Total file size for multiple instances
August 20, 2008 - 10:45pm — ctong
I have multiple SWFUpload instances on a page and each has it's own file size limit. However, I would like to calculate the total file size for all the instances so that I can control the total limit. Is it possible to return the file size of each instance before the upload begin?

Sure
There is an array called SWFUpload.instances that keeps a reference to all the SWFUPload instances you've created.
You can loop through this array and call "getFile" on each index and get the file size.
Something like this (pseudo code):
var totalFileSize = 0;
var totalFileCount = 0;
for (var instance in SWFUpload.instances) {
var fileIndex = 0;
var file = instance.getFile(fileIndex++);
while (file !== null) {
if (file.filestatus === SWFUpload.FILE_STATUS.QUEUED) {
totalFileCount++;
totalFileSize += file.size;
}
file = instance.getFile(fileIndex++);
}
}
