Magento网站的复选框被禁用不工做了

我想在Magento禁用复选框。但它不工做。

 $fieldset->addField(
            'checkstatus', 'checkboxes', array('Select Status')
            'label' => $this->__(',
            'name' => 'checkstatus[]',
            'values' => $options,
            'checked' => $optionselected,
            'disabled'=> true,
            'readonly'=>true
            )
        );

 

disabled 这会为单个复选框工做

$fieldset->addField(
            'checkstatus', 'checkboxes', array(
            'label' => $this->__('Select Status'),
            'name' => 'checkstatus[]',
            'values' => $options,
            'checked' => $optionselected,
            'disabled'=> true,
            'readonly'=>true
            )
        );
