PHP-Symfony 1.4 sfThumbnail不生成缩略图

我有一个上传表单,效果很好,正在上传照片,但问题是sfThumbnail插件似乎无法正常工作.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'
            )
       ));

这是验证器类的

    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;
    }

而我的动作代码：

    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');
      }
    }
     }

我不确定100％是否正确执行了操作,但这是我从文档和其他示例中看到的内容.

解决方法:

您不能使用$this-> savedName,因为它是sfValidatedFile中的受保护值.您应该改用$this-> getSavedName().

我不明白这部分内容：

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

为什么要提取文件名,最后在用loadFile加载时将/ image /重新添加到文件名中？

无论如何,我对您的课进行了一些更改.我没有测试过,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;
  }
