Fixes Implemented

✅ Critical Issue #1: handle_renewal_success Now Sets Status to Active

File: [SubscriptionManager.php](file:///Users/dwindown/Local Sites/woonoow/app/public/wp-content/plugins/woonoow/includes/Modules/Subscription/SubscriptionManager.php#L708-L719)

Change:

$wpdb->update(
    self::$table_subscriptions,
    [
+       'status' => 'active',
        'next_payment_date' => $next_payment,
        'last_payment_date' => current_time('mysql'),
        'failed_payment_count' => 0,
    ],
    ['id' => $subscription_id],
-   ['%s', '%s', '%d'],
+   ['%s', '%s', '%s', '%d'],
    ['%d']
);

---

✅ Critical Issue #2: Added Renewal Reminder Handler

File: [SubscriptionModule.php](file:///Users/dwindown/Local Sites/woonoow/app/public/wp-content/plugins/woonoow/includes/Modules/Subscription/SubscriptionModule.php)

Changes:

1. Added action hook registration:

add_action('woonoow/subscription/renewal_reminder', [__CLASS__, 'on_renewal_reminder'], 10, 1);

2. Added event registration:

$events['subscription_renewal_reminder'] = [
    'id' => 'subscription_renewal_reminder',
    'label' => __('Subscription Renewal Reminder', 'woonoow'),
    // ...
];

3. Added handler method:

public static function on_renewal_reminder($subscription)
{
    if (!$subscription || !isset($subscription->id)) {
        return;
    }
    self::send_subscription_notification('subscription_renewal_reminder', $subscription->id);
}

---

✅ Warning Issue #3: Added Duplicate Renewal Order Prevention

File: [SubscriptionManager.php::renew](file:///Users/dwindown/Local Sites/woonoow/app/public/wp-content/plugins/woonoow/includes/Modules/Subscription/SubscriptionManager.php#L511-L535)

Change: Before creating a new renewal order, the system now checks for existing pending orders:

$existing_pending = $wpdb->get_row($wpdb->prepare(
    "SELECT so.order_id FROM ... WHERE ... AND p.post_status IN ('wc-pending', 'pending', 'wc-on-hold', 'on-hold')",
    $subscription_id
));

if ($existing_pending) {
    return ['success' => true, 'order_id' => (int) $existing_pending->order_id, 'status' => 'existing'];
}

Also allowed on-hold subscriptions to renew (in addition to active).

---

✅ Warning Issue #4: Removed Duplicate Route Registration

File: [CheckoutController.php](file:///Users/dwindown/Local Sites/woonoow/app/public/wp-content/plugins/woonoow/includes/Api/CheckoutController.php)

Change: Removed duplicate /checkout/pay-order/{id} route registration (was registered twice).

---

✅ Warning Issue #5: Added has_settings to Subscription Module

File: [ModuleRegistry.php](file:///Users/dwindown/Local Sites/woonoow/app/public/wp-content/plugins/woonoow/includes/Core/ModuleRegistry.php#L64-L78)

Change:

'subscription' => [
    // ...
    'default_enabled' => false,
+   'has_settings' => true,
    'features' => [...],
],

Now subscription settings will appear in Admin SPA > Settings > Modules > Subscription.

---

✅ Issue #10: Replaced Transient Tracking with Database Column

Files:

• [SubscriptionManager.php](file:///Users/dwindown/Local Sites/woonoow/app/public/wp-content/plugins/woonoow/includes/Modules/Subscription/SubscriptionManager.php) - Added reminder_sent_at column
• [SubscriptionScheduler.php](file:///Users/dwindown/Local Sites/woonoow/app/public/wp-content/plugins/woonoow/includes/Modules/Subscription/SubscriptionScheduler.php) - Updated to use database column

Changes:

1. Added column to table schema:

reminder_sent_at DATETIME DEFAULT NULL,

2. Updated scheduler logic:

// Query now includes:
AND (reminder_sent_at IS NULL OR reminder_sent_at < last_payment_date OR ...)

// After sending:
$wpdb->update($table, ['reminder_sent_at' => current_time('mysql')], ...);

9	"Renew Early" only for active subscriptions	Confirmed as acceptable UX
11	API permissions correctly configured	Verified ✓

Database Migration Note

Important

The reminder_sent_at column has been added to the subscriptions table schema. Since dbDelta() is used, it should be added automatically on next module re-enable or table check. However, for existing installations, you may need to:

1. Disable and re-enable the Subscription module in Admin SPA, OR
2. Run: ALTER TABLE wp_woonoow_subscriptions ADD COLUMN reminder_sent_at DATETIME DEFAULT NULL;
