wp_mark_auto_generate_control_attributes() │ WP 7.0.0

Marks user-defined attributes for auto-generated inspector controls.

This filter runs during block type registration, before the WP_Block_Type is instantiated. Block supports add their attributes AFTER the block type is created (via WP_Block_Supports::register_attributes()), so any attributes present at this stage are user-defined.

The marker tells generateFieldsFromAttributes() which attributes should get auto-generated inspector controls. Attributes are excluded if they:

• Have a 'source' (HTML-derived, edited inline not via inspector)
• Have role 'local' (internal state, not user-configurable)
• Have an unsupported type (only 'string', 'number', 'integer', 'boolean' are supported)
• Were added by block supports (added after this filter runs)

No Hooks.

Returns

Array. mixed> Modified block type arguments.

Usage

wp_mark_auto_generate_control_attributes( $args ): array;
