MWA Charity
Developed a custom WordPress theme using Elementor Pro, custom post types, and Advanced Custom Fields (ACF), solving donor drop-off through custom Gravity Forms with integrated Stripe payments and automated PDF invoice generation.
The Challenge
Replacing a fragmented third-party donation plugin system that caused high checkout failure rates and lacked support for custom tax-deductible PDF receipt generation.
The Solution
Built a unified custom WordPress theme on Elementor Pro with tailored Custom Post Types and Advanced Custom Fields. Integrated Gravity Forms with Stripe payments to stream checkout, and developed custom PHP handlers to compile and email PDF invoices automatically on successful transactions.
My Approach
Custom Post Types & Fields
Designed custom post structures using Advanced Custom Fields (ACF) to allow admins to publish campaigns with distinct financial goals.
Gravity Forms Stripe Integration
Constructed secure, responsive single-page donation checkout flows utilizing Gravity Forms mapped to Stripe payment intents.
Automated PDF Receipting
Programmed server-side PHP hooks that capture transaction metadata and generate clean tax-compliant PDF invoices on checkout success.
Results & Impact
Robust processing via Gravity Forms and Stripe
Eliminated manual invoice compiling and emailing
Technical Highlights
Gravity Forms Stripe Payment Callback Hook
Capturing transaction metadata to generate and mail PDF invoices dynamically.
add_action('gform_stripe_charge_captured', function($entry, $charge, $action) { $invoice_pdf = generate_donation_pdf($entry); send_donation_invoice($entry['email'], $invoice_pdf); }, 10, 3);Lessons Learned
- Decoupling PDF generation to run asynchronously prevents checkout connection timeouts.
- Custom post hierarchies with ACF keep content management intuitive for non-technical administrators.
Next Steps
- Deploy automated SMS payment notifications for donors.
- Configure multi-currency Stripe elements gateways for international contributors.
