Question

我有一个产品表单，用户可以同时上传5张图片。一切都工作正常，但我正在尝试实现sfThumbnail插件，以便它同时创建每个图片的缩略图。下面的代码适用于Picture1，但Picture2,3,4和5不适用。我已经尝试搞乱代码，我不能让它单独使用每个文件。它只是以Picture2的上传文件为例，它的名称与图片1相同。所以当它运行时，我最终得到5张上传的图片，但只有1张缩略图，带有第一张图片的文件名。

我尝试复制代码5次并为每张图片自定义但我得到了相同的结果。

如果有更有效的方法，请告诉我。这正是我从插件文档中得到的。感谢

if($this->isModified())
    {
      $uploadDir = sfConfig::get('sf_upload_dir');
      $thumbnail = new sfThumbnail(150, 150);
      $thumbnail->loadFile($uploadDir.'/car/'.$this->getPicture1());
      $thumbnail->save($uploadDir.'/car/thumbnail/'. $this->getPicture1());
    }

Answer 1

这对我有用：

if($this->isModified())
    {
      $uploadDir = sfConfig::get('sf_upload_dir');
      $thumbnail = new sfThumbnail(150, 150);
      if($this->getPicture1())
      {
        $thumbnail->loadFile($uploadDir.'/car/'.$this->getPicture1());
        $thumbnail->save($uploadDir.'/car/thumbnail/'. $this->getPicture1());
      }

      if($this->getPicture2())
      {
        $thumbnail->loadFile($uploadDir.'/car/'.$this->getPicture2());
        $thumbnail->save($uploadDir.'/car/thumbnail/'. $this->getPicture2());
      }

.. the rest of my the pictures
    }

首先删除你的功能：

if($this->isModified())
    {
      $uploadDir = sfConfig::get('sf_upload_dir');
      $thumbnail = new sfThumbnail(150, 150);
      $thumbnail->loadFile($uploadDir.'/car/'.$this->getPicture1());
      $thumbnail->save($uploadDir.'/car/thumbnail/'. $this->getPicture1());
    }

在你的表单类中插入此函数：

protected function processUploadedFile($field, $filename = null, $values = null) {

          // prendo il file che è stato caricato
          $fn = parent::processUploadedFile( $field, $filename, $values );

          // se il file esiste ed
          if ( $fn != "" ) {

               try {

                  // array multidimensionale di tutte le tipologie di thumb esistenti
                  $thumbnails[] = array( 'dir' => 'ico',           'width' => 75,      'height' => 75 );
                  $thumbnails[] = array( 'dir' => 'small',      'width' => 150, 'height' => 150 );
                  $thumbnails[] = array( 'dir' => 'medium',      'width' => 400, 'height' => 400 );
                  $thumbnails[] = array( 'dir' => 'big',           'width' => 800, 'height' => 800 );

                  foreach ( $thumbnails as $thumbParam )
                  {
                    $currentFile = sfConfig::get( 'sf_upload_dir' ).'/destination_folder/'.$thumbParam[ 'dir' ].'/'. $fn;
                    if ( is_file( $currentFile ) ) unlink( $currentFile );
                  }

                  foreach ( $thumbnails as $thumbParam )
                  {
                      $thumbnail = new sfThumbnail( $thumbParam[ 'width' ], $thumbParam[ 'height' ], true, false );
                      $thumbnail->loadFile( sfConfig::get( 'sf_upload_dir' )."/destination_folder/original/".$fn );
                      $thumbnail->save( sfConfig::get( 'sf_upload_dir' ).'/destination_folder/'.$thumbParam[ 'dir' ].'/'.$fn, 'image/jpeg' );
                  }

               } catch( Exception $e ) {

               }
          }

          return $fn;
     }

其中：
- $thumbnails[]数组包含您需要的所有文件夹，包含尺寸，因此您需要所有的拇指 - 您之前需要在web / uploads目录中创建destination_folder文件夹

还记得调用命令

php symfony project:permissions

此功能获取表单中的所有文件，并根据需要生成任意数量的鼠标
