Fix: WordPress Customizer Request Bukan AJAX WooCommerce

🔴 Root Cause

Request dengan customize_changeset_uuid parameter:

checkout-2/?customize_changeset_uuid=...

Ini BUKAN endpoint AJAX WooCommerce!

Ini adalah WordPress Customizer request, bukan AJAX request. Customizer menggunakan parameter customize_changeset_uuid untuk preview changes, tapi ini bukan AJAX request.

Masalah

Code kita sebelumnya menganggap semua request dengan parameter tertentu adalah AJAX, sehingga:

1. Output buffer cleaning di-trigger untuk Customizer requests
2. Error suppression di-trigger untuk Customizer requests
3. BlockUI logic mungkin di-trigger untuk Customizer requests
4. Customizer tidak bisa bekerja dengan benar

Fix yang Diterapkan

1. Exclude Customizer dari Helper Function

Lokasi: inc/woocommerce.php - augoose_is_wc_ajax_request()

Perubahan:

• ✅ Check customize_changeset_uuid parameter di awal
• ✅ Check is_customize_preview() function
• ✅ Return false jika ini Customizer request

Code:

function augoose_is_wc_ajax_request() {
    // CRITICAL: Exclude WordPress Customizer requests
    if ( isset( $_REQUEST['customize_changeset_uuid'] ) || 
         isset( $_GET['customize_changeset_uuid'] ) || 
         isset( $_POST['customize_changeset_uuid'] ) ||
         is_customize_preview() ) {
        return false; // This is Customizer, not WooCommerce AJAX
    }
    // ... rest of function
}

2. Exclude Customizer dari Output Buffer Cleaning

Lokasi: inc/woocommerce.php - wp_augoose_clean_output_for_woocommerce_ajax()

Perubahan:

• ✅ Early return jika detect Customizer request
• ✅ Don't interfere dengan Customizer output

Code:

function wp_augoose_clean_output_for_woocommerce_ajax() {
    // CRITICAL: Exclude WordPress Customizer requests
    if ( isset( $_REQUEST['customize_changeset_uuid'] ) || 
         is_customize_preview() ) {
        return; // Don't interfere with Customizer
    }
    // ... rest of function
}

3. Exclude Customizer dari Error Suppression

Lokasi: inc/woocommerce.php - wp_augoose_suppress_harmless_warnings()

Perubahan:

• ✅ Early return jika detect Customizer request
• ✅ Customizer needs to see warnings/notices for debugging

Code:

function wp_augoose_suppress_harmless_warnings() {
    // CRITICAL: Exclude WordPress Customizer requests
    if ( isset( $_REQUEST['customize_changeset_uuid'] ) || 
         is_customize_preview() ) {
        return; // Don't suppress warnings in Customizer
    }
    // ... rest of function
}

4. Exclude Customizer dari Template Redirect

Lokasi: inc/woocommerce.php - wp_augoose_ensure_classic_checkout()

Perubahan:

• ✅ Early return jika detect Customizer request
• ✅ Customizer needs to work normally

Code:

function wp_augoose_ensure_classic_checkout() {
    // CRITICAL: Skip for WordPress Customizer requests
    if ( isset( $_REQUEST['customize_changeset_uuid'] ) || 
         is_customize_preview() ) {
        return; // Don't interfere with Customizer
    }
    // ... rest of function
}

Detection Logic

Customizer Detection:

1. Check $_REQUEST['customize_changeset_uuid'] parameter
2. Check $_GET['customize_changeset_uuid'] parameter
3. Check $_POST['customize_changeset_uuid'] parameter
4. Check is_customize_preview() WordPress function

Jika salah satu true → Ini Customizer, bukan AJAX → Skip semua AJAX-specific logic

Test Verification

Test 1: Customizer Request

# Simulate Customizer request
curl "https://augoose.co/checkout-2/?customize_changeset_uuid=test123" \
  -v 2>&1 | head -30

Expected:

• Response is normal HTML (not JSON)
• No output buffer cleaning interference
• No error suppression
• Customizer works normally

Test 2: WooCommerce AJAX Request

# Simulate WooCommerce AJAX request
curl -X POST "https://augoose.co/?wc-ajax=update_order_review" \
  -H "Content-Type: application/x-www-form-urlencoded" \
  -d "billing_first_name=Test" \
  -v 2>&1 | head -30

Expected:

• Response is JSON (not HTML)
• Output buffer cleaning works
• Error suppression works
• AJAX works normally

Summary

Fix ini critical:

• ✅ Exclude Customizer dari semua AJAX-specific logic
• ✅ Customizer bisa bekerja normal
• ✅ WooCommerce AJAX tetap berfungsi
• ✅ No false positives

Result: Customizer dan WooCommerce AJAX sekarang tidak saling interfere.
