建议的使用mime_type_guessers
使用不存在的功能。如果你想使用 sfValidatorFile 方法,你应该写array(array('sfValidatorFile', 'guessFromFileinfo'))
. 建议的解决方案根本不使用 mime 类型检测,并导致我系统上的经典 excel 格式出现问题。
我通过扩展 sfValidatorFile 类并更改 getMimeType 方法解决了这个问题。
在您的 lib 文件夹中创建一个新的 msValidatorFile.class.php 文件:
<?php
class msValidatorFile extends sfValidatorFile
{
protected function getMimeType($file, $fallback)
{
$arrayZips = array( "application/zip",
"application/x-zip",
"application/x-zip-compressed");
$officeTypes = array(
"application/vnd.ms-word.document.macroEnabled.12",
"application/vnd.openxmlformats-officedocument.wordprocessingml.document",
"application/vnd.openxmlformats-officedocument.wordprocessingml.template",
"application/vnd.ms-powerpoint.template.macroEnabled.12",
"application/vnd.openxmlformats-officedocument.presentationml.template",
"application/vnd.ms-powerpoint.addin.macroEnabled.12",
"application/vnd.ms-powerpoint.slideshow.macroEnabled.12",
"application/vnd.openxmlformats-officedocument.presentationml.slideshow",
"application/vnd.ms-powerpoint.presentation.macroEnabled.12",
"application/vnd.openxmlformats-officedocument.presentationml.presentation",
"application/vnd.ms-excel.addin.macroEnabled.12",
"application/vnd.ms-excel.sheet.binary.macroEnabled.12",
"application/vnd.ms-excel.sheet.macroEnabled.12",
"application/vnd.openxmlformats-officedocument.spreadsheetml.sheet",
"application/vnd.ms-excel.template.macroEnabled.12",
"application/vnd.openxmlformats-officedocument.spreadsheetml.template");
foreach ($this->getOption('mime_type_guessers') as $method)
{
$type = call_user_func($method, $file);
if (null !== $type && $type !== false)
{
if (in_array($type, $arrayZips) && in_array($fallback, $officeTypes))
{
return $fallback;
}
return strtolower($type);
}
}
return strtolower($fallback);
}
}
在您的表单代码中使用这个新的验证器:
$this->validatorSchema['file'] =
new msValidatorFile(array('required' => false,
'path' => sfConfig::get('sf_upload_dir')
));
