Trying upload large file from formData

Question

I trying upload large file (over 200mb) via FormData and xmlHTTPRequest like this

var fd = new FormData;
fd.append('files[]', file);

xmlHttpRequest.open("POST", url, true);
xmlHttpRequest.send(fd);

in php script i have

<?php
var_dump("IN");
var_dump($_FILES);

out:

IN
array()

Request wait 10 second and finish. With smaller files all good, without FormData (simple ajax from) all good. all settings in php.ini have max value. what's wrong?

if it can help, this is my request header:

Accept  text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Encoding gzip, deflate
Accept-Language ru-RU,ru;q=0.8,en-US;q=0.5,en;q=0.3

My /etc/php5/apache2/php.ini:

file_uploads = On
upload_max_filesize = 512M
max_file_uploads = 20
max_input_time = 10000
memory_limit = 2048M
max_execution_time = 10000
post_max_size = 1024M

My scripts link: http://www.megafileupload.com/en/file/430866/test1-tar-gz.html

PS It's run all times 10 seconds and then finish.

Answer 1

Without seeing your php.ini file, these are things that will affect upload and you need to change them accordingly

file_uploads
upload_max_filesize
max_input_time
memory_limit
max_execution_time 
post_max_size

All those settings have to have a reasonably high setting for larger files. Becareful not to make your memory_limit too high which can be dangerous. I'd maybe do 128MB . max_execution_time is forgotten by many and the default is 30 secs. Not long enough for large files. I set mine to 1000 since I handle large videos. It is a common reason why the script doesn't finish and will finish prematurely. You may or may not have to restart your web server.
