zend-framework - Zend 表单文本值保持为空

Question

我创建了一个简单的上传表单，但在提交数据时遇到了一些问题。

该文件已正确上传，但我的小说明字段保持为空。

这是我的表格:

class Upload_Form_Uploadvideo extends Zend_Form{
public function init()
{
    $this->setName('video')
    ->setAction('interface/videoupload')
    ->setMethod('post');


    #id
    $id = new Zend_Form_Element_Hidden('id');
    $id->addFilter('Int');

    #Textfield "Videofile"
    $video = new Zend_Form_Element_File('videofile', array(
        'label'         => 'Videofile')
    );
    $video->setDestination(APPLICATION_PATH.'/upload/video/toConvert/');

    #Textfield "Videofile"
    $desc = new Zend_Form_Element_Text('videodescription', array(
        'label'         => 'Description')
    );
    $desc->setAttrib('value','The description is not optional!');
    $desc->setAttrib('size','25');


    #Submit
    $submit = new Zend_Form_Element_Submit('submit', array('label' => 'Upload Video'));
    $submit->setAttrib('id', 'submitbutton');


    #bringing everything together
    $this->addElements(array($id,$video,$desc,$submit));

    }
}

Controller ，将其提供给 View :

public function videouploadAction()
{
    #in production this code goes to the index()
    if(!$this->getRequest()->isPost()){
        return $this->_forward('index');
    }
    $form = $this->getForm();
    $this->view->via_getpost = var_dump($this->_request->getPost());

    $this->view->via_getvalues= var_dump($form->getValues());

}

现在，我 var_dump $this->_request->getPost() 和 $form->getValues()。

输出如下:

array[$this->_request->getPost()]

'id' => string '0' (length=1)
'MAX_FILE_SIZE' => string '134217728' (length=9)
'videodescription' => string 'This is a test-video' (length=20)
'submit' => string 'Upload Video' (length=12)


array [$form->getValues()]

'id' => int 0
'videofile' => string 'swipeall.avi' (length=12)
'videodescription' => null

另外，我设置了“value”-attrib，没有任何效果。当用户加载站点时，我打算在框中写一些东西。

我是 Zend 的新手，所以我想我只是在监督一些愚蠢的事情，尽管我找不到它。

更新:

我真的必须通过 $_POST-Data

$formdata = $this->getRequest()->getPost();

Answer 1

用

$desc->setValue('The description is not optional!');

代替

$desc->setAttrib('value','The description is not optional!');
