我正在开发一个PHP上传脚本,允许.mp3文件上传等.我创建了一个数组,指定允许的文件类型,包括mp3,并设置最大上传限制为500MB：
// define a constant for the maximum upload size
define ('MAX_FILE_SIZE', 5120000);
// create an array of permitted MIME types
$permitted = array('application/msword', 'application/pdf', 'text/plain', 'text/rtf', 'image/gif', 'image/jpeg', 'image/pjpeg', 'image/png', 'image/tiff', 'application/zip', 'audio/mpeg', 'audio/mpeg3', 'audio/x-mpeg-3', 'video/mpeg', 'video/mp4', 'video/quicktime', 'video/x-ms-wmv', 'application/x-rar-compressed');
到目前为止,在测试中所有指定的文件类型都已成功上传,但由于某种原因,它会出现.mp3的错误.正如你在上面看到的那样,我已经包含了audio / mpeg,audio / mpeg3和audio / x-mpeg-3,但它们似乎没有任何区别.
有人可以建议问题是什么,并指出哪个音频类型是允许.mp3上传所需的音频类型？
谢谢
更新：我用来运行文件检查的代码如下：
// check that file is within the permitted size
if ($_FILES['file-upload']['size'][$number] > 0 || $_FILES['file-upload']['size'][$number] <= MAX_FILE_SIZE) {
$sizeOK = true;
}
// check that file is of an permitted MIME type
foreach ($permitted as $type) {
if ($type == $_FILES['file-upload']['type'][$number]) {
$typeOK = true;
break;
}
}
if ($sizeOK && $typeOK) {
switch($_FILES['file-upload']['error'][$number]) {
case 0:
// check if a file of the same name has been uploaded
if (!file_exists(UPLOAD_DIR.$file)) {
// move the file to the upload folder and rename it
$success = move_uploaded_file($_FILES['file-upload']['tmp_name'][$number], UPLOAD_DIR.$file);
}
else {
// strip the extension off the upload filename
$filetypes = array('/\.doc$/', '/\.pdf$/', '/\.txt$/', '/\.rtf$/', '/\.gif$/', '/\.jpg$/', '/\.jpeg$/', '/\.png$/', '/\.tiff$/', '/\.mpeg$/', '/\.mpg$/', '/\.mp4$/', '/\.mov$/', '/\.wmv$/', '/\.zip$/', '/\.rar$/', '/\.mp3$/');
$name = preg_replace($filetypes, '', $file);
// get the position of the final period in the filename
$period = strrpos($file, '.');
// use substr() to get the filename extension
// it starts one character after the period
$filenameExtension = substr($file, $period+1);
// get the next filename
$newName = getNextFilename(UPLOAD_DIR, $name, $filenameExtension);
$success = move_uploaded_file($_FILES['file-upload']['tmp_name'][$number], UPLOAD_DIR.$newName);
}
if ($success) {
$result[] = "$file uploaded successfully";
}
else {
$result[] = "Error uploading $file. Please try again.";
}
break;
case 3:
$result[] = "Error uploading $file. Please try again.";
default:
$result[] = "System error uploading $file. Contact webmaster.";
}
}
elseif ($_FILES['file-upload']['error'][$number] == 4) {
$result[] = 'No file selected';
}
else {
$result[] = "$file cannot be uploaded. Maximum size: $max. Acceptable file types: doc, pdf, txt, rtf, gif, jpg, png, tiff, mpeg, mpg, mp3, mp4, mov, wmv, zip, rar.";
}
我得到了底部的其他结果告诉我文件大小错误或者不允许扩展名.
更新2：
我运行了_FILES数组的print_r,希望能提供更多信息.结果是：
排列
(
[file-upload] =>排列
(
[name] =>排列
(
[0] => Mozart.mp3
[1] =>
[2] =>
)
[type] => Array
(
[0] => audio/mpg
[1] =>
[2] =>
)
[tmp_name] => Array
(
[0] => /Applications/MAMP/tmp/php/phpgBtlBy
[1] =>
[2] =>
)
[error] => Array
(
[0] => 0
[1] => 4
[2] => 4
)
[size] => Array
(
[0] => 75050
[1] => 0
[2] => 0
)
)
)
解决方法:
MAX_FILE_SIZE是字节值
5120000不是500 MB.据我估算,这是5MB.
你还需要检查你的php.ini文件中是否没有超过“post_max_size”和“upload_max_size”变量
其次,mp3可以是以下任何一种mimetypes
> audio / mpeg
> audio / x-mpeg
>音频/ mp3
> audio / x-mp3
> audio / mpeg3
> audio / x-mpeg3
> audio / mpg
> audio / x-mpg
> audio / x-mpegaudio
