Booking / Appointment for WordPress

<?php
// Drop into a PHP page. Receives a form POST and proxies it to splitforms.com.
// Useful when you want to add server-side validation or rate limiting.

if ($_SERVER['REQUEST_METHOD'] === 'POST') {
    // sf_sid: passing it on lets partial leads close once the visitor
    // submits. It only exists if the page with your form also has
    //   <form data-sf-key="YOUR_ACCESS_KEY" ...>   (this proxy adds access_key, so the form has none)
    //   <script src="https://splitforms.com/embed.js" async></script>
    // — embed.js then adds the hidden sf_sid input. Harmless without it.
