⚙️ Installation

1️⃣ Upload Plugin

Upload the ccavenue-payflow folder to /wp-content/plugins/ —or— Install the .zip via WordPress → Plugins → Add New → Upload Plugin

2️⃣ Activate Plugin

Activate CCAvenue PayFlow from the WordPress dashboard.

3️⃣ Add Required Constants

In your wp-config.php file, define your merchant credentials:

define('CCA_MERCHANT_ID', 'YOUR_MERCHANT_ID');
define('CCA_ACCESS_CODE', 'YOUR_ACCESS_CODE');
define('CCA_WORKING_KEY', 'YOUR_WORKING_KEY');
define('CCA_TEST_MODE', false); // Set to true for sandbox mode

4️⃣ Create Required Pages

Each shortcode automatically loads its matching template from includes/templates/.

🧩 Database Table

On activation, the plugin automatically creates:

wp_ccavenue_orders (
  id bigint(20) AUTO_INCREMENT,
  order_id varchar(50),
  name varchar(100),
  email varchar(100),
  amount decimal(10,2),
  status varchar(50),
  response_json text,
  created_at datetime DEFAULT CURRENT_TIMESTAMP,
  PRIMARY KEY (id)
)

This logs every initiated or completed payment.

🧠 Technical Workflow

1. User fills /pay/ form Data validated and stored in session → redirect to /pay-confirm/.

2. User confirms on /pay-confirm/ Generates order ID, logs in DB, encrypts payload, auto-submits to CCAvenue.

3. CCAvenue redirects back Response hits /pay-response/, gets decrypted, DB updated, result displayed.

⚙️ Session Handling (Hostinger-Safe)

Problem (originally): PHP-FPM mode couldn’t write to /opt/alt/php83/.../session, causing lost sessions. Fix (permanent): Plugin now defines its own session directory.

Add this snippet to ccavenue-payflow.php (already included in current version):

if (session_status() === PHP_SESSION_NONE) {
    $session_dir = WP_CONTENT_DIR . '/uploads/php_sessions';
    if (!is_dir($session_dir)) mkdir($session_dir, 0755, true);
    ini_set('session.save_path', $session_dir);
    session_start();
}

✅ Ensures consistent sessions even if LiteSpeed Cache is disabled.

🔐 Security & Stability

• All AJAX actions protected via check_ajax_referer()
• Admin access limited to users with manage_options
• Encrypted request/response handling via AES-128-CBC
• Escaped and sanitized output in all admin and frontend templates
• Database writes via $wpdb->prepare()
