zend zend_file_transfer_adapter_http重命名问题

zend-file zend-framework

Corey · 技术社区 · 16 年前

我有一个关于在Zend上传文件后重命名文件的问题。我不知道在哪里放置重命名过滤器。这就是我要的。我试过移动东西,但我迷路了。当前它确实将文件上载到“我的照片”文件夹,但不重命名该文件。谢谢你的帮助!

if($this->_request->isPost()) 
{
    $formData = $this->_request->getPost();

    if ($form->isValid($formData)) 
    {
        $adapter = new Zend_File_Transfer_Adapter_Http();
        $adapter->setDestination(WWW_ROOT . '/photos');

        $photo = $adapter->getFileInfo('Photo');

        $adapter->addFilter('Rename', array(
            $photo['Photo']['tmp_name'], 
            WWW_ROOT . '/photos/' . $this->memberId . '.jpg', 
            true
        )); 

        if ($adapter->receive()) 
        {
            echo 'renamed';
        }
    }
}

实际上,有一种更简单的方法可以做到这一点。您只需将false作为zend_file_transfer_adapter_http对象的getfilename方法的第二个参数传递。然后,您可以通过在文件中附加一个用户ID来重命名该文件,或者解析文件名来获取扩展名(如果您愿意的话)。

// upload a file called myimage.jpg from the formfield named "image".

$uploaded_file = new Zend_File_Transfer_Adapter_Http();
$uploaded_file->setDestination('/your/path/');
    try {
        // upload the file
        $uploaded_file->receive();
    } catch (Zend_File_Transfer_Exception $e) {
        $e->getMessage();
    }
$file_name = $uploaded_file->getFileName('image', false);
// this outputs "myimage.jpg"

$file_path = $uploaded_file->getFileName('image');
// this outputs "/your/path/myimage.jpg"

// now use the above information to rename the file

我通过设置一个过滤器来做到这一点。请注意,我没有设置目标路径。

$adapter= new Zend_File_Transfer_Adapter_Http();
$adapter->addFilter('Rename',array('target' => WWW_ROOT . '/photos/' . $this->memberId . '.jpg'));

$adapter->receive();

根据文档,您不应该将路径放在目标中

Zend框架有更好更安全的方法…

创建助手类以检索文件扩展名。.

类图像上载{

public function getExtension ($name)
{
    if($name){
    foreach ($name as $val){
        $fname=$val['name'];
      }
    $exts = split("[/\\.]", $fname) ;
    $n = count($exts)-1;
    $exts = $exts[$n];
    return $exts; 
    }

}

}

在控制器中:

类profilecontroller扩展zend_controller_操作 { 函数indexaction() { $this->查看->title=“个人资料”; $this->查看->bodycopy=“

请填写这张表。

“;

    $form = new ImgForm();

    if ($this->_request->isPost()) {
        $formData = $this->_request->getPost();
        if ($form->isValid($formData)) {
                $adapter = new Zend_File_Transfer_Adapter_Http();
                $adapter->setDestination('images/users/big');

                // getting extension

                $filename = $adapter->getFileInfo();
                $uhelper = new ImageUpload;  // cals for help to get file extension
                $extension = $uhelper->getExtension($filename); // got extension   


                 // success -- file handled

                 //rename
                 $auth = Zend_Auth::getInstance();
                 $identity = $auth->getIdentity();

                 $adapter->addFilter('Rename', array('target' => 'images/users/big/'.$identity->id.'.'.$extension,
                     'overwrite' => true));

                if (!$adapter->receive()) {
                 $form->addError($adapter->getMessages());

                }

        } else {
            $form->populate($formData);
        }
    }

    $this->view->form = $form;

}

当你的表格应该是:

    parent::__construct($options);
    $this->setName('upload');
    $this->setAttrib('enctype', 'multipart/form-data');


    $file = new Zend_Form_Element_File('file');
    $file->setLabel('File')
          ->addValidator('Count', false, 1)     // ensure only 1 file
          ->addValidator('Size', false, 102400) // limit to 100K
          ->addValidator('Extension' ,false, 'jpg,png,gif') // only JPEG, PNG, and GIFs

          ->setRequired(true);          


    $submit = new Zend_Form_Element_Submit('submit');
    $submit->setLabel('Upload');

    $this->addElements(array($file, $submit));

}

}

玩得高兴

public function getExtension($name){
    $names= explode(".", $name);
    return $names[count($names)-1];
}

在调用适配器之前,我必须截取$\u文件并进行更改。

if(isset($_FILES['file1'])){
  $ext = pathinfo($_FILES['file1']['name']);
  $_FILES['file1']['name'] = 'image_'. $userid .'.'.$ext['extension'];
}
$adapter = new Zend_File_Transfer_Adapter_Http();

我相信有更好的方法,我不知道为什么过滤器不工作,我已经尽力让它工作。我有一个最后期限,所以上面的代码变成了LOL

希望它能帮助别人
