Zend窗体-设置多个复选框的默认值

Question

我的复选框列表的HTML如下所示：

<dt id="list-label">
    <label for="list" class="optional">
        Choose which feeds to include in the mix
    </label>
</dt>

<dd id="list-element">
    <label for="list-1">
        <input type="checkbox" name="list[]" id="list-1" value="1">Marko Polo
    </label>

    <br />

    <label for="list-2">
        <input type="checkbox" name="list[]" id="list-2" value="2">Jeano Polo
    </label>
</dd>

我正在尝试用selected=selected预填充数据库中值为1的人。我认为以下几点是可行的：

$form->setDefaults(array('list-1'=>1,'list-2'=>1));

但事实并非如此。有什么办法吗？

Here is my form class code:

            $model = new Admin_Model_Db();
            $model->setTableName('graduates');
            $gradA = $model->getAllGraduates();

            foreach ($gradA as $grad){
                if (!empty($grad['twitter'])){
                    $twitter[$grad['id']] = $grad['firstname'] . ' ' . $grad['lastname'];
                }
            }

            $list = $this->CreateElement('multicheckbox', 'list')
                                  ->setLabel('Choose which feeds to include in the mix')
                                  ->setRequired(false)
                                  ->setMultiOptions($twitter);

Answer 1

您的表单元素名为list[]，这意味着当您的框被选中并以这种方式获得它们的值时：

 $list = $form->getElement('list')->getValue();

$list的值为数组(1，2)

因此，从逻辑上讲，这应该是可行的：

$form->setDefaults(array('list'=>array(1,2));
//if not, try with strings instead of integers array('1','2') 

Answer 2

试试这个：

$all_record = array('k1'=>'v1', 'k2'=>'v2');
$checked_values = aray('k1');

$checkbox = new Zend_Form_Element_MultiCheckbox('id', 
     array('multiOptions' => $all_records)
);

$checkbox->setValue($checked_values);

// ...

$this->addElement($checkbox);

当然，$this是Zend_Form :)
