By default DB queries return their results in the drivers native format, for performance reasons.
For example, in case of MySQL, MySQL_Result objects are returned. These objects are provided by the PHP driver, and are readonly.
In FuelPHP, for security reasons, everything you pass to a View will be encoded. This means you can't pass DB results directly to a View, since encoding means modifying, which you can't do with a read-only object as you have noticed.
Several solutions exist: - use ORM, it's objects don't have this issue - use as_array() to convert the result to an array - use as_object('stdClass') to convert the result into standard class objects (which are read-write) - Whitelist the result objects in your config.php (not recommended for security reasons)
