cafe_delete_field()

Purpose

Deletes the saved value of a field for one object.

cafe_delete_field( string $selector, mixed $object_id = null, ?string $object_type = null ): bool

Parameter	Type	Default	Description
`$selector`	string	-	Field name or field key.
`$object_id`	mixed	`null`	Which object. `null` means the current object.
`$object_type`	string\|null	`null`	Object type, or `null` to infer it.

true when the value is gone (also when nothing was saved), false when the field or object cannot be found or the database fails.

cafe_delete_field(
	'hero_title',
	$post_id
);

Deletes the value only; the field definition stays.
Fires cafe_before_delete_field and cafe_after_delete_field.
When WordPress deletes a post, term, user or comment, CAFE removes its values automatically: you do not need to call this.
