CakePHP根据特定条件将输入表单设置为禁用

Hello I've made a form in my ctp file like this:

<?php echo $this->Form->input('Status', array(
'div' => array('class' => 'xDiv'),
'label' => __('Status'),
'type' => 'select',
'empty' => 'Complete',//dummy
'class' => __('Status'),
'options' => $options
)); ?>

When a certain condition is satisfied I want my form to be disabled adding feature 'disabled' => true. How can I do this without changing cakePHP functionality, meaning not going back to plain html and echo the feature.

I'd do something like this:

<?php echo $this->Form->input('Status', array(
                                'div' => array('class' => 'xDiv'),
                                'label' => __('Status'),
                                'type' => 'select',
                                'empty' => 'Complete',//dummy
                                'class' => __('Status'),
                                'options' => $options
                                'disabled' => ($foo == $bar ? true : false)
)); ?>

Replacing $foo == $bar with whatever logic you need. Making it as verbose or condensed as you like. See: ternary operators.
