Symfony 1.4 sfThumbnail 不生成缩略图

Question

我有一个上传表单，效果很好，照片正在上传，但问题是 sfThumbnail 插件似乎不起作用。没有生成缩略图。这是我的代码：

      // /lib/form/UploadForm.class.php

      public function configure()
      {
      $this->setWidget('photo', new sfWidgetFormInputFileEditable(
      array(
        'edit_mode' => !$this->isNew(),
        'with_delete' => false,
        'file_src' => '',
         )
      ));

      $this->widgetSchema->setNameFormat('image[%s]');

      $this->setValidator('photo', new sfValidatorFile(
        array(
        'max_size' => 5000000,
        'mime_types' => 'web_images', 
        'path' => '/images/',
        'required' => true,
        'validated_file_class' => 'sfMyValidatedFileCustom'
            )
       ));

这里是验证器类

    class sfMyValidatedFileCustom extends sfValidatedFile{

    public function save($file = null, $fileMode = 0666, $create = true, $dirMode = 0777) 
    {
      $saved = parent::save($file, $fileMode, $create, $dirMode);
      $thumbnail = new sfThumbnail(150, 150, true, true, 75, '');
      $location = strpos($this->savedName,'/image/');
      $filename = substr($this->savedName, $location+15); 
      // Manually point to the file then load it to the sfThumbnail plugin
      $uploadDir = sfConfig::get('sf_root_dir').'/image/';
      $thumbnail->loadFile($uploadDir.$filename);
      $thumbnail->save($uploadDir.'thumb/'.$filename,'image/jpeg');
      return $saved;
    }

还有我的操作代码：

    public function executeUpload(sfWebRequest $request)
    {
    $this->form = new UploadForm();
    if ($request->isMethod('post'))
    {
      $this->form->bind(
        $request->getParameter($this->form->getName()),
        $request->getFiles($this->form->getName())
      );
      if ($this->form->isValid())
      {
           $this->form->save();
           return $this->redirect('photo/success');
      }
    }
     }

我不能 100% 确定我是否正确执行此操作，但这是我从文档和其他示例中看到的。

您不能使用$this->savedName，因为它是来自sfValidatedFile 的受保护值。你应该改用$this->getSavedName()。

我不明白这部分：

$location = strpos($this->savedName,'/image/');
$filename = substr($this->savedName, $location+15);

为什么要提取文件名，最后在使用loadFile 加载时重新添加/image/？

无论如何，我对你的班级做了一些改变。我没有测试它，但我认为它应该可以工作。

class sfMyValidatedFileCustom extends sfValidatedFile
{
  public function save($file = null, $fileMode = 0666, $create = true, $dirMode = 0777) 
  {
    $saved    = parent::save($file, $fileMode, $create, $dirMode);
    $filename = str_replace($this->getPath().DIRECTORY_SEPARATOR, '', $saved);

    // Manually point to the file then load it to the sfThumbnail plugin
    $uploadDir = $this->getPath().DIRECTORY_SEPARATOR;

    $thumbnail = new sfThumbnail(150, 150, true, true, 75, '');
    $thumbnail->loadFile($uploadDir.$saved);
    $thumbnail->save($uploadDir.'thumb/'.$filename, 'image/jpeg');

    return $saved;
  }
