调用表单文件元素和文件传输适配器上的接收后找不到文件

问题描述

| 如标题所示，我尝试调用Form Element和Adapter Object的receive（）函数（当然不是一个接一个）。我打印了返回的值-在两种情况下均为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。 我完全一无所知，因此欢迎您提供任何信息。 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,my config);
$staticForm->setEnctype(\'multipart/form-data\');
$staticForm->getElement(my file element name)->setDestination(my dest);

//calling receive
$form = Srm_Form::getForm(my form,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;

我应该补充一点，当将文件元素手动添加到表单后而不是通过使用配置文件调用该代码时，该代码可以工作。 好的，发现问题了- 在处理提交的表单时，未为文件元素设置目的地（在其他地方为传输适配器手动设置了目的地）。     

解决方法

        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\',// 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; ?>
