Form Validation with Array

[eluser]Unknown[/eluser]
I'm trying to use Form Validation Class using array text-field.

By the way, user manual says:

* Using Arrays as Field Names

Or to re-populate the field you would use:

Code:

<input type="text" name="options[]" value="<?php echo set_value('options[]'); ?>" size="50" />

(http://ellislab.com/codeigniter/user-gui...ysasfields)

But "set_value" returns array when it was given array as field name.
So i think that the sample doesn't work correctly.

It will output:

Code:

<input type="text" name="options[]" value="Array"...

Is this a manual's mistake?
