pre_attachment_url_to_postid

Filters the attachment ID to allow short-circuit the function. Allows plugins to short-circuit attachment ID lookups. Plugins making use of this function should return: - 0 (integer) to indicate the attachment is not found, - attachment ID (integer) to indicate the attachment ID found, - null to indicate WordPress should proceed with the lookup. Warning: The post ID may be null or zero, both of which cast to a boolean false. For information about casting to booleans see the {@link https://www.php.net/manual/en/language.types.boolean.php PHP documentation}. Use the === operator for testing the post ID when developing filters using this hook.
