Why Are My Required Checkout Fields Not Validating?

If you're using the Checkout Field Editor (Checkout Manager) for WooCommerce and finding that your required fields aren't being properly validated at checkout, you're not alone. This is a common issue that can occur for several reasons, from plugin conflicts to WooCommerce's default behavior with certain field types.

Common Causes of Validation Issues

1. Country-Specific Field Requirements

WooCommerce has built-in logic that changes field requirements based on the selected country. For example, the postcode field might be required for some countries but optional for others. This can override your plugin settings.

2. Plugin Version Compatibility

Older versions of the plugin may have bugs that affect validation. The 'double star' issue for required fields was specifically addressed in version 2.1.3.

3. WooCommerce Blocks Compatibility

If you're using the new WooCommerce blocks on your checkout page, most checkout field plugins (including Checkout Field Editor) are not currently compatible with this system.

4. Free Version Limitations

The free version of Checkout Field Editor has limited validation options. Custom validation using regular expressions or specific validation rules (like character limits) are not supported in the free version.

5. Dynamic Field Population Issues

If you're dynamically populating select fields via AJAX, version changes might affect how these values are validated and recorded.

Solutions to Try

Solution 1: Force Field Requirements with Code

For address fields like postcode that change based on country, you can use this code snippet in your child theme's functions.php file to make them required for all countries:

add_filter('thwcfd_address_field_override_required','__return_true');

Solution 2: Check Your Plugin Version

Ensure you're using at least version 2.1.3 of Checkout Field Editor, as this version fixed the 'double star' display issue for required fields.

Solution 3: Use Traditional Checkout Shortcode

If you're using WooCommerce blocks, switch to the traditional checkout system by creating your checkout page with the shortcode: [woocommerce_checkout]

Solution 4: Verify Plugin Compatibility

If you're using multiple plugins that modify checkout fields (especially shipping calculators or gift card plugins), there may be conflicts that affect field validation. Test with other plugins disabled to identify conflicts.

Solution 5: Understand Free Version Limitations

Recognize that the free version only supports basic validation types (Email and Phone). For custom validation patterns or advanced requirements, you'll need to implement custom code solutions.

When to Seek Further Help

If none of these solutions resolve your validation issues, the problem might require more technical investigation. The Checkout Field Editor (Checkout Manager) for WooCommerce team maintains a support system for detailed troubleshooting of complex issues, especially those that might be related to specific server configurations or unique plugin combinations.

Remember to always test changes on a staging site first and keep regular backups of your site before implementing code solutions.
