PHP FileUpload library that supports chunked uploads
PHP FileUpload library that supports chunked uploads. Adopted from the procedural script included with jQuery-File-Upload, designed to work with that JavaScript plugin, with normal forms, and to be embeddable into any application/architecture.
This package is available via Composer:
{ "require": { "gargron/fileupload": "~1.4.0" } }
Ensure that the PHP extension "php_fileinfo" is enabled;
Your php.ini must have the next directive:
file_uploads = On
The unit test suite covers simple uploads and the library "works on my machine", as it were. You are welcome to contribute.
You can grep the source code for
TODOto find things you could help finishing.
// Simple validation (max file size 2MB and only two allowed mime types) $validator = new FileUpload\Validator\Simple('2M', ['image/png', 'image/jpg']);// Simple path resolver, where uploads will be put $pathresolver = new FileUpload\PathResolver\Simple('/my/uploads/dir');
// The machine's filesystem $filesystem = new FileUpload\FileSystem\Simple();
// FileUploader itself $fileupload = new FileUpload\FileUpload($_FILES['files'], $_SERVER);
// Adding it all together. Note that you can use multiple validators or none at all $fileupload->setPathResolver($pathresolver); $fileupload->setFileSystem($filesystem); $fileupload->addValidator($validator);
// Doing the deed list($files, $headers) = $fileupload->processAll();
// Outputting it, for example like this foreach($headers as $header => $value) { header($header . ': ' . $value); }
echo json_encode(['files' => $files]);
foreach($files as $file){ //Remeber to check if the upload was completed if ($file->completed) { echo $file->getRealPath();
// Call any method on an SplFileInfo instance var_dump($file->isFile()); }
}
$factory = new FileUploadFactory( new PathResolver\Simple('/my/uploads/dir'), new FileSystem\Simple(), [ new FileUpload\Validator\MimeTypeValidator(['image/png', 'image/jpg']), new FileUpload\Validator\SizeValidator('3M', '1M') // etc ] );$instance = $factory->create($_FILES['files'], $_SERVER);
There are currently 4 validators shipped with
FileUpload:
Simple```php // Simple validation (max file size 2MB and only two allowed mime types) $validator = new FileUpload\Validator\Simple('2M', ['image/png', 'image/jpg']);
- `MimeTypeValidator` ```php $mimeTypeValidator = new FileUpload\Validator\MimeTypeValidator(['image/png', 'image/jpg']);
SizeValidator
php // The 1st parameter is the maximum size while the 2nd is the minimum size $sizeValidator = new FileUpload\Validator\SizeValidator('3M', '1M');
DimensionValidator```php $config = [ 'width' => 400, 'height' => 500 ]; // Can also contain 'minwidth', 'maxwidth', 'minheight' and 'maxheight'
$dimensionValidator = new FileUpload\Validator\DimensionValidator($config); ```
Remember to register new validator(s) by
$fileuploadInstance->addValidator($validator);
If you want you can use the common human readable format for filesizes like '1M', '1G', just pass the string as the first argument.
$validator = new FileUpload\Validator\Simple('10M', ['image/png', 'image/jpg']);
Here is a listing of the possible values (B => B; KB => K; MB => M; GB => G). These values are binary convention so basing on 1024.
With the
FileNameGeneratoryou have the possibility to change the filename the uploaded files will be saved as.
$fileupload = new FileUpload\FileUpload($_FILES['files'], $_SERVER); $filenamegenerator = new FileUpload\FileNameGenerator\Simple(); $fileupload->setFileNameGenerator($filenamegenerator);
Custom
php $customGenerator = new FileUpload\FileNameGenerator\Custom($provider); //$provider can be a string (in which case it is returned as is) //It can also be a callable or a closure which receives arguments in the other of $source_name, $type, $tmp_name, $index, $content_range, FileUpload $upload
MD5
php $md5Generator = new FileUpload\FileNameGenerator\MD5($allowOverride); //$allowOverride should be a boolean. A true value would overwrite the file if it exists while a false value would not allow the file to be uploaded since it already exists.
Random```php $randomGenerator = new FileUpload\FileNameGenerator\Random($length); //Where $length is the maximum length of the generator random name
- `Simple` ```php $simpleGenerator = new FileUpload\FileNameGenerator\Simple(); //Saves a file by it's original name
Slug
php $slugGenerator = new FileUpload\FileNameGenerator\Slug(); //This generator slugifies the name of the uploaded file(s)> Remember to register new validator(s) by
$fileuploadInstance->setFileNameGenerator($generator);
Every call to
setFileNameGeneratoroverrides the currently set$generator
Currently implemented events:
completed
php $fileupload->addCallback('completed', function(FileUpload\File $file) { // Whoosh! });
beforeValidation
php $fileUploader->addCallback('beforeValidation', function (FileUpload\File $file) { // About to validate the upload; });
afterValidation
php $fileUploader->addCallback('afterValidation', function (FileUpload\File $file) { // Yay, we got only valid uploads });
The reason why the path resolver, the validators and the file system are abstracted, is so you can write your own, fitting your own needs (and also, for unit testing). The library is shipped with a bunch of "simple" implementations which fit the basic needs. You could write a file system implementation that works with Amazon S3, for example.
