For developers: what the fix changed

The fix introduces an allowlist for order fields in `OrderCreateResource::validateInput()` to reject unexpected properties, and updates `validateEntity()` to enforce all field constraints. It also adds a settings form in `SettingsForm.php` to configure permitted custom order fields.

Get in touch

Tell me who you are, what your organisation does, and what you need. That might be a Drupal site that needs looking after, an upgrade to get done before December, or an agency that needs Drupal cover.

If I can help, I'll say so and suggest a call. If I can't, I'll tell you straight away rather than waste your time.

For context: I work mainly with UK charities, membership bodies and research organisations, and with the agencies that look after their websites. Not recruiters.

Or start smaller and connect with me on LinkedIn. That's where I post what I find digging around in charity and grants data, and where the free tools turn up first.
