If products still don't show, next s --- +### v1.1.14 - Debug Logging Release (2025-12-31) + +#### Session 14: Adding Diagnostic Logging for Troubleshooting + +**Debug release** adding comprehensive logging to diagnose persistent product retrieval issues. + +**User feedback:** + +After v1.1.13 release, user reported: "so, the last known bugs are still there, lets go fixing them" + +This indicates that despite removing the `is_in_stock()` checks in v1.1.13, products STILL aren't showing in the selector. After three consecutive fix attempts (v1.1.11, v1.1.12, v1.1.13) all failed to resolve the issue, the strategy changed from attempting blind fixes to adding comprehensive diagnostic logging. + +**Strategic decision:** + +Instead of guessing at another fix, added debug logging throughout the product retrieval process to identify the actual problem. + +**Implementation:** + +Added `error_log()` statements throughout `includes/Product_Type.php` in the `get_available_products()` method, all wrapped in `WP_DEBUG` checks for production safety: + +```php +// Log selection criteria +if (defined('WP_DEBUG') && WP_DEBUG) { + error_log('Composable Product Criteria: ' . print_r($criteria, true)); +} + +// Log WP_Query arguments +if (defined('WP_DEBUG') && WP_DEBUG) { + error_log('Composable Product Query Args: ' . print_r($args, true)); +} + +// Log posts found by query +if (defined('WP_DEBUG') && WP_DEBUG) { + error_log('Composable Product Query Found: ' . $query->found_posts .

' - ' . $product->get_name()); +} + +// Log total available products +if (defined('WP_DEBUG') && WP_DEBUG) { + error_log('Total products available: ' . count($products)); +} +``` + +**What the logging reveals:** + +1. **Selection criteria**: Shows categories, tags, or SKUs being used +2. **WP_Query args**: Full query arguments before execution +3. **Posts found**: Number of posts the query retrieved +4. **Variable products**: How many variations each variable product has +5. **Product additions**: Each product/variation being added to the available list +6. **Final count**: Total products available at the end + +**Files modified:** + +- includes/Product_Type.php: Lines 126-217 (added 7 debug logging blocks) +- wc-composable-product.php: Version bump to 1.1.14 (lines 7, 23) +- CHANGELOG.md: v1.1.14 release notes + +**Release details:** + +- Package size: 417 KB (426,709 bytes) +- Git tag: v1.1.14 (annotated) +- Commits: efedd1b (debug logging), c036a37 (version bump), 33d2836 (release package) +- SHA-256: 7c943fc5a85d5a48125aaf9f2e42434b370c4fa168ca33cd1e3485deb55302a5 +- MD5: 7b8bbd9c1e0a5db59f89ae677f095430 + +**What this release does:** + +- No functional changes from v1.1.13 ✓ +- Zero performance impact in production (all logging behind WP_DEBUG check) ✓ +- Comprehensive diagnostic output when WP_DEBUG is enabled ✓ +- Will reveal exactly where products are being filtered out ✓ + +**How to use this debug release:** + +1. Install v1.1.14 plugin from releases/wc-composable-product-v1.1.14.zip +2. Enable WP_DEBUG in wp-config.php: + ```php + define('WP_DEBUG', true); + define('WP_DEBUG_LOG', true); + define('WP_DEBUG_DISPLAY', false); + @ini_set('display_errors', 0); + ``` +3. Visit a composable product page on the frontend +4. Check wp-content/debug.log for output +5.

Analyze log output to identify exact failure point +2. Determine root cause from diagnostic data +3. Implement targeted fix in v1.1.15 +4.
