[eluser]variouspixels[/eluser]
Here is some of my code, seems similar to yours.

view:

Code:

<strong class="field">
    <div>
        <label for="interest">Interest <em>(Check all that apply)</em></label>
    </div>
    &lt;input class="cb" type="checkbox" name="interests[]" value="General" &lt;?php echo set_checkbox('interests[]', 'general'); ?&gt; /&gt;General
    &lt;input class="cb" type="checkbox" name="interests[]" value="Promotion" &lt;?php echo set_checkbox('interests[]', 'promotion'); ?&gt;  /&gt;Promotion
    &lt;input class="cb" type="checkbox" name="interests[]" value="Other" &lt;?php echo set_checkbox('interests[]', 'other'); ?&gt;  /&gt;Other
    &lt;input class="cb" type="checkbox" name="interests[]" value="Stuff" &lt;?php echo set_checkbox('interests[]', 'stuff'); ?&gt;  /&gt;Stuff
</strong>
&lt;?php echo form_error('interest[]'); ?&gt;

controller:

Code:

$this->form_validation->set_rules('interests[]', 'Checkboxes', 'required'); // Interest Checkbox Required working
