# Landing Page Generator - Project Overview

## Project Goal
Create a **fully automated Landing Page Generator**.

The entrepreneur fills a 5-step wizard with business information. The system then automatically:
- Generates a complete, professional landing page
- Stores leads in a MySQL database
- Sends the lead a confirmation email with the attached Lead Magnet PDF
- Allows each owner to view only their own leads via a login dashboard

## Tech Stack Used
Backend,"PHP 8+ (pure PHP, no framework)","All logic (wizard, generation, AJAX, OpenAI calls)"
Database,MySQL,Stores all leads (leads table)
Frontend,HTML5 + Tailwind CSS (via CDN) + Vanilla JavaScript,"Modern, responsive design with no build step"
Templating,Simple string replacement (str_replace),On index-template.html (not Twig)
AI / LLM,OpenAI API (gpt-4o-mini),Content generation + color extraction + prompt chaining
Hosting,Namecheap Shared Hosting + cPanel,Standard PHP/MySQL environment
File System,Dynamic folder creation (mkdir),Each landing page gets its own folder under /lp/
Email,PHP mail() with multipart MIME,Sends confirmation email + PDF attachment
Session,PHP $_SESSION,Maintains wizard data across steps
The code will be hosted on Namecheap Shared Hosting.

## Folder Structure
public_html/
├── generator.php                 # Main 5-step wizard
├── config.php                    # Database + OpenAI configuration
├── process.php                   # Handles form submission, DB insert, email with PDF
├── templates/
│   └── index-template.html       # Master template used to generate each landing page
├── lp/                           # Folder where all generated landing pages are created
│   └── (auto-created subfolders like "metaxyz-20260515-1432/")
└── (optional) lead-magnets/      # Can be used to store PDFs if needed


## Current Features
- 5-step wizard with progress bar
- "Generate Suggestion" buttons using OpenAI (gpt-4o-mini) with prompt chaining
- "Extract Colors" button that analyzes a reference website URL
- Custom domain support (A record + CNAME instructions shown on success)
- Automatic folder creation and deployment of each landing page
- Lead storage + email with PDF attachment

## Database Schema (SQL)

CREATE TABLE IF NOT EXISTS leads (
    id INT AUTO_INCREMENT PRIMARY KEY,
    timestamp DATETIME DEFAULT CURRENT_TIMESTAMP,
    campaign VARCHAR(100) NOT NULL,
    name VARCHAR(255),
    email VARCHAR(255),
    interest TEXT,
    INDEX idx_campaign (campaign)
);

## Current Problems (as reported by user)
- The wizard sometimes shows blank steps after Step 1
- "Generate Suggestion" and "Extract Colors" sometimes return HTML code instead of clean text
- Some steps appear empty

## Task for Claude

Please analyze the current system and provide an improved, clean, robust version of the Landing Page Generator.

Focus on:
- Making the wizard reliable (all steps must show their input fields correctly)
- Ensuring AJAX calls for "Generate Suggestion" and "Extract Colors" always return clean text/JSON
- Improving overall code structure, error handling, and maintainability
- Adding any small improvements you consider valuable (security, UX, performance, etc.)

The original`generator.php`, `config.php`, `process.php`, `templates/index-template.html`files are now in the folder c:/XAMPP/htdocs/generator
