Question

正如标题所说，我尝试调用表单元素和适配器对象的receive（）函数（当然不是一个接一个）。我打印了返回的值 - 两种情况都是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-data - 没有帮助。我完全无能为力，欢迎任何信息。在传输适配器上调用receive（）：文件位置和上传名称是常量。

$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;

我应该补充说明此代码在文件元素手动添加到表单后调用而不是使用配置文件时有效。

好的，发现了问题 - 处理提交的表单时，没有为文件元素设置目标（在其他地方为传输适配器手动设置）。

我使用Zend_Form_Element_File元素

定义一个简单的表单

<?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Controller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; ?>

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
