User is working on a Fossetts Circus ticket booking system with Stripe payment integration and PHP-based backend.

Assistant

Here’s a detailed step-by-step breakdown and understanding of the provided codebase, which is a comprehensive ticket booking system for **Fossetts Circus** using **PHP**, **Stripe**, **AJAX**, and custom HTML forms:

—

## 🧠 **High-Level Overview**
This script:
– Loads event data.
– Renders the booking form dynamically.
– Handles payments via Stripe.
– Manages vouchers.
– Sends confirmation emails.
– Saves the order to the database.
– Works with multiple formats: classic and AJAX-based.

—

## 🧩 **1. Initialization & Utilities**

### Error Handling Setup

error_reporting(E_ALL);
ini_set('display_errors', 1);
ini_set('log_errors', 1);
ini_set('error_log', 'includes/php-error.log');
ob_start();

Enables full error reporting, logging to `includes/php-error.log`, and starts output buffering.

—

## 🔍 **2. Special GET Requests (debug, version check)**

### a. `/script.php?version_check`
Returns static JSON with version info.

### b. `/script.php?debug_ticket_processing`
Debugs ticket processing logic:
– Fetches event/ticket data.
– Compares seating area and ticket names (case-insensitive).

## ⚡ **4. AJAX Request Handling**

Only executed if `$_SERVER['HTTP_X_REQUESTED_WITH'] == 'xmlhttprequest'`.

### a. **Retrieve & Validate Event**
Fetches event data using posted `event_id` and `event_date_id`.

### b. **Ticket Price Calculation (New Structure)**
Loop over `$_POST` keys like `event_seat_ringside_adult`:
– Parse into seating area & ticket type.
– Match with ticket definitions.
– Sum up quantities & calculate total.

### c. **Voucher Handling**
Apply discounts based on code:
– Percentage or flat amount.

### d. **Stripe Payment Intent Creation**
Using **Stripe Connect** for platform fee:

StripePaymentIntent::create([
  'amount' => $amount_in_cents,
  'application_fee_amount' => $fee_in_cents,
  'stripe_account' => 'acct_1C7mK9IQtQgABICR'
])

### e. **Handle 3D Secure or Success**
– If `requires_action`: return `client_secret` for 3DS.
– If `succeeded`: process order, email, redirect.
– Otherwise: show error.

## 📄 **5. Legacy Form POST Handling (Non-AJAX)**

Fallback for classic form submission.

### a. **Validates Fields**
Ensures:
– Matching emails.
– Valid phone/date/seat.
– Ticket quantities > 0.

### b. **Calculate Price (Old structure)**
Separate pricing for:
– Full price = adult
– Reduced = child + senior

### c. **Stripe Payment (Classic Flow)**
Similar to AJAX.

### d. **Success Handling**
– Sends emails.
– Tracks via Mailchimp.
– Redirects to `success/?eid=…`.

## 🎨 **6. HTML + JS Frontend**

### a. Event Form Sections:
– Contact details
– Date/time + seat location
– Ticket quantities
– Payment fields (Stripe Elements)
– Voucher input
– Terms & Conditions

### b. JS Functions:
– `updateAvailableSeats()`: ensures seats

Implement Express Checkout using Google Wallet or Apple Pay or Revolute Pay if possible? All services are enabled and configured in stripe

Assistant

To implement **Express Checkout** using **Google Pay**, **Apple Pay**, and optionally **Revolut Pay** through **Stripe**, you can use **Stripe Payment Request Button (PRB)**, which supports all of them via a unified interface.

—

## ✅ Prerequisites

1. ✅ You’ve already enabled:
– Google Pay
– Apple Pay
– Revolut Pay *(available in supported countries via Stripe Checkout / PRB)*

2. ✅ You’re using **Stripe Elements** in your PHP site.

—

## ✅ Step-by-Step Integration (Express Checkout)

### 🔹 1. Update HTML: Add a container
Inside your form (above or beside card fields):

<div id="payment-request-button"></div>

—

### 🔹 2. Add Stripe JS Setup (already present)

This line is already in your script:

<script src="https://js.stripe.com/v3/"></script>

—

### 🔹 3. JavaScript: Initialize Payment Request Button

Add this *after* your existing Stripe Elements setup (`stripe = Stripe(…)`):

var paymentRequest = stripe.paymentRequest({
  country: 'IE', // or 'GB', 'US', etc.
  currency: 'eur',
  total: {
    label: 'Total',
    amount: Math.round(total * 100) // in cents
  },
  requestPayerName: true,
  requestPayerEmail: true,
});

var elements = stripe.elements();
var prButton = elements.create('paymentRequestButton', {
  paymentRequest: paymentRequest,
  style: {
    paymentRequestButton: {
      type: 'default',
      theme: 'light',
      height: '44px',
    },
  }
});

// Check if the Payment Request is available
paymentRequest.canMakePayment().then(function(result) {
  if (result) {
    prButton.mount('#payment-request-button');
  } else {
    document.getElementById('payment-request-button').style.display = 'none';
  }
});

—

### 🔹 4. Handle the Payment (JavaScript)

Add this:

paymentRequest.on('paymentmethod', async function(ev) {
  // Send paymentMethod.id to your server
  const response = await fetch('your-endpoint.php', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json'
    },
    body: JSON.stringify({
      payment_token: ev.paymentMethod.id,
      event_id: '...',         // fill as needed
      event_date_id: '...',    // fill as needed
      // ... any other fields
    })
  });

  const paymentResponse = await response.json();

  if (paymentResponse.success) {
    ev.complete('success');
    window.location.href = paymentResponse.redirect_url;
  } else {
    ev.complete('fail');
    alert(paymentResponse.message || 'Payment failed');
  }
});

—

### 🔹 5. PHP Backend Handling

Your existing backend already handles `payment_token` via:

if (isset($_POST['payment_token'])) {
  // create Stripe customer, attach payment method, create PaymentIntent...
}

**No backend change is needed**, unless you want to distinguish between card + PRB methods for logging.

—

## 💡 Notes

– ✅ Google Pay appears automatically on **Chrome (Android/Desktop)**.
– ✅ Apple Pay appears on **Safari + Apple devices**.
– ✅ Revolut Pay appears *if eligible and enabled on Stripe*.
– No special SDK is needed — **Stripe Elements handles it all**.

—

## 🚀 Result

You’ll get:
– Single-click payments via Apple Pay, Google Pay, Revolut Pay.
– Faster conversion.
– SCA/3DS handled automatically.

—

If you'd like:
– ✅ Working **demo** page template,
– ✅ Backend `fetch` handler for the PRB submission,
– ✅ Conditional display logic for desktop vs mobile,

just ask.
