <a href="https://codex.wordpress.org/Conditional_Tags" rel="nofollow ugc">Conditional Tags</a> or any general PHP code.
<h3>Show or hide blocks based on</h3>
<ul>
<li>User role</li>
<li>User login status</li>
<li>Post status</li>
<li>Date and time</li>
<li>The result of a custom PHP function</li>
</ul>
<h3>Features</h3>
<ul>
<li>Show or hide any block using conditions</li>
<li>Combine conditions with “and” or “or” operators. See FAQ Writing Logic Code</li>
<li>Full flexibility: use any condition you want (you can extend base functionality with filters)</li>
</ul>
<h3>Limitations</h3>
Does not work with the Classic Block, Widget Block or Widget Area Block [‘core/freeform’, ‘core/legacy-widget’, ‘core/widget-area’], as the those blocks do not support block attributes. Does also not work with the HTML Block [‘core/html’] inside the Widget Screen, as this one also does not support block attributes there.
<h3>Configuration</h3>
Just activate the plugin. The “Block Logic” textbox will then appear in the “Advanced” section of the Gutenberg editor.
<h3>Breaking changes since 2.0.0</h3>
Since version 2.0.0 the code does not get eval’d directly, but there is a whitelist of allowed functions that can be extended via a filter.
<h3>Upgrade Notice</h3>
When upgrading to version 2.x you will need to update your logic. No <code>return</code> is allowed anymore and no semicolons in code as only expressions are evaluated. See FAQ Section Writing Logic Code.

Block Logic – Full Block Display Control

Works just like widget logic. Excellent plugin and easy to use.

Work With New WordPress Theme Editor
