slashbooking

<p><strong>SlashBooking</strong> turns any WordPress page into a self-service appointment funnel. A visitor picks a service, sees the available slots in real time, and books in under a minute. You receive an email alert and confirm or decline in one click — no need to log in to WordPress, no third-party SaaS, no recurring fees.</p>
<p>It is a self-hosted scheduling tool: your data stays in your WordPress database.</p>
<h4>Main features</h4>
<ul>
<li><strong>Public booking form via shortcode</strong> — A single <code>[slashbooking]</code> in any page. Multiple services, date picker, real-time slots, customer form, fully responsive.</li>
<li><strong>One-click email confirmation</strong> — Every request arrives with two buttons, <em>Confirm</em> and <em>Decline</em>. No WordPress login required. The action links are signed with HMAC-SHA256 and cannot be forged.</li>
<li><strong>Smart buffers around appointments</strong> — Configure padding (travel, prep) between appointments. Applied automatically.</li>
<li><strong>Multi-slot opening hours</strong> — Monday 9–12 + 14–18, Tuesday morning only, Wednesday off… Each day and each service is configured independently.</li>
<li><strong>Transactional emails with .ics</strong> — Confirmation, decline and acknowledgement emails, each with an automatic <code>.ics</code> attachment so the customer adds the appointment to their calendar in one click.</li>
<li><strong>Built-in GDPR compliance</strong> — Explicit consent before submission, WP_Privacy exporters/erasers, configurable retention, automatic anonymisation.</li>
<li><strong>Built-in anti-spam</strong> — Honeypot and per-IP rate limiting, with no third-party service and no external request.</li>
</ul>
<h4>Who it is for</h4>
<ul>
<li>Freelancers and small businesses who want a self-hosted scheduling page</li>
<li>Agencies packaging a website with a booking funnel</li>
<li>Any business where “book a slot” opens the customer journey</li>
</ul>
<h3>External services</h3>
<p>This plugin is fully self-contained. It makes no calls to any external or third-party service and sends no data off your site — every request is handled on your own WordPress installation.</p>
<h3>Source code and build</h3>
<p>The full, human-readable source code is public and maintained at:</p>
<p>https://github.com/ArchSeraphin/slashbooking-lite</p>
<p>The PHP runs unmodified from <code>src/</code>. The admin interface bundle<br />
(<code>assets/dist/index.jsx.js</code> and <code>.css</code>) is compiled from the React/SCSS sources<br />
in <code>src/Admin/react-app/src/</code>, which ship inside the plugin ZIP as well.</p>
<p>To regenerate the compiled admin assets:</p>
<pre><code>npm install
npm run build   (uses @wordpress/scripts — webpack/Babel; outputs to assets/dist/)
</code></pre>
<p>The Composer autoloader in <code>vendor/</code> is generated with <code>composer install --no-dev</code>.</p>
