zend框架-在表单文件元素和文件传输适配器上调用receive后找不到文件

Question

正如标题所说，我尝试调用Form Element和Adapter Object中的receive（）函数（当然不是一个接一个）。我打印了返回的值——在两种情况下都是1——这意味着receive（）返回true。但是在服务器上找不到该文件。我尝试将zend表单的加密类型设置为multipart/form数据，但没有帮助。我完全不知道，所以欢迎任何信息。在传输适配器上调用receive（）：文件位置和上载名称是常量。

$this->uploadName = $uploadName;
$this->upload = new Zend_File_Transfer_Adapter_Http();
$this->upload->setDestination($this->fileLocation);
...
$val = $this->upload->receive();
$quoteName = $this->upload->getFileName($this->uploadName);
$size = $this->upload->getFileSize($this->uploadName);
calling receive on form element:
//form creation - my form extends zend form
$staticForm = Srm_Form::getForm(my form,null,null,
my config);
$staticForm->setEnctype('multipart/form-data');
$staticForm->getElement(my file element name)->setDestination(my dest);
//calling receive
$form = Srm_Form::getForm(my form,null,null,my config);
$form->setEnctype('multipart/form-data');
if(!$form->isValid($_POST)){
print_r($form->getMessages());
}
//  echo $form->getElement(my file element)->getValue();
$val = $form->getElement(my file element)->receive();
echo "bbbbbb".$val;

我应该补充的是，当手动将file元素添加到表单后调用时，而不是通过使用配置文件来调用该代码。

好的，问题已经找到了-在处理提交的表单时，没有为文件元素设置目标（它是为其他地方的传输适配器手动设置的）。

我用Zend_form_Element_File元素定义了一个简单的表单

<?php
class Form_UploadForm extends Zend_Form
{
    public function __construct($options = null) 
    {
        parent::__construct($options);
        $this->setMethod('post');
        $this->setAttrib('enctype', 'multipart/form-data');
        $decors = array(
            array('ViewHelper'),
            array('HtmlTag'),//array('tag'=>'table')),
            array('Label', array('separator' => ' ')),                       // those unpredictable newlines
            array('Errors', array('separator' => ' ')),                      // in the render output
        );
        $file = new Zend_Form_Element_File('file');
        $file->setDestination('/a/b/c/upload');
        $file->setLabel('Document File Path')
              ->setRequired(true)
              ->addValidator('NotEmpty');
         $this->addElement($file);
        $submit = new Zend_Form_Element_Submit('submit');
        $submit->setLabel('Upload File');
        $this->addElement($submit);
    }
}
?>

我在控制器中的操作方法是

function uploadAction()
{
    $this->view->pageTitle = "Zend_Form File Upload Example";
    $this->view->bodyCopy = "<p>Please fill out this form.</p>";
    $form = new Form_UploadForm();
    if ($this->_request->isPost()) 
    {
        $formData = $this->_request->getPost();
        if ($form->isValid($formData)) 
        {
            try 
            {
                $form->file->receive(); 
            } 
            catch (Zend_File_Transfer_Exception $e) 
            {
                throw new Exception('unable to recieve : '.$e->getMessage());
            }
            $uploadedData = $form->getValues();
            //Zend_Debug::dump($form->file->getFileName(), 'tmp_file');
            $this->processFile($form->file->getFileName());
        }
        else 
        {
            $form->populate($formData);
        }
    }
    $this->view->form = $form;
}

注意-我不直接调用Zend_File_Transfer_Adapter_Http

最后一块是视图

<?php echo $this->form; ?>
