set_value, set_select for form_multiselect in v2

[eluser]zac[/eluser]
According to the user guide, set_select() is intended to be used when you're generating the select HTML by hand, like this:

Code:

<select name="myselect">
<option value="one" &lt;?php echo set_select('myselect', 'one', TRUE); ?&gt; >One</option>
<option value="two" &lt;?php echo set_select('myselect', 'two'); ?&gt; >Two</option>
<option value="three" &lt;?php echo set_select('myselect', 'three'); ?&gt; >Three</option>
</select>

Instead, form_multiselect() wants an array of values as its third parameter. The $_POST array will contain whatever values the user selected:

Code:

<?=form_multiselect('goal_id[]', $goals, $_POST['goal_id[]'])?>

Or if you're using CI's Input class, then something like this:

Code:

<?=form_multiselect('goal_id[]', $goals, $this->input->post('goal_id[]'))?>
