我正在使用 symfony1.0 开发，我正在使用这样的文件验证（validate/upload.yml）：
methods:
post: [logo_file]
get: [logo_file]
names:
logo_file:
required: Yes
required_msg: Please select a file to upload 23008
validators: myFileValidator
file: true
myFileValidator:
class: sfFileValidator
param:
mime_types:
- 'image/jpeg'
- 'image/png'
- 'image/gif'
- 'image/x-png'
- 'image/pjpeg'
mime_types_error: Only PNG, GIF and JPEG images files are allowed 23009
max_size: 512000
max_size_error: Max size is 512Kb 23010
到目前为止一切都很好，但我还想对图像名称进行验证，我希望在输入数据库之前从无效字符中清除名称？

当然不是这样，现在我在 sving 在 DB 之前使用了一个函数：
public static function generateUniqueName($fileName, $fileExtension)
{
// Create a name
$fileUniqueSuffix=PublicIdGeneratorPeer::getPublicIdForTable(self::UNIQUE_FILE_ID);
$finalFileName = $fileName.'-'.$fileUniqueSuffix.$fileExtension;
//here I want to replace or remove invalid character from $filename
return $finalFileName;
}
编辑-2：
所以现在我有很多图像名称存储在数据库中，带有invlaid charater，所以我希望创建一个脚本或一种方法来传输feald“image_name”中的所有数据并直接更改数据库中的所有无效字符，我的第一个想法是使用“任务”？！任何想法？
编辑-3：
所以现在我像这样制作我的批次：
<?php
define('SF_ROOT_DIR', realpath(dirname(__FILE__).'/..'));
define('SF_APP', 'backend');
define('SF_ENVIRONMENT', 'prod');
define('SF_DEBUG', false);
// symfony directories
require_once(SF_ROOT_DIR.DIRECTORY_SEPARATOR.'apps'.DIRECTORY_SEPARATOR.SF_APP.DIRECTORY_SEPARATOR.'config'.DIRECTORY_SEPARATOR.'config.php');
sfContext::getInstance();
/********************************** Begin **********************************/
$criteria = new Criteria();
$listCompanyLogo = CompanyLogoPeer::doSelect($criteria);
foreach($listCompanyLogo as $CompanyLogo)
{
if(!is_null($CompanyLogo))
{
$filename= $CompanyLogo->getFileName();
$filepath=$CompanyLogo->getFilePath();
$fileurl=$CompanyLogo->getFileUrl();
$finalFileName=StringTool::stripText($filename);
$finalFilePath=StringTool::cleanUrl($filename,$filepath);
$finalFileUrl=StringTool::cleanUrl($filename,$fileurl);
$CompanyLogo->setFileName($finalFileName);
$CompanyLogo->setFilePath($finalFilePath);
$CompanyLogo->setFileUrl($finalFileUrl);
$CompanyLogo->save();
echo ' the name of logo : '.$filename.' is modified by ==============>'.$finalFileName.'<br>' ;
exit();
}
}
/********************************** End **********************************/
?>
所以我可以从数据库中的文件名中更改无效字符，我的新问题是如何更改他的目录中的文件名，我的意思是更改文件本身的文件名，我不知道如何？
编辑-4
所以这是我的最终代码：
批处理/更新logoName.php
<?php
define('SF_ROOT_DIR', realpath(dirname(__FILE__).'/..'));
define('SF_APP', 'backend');
define('SF_ENVIRONMENT', 'prod');
define('SF_DEBUG', false);
// symfony directories
require_once(SF_ROOT_DIR.DIRECTORY_SEPARATOR.'apps'.DIRECTORY_SEPARATOR.SF_APP.DIRECTORY_SEPARATOR.'config'.DIRECTORY_SEPARATOR.'config.php');
sfContext::getInstance();
/********************************** Begin **********************************/
$criteria = new Criteria();
$listCompanyLogo = CompanyLogoPeer::doSelect($criteria);
foreach($listCompanyLogo as $CompanyLogo)
{
if(!is_null($CompanyLogo))
{
$filename= $CompanyLogo->getFileName();
$filepath=$CompanyLogo->getFilePath();
$fileurl=$CompanyLogo->getFileUrl();
$thumbnailName= $CompanyLogo->getThumbnailName();
$ThumbnailPath= $CompanyLogo->getThumbnailPath();
$ThumbnailUrl= $CompanyLogo->getThumbnailUrl();
$finalFileName=StringTool::cleanName($filename);
$finalFilePath=StringTool::cleanUrl($filename,$filepath);
$finalFileUrl=StringTool::cleanUrl($filename,$fileurl);
$finalThumbnailName=StringTool::cleanName($thumbnailName);
$finalThumbnailPath=StringTool::cleanUrl($filename,$ThumbnailPath);
$finalThumbnailUrl=StringTool::cleanUrl($filename,$ThumbnailUrl);
$CompanyLogo->setFileName($finalFileName);
$CompanyLogo->setFilePath($finalFilePath);
$CompanyLogo->setFileUrl($finalFileUrl);
$CompanyLogo->setThumbnailName($finalThumbnailName);
$CompanyLogo->setThumbnailPath($finalThumbnailPath);
$CompanyLogo->setThumbnailUrl($finalThumbnailUrl);
$CompanyLogo->save();
if(rename('../web/'.$ThumbnailUrl, '../web/'.$finalThumbnailUrl) !== 'false')
{
rename('../web/'.$ThumbnailUrl, '../web/'.$finalThumbnailUrl);
}
echo 'The logo : '.$filename.' is modified by ==============>'.$finalFileName.'<br>' ;
}
}
/********************************** End **********************************/
?>
