问题描述

我正在将yii下拉列表与活动记录一起使用，因为我正在使用multiselect下拉列表.我正在创建从下拉菜单中选择多个选项的数据.在更新时，我想禁用在创建时选择的所选选项.

I am using yii dropdown with active records in that i am using multiselect dropdown. i am creating data with in which i am selected multiple option from dropdown.. while updating i want to disable selected option which i selected at time of creation.

<code>
<?php 
$savedSections  =   helpers::getQuestionnaireSectionList($model->questionnaire_id);

$data   =   helpers::getSection();

$listData       =   CHtml::listData($data, 'section_id', 'section_name');

$htmlOptions = array('size' => '5', 'multiple' => 'true','style'=>'width: 333px');

$queSection->section_ref_id =   $savedSections; #sec2

echo $form->listBox($queSection,'section_ref_id',$listData, $htmlOptions); #sec1

?>

推荐答案

将您的$htmlOptions更改为:

$htmlOptions = array(
    'size' => '5',
    'multiple' => 'true',
    'options'=>array(45=>array('disabled'=>'disabled')),
);

45这是section_id

，如果您想了解它是如何实现的，可以看一下 https://github.com/yiisoft/yii /blob/master/framework/web/helpers/CHtml.php#L2516
