File Upload and Download

[khaja.jab]

Hello Experts,

I have one problem in my file uploading script. that is i want to increase the upload size 512kb to 250mb. can any one help me please.
my code is:

<?
// Max size PER file in KB
$max_file_size="512";

// Max size for all files COMBINED in KB
$max_combined_size="2048";

//Maximum file uploades at one time
$file_uploads="4";

//The name of your website
$websitename="Your site name";

// Full browser accessable URL to where files are accessed. With trailing slash.
$full_url="http://YOUR_SITE/uploads/";

// Path to store files on your server If this fails use $fullpath below. With trailing slash.
$folder="./uploads/";

// Use random file names? true=yes (recommended), false=use original file name.
// Random names will help prevent files being denied because a file with that name already exists.
$random_name=true;

// Types of files that are acceptiable for uploading. Keep the array structure.
$allow_types=array("jpg","gif","png","zip","rar","txt","doc");

// Only use this variable if you wish to use full server paths. Otherwise leave this empty. With trailing slash.
$fullpath="";

//Use this only if you want to password protect your upload form.
$password="";

Hi

Change the two first parameters

$max_file_size = "256000";
$max_combined_size = "1024000";

This will make it possible to upload files that are in the size of 250mb and four files with the combined size of 1gb as the third parameter tells that four files can be uploaded at the same time.

[khaja.jab]

from that it was not uploading the file.

Please check this link for clarification.

[Argoo]

What kind of error do you get now? I tried to upload a file and it seems to work fine, the file was not in the size of 250mb though.

[khaja.jab]

when i was uploading 120mb file it was not uploading

[Argoo]

Do you get any errors? Maybe theres a limit on filesizes where you host your files?

[khaja.jab]

i am not getting any errors but it was showing blank.

When the upload was success it show the uploaded file path link.

try to upload one file, u will get idea

[Argoo]

I'm on a slow connection so i will not try upload a large file. Take a screenshot when you'r uploading.

[khaja.jab]

i am not getting error to show you, when i am uploading a large file then it was processing after sometime it was automatically stops the upload process. I am not understanding the exact error.

please check from yourself...
