maxNumberOfFiles: 6
});

maxNumberOfFileswas not working for me so i did the following
maxNumberOfFiles对我不起作用所以我做了以下
$('#fileuploadbasic').fileupload({
change : function (e, data) {
if(data.files.length>=5){
alert("Max 5 files are allowed")
return false;
}
},
maxFileSize: 20000000,
acceptFileTypes: /(\.|\/)(jpe?g|png)$/i,
});

You can limit the uploading files by the "Uploadhandler.php" file .change the "max_number_of_files" option. works for me. But it only validates when you upload the file.
您可以通过“Uploadhandler.php”文件限制上传文件。更改“max_number_of_files”选项。为我工作。但它仅在您上传文件时进行验证。

If you are using the "Krajee" fileupload, then you will have to use
如果您使用的是“Krajee”文件上传，则必须使用
$('#fileuploadbasic').fileinput({
maxFileCount: 6
});
If set to 0, it means size allowed is unlimited. Defaults to 0.
如果设置为 0，则表示允许的大小不受限制。默认为 0。

You can try:
你可以试试：
$('#fileuploadbasic').fileupload({
//.....
paramName: 'your_input_name',
add : function (e, data) {
if(data.paramName != undefined) data.submit();
}
});
