如何在yii的更新视图中的多选列表框中加载选定的列表项?

问题描述

我在Create-Service-Form中的Staff中有一个multiple select-list-box，用于在创建新服务时选择多个人员.为此，我可以在一项服务上分配多名员工.

I have a multiple select-list-box for Staff in Create-Service-Form, used to select multiple staff when creating a new service. for this i can assign multiple staff on a single service.

我将staff_id字段另存为:
$model->staff_id = serialize($model->staff_id);

这是用于多选列表框的更新视图代码:

<div class="row">
    <?php echo $form->labelEx($model,'staff_id'); ?>
    <?php
          $data = array('1' => 'Sam', '2' => 'john', '3' => 'addy');
          $htmlOptions = array('size' => '5', 'prompt'=>'Use CTRL to Select Multiple Staff', 'multiple' => 'multiple');
          echo $form->ListBox($model,'staff_id', $data, $htmlOptions);
    ?>
    <?php echo $form->error($model,'staff_id'); ?>
</div>

问题是，当我加载用于更新服务的表格时.我该如何选择以前保存在数据库中的人员?

Problem is, when i load form for updating a service. how do i select those staff, which are previously saved in database?

我尝试了此 dropDownList属性，但没有工作.
$ select |字符串|选定的值

I tried this dropDownList-attributes, but it not working.
$select | string | the selected value

如果有人有解决方案，那么建议我.谢谢所有伴侣...

if someone has solution, then suggest me. Thanks All Mates...

      '102' => array('selected' => 'selected'),
      '103' => array('selected' => 'selected'),
    );
    $htmlOptions = array('size' => '5', 'prompt'=>'Use CTRL to Select Multiple Staff', 'multiple' => 'true', 'options' => $selected);
    echo $form->listBox($model,'staff_id', $data, $htmlOptions);
