问题描述
我正在向 Zend_Form 实例添加一个 select 元素，如下所示:
I am adding a select element to a Zend_Form instance as follows:
$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.
I have been searching the docs but cannot find a simple way of pre-setting an option of the select element to 'selected'.
推荐答案
我刚刚想出了如何去做.
I've just worked out how to do it.
必须使用元素的 setValue() 方法:
You have to use the setValue() method of the element:
$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.
