php - Zend Framework - 在选择框下拉列表中设置 'selected' 值

Question

我正在向 Zend_Form 实例添加一个选择元素，如下所示:

  $user = $form->createElement('select','user')->setLabel('User: ')->setRequired(true);
  foreach($users as $u)
        {
            if($selected == $u->id)
            {
                $user->addMultiOption($u->id,$u->firstname.' '.$u->lastname);
                //*** some way of setting a selected option? selected="selected"

            }
            else
                $user->addMultiOption($u->id,$u->firstname.' '.$u->lastname);
        }

我一直在搜索文档，但找不到将选择元素的选项预先设置为“已选择”的简单方法。

Answer 1

我刚刚弄清楚如何去做。

您必须使用元素的 setValue() 方法:

$user = $form->createElement('select','user')->setLabel('User: ')->setRequired(true);
    foreach($users as $u)
        $user->addMultiOption($u->id,$u->firstname.' '.$u->lastname);

$user->setValue($selected); //$selected is the 'value' of the <option> that you want to apply selected="selected" to.
