是否可以将模块的复选框设置为“只读”?

我正在编写一个安全模块,允许为多站点drupal设置启用某些模块。现在,我们可以使用下面的代码片段轻松地禁用模块。

我们希望将表单元素设置为只读,然后启用仅启用/禁用子集的功能。

function disable_form_fields_form_alter(&$form, $form_state, $form_id) {

    //get handle on drupal user var
    global $user;

    //if we are uid == 1 then we can edit this stuff...
    if($user->uid !=1 && variable_get('osu_update_lockdown',1)==1){

        if ($form_id == 'system_modules'){

            //find all the modules not disabled
            $modules_to_disabled = array_diff_key($form['status']['#options'],     array_flip($form['status']['#disabled_modules']));

            //for each not in our disabled list lets add it in
            foreach($modules_to_disabled as $name => $value){
                $form['status']['#disabled_modules'][] = $name;
            }

            //disable non-checked boxes
            foreach($form['status']['#options'] as $key=>$val){
                $form['status']['#process']['system_modules_disable'][0][]=$key;
            }
            //disable checked boxes
            foreach($form['status']['#default_value'] as $key=>$val){
                $form['status']['#process']['system_modules_disable'][0][]=$val;
            }

            unset($form['buttons']['submit']);

        }
    } 
}
