Chucked upload not working.

[mcfriend99]

Only the first chance in a chucked upload gets uploaded. Here is my code:

$extension = pathinfo($_FILES['video']['name'], PATHINFO_EXTENSION);

    // Simple validation (max file size 2MB and only two allowed mime types)
    $validator = new FileUpload\Validator\Simple('200M', [
        'video/x-flv', // .flv
        'video/mp4', // .mp4
        'application/x-mpegURL', // iphone .mp4, .mpu
        'video/MP2T', // iphone .ts
        'video/3gpp', // .3gp videos
        'video/3gpp2', // .3gp, .3gp2, .3gpp videos
        'video/quicktime', // .mov
        'video/x-msvideo', // .avi
        'video/webm', // .webm
        'video/webm', // .webm
        'video/ogg', // .ogg
        'video/x-matroska', // .mkv
        'video/x-ms-wmv' // .wmv
    ]);

    // Simple path resolver, where uploads will be put
    $pathresolver = new FileUpload\PathResolver\Simple('../../contents/videos/');

    // The machine's filesystem
    $filesystem = new FileUpload\FileSystem\Simple();

    // FileUploader itself
    $fileupload = new FileUpload\FileUpload($_FILES['video'], $_SERVER);

    $filename = time() . preg_replace('/[^a-zA-Z0-9_]+/', '_',  preg_replace('/[.]' .$extension. '$/', '', trim($_FILES['video']['name'])));
    $filenamegenerator = new FileUpload\FileNameGenerator\Custom($filename  . '.mp4');

    // Adding it all together. Note that you can use multiple validators or none at all
    $fileupload->setPathResolver($pathresolver);
    $fileupload->setFileSystem($filesystem);
    $fileupload->addValidator($validator);
    $fileupload->setFileNameGenerator($filenamegenerator);

    /*// 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]);

    $fileupload->addCallback('completed', function(FileUpload\File $file) {
echo $file->getRealPath();
});

Getting Internerla Server error issue when the file size is higher than my maxChunckSize.

Here is my Javascript:

$('#fileupload').fileupload({
    maxChunkSize: 10000000, // 10 MB
    add: function (e, data) {
        var that = this;
        $.getJSON('server/php/', {file: data.files[0].name}, function (result) {
            var file = result.file;
            data.uploadedBytes = file && file.size;
            $.blueimp.fileupload.prototype
                .options.add.call(that, e, data);
        });
    }
});

Is it even working the example code in https://github.com/blueimp/jQuery-File-Upload/wiki/Chunked-file-uploads?

The mime type validation does not work.

[mcfriend99]

Don't understand you. Are you saying I should simply implement my own validation?

[adelowo]

@mcfriend99, @Paradinight is right.. There's no way the mime type validator would work with chucked uploads (the second time the upload is restarted ) because partially uploaded files usually have an invalid mime type since they are incomplete .. Hence validation would fail.

Resuming a partially uploaded file is a tradeoff between "usability and security "

adelowo you could check the $_FILE mime type, if incorrect throw an error. After complete upload check the mime type again, but this time with php. The First check is for the usability and the second for the security.
