我用symfony1.0开发，我正在使用文件验证（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，我希望在数据库进行数据处理之前从无效字符中清除名称？
修改
当然不是这样现在我在DB中使用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;
}
EDIT-2 ：
所以现在我有很多存储在数据库中的图像名称与invlaid charater，所以我希望创建一个脚本或方法来传播所有数据在feald“image_name”并直接更改DB中的所有无效字符，我的第一个想法是使用“任务”？！任何想法？
EDIT-3 ：
所以现在我按照那样制作我的批次：
<?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更改无效字符，我的新问题是如何在他的目录中更改文件名，我的意思是更改文件本身的文件名，我不知道怎么办？
修改-4
所以这是我的最终代码：
批次/ updatelogoName.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 **********************************/

}
return $fileName;

public static function cleanName ($fileName)

$extremove = self::RemoveExtension($fileName);
$result = self::stripText($extremove);
$finaleFileName= $result.'.'.$extension;
return $finaleFileName;

public static function cleanUrl($fileName,$filePath)

return $finaleFilePath;
}
如果您发现任何错误或优化，请告诉我......
答案 0 :(得分：2)
您可以使用striptext方法在generateUniqueName函数中清理文件名。例如，Askeet中使用的那个：
<?php
class myTools
{
public static function stripText($text)
{
$text = strtolower($text);
// strip all non word chars
$text = preg_replace('/\W/', ' ', $text);
// replace all white space sections with a dash
$text = preg_replace('/\ +/', '-', $text);
// trim dashes
$text = preg_replace('/\-$/', '', $text);
$text = preg_replace('/^\-/', '', $text);
return $text;
}
}
然后：
public static function generateUniqueName($fileName, $fileExtension)
{
// Create a name
$fileUniqueSuffix = PublicIdGeneratorPeer::getPublicIdForTable(self::UNIQUE_FILE_ID);
$finalFileName = myTools::stripText($fileName).'-'.$fileUniqueSuffix.$fileExtension;
return $finalFileName;
}
修改：
对于第二个请求，您应该创建一个任务。事实上，这是一项任务，但在sf1.0中称为 batch 。见the short doc here。基本上是：
编辑2：
如果您对utf8有疑问，请与Doctrine_Inflector的urlize核对。
然后使用：
$finalFileName = Doctrine_Inflector::urlize($fileName).'-'.$fileUniqueSuffix.$fileExtension;
