正确使用CI中的form_dropdown（）

Question

I'm trying to figure out why the disabled attribute is not getting applied to my dropdown. As far as I know I'm applied the correct attributes to the form_dropdown function.

<?php if (in_array('No Wrestlers In Database', $allies)) {
$attributes = array('disabled' => 'disabled');
    echo form_dropdown( 'ally1', $allies, $attributes);
}
else {
    echo form_dropdown( 'ally1', $allies, $alliesList->ally1ID);
} ?>

Rendered HTML:

<select name="ally1">
    <option value="0">No Wrestlers In Database</option>
</select>                           

Answer 1

According to the documentation the third parameter is a string for the default selected item and the fourth is a string of attributes, not an array.

echo form_dropdown('ally1', $allies, 'default', 'disabled="disabled"');
