🔴 THE REAL PROBLEM: Gateway Instance Cache
Problem Analysis:
1. ✅ API call works
2. ✅ Database saves correctly
3. ✅ Cache clears properly
4. ❌ Gateway instance still has OLD settings in memory!
Root Cause:
WC()->payment_gateways()->payment_gateways() returns gateway INSTANCES
These instances load settings ONCE on construction
Even after DB save + cache clear, instances still have old $gateway->enabled value!
The Culprit (Line 83):
'enabled' => $gateway->enabled === 'yes' // ❌ Reading from stale instance!
The Fix:
Before transforming gateway, force reload from DB:
$gateway->init_settings(); // ✅ Reloads from database!
This makes $gateway->enabled read fresh value from wp_options.
Changes:
1. get_gateway(): Added $gateway->init_settings()
2. get_gateways(): Added $gateway->init_settings() in loop
3. PaymentsController: Better boolean handling with filter_var()
Why This Wasn't Obvious:
- Cache clearing worked (wp_cache_flush ✅)
- WC reload worked (WC()->payment_gateways()->init() ✅)
- But gateway INSTANCES weren't reloading their settings!
WooCommerce Gateway Lifecycle:
1. Gateway constructed → Loads settings from DB
2. Settings cached in $gateway->settings property
3. We save new value to DB ✅
4. We clear cache ✅
5. We reload WC gateway manager ✅
6. BUT: Existing instances still have old $gateway->settings ❌
7. FIX: Call $gateway->init_settings() to reload ✅
Result: ✅ Toggle now works perfectly!
Files Modified:
- PaymentGatewaysProvider.php: Force init_settings() before transform
- PaymentsController.php: Better boolean validation
This was a subtle WooCommerce internals issue - gateway instances
cache their settings and don't auto-reload even after DB changes!
