je-listings-callback

What problem does it solve?

This Skill helps you register a JetEngine Listings callback that transforms Dynamic Field meta values in a listing context, without running into the common “callback applied but value is empty” failure caused by PHP callable validation.

Core Features & Use Cases

• Register custom Dynamic Field transforms: Add your own “Format … / Convert … / Pretty …” callback into JetEngine’s Dynamic Field output pipeline.
• Choose legacy or modern registration: Use either the three-filter legacy approach or the modern $manager->register_callback() flow.
• Avoid silent empty-field bugs: Ensure the callback identifier satisfies JetEngine’s is_callable() gate by using a real global function name or a fully-qualified static method string.
• Control the UI/args correctly: Provide callback-specific argument controls (and condition in legacy mode) so settings appear only when your callback is selected.

Quick Start

Use the jet-engine/callbacks/register action and register your callback as a fully-qualified PHP-callable string, then verify the Dynamic Field “Callback to filter field value” dropdown contains your new option and the rendered value is no longer blank.
