wp_validate_logged_in_cookie( int|bool $user_id )

Validates the logged-in cookie.

Description

Checks the logged-in cookie if the previous auth cookie could not be validated and parsed.

This is a callback for the ‘determine_current_user’ filter, rather than API.

Parameters

$user_id

(int|bool) (Required) The user ID (or false) as received from the determine_current_user filter.

Return

(int|false) User ID if validated, false otherwise. If a user ID from an earlier filter callback is received, that value is returned.

		return false;
	}
