Checkout Pilot for WooCommerce

Version: 1.0.4
Author: WP Plugin Pilot
Requires: WordPress 6.0+ , WooCommerce 7.0+
PHP: 7.4 or higher

1. Overview

Checkout Pilot for WooCommerce is a proactive checkout monitoring tool designed to detect silent failures that break the WooCommerce checkout experience. Many checkout issues occur without visible frontend errors, including PHP fatal errors, session problems, gateway misconfiguration, or missing checkout forms.

This plugin simulates real checkout requests in the background and analyzes the server response. If any issue is detected, it logs the problem and optionally notifies the store administrator before customers encounter failed purchases.

What It Detects

  • Checkout page not loading
  • Missing WooCommerce checkout form
  • Empty cart session failures
  • Fatal PHP errors
  • Payment gateways not available
  • Server timeout issues
  • Unexpected HTML responses

2. Installation

Automatic Installation

  1. Go to Plugins → Add New
  2. Search for "Checkout Pilot for WooCommerce"
  3. Click Install
  4. Click Activate

Manual Installation

  1. Upload the checkout-pilot-for-woocommerce folder to:
  2. /wp-content/plugins/
  3. Activate the plugin from WordPress admin
  4. Ensure WooCommerce is active

After activation, the plugin automatically schedules monitoring checks and begins logging results.

3. How Monitoring Works

The plugin uses WordPress Cron to run scheduled health checks every 15 minutes. Each check:

  1. Requests the WooCommerce checkout URL
  2. Simulates cart/session conditions
  3. Analyzes HTML response
  4. Detects PHP errors
  5. Checks checkout form presence
  6. Validates payment gateways
  7. Logs results
  8. Sends alerts if needed

Cron Schedule

  • Hook: checpifo_check_event
  • Interval: 15 minutes
  • Method: WP-Cron
  • Runs silently in background

4. Monitoring Checks

Checkout Availability

The plugin verifies that the checkout form exists in the HTML response. Missing forms indicate:

  • Theme conflicts
  • Plugin conflicts
  • PHP errors
  • Template overrides

Session Health

Detects if WooCommerce session handling is broken. This happens when:

  • Cookies blocked
  • Object cache conflicts
  • Server misconfiguration
  • Cache plugins interfering

PHP Error Detection

The plugin scans response HTML for:

  • Fatal error
  • Uncaught exception
  • Stack traces
  • Warning output

Payment Gateway Validation

Ensures at least one payment method is available. If none exist, checkout becomes unusable.

5. Admin Dashboard

The plugin adds a dashboard page inside WordPress admin providing real-time monitoring data.

Dashboard Features

  • Cron Status — Shows last and next scheduled run
  • Run Check Now — Manual monitoring trigger
  • Status Cards — Warnings and errors overview
  • Event Log — Last 50 monitoring events
  • Error Messages — Detailed diagnostics

This allows store owners to instantly verify checkout health after updates.

6. Notifications & Alerts

When a critical issue is detected, the plugin sends an email notification to the site administrator.

Email Alert Conditions

  • Checkout form missing
  • PHP fatal error detected
  • No payment gateways
  • Checkout unavailable

Smart Alert Throttling

  • Limits alerts to once every 15 minutes
  • Prevents email flooding
  • Only alerts on real failures

7. Logs & Data Storage

The plugin stores monitoring data in WordPress options:

  • checpifo_logs — Last 100 monitoring events
  • checpifo_last_run — Timestamp of last check
  • checpifo_last_alert — Last alert sent

Logs automatically rotate to prevent database bloat.
